洪涝灾害危险性评估方法研究
Study on the Flood Hazard Assessment Method
摘要
Abstract
In this paper,the flood hazard assessment method based on GIS spatial analysis,analytic hierarchy process (AHP) and normalization technique is used to evaluate the hazard of Songhuajiang River Basin.Through the introduction of flood disaster early soil moisture and the next 24 hours rain prediction data as the disaster factors,combined with the river network,terrain and land use types of disaster factors,determine the weight of evaluation index,applied to the flood hazard assessment.The flood disaster in mid August 2013 Songhuajiang River Basin as an example,through the comparison of using soil moisture and 3d before rainfall data of two different factors of risk assessment,and monitoring results of flood disaster meteorological satellite to verify the assessment result of risk,illustrating the obtained results coincide well with the actual situation.关键词
