基于GIS分析的鲁中南低山丘陵区地质灾害风险评价
Geological Hazard Risk Assessment of Low Mountain and Hilly Areas of Central and Southern Shandong Province Based on GIS
摘要
Abstract
In order to better carry out comprehensive prevention and control of geological hazards in low mountain and hilly areas of central and southern Shandong province,a regional geological hazard suscepti-bility and risk assessment system has been put forward based on geological hazard risk survey,information quantity model and GIS analysis.8 different evaluation indicators has selected,such as terrain slope and undulation,and the susceptibility classification and distribution range of geological hazards has been ob-tained.By overlaying the precipitation intensity obtained from Pearson's three type hydrological model at different return periods in the study area,hazard assessment has been carried out.The combination of dan-ger and vulnerability results in a risk assessment will provide a scientific basis for the prevention and con-trol of geological disasters in the study area.It is showed that as precipitation increasing,the probability of geological disasters occurring will increase.关键词
