October 6-7, 2008，Scientific and technological achievements appraisal meeting hosted by the Shaanxi Provincial Department of Science and Technology，The results of "Research and Practice dafabet loginon the Harmonious Ecological Model for Comprehensive Management of Saline-alkali Land in Lubotan, Shaanxi Province" passed the expert appraisal。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 stated that “the results have generally reached the international advanced level of similar research”。

The Lubotan land consolidation project is after the implementation of the new "Land Management Law"，The first batch of land consolidation projects for off-site development of farmland occupation and compensation balance by the Ministry of Land and Resources。During the nearly ten years of project implementation，Not only added 10,200 acres of cultivated land，Improved the local ecological environment，And explore a way to "change drainage into storage" for the cleanup of saline-alkali land、Coexistence of water and land、The new model of “harmonious ecology”。

After inspecting the treatment site and listening to the report on the results，Experts from the appraisal committee spoke highly of this new model，It is agreed that this achievement governance model has a breakthrough，Innovative theoretical research，Engineering practice is effective，Control of saline-alkali land in drought and water shortage areas、Protecting the local ecological environment is of great significance。

The results are innovative in the following aspects:

One，The new model changes the core of saline-alkali land management from "discharge" to "storage"，Regard saline water as a precious resource，Based on the water level in the water storage ditch and the concentration of salt-alkali in the dafabet casino mobile appwater，Rely on small-scale microcirculation to accelerate water and salt exchange，Changing the salt distribution in the soil，Gradually push down salt to improve farmland；With the rain、Irrigation water withdrawal、Natural changes in groundwater levels, etc.，Gradually restore the ecology。

Part 2，New model reveals the mechanism of accelerated salt pressure in water storage ditches under water storage conditions in severe saline-alkali land management，Focus on the study of water storage conditions，Salt migration rules between soil-water interface。From the spatial distribution of water and land，Analyzed the ratio of water to land、Changes in water and salt content；From the time span，Analysis of annual abundance and drought、Seasonal changes within the year。For unsaturated layer，Establish a mathematical model of water and salt migration，And conduct numerical simulation analysis；For saturated layer，Conduct indoor experiments and mathematical simulations，To reveal the distribution and balance mechanism of water and salt in Lubotan area。

Part 3，The new model establishes an engineering optimization design model，Proposed the project implementation framework and measure system，In accordance with "scientific planning、Reasonable arrangement，Combined storage and discharge、Engineering Control，Coexistence of water and land、Dynamic Balance，Comprehensive Management、The concept of “harmonious ecology”，By establishing an engineering storage and discharge optimization design model，Reasonable planning and layout project；Proposed a four-in-one implementation framework of "model-engineering-measure-technology" and a measure system of "engineering-biology-agriculture"。Combining engineering measures with biological measures to achieve comprehensive management，Transforming severely saline-alkali land into normal agricultural dafabet.com mobileland through "artificial-natural" dual measures。
