摘要
通过构建人类活动强度指标与洪涝灾害易损度指标体系,以江汉平原19个县(市)为统计单元,运用数学模型对各单元的人类活动强度及洪涝灾害易损度进行定量评估,然后利用ArcG IS对研究区人类活动强度与洪涝灾害易损度进行空间耦合分析并划分等级,结果表明:二者具有较明显的空间分异规律,且具有较高的相关性,说明江汉平原人类活动的致灾效应明显。
This paper presents an assessment of the vulnerability between human activities and flood disaster for each different unit,which based on a mathematical model that taking 19 counties(cities) in Jianghan Plain as statistical unit and built a vulnerability standard system of human activity and flood disaster.After that,an analysis and a ranking of coupling are represented for the vulnerability,which based on the ArcGIS.Finally,the results show that the spatial distribution of them differs obviously and the correlativeness is good,and this shows disaster-causing effect in Jianghan Plain is obvious.
