以吉林省山地城市通化市为例,以区内地形地貌、岩土体类型等环境地质特征的研究为基础,分析地质灾害的发育特征、分布规律及形成条件。采用单元网格划分法进行易发性、易损性分区,对地质灾害的危险性及造成的经济损失进行评价,并提出地质灾害防治对策,为山地城市的规划建设及地质灾害防治提供了参考,对保护环境可持续发展有着重要的意义。
Taking the mountainous city of Tonghua in Jilin Province as an example, this paper analyzes the development characteristics, distribution and formation conditions of geological disasters on the basis of the research on the environmental geology characteristics such as topography, rock and soil types in the area. Adopting the method of unit cell division to carry out the vulnerability and vulnerability partition, the risk of geological disasters and the economic losses caused by them are evaluated, and the countermeasures of prevention and control of geological disasters are put forward, which provide references for the planning and construction of mountainous cities and prevention and treatment of geological disasters , Which is of great significance to the sustainable development of the environment.
