Characteristics of karst groundwater system at Baiquan of Xingtai City and its reasonable development and utilization;

Duality method for assessing karst groundwater vulnerability and its application in Jinfo mountain of Chongqing;

Hydrochemical study of karst groundwater in the Jinan spring catchment;

the constantly increasing mining of karst water, decreasing of precipitation, and coal mining induced water discharge.

In this paper the character istics of karst water flow are expounded and the features of karst water movement in South China and in North China are discussed respectively.

This paper focuses on karst water resource and its recharge and discharge properties in Xuzhou.

On the basis of discussion into the hydrogeological Features of Karst ground water system in Longzici spring, preliminary probe into the prospects of exploitation and application of the karst ground water.

Karst ground water is widely dispersed in China.

The paper researches intensively the effect to water environmentbeing produced by mass exploiting the karst ground water in largepower plant taking HANFENG power plant for example.

This paper introduces the general situation of Yanhe Spring Area,studies the data of the karstic groundwater level in Yanhe Spring Area,and analyzes the dynamic characteristics and influencing factors of karstic groundwater.

After the impounding of the reservoir,the karstic hydrogeological condition in the mining area has changed obviously: the first is general rising of karstic groundwater table,upswing range is declinin.
