The traditional method of treating saline-alkali land is to use high water pressure to control alkali、Drain away saline water、Create arable land,Experts say so,Almost everyone thinks this is the only correct way。But,In the practice of the Lubotan land consolidation project of Shaanxi Real Estate Development Services Corporation that the reporter has followed for ten years,This universally recognized method has been "revolutionized"。

The method adopted by the Lubotan land consolidation project to renovate saline-alkali land is soil desalination,Keep the saline water,Use saline water,Combination of engineering measures and biological means,Create a harmonious ecological environment of "water and soil symbiosis"。

Keep the saline water?dafabet mobile loginAlmost everyone thought it would be impossible to do this。Current practice proves,This is a successful way to control saline-alkali land。

The beginning of the Lubotan project,Ministry of Land and Resources、The leaders of Shaanxi Province have also visited the site for investigation and research。Everyone pay attention to it,Firstly, it is because it is the first batch of land consolidation projects for off-site development after the implementation of my country's new "Land Management Law",The second reason is that this kind of landform is a very typical type of cultivated land reserve resource in my country。One sentence,It is of great significance to complete this project。Deputy Minister Lu Xinshe of the Ministry of Land and Resources during an inspection,Provided affirmation and support for the direction of exploring new methods。This is a great encouragement to the comrades of the project department。Reporters have also visited the site several times for interviews。

Lubo Beach is located in Fuping, Shaanxi Province、The junction of Pucheng and two counties,is the location of Luyang Lake in Han Dynasty,A famous salt in history、Nitrogen production area,As far as the eye can see, there are wastelands and salt bags,There are also salt ponds and nitrate ponds,Many abandoned,Some are still in use。The local people have a saying: "It's white in winter,It’s watery in summer,The grass will not grow if you plant it,The grass will not grow if you plant it。”Lubo Beach today,The edited part,90% of the land can be cultivated as high-quality farmland,Nearly 100,000 trees have grown on the tidal flats that used to be barren of vegetation,The regional ecological environment has been greatly improved,Like spring in winter,The green of plants grows in the surrounding desolate and depressed environment,Water surface and cultivated land、Coexistence of trees。Not only that,The gathering of animals brings more vitality,There are various birds on the ground,Pheasant、Wild ducks and other perennial habitats,Swan、Gray cranes and others also use this place as their frequent "vacation place",The wild fish in the water attract many fishing enthusiasts to stay together every day。Such a good ecological environment appears in the beach area,According to the locals: It would dafabet casino mobile appbe unimaginable for several lifetimes。10,000 acres of standard high-yielding cotton fields compiled,Already included in the scope of basic farmland protection。

Can the success of one place prove the establishment of a new point of view?In 2006, the company leaders made a detailed report to the Party Committee of the Shaanxi Provincial Department of Land and Resources,The leaders of the provincial department are both happy and cautious,Instruct them to expand the pilot and further promote the trial,And requested the relevant departments in the department to fully support their pilot promotion work。So,The company has completed the third phase of land consolidation in Lubotan、Continue testing in the fourth phase of the project,And move this governance model to the Yanchiwa land consolidation project in Dali County。Ten years,Shaanxi Real Estate Development Services Corporation used this method to carry out five land consolidation projects on salt-alkali flats,Create high-quality farmland 1.Over 70,000 acres,Everyone was successful without exception。

The success of this new model of saline-alkali land management is a revolutionary progress,Shaanxi Province has about 370,000 acres of such salt-alkali flats,Our country has approximately 5.200 million acres of saline-alkali land,There are about 14.3 billion acres of saline-alkali land in the world,To organize in this way,Not only can it create a considerable economy、Social and ecological environmental benefits,It can also save a lot of engineering costs。

The experience gained through ten years of practical exploration and ups and downs can be summarized as: adaptive and dynamic adjustment of water and soil resource distribution,Correctly utilize the laws of water and salt migration on a microscopic level,Does not drain water outside the area from a macro perspective,Dynamic balance of coexistence of water and soil in the region,Adapt to natural changes and reduce human intervention,Relying on harmonious changes in the regional environment,Gradually realize self-repair。These ideas in the new model,Provides an important ideological line for future saline-alkali land management and regional ecological restoration。

my country’s famous water conservancy expert、National People’s Congress Standing Committee、Deputy Chairman of the Agriculture and Rural Work Committee、Professor Suo Lisheng, former Vice dafabet.com mobileMinister of the Ministry of Water Resources, said after learning about the project: This model is good、New view,Hope to summarize it to a theoretical level,Turn practical results into scientific and technological progress。Li Peicheng, an academician of the Chinese Academy of Engineering, is very familiar with Lubo Beach,He said: The ecological environment of Luobo Beach is very bad,I have been there many times before,Want to transform it,Your ten years of practice in transforming governance,Not only improves the ecology,Changed appearance,Also created new models and achieved success,It’s a great thing。This is science,I hope you can further summarize the mechanism,Promote to a wider range。

Shaanxi Real Estate Development Services Corporation has jointly carried out a large number of indoor projects with Xi'an University of Technology、Outdoor Observations and Experiments,At the same time, relevant mechanisms were also studied in a targeted manner。Currently,Summary of theoretical and practical results。
