THE PROBLEMS OF ENVIRONMENTAL GEOLOGY IN TIANSHUI CITY

Due to many factors, such as special landforms and topography, geological structure, the property of rock and soil etc., the geological environment of Tianshui city is quite bad, and geological hazards develop seriously and the activity is very frequent. Huge loss of economy and life has been caused by geological hazards in the history. Landslide, debris flow, silting of riverbed, terrible floods, deficiency of water resource and contamination of water quality are the principal problems of geological hazards and environmental geology. All the hazards imperil the safety of life and property of the people, and restrict the development of Tianshui city. The geological hazards and the problems of environmental geology are more seriously coming along with the expanding city dimension.
