Abstract:

For a long time over exploitation of groundwater cause the geological environmen issues in the piedmont clinoplain of Daqing mountain, Hohhot, such as the drainage of shallow groundwater and continuing decline of artesian water level. This paper uses data of weather, hydrological and human exploitation in urban areas to  summarize and analysis the formation mechanism of geological environment issue by both nature and human factors. The results are discussed as follows. The special aquifer structure and the changes in natural conditions provides access to possibility of geological environment issue; the increase of artesian water exploitation and reduction of piedmont lateral recharge are decisive factors; the confined water captures the piedmont lateral supplies of the phreatic water speeds up the development of geological environment issue.

Key words: geological environment, piedmont clinoplain, over exploitation of groundwater, Hohhot
