The end of the year is the time to summarize，In the Provincial Real Estate Development Service Corporation，This year’s summary makes people particularly happy，The company’s ten-year Lubotan saline-alkali land transformation project successfully passed the achievement appraisal of the Provincial Department of Science and Technology，Exciting。

Provincial Real Estate Development Services Corporation actively implements the Scientific Outlook on Development，Under the leadership of Shaanxi Provincial Department of Land and Resources，Completed Lubotan land consolidation project，Not only added 10,200 acres of cultivated land，At the same time, we cooperated with Xi'an University of Technology to explore a way to "change discharge into storage、Coexistence of water and land、A new model of saline-alkali land management with harmonious ecology，Reached the international advanced level of similar research。Promotion and application of the comprehensive management results of Lubotan saline-alkali land，It will have a revolutionary impact on the management and development of 370,000 acres of saline-alkali land in the province，Generate huge economy、Social and ecological benefits。

former salt flats  Today’s prosperous land

Lubotan is located at the junction of Fuping County and Pucheng County, Shaanxi Province，Total area 12.240,000 acres,70% is saline-alkali land,Based on data from the 1986 land survey，2 of them.370,000 acres of unused land，30,000 acres of intermittent planting,4.340,000 acres of low-yield fields。The predecessor of Lubotan is Luyang Lake，For a long time, it was the only inland lake in Qinchuan within 800 miles。Fisheries and salt shipping,Yangliu Dutou，Not only was it rich at that time，Poetic and picturesque。Old annals record: “In the tenth year of the Tang Dynasty, the frozen pond produced auspicious salt。”To the end of Ming Dynasty，Luyang Lake is dying slowly、Shrinking into a beach。Eight Years of Anti-Japanese War，The salt produced in Lubotan once strongly supported the anti-Japanese military operations in northern Shaanxi。

The soil chemical type of Lubotan is chloride sulfate，The beach is rich in Glauber's salt。The soil has long been composed of moderately saline soil and heavily saline fluvoid soil，Testing data of unorganized soil from Northwest A&F University in 2001，Average soil organic matter content 0.70%，The average salt content is 0.774%，The average pH is 9.33。This is a continental dry climate,The annual evaporation is 1000 mm-1300 mm，It is 2 times to 3 times the rainfall。

In the eyes of locals，This tens of thousands of acres of land is nothing more than worthless: plant it，The grain harvested is only a few more grains than the seeds sown。Don’t plant it，Watching so much land idle！It’s really “summer and autumn”，The vast whiteness of winter and spring”，"Only saltgrass grows，Does not grow cotton or grain”。

1998,"Dynamic balance of total cultivated land" is written into the newly revised "Land Management Law"，Article 41 clearly stipulates: “The state encourages land consolidation。”Afterward，The "Decision" of the Third Plenary Session of the 15th Central Committee of the Communist Party of China pointed out: "We must focus on the transformation of medium and low-yield fields，Centralized contiguous management，Strive to achieve guaranteed harvests despite droughts and floods on most cultivated land in plain areas、High and stable production。”such，Land consolidation in market economy，It is a practical need，There is another dafabet mobile logininstitutional guarantee，A vast world opens up in front of people who are interested in engaging in land consolidation。Facing this，Provincial Real Estate Opening Service Corporation is keenly aware of business opportunities。Ten years of hard work is unusual，Let Lubo Beach completely change its appearance！

Today，Look around，As far as the eye can see, there are square and standard fields。Heavy ears of wheat、Endless cotton fields、Various water birds playing in the ditch beside the field、Small trees growing up year by year on the roadside、Busy farmers in the fields、Farmers fishing leisurely by the water、The old people and children wandering around to look at the scenery...these changes in life in the four seasons of spring, summer, autumn and winter and the bustling crowds coming and going，They are all proving to us silently: Lubotan，We have completely said goodbye to the desolation and death that lasted for hundreds of years，turned into a paradise full of life！

Scientific planning  Careful implementation

Early 1999，A cold and ordinary day，But it left warm memories。The leaders of Shaanxi Real Estate Development Services Corporation accompanied Tan Daofa, the former director of Shaanxi Provincial Land Management Bureau，Go to the Ministry of Land and Resources to report on work，When talking about the company’s development strategy，The then Vice Minister Li Yuan said to Tan Daofa: "The new Land Management Law has brought the dynamic balance of total cultivated land into the legal track，Land development and consolidation is an emerging industry，has broad prospects，Your company can shift its main business to land development and consolidation projects。"These words made the company leader stunned

Open.

