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.
