基于高分一号卫星的江西樟树市地质灾害评价
Geological Hazard Assessment of Jiangxi Zhangshu Based on GF-1
摘要
Abstract
It's important to evaluate geological hazard of Zhangshu by using GF-1 satellite for preventing geological hazard scientifically and improving the application level of domestic satellites.The images were processed by ortho rectification,image fusion and geometric correction and then the distribution of geological hazards were generated by interpretation of these images.Small watershed evaluation unit was used to evaluate geological hazard and then disaster point density,surface hydrology,tectonic fault zone,engineering activity,rock and soil type and terrain slope were choosen as the evaluation factors.AHP determined the weight of factors and weighted average method produced the comprehensive evaluation map of geological hazards.The accuracy of the result is 78%.The result shows that the zone with high degree of danger is mainly distributed in the southeast of Zhangshu,accounting for 7.82% of the total area.The zone has a venture to get a geologic hazard in 34.68% of the whole city.关键词