April of the same year,Shaanxi Provincial Land Bureau held a meeting of prefectural and municipal land bureau chiefs in Xi'an，Deployment and implementation of the new Land Management Law，The meeting reached a consensus: increase effective cultivated land，Ensuring a balance between farmland occupation and compensation，New management and organizational forms for farmland development and organization should be actively explored，Carry out pilot project of farmland development industrial model。After this meeting，Shaanxi Real Estate Development Service Company

Visited 6 sites，Visiting consulting experts、Lead more than 50 people，After repeated analysis、Arguments and comparisons，Decided to develop land in Fuping Lubo Beach and Dali County Shayuan。The total planned development area of ​​Luobotan is 8,700 acres，Implemented in three phases，The first phase of development is 2,700 acres，Phase II development of 3,000 acres，The third phase of development: 3,000 acres，It is estimated that approximately 6,600 acres of new cultivated land will eventually be achieved。

April 5, 1999，Shaanxi Real Estate Development Services Corporation，Submit a project application to the former Shaanxi Provincial Land Management Bureau，Requesting approval for industrial development of 6,600 acres of land in Lubotan, Fuping County，The first phase plans to cultivate 2,000 acres of farmland。

May 7, 1999，The former Shaanxi Provincial Land Administration Bureau approved the implementation of the project by Shaanxi Real Estate Development Services Corporation，And the project was listed as the 1999 provincial farmland reclamation pilot project。

Then Shaanxi Real Estate Development Services Corporation held a general manager office meeting on May 8, 1999，Concretely study and deploy the implementation work of this project。The "Shaanxi Real Estate Development Services Corporation Lubotan Land Reconstruction Project Department" was established。

1999 6 A grand opening ceremony was held at the Lubotan construction site on March 18th。The then member of the Standing Committee of the Shaanxi Provincial Committee of the Communist Party of China、Sun Anhua, Secretary of the Provincial Political and Legal Committee、Zhou Tiehuan, Deputy Director of the Provincial Department of Justice、Tan Daofa, former director of the Provincial Land Management Bureau、Deputy Director Meng Jianguo and leaders of various bureau offices、Provincial Labor Reeducation Bureau、Weinan City、Main leaders of Fuping County Government and other units as well as Shaanxi TV Station、Shaanxi Daily、Reporters from China Land News and other news organizations attended the groundbreaking ceremony。Sun Anhua delivered an important speech，Tan Daofa issued the order to start construction，Lubotan land development project officially started。

At first，The company entrusted the construction design by the Water Conservancy and Hydropower Civil Engineering Research and Design Institute of Xi'an University of Technology，Following the practice of saline-alkali land management in the northwest inland，Emphasis on flushing and drainage，The focus of the project is to open more than 30 kilometers of alkali drainage channels from the project area to Luohe River。According to the plan, the project should first build roads and provide electricity，Then make sure the alkali drainage channel is clear，Rematching well、Irrigation channels, forest nets and other facilities。The standard field area does not exceed 60 acres，400 meters long from north to south，100 meters long from east to west。A total of 55 small trenches need to be excavated and laid out，An area of ​​more than 300 acres，Constitute a farmland water storage ditch network。

During project implementation，Leaders from the Ministry of Land and Resources and Shaanxi Province have visited the construction site many times to inspect and provide guidance，Fully affirmed the Lubotan land reclamation and development dafabet loginproject: December 19, 1999，Deputy Secretary-General of the Shaanxi Provincial Government Jia Xiang, accompanied by Tan Daofa, former director of the Provincial Land Management Bureau, inspected the planting situation of the newly developed land in Lubotan；March 15, 2000，Deputy Minister of Land and Resources Lu Xinshe and Deputy Secretary-General of the Provincial Government Xue Hanjun、Former Provincial Land Management Bureau Director Tan Daofa and others accompanied him

The same person inspected the construction site；April 25, 2000，The then Vice Minister of Land and Resources, Sun Wensheng, inspected the Lubotan Deep Water Well Project of the Weibei Water Search Project。

As of June 2001，一、The second phase of the project developed a total of 3822 saline-alkali wastelands.4 acres，Added high-standard irrigated land 3095.3 acres，Transportation land 187.1 mu，includes irrigation canals、The water area including the reservoir and alkali drainage ditch is 328.6 acres，Other land (including protective forest land) 212 acres。channel、路、Lin、Ditch、Tiangou connected into one，The engineering and technical aspects are clean and beautiful。

