山洪灾害风险空间分异性评估及其驱动力研究
Study on Spatial Differentiation Assessment and Driving Force of Flash Flood Disaster Risk
摘要
Abstract
It is of practical significance for flood risk prevention and response to carry out mountain flood risk assessment and its driving force analysis.Therefore,this paper took Shanxi Province with frequent floods as an example,used the analytic hierarchy process to effectively i-dentify the flood risk level and its spatial differentiation characteristics,and used the global and local Moran's indexes to explore its spatial aggregation(discrete)location and distribution law.Finally,the driving mechanism behind the flood risk was explored by using the geo-graphic detector technology.The results show that the annual maximum 24-hour rainfall,multi-year average rainfall and NDVI factors are im-portant factors causing flood differentiation,and their explanatory power q values are as high as 0.57,0.52 and 0.24,respectively.The multi-risk two-factor interaction has a significant impact on flood risk,and it is enhanced or non-linearly enhanced,especially the interaction be-tween rainfall and slope factors,with a q value of 0.71.关键词
