基于GIS与信息量模型的地质灾害危险性评价——以云南省丘北县为例
Risk assessment on the geological disasters based on GIS and information content model—Taking Qiubei County , Yunnan Province as an example
摘要
Abstract
T his paper takes the geological disasters in Qiubei County , Yunnan Province as the research object , and selects slope , fault structure , engineering geological rock group , rainfall , road , river system and land based on the combination of GIS and information model , the risk assessment of geological disasters in Qiubei County was carried out by using/indexing the seven indexes . According to the comprehensive information , Qiubei County was divided into extremely low , low , medium degree , height and very high 5 level dangerous area . The results show that the geological disasters in the study area are mainly distributed in the western and northern regions . The geological disasters are concentrated in the soft and hard interbedded and soft rock distributions , and are consistent with the distribution of terrain slope , traffic trunk and river system , and the distribution of the current disaster points has a good correlation with the risk zoning . Through field verification , the dangerous zoning and the actual situation are more consistent . The research results are consistent with the actual situation , it shows that information model combined with GIS has advantages in studying the spatial distribution and the risk assessment of geological disasters , and the research results can provide data support for Qiubei County to carry out geological disaster prevention and management .关键词