Breaking tradition  Bold innovation

Facing the initially sorted land，The decision-makers of the Provincial Real Estate Development Service Company have mixed feelings。The traditional way of treating alkali has always been that，The success or failure of saline-alkali land treatment projects，It depends on whether the water can be drained out。row、irrigation、flat、A series of engineering measures for fertilizer，The core is in "platoon"。The original design of the drainage channel leading to the Luo River was dozens of kilometers long，Large workload，Long construction period，Follow-up funds cannot be guaranteed，The salt-alkali water that cannot be drained is lingering and rippling in the ditches in the fields。While everyone is depressed because they see the hopelessness of the drainage system，Hongjiannao, which is protected as an ecological zone, flashed through the mind of the project leader，Their thinking suddenly turned 180 degrees: Why should the water be drained？Who said alkaline water is not a resource？

"In arid and semi-arid areas，High evaporation，Farmers have to use alkaline water to protect seedlings as a last resort。"They recalled their thoughts at the time，Explained to reporters: "Saline-alkali water is also a precious resource。This is the retreat area of ​​Erhuang Irrigation District，Including open water and diving，The open water is the water that cannot be poured out and retreats here through the channel，The diving water is discharged here through underground infiltration，There is much more to diving than open water。I thought of turning diving into open water，This makes the volume of water smaller。There is a lot of evaporation here，Just started，There is almost no water in the alkali drainage channel，Later, the water followed the terrain，Now there is water as soon as you dig it，Mingshui is generally increasing。”

After repeated research、Consultation、Discussion，The company canceled the construction of the drainage system in the original design,Including a high-level regulating pool covering an area of ​​200 acres、Intercepting drainage ditch、Surfaced dams and other engineering facilities originally planned for drainage。That’s it，"Water and soil distribution coexistence、Mainly storing，A new model of self-healing saline-alkali land consolidation and ecological restoration,In the stumbling blocks of practice，came to Lubotan in a critical state between natural selection and human decision-making。

Such a bold decision makes the project implementers feel uneasy，After all, this is related to the future of thousands of acres of land，Related to the success or failure of the entire project，Could the water accumulated on the edge of the fields be the Sword of Damocles hanging on Lubo Beach？Can the salt-alkali molecules in the water stay so honest?，Will the newly prepared land be cultivated for a few years before returning to alkaline state，Return everything to its original shape？

June 21, 2001，After the project is accepted by the Provincial Department of Land and Resources,In order to better summarize experience，Shaanxi Provincial Real Estate Development Services Corporation has formulated field soil and water crops in the Lubotan pilot area

Monitoring plan。Assign a dedicated person to be responsible for field observation experiments,Mainly targeted at soil during utilization、Water、Crop growth (yield) and other changes，A total of 7 long-term soil profile observation pits were set up,10 water sample testing points for water storage ditches，At the same time, crop growth in the test area、Year-by-year statistics and analysis of yield and daily rainfall。5-year period,A total of 60 soil sample tests completed,3360 test samples，

Test water samples 60 times and 600 samples.

5 years，The pH value of the soil is basically stable at 8.About 30;Full salt is basically 0.Below 2%；In a normal year，The emergence rate of cotton has increased from 40% to more than 90%，Cotton seed cotton output increased from 150 catties/mu in 2002 to 400 catties/mu in 2006；The land contract price is also determined by

The price increased from 40-80 yuan/mu in 2001 to 180-200 yuan/mu in 2006。

2006，With the strong support of the new party group of the Shaanxi Provincial Department of Land and Resources，Shaanxi Real Estate Development Services Corporation has intensified dafabet loginits land development and consolidation work while summarizing research。Director Wang Registration、Deputy Director Yan Chonglou and other leaders conducted multiple on-site inspections、Provided a lot of guidance、

Requesting more in-depth research and promotion work。November 2006-September 2008，Shaanxi Real Estate Development Services Corporation has expanded and implemented the third phase of the project on the basis of the original first and second phases、The fourth phase of the project (twenty-two projects)，Completed in October 2007 and September 2008 respectively and passed the acceptance of the Provincial Department of Land and Resources。

Starting from March 2007,The Provincial Real Estate Development Service Corporation completely overturned the past methods in Yanchiwa, Dali County,The fourth phase of the reconstruction project was successfully implemented based on the practical experience of Lubotan land reclamation，

A total management area of ​​4800 acres，More than 4,500 acres of newly added farmland，Taiwan and water storage canal coexist，Tai Tianli next to the water storage channel，The crops are growing very well；The saline-alkali water in the water storage channel did not cause any bad effects on the crops。

