Days ago，Yuan Chunqing, Governor of Shaanxi Province, presided over the provincial government executive meeting，Reviewed and approved the "Shaanxi Provincial Science and Technology Award Measures" and the dafabet.com mobile2009 Shaanxi Provincial Science and Technology Award Selection Results。The "Research and Practice on the Harmonious Ecological Model for Comprehensive Management of Saline-alkali Land in Lubotan, Shaanxi Province", a project jointly completed by Shaanxi Real Estate Development Services Corporation and Xi'an University of Technology, won the first prize，Created the first land and resources system in Shaanxi Province。

It is reported，The Lubotan Salt-alkali Land Comprehensive Management Project is the first land consolidation pilot project in Shaanxi Province，From planning and construction、Theory proposed、Experimental analysis、The results appraisal took 10 years。This achievement is aimed at the large amount of projects existing in the traditional "discharge-based" governance model、A lot of space、Not conducive to water conservation、Contamination downstream and other issues，Proposed “changing discharge into storage、Coexistence of water and land、New model of comprehensive management of "harmonious ecology"。The main innovation point is: for the first time, the core of saline-alkali land management is changed from "drainage" to "accumulation"，Adopt the "artificial-natural" binary model to transform severely saline-alkali land into high-yield and stable-yield farmland；Established a "storage-based" engineering design system，Proposed a comprehensive agricultural measure system based on "engineering-biology-agriculture"；By studying the salt transport between water bodies and adjacent soil，Proposed a cyclic salt pressure mechanism for vertical distribution of soil salt；The study found that there is a transition layer of 10 to 20 cm between the unsaturated layer and the saturated layer of the soil that can effectively suppress the return of salt。

Proposition of this model，dafabet loginBreaking the traditional governance method，Provides a new theoretical basis for the management of saline-alkali lands，Appraisal by Shaanxi Provincial Department of Science and Technology，Generally reaching the international advanced level。The results were successively achieved in Fuping, Shaanxi、Dali and other places are promoted，A total of more than 18,900 acres of severely saline-alkali land has been transformed，16,500 acres of new cultivated land，Achieved significant economy、Social and ecological benefits。The promotion of technology can save hundreds of billions of dollars in the treatment of severe saline-alkali land and the replenishment of cultivated land for construction in Shaanxi Province and even the country，At the same time, in order to achieve a balance between farmland occupation and compensation、Promote the urbanization process、Making significant contributions to building a harmonious society。

The Lubotan Salt-alkali Land Comprehensive Management Project won the first prize of Shaanxi Provincial Science and Technology Award in 2009，This is a great joy for the land and resources system，Show people the great power of technological innovation。

Saline-alkali land management has long been a global problem。Although there are successful precedents，However, the commonly used "discharge"-based governance model may not be suitable for the specific conditions of Lubotan。Shaanxi Real Estate Development Services Corporation joins forces with Xi'an University of Technology，Take product、Study、New mechanism combining research，Finding strength from technological innovation，Proposed a new comprehensive management model that changes "discharge" to "accumulation"，Successfully found a new way to manage saline-alkali land in inland arid and semi-arid areas，Significant。
