Shaanxi Province is located in the center of China’s geographical territory,Through north and south,Connecting things,Also known as the land of Sanqin,Ancient civilization has a long history。

Today,This is still the bridgehead of reform and opening up in western China,Is becoming a rising pearl in the New Silk Road Economic Belt。

However,The situation of land resources, which carry Shaanxi’s economic and social development and food security, is not optimistic。In response to this situation,Shaanxi Provincial Land and Resources System increases scientific research and innovation,Support land transformation projects,To solve the balance of farmland occupation and compensation、Continuous efforts to ensure land for economic and social development...

More people, less land,Construction land increases year by year,Lack of supplementary farmland resources

According to data from the Shaanxi Provincial Land and Resources Bulletin in 2013,End of 2013,Shaanxi Province’s cultivated land area is 59.88 million acres。High-quality cultivated land resources account for about 1/4 of the province’s total cultivated land area,Mainly concentrated in Guanzhong area。

Year,The total population of Shaanxi Province is nearly 38 million,The per capita arable land is only 1.57 acres。

Since the “Eleventh Five-Year Plan”,Shaanxi’s economic development has entered the fast lane of rapid growth,Construction land increases year by year,A total of 38 construction lands were approved in the province in 2013.620,000 acres,40% year-on-year increase;In the same period, only 24 new cultivated lands were added through land consolidation.80,000 acres。

Construction land increases year by year,The amount of cultivated land is declining year by year,The sharp contradiction between land supply and demand。

The lack of supplementary cultivated land is due dafabet casino mobile appto the lack of reserve cultivated land resources in Shaanxi。Southern Shaanxi is mainly a mountainous area,Land resources that can be used as farmland are extremely scarce;Can be used in Guanzhong area、The land resources that are easy to develop were exhausted as early as 2000;Northern Shaanxi is mainly the Loess Plateau,is the main implementation area of ​​the national conversion of farmland to forest program。

Under such conditions,How to ensure that Shaanxi’s cultivated land adheres to the red line of 59.21 million acres by the end of the “Twelfth Five-Year Plan”,It can also ensure the land demand for major central and provincial projects;How to ensure food security in Shaanxi,It can also ensure the sustainable development of regional economy and society,Becomes a difficult problem facing the Shaanxi Provincial Land and Resources Management Department。

Land science and technology innovation, a weapon to solve development problems

Shaanxi has more people and less land,There are few available reserve resources for cultivated land。If a large number of existing but difficult to utilize can be used through technological innovation、Saline-alkali land that is difficult to develop、Sand Wasteland、Conversion of barren rocky beaches and other areas into cultivated land,It will undoubtedly open another door to land development space。

Back in 1999,Land researchers began to conduct land transformation experiments in the severely saline-alkali land Lubotan in Weinan, Shaanxi。Researchers explore through science and technology,Innovation proposes “changing discharge into storage、Coexistence of water and land、Harmonious Ecology” severe saline-alkali land management model,Turn thousands of acres of barren land into fertile farmland。

Data display,Shaanxi Province has 370,000 acres of saline-alkali land,The area of ​​saline-alkali land in the country is as many as 5.200 million acres。"Change discharge into storage、Coexistence of water and land、Harmonious Ecology” severe saline-alkali land management model,Created a new idea for the transformation and utilization of saline-alkali land in my country,Breaking the traditional concept of "land without technology" in people's traditional consciousness,The subsequent successful management of the Mu Us Desert completely overturned the saying that "land has no technology"。

Dajihan Village, Xiaojihan Township, Yuyang District, Yulin City, Shaanxi Province is located on the edge of the Mu Us Desert,The land here is seriously desertified,Poor ecology。To help farmers here develop towards modern agriculture,The Shaanxi Provincial Department of Land and Resources organized relevant scientific researchers to conduct research on land transformation here。

Sandy soil generally contains two components,One is arsenic sandstone,One is sand。The arsenic sandstone is exposed, weathered and dusted by the wind,Loss of large amounts when exposed to water,Called environmental cancer。Sand has loose structure,Cannot form soil aggregate structure,is the main culprit leading to the ecological degradation of soil resources。These two substances,One retains water and the other leaks,One is rigid and the other is breathable,Complementary。Scientific researchers have conducted repeated studies,Successfully matched dafabet casino mobile appthe two substances,Invented the “technology of compounding arsenic sandstone and sand to form soil, fix sand, and create fields”。

"Use this technology,From 2010 to now,We have turned more than 200,000 acres of sandy wasteland on the edge of the Mu Us Desert in the Yulin region of northern Shaanxi into fertile farmland,Strongly supports the land demand for major construction projects in Shaanxi Province。On the transformed farmland,The local government vigorously develops modern agriculture,Carry out large-scale operations、Mechanized farming,Achieved a major transformation in agricultural production methods。”Director of Shaanxi Provincial Department of Land and ResourcesWang WeiHua said.

According to statistics,After the completion of the core technology demonstration project of arsenic sandstone and sand composite soil formation in Mu Us Sandy Land,The potato yield per mu in Dajihan Village has now reached an average of 6,000 kilograms,The average corn yield per mu exceeds 1,600 jins;Potato yield per mu in Chaheze Village reaches 8,000 kilograms,Corn yield exceeds 2,000 kilograms per mu。

“Technology of compounding arsenic sandstone and sand to form soil, fix sand, and create fields”,Let the desert become fertile land,Created the miracle of my country’s land transformation project,Exploring a new path in desert ecological management,Known as the “Desert Miracle Works”。Promotion and utilization of this achievement,Making the ecological improvement of 5.3 million acres of sandy land in Yulin and the resource utilization of arsenic sandstone possible。
