Some problems of ecological environmental geology in arid and semiarid areas of China

Arid and semiarid areas are widely distributed in China but rich in natural resources. Because of the arid climate, complex geological conditions, and human activities, some problems of ecological environmental geology occur, such as lack of water resources, desertification, salinization, and biogeochemical endemic diseases, etc. These problems occur in fragile regions of the environment, seriously restricting the developing of the national economy and causing harm to human health. Ecological environmental geology is a new developing science in China. Through the research of ecological environmental geology and with the help of research results of the western plain of the Tarim Basin in Xingjing, we propose a comprehensive administrative measure of ecological geological environment on the basis of rational utilization of water resources, and it can be used to improve the ecological environment of arid and semiarid areas.
