Research on the Distribution of Nitrogen and hydrochemistry Index in the Dike-Pond of the Pearl River Delta;

Hydrology,Hydrochemistry and Exploitation of Resources in Caka Salt Lake;

Studies on the Root Channels and Hydrochemistry of Reed-dominated Land/inland Water Ecotone in Baiyangdian Lake;

According to water chemistry data from 1959 to 1984 at 109 monitoring stations collected from the water yearbook edited by the Water Conservancy Ministry of China,the chemical characteristics and genesis of major ions of the Pearl River System were investigated.

With the improvement of water chemistry management of secondary system in Qinshan nuclear power plant(QNPP,) the water quality of secondary system becomes better and better.

By contrast of the composition of environment isotope and water chemistry in water,the relation between them can be determined to distinguish the replenishment resource of groundwater,the position and range of leakage,the stratum formation and and so on.

Study on hydrochemical mineralization factor of gold placer;

The distribution law of TDS and main ion concentration in groundwater with three circulating depths of shallow,middle and deep level has been studied in the Ordos Cretaceous Artesian Basin by 1124 hydrochemical samples.

The horizontal zonal characteristics of hydrochemical type in groundwater with three circulation depths of shallow,middle and deep level have been studied in the Ordos Cretaceous Artesian Basin on the basis of analyzing 1 125 hydrochemical samples.

The existence of neotectonics and its water conducting behavior and water storage capacity of Lu'an coal mine were testified by hydrogeochemistry method.

The authors have used the analyzing method of hydrogeochemistry and environmental isotopy, studied the groundwater formation process and transport regularity, and then estimated the residence time of groundwater, and summarized the groundwater forming model for Daliuta mining area.
