摘要
分析了深圳市近年来历史发灾点的分布规律。选取了高程、坡度、坡向、起伏度、距离断层的距离、工程地质岩组和人类工程活动强度等影响因子,利用信息量模型分析了深圳市地质灾害易发性指数和危险性指数,开展了危险性区划研究。为地质灾害防治规划的编制提供了基础支撑。
The distribution rule of historical disaster sites in Shenzhen in recent years was analyzed. The influencing factors such as elevation, slope, slope direction, undulation, distance from fault, engineering geological rock group and intensity of human engineering activities were selected, and the susceptibility index of geological hazards in Shenzhen was analyzed using the information quantity model, and a risk zoning study was carried out. It provides basic support for the preparation of geological hazard prevention and control planning in Shenzhen.
