基于GIS的流域洪涝数字模拟和灾情损失评估的研究

Study on Digital Simulating Flood-Waterlog and Evaluating Damage Based on GIS

非工程防洪措施是减缓洪涝灾害损失的有效方法之一。地理信息系统和遥感技术使多学科综合性的非工程防洪措施成为现实。本文从流域数据库设计、洪水预警数字模拟、河道洪水演进数字模拟、洪泛区洪水演进数字模拟、灾民疏散模型和洪水灾情损失评估等６个方面，系统阐述了地理信息系统在流域洪涝数字模拟和灾情损失评估上的应用，为今后开展同类工作提供了参考。

Geographic information System (GIS) and remote sensing make it practicable for nonstructural measures, multidisciplinary, which is one of the effective methods for reducing damage caused by flood and waterlog disaster. The authors make a systemtic exposition of application of GIS in digital simulating flood-waterlog harzard and evaluating the loss within river basin from disigning of basin database, numeral simulating flood harzard forecasting and flood routing in river course and floodplain, modeling victims dispersion, etc. It provides a basic framework for developing similar research in the future.
