摘要
甘肃省天水市属典型的山间河谷盆地型城市,受特殊地形地貌、地质构造、岩土性质等的控制和影响,地质环境较差,地质灾害发育且活动频繁,历史上造成了严重的经济损失和人员伤亡 天水市的主要地质灾害和环境地质问题有:滑坡、泥石流、河床淤积与洪水、水资源不足与水质污染等,严重威胁着人民生命财产安全,制约着城市发展 随着城市规模的扩大,地质灾害和环境地质问题将更加突出 通过调查研究,提出了合理利用与保护地质环境。
Tianshui is a typical mountain\|river basin 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. Based on the study and investigation of the environmental geology of Tianshui city, this article proposes the countermeasures for geological hazards control and the methods of protecting and reasonably utilizing geological environment.
