Compared with others,the soft soil in Lianyungang contains high salinity,and the most ions are Cl~-,SO~(2-)_4 and Mg~(2+).

By coagulation and deposition-hydrolysis acidification-biological contact oxidation-second coagulation and deposition-biological aerated filter process to treat high salinity fur wastewater,the operation results show that,the total removal of CODCr and ammonia nitrogen reached to 94% and 87%.

Spatial variability analysis of soil salinity for Binhai Plain;

Coupling relationship between the average coverage of wetland plant communities and soil salinity in Dunhuang Xihu Wetland of Gansu Province

Through experimental research on the relations among soil salinity,soil moisture,effect of salt stress on growth of c.

The soil salt content around root layer is liable to improve the herbage quality and also promote synthetic compositions of crude protein,crude fat,crude ashes together with calcium and phosphorus contents as well as to restrain too much synthetic compositions of crude fibers.

It is helpful for drainage system design and groundwater management to decide the relation between groundwater depth and mineralization degree and soil salt content.

According to the principle of mass conservation,water and salt balance models for aeration zones and aquifers were established and employed to simulate the variation of soil salt content,groundwater depth and mineralization in the irrigation areas of each canal in the Yinbei irrigation district of Ningxia.
