The Disaster-Bearing Limitation for Flood and Waterlogging Damages Based on the DEM
基于GIS／RS的洪涝灾害承灾极限遥感估算方法

For the investigation of disaster condition and loss estimation of flood and waterlogging damages using GIS and remote sensing, a new method can be used, that is, the estimation method of disaster-bearing limitation (the EMDL). The disaster-bearing limitation of flood and waterlogging damages (the DLFWD) is a way to express the regional stability, and the regional stability under the disaster condition will mainly depend on the disaster-bearing factors E{nk}, the disaster-causing factors E{kk}, and their coupling relationship E{k,nk} in human and environment system. In this paper, the principle and method of the EMDL are stated, that is, combining with the computational principle of the DLFWD based on the DEM data, and Extracting the information from the remote sensing images of flooding period and non-flooding period, the disaster condition of flooding and waterlogging damages can be estimated.
