基于“3S”技术的村镇住宅洪灾脆弱性曲线研究
Research on Flood Vulnerability Curves of Rural Dwellings Based on “3S” Technology
摘要
Abstract
Flood vulnerability curves normally relate to a set of elements at risk and present information on the relationship between flood damage rates and flood inundation parameters, and they are the essential components of the risk assessment for the flood disaster. In order to establish flood vulnerability curves of rural dwellings, taking the flood disaster of Kouqian town in Yongji county in 2010 as an example, GPS technology was used in order to collect data in the field based on sampling theory; the depth of flood water was extracted by using RS and GIS technology in order to obtain additional data; the relationship between depth and loss rate was established by using regression analysis in order to present flood vulnerability curves of rural dwellings. The result shows that: the depth of flood water and the loss rate of the rural dwelling were in high correlation, and the loss rate increased with the using time of rural dwellings. Flood vulnerability curves can provide an important basis for disaster prevention and reduction.关键词