Achievements  Significant

Golden Autumn October 2008，Hosted by the Shaanxi Provincial Department of Science and Technology，Organized a scientific and technological appraisal of the results of the "Research and Practice on the Harmonious Ecological Model for Comprehensive Management of Saline-alkali Lands in Lubotan, Shaanxi Province" completed by the Provincial Real Estate Development Service Corporation and Xi'an University of Technology。The appraisal committee is composed of members of the Standing Committee of the National People's Congress、Professor Suo Lisheng, former Vice Minister of the Ministry of Water Resources，Composed by Shan Lun, academician of the Chinese Academy of Engineering, etc.。The appraisal opinion believes that "this achievement governance model has a breakthrough，Innovative theoretical research，Engineering practice is effective，The results have generally reached the international advanced level of similar research"。

The shining point of the new mode: change "row" to "accumulate"，Create a harmonious ecological environment。Lubotan saline-alkali land consolidation project at the time of project approval，The research goal is determined as: improving degraded saline-alkali land into a high-quality farmland ecosystem。Not just creating farmland，We must also build a high-quality ecosystem。In other words，It is necessary to take a path that is consistent with the actual conditions of Lubo Beach，Can gain economy again、Society、A new way of land consolidation with ecological benefits and "three wins"。This is the high requirement of the scientific outlook on development。

For this achievement,The words of Director Wang Zheng of the Shaanxi Provincial Department of Land and Resources hit the nail on the head,“The key issue of this achievement is a revolution in the past way of managing saline-alkali lands，It is also a technological innovation，Essentially speaking，It is the result of the guidance of the scientific outlook on development”。

Professor Suo Lisheng commented，“Can a new model be stabilized，Produce long-term effects，Depends on whether the model mechanism is scientific，Is it in compliance with scientific laws。The Lubotan saline-alkali land consolidation model is based on inheriting the traditional model，There have been many new breakthroughs。”

The key to saline-alkali land management is to solve the problem of salt redistribution，Previous，They are all based on drainage，In other words, treat saline water as the "enemy"，Resolutely eliminate (remove)。The new model treats saline water as a precious resource，To seek advantages and avoid disadvantages as the ultimate goal，Rearrange water and soil，That is, rationally arranging water storage ditches between unit fields,By precipitation、Receding water dissolves the salt in the soil，Bring salt to deeper areas，Evaporated through the ground、Crop Transpiration、Biological absorption, transformation, etc. self-degrade within the area，Part of the harmful salt is converted into organic fertilizer。As time goes by，Soil、Water

The salt content in the system gradually decreases，Aquatic、The variety of terrestrial animals and plants is gradually enriched，Showing a lot of vitality，Biodiversity and ecosystem stability are gradually achieved due to the support of networked water bodies。With the formation of forest belt and forest network、Improvement of ecological environment,There is less and less salt accumulated in the cultivation layer，Even in the salt return season，If irrigated properly，Accumulated salt will not affect crop growth。

Lubotan “coexistence of water and land，The new model of saline-alkali land consolidation of "harmonious ecology" is not just an adjustment in the application of technology，It is also conceptual innovation and progress。Saline-alkali land is widely distributed in our country，The composition and hydrogeographic conditions are different，The specific operation method of the Lubotan project cannot be a universal panacea。However，The scientific concepts it reveals，Worth investing in saline-alkali land management、Joined in land consolidation、Even all those who are concerned about China’s sustainable development issues should pay attention，To think。

Ten years of sharpening a sword，The Lubotan land consolidation project transforms saline-alkali land that has been stubborn for hundreds of years dafabet mobile logininto fertile farmland。Estimated，A total of more than 10,200 acres of cultivated land have been added in the Lubotan project area、More than 600 acres of water surface，

The quality and facilities of about 2,000 acres of cultivated land in surrounding villages have been comprehensively improved，The average grain yield per mu increased from 55 kilograms in 2000 to 400 kilograms in 2007，The annual total economic income increased from 23 in 2000.160,000 yuan jumped to 461 in 2007.660,000 yuan。Adopt new model，The actual direct investment in newly added cultivated land in Lubotan treatment is about 4,200 yuan per mu，Is half of the national land development and consolidation quota for the same period。As of the end of 2007，The investment cost has been fully recovered。

Data display，There are 370,000 acres of salt-alkali shoals like Lubo Beach in Shaanxi，The area of ​​saline-alkali land in my country is about 5.200 million acres，About 14.3 billion acres in the world,If the new model can be applied for promotion，Not only can it create a considerable economy、Social and ecological environmental benefits，It can also save a lot of engineering costs，Significant and far-reaching。

To this，Experts have given great hope，Academician of the Chinese Academy of Engineering、The views of Shan Lun, a professor at Northwest A&F University, are very representative: “Judging from the practical results of the past ten years，Lubotan model has withstood the test，I am optimistic about its prospects，Hope relevant departments will continue to provide support，To further improve this project。”
