洪涝灾害及其衍生影响动态评估方法技术方案

本文主要介绍了洪涝灾害及其衍生影响的动态评估方法。研究首先提出了承灾体信息空间展布模型，通过网络大数据、模型构建等方法，对人口、GDP数据进行空间化分析，并以巢湖流域为例展示了结果。接着，提出了洪涝灾害直接损失动态评估方法，构建了洪涝灾害损失评估指标体系，并创新性提出混沌粒子群遗传算...This paper mainly introduces the dynamic assessment method for flood disasters and their derived impacts. Firstly, this study proposes the spatial distribution model of hazard-bearing body information, conducts spatialization analysis on population and GDP data through methods such as network big data and model construction, and takes the Chaohu Lake Basin as a case study to demonstrate the results. Subsequently, it proposes the dynamic assessment method for direct losses of flood disasters, constructs the index system for flood disaster loss assessment, and innovatively puts forward the chaotic particle swarm genetic algorithm...
