摘要:
为了查清临江市地质灾害的类型及特征,掌握地质灾害的易发程度,为地质灾害防治提供依据,以地质灾害详查资料为基础,通过成因分析和分布特征研究,依据地质灾害发育程度、地形地貌、地层岩性、地质构造、人类工程活动、植被和降水7项因素划分临江市地质灾害易程度分区,同时明确了具体的分区原则。根据分区依据及原则,采用数学综合评判的半定量方法,并应用GIS技术,对临江市进行了网格剖分,然后为每一网格赋值并计算,完成了统计分区,将临江市地质灾害易发区共划分为3个地质灾害高易发区、4个地质灾害中易发区、3个地质灾害低易发区和1个地质灾害非易发区。通过分区评价,为临江市地质灾害的分区及分期防治、地质环境资源的合理保护与开发利用提供了基础依据。
Abstract:
In order to find out the types and characteristics of geological hazards, understand the susceptibility degree of it in Linjiang City, and provide the basis for the prevention of geological hazards, based on the detailed survey data of geological hazards, we determined the main basis and principle for the division of geological hazard susceptibility in Linjiang City by means of genetic analysis and distribution characteristics. The zoning is based on seven factors: the degree of development of geological hazards, landform, stratigraphic lithology, geological structure, human engineering activities, vegetation and precipitation. According to the zoning principle, we do the mesh generation for the Linjiang City by the semi-quantitative method of mathematical comprehensive evaluation and the GIS technology. Then, each mesh is assigned and calculated, and the zoning is completed. Finally, the geological hazard prone areas in Linjiang city are divided into three high-, four middle-, three low geological hazard prone areas and one non-susceptible geological hazard area. The zoning evaluation provides a basic basis for the zoning and prevention of geological hazards in stage, and the reasonable protection and exploitation of geological environment and resources in Linjiang City.
