Abstract：Using Remote Sensing technique and meteorological and hydrological data, the following researches are made: evaluation of waterlogging damages, estimation and calculation of production reducing rate of rice, the analysis on " July,1991" Flood in Jianghan Plain of China. Two methods can be used during remotesensing estimating crop production-reducing rate: 1) to estimate submerging area,depth, lasting time, then to estimte producting-reducing rate, this may be called as direct method ; 2) to avoid producion-reducing element, and using vegetation index as the target of evaluating damages and estimating praduction-reducing rate, this may he called as indirect method. It' S the first time to make qualitative and semiquantitative estimation of Jianghan Plain " July, 1991" Flood damages. The research result has shown that this method is relatively accurate, timely, convenient.Its result is able to provide the research basis and decision-making basis for insurance, civil administration and other government departments.
