Abstract: The waterlogging damage is the pit to agriculture in plain and lake region. This damage is related to the groundwater, ancient lakes, soil, land use and negative landforms, the conventional technique is adopted to the study of this damage. In this paper, we suggest a new technical method, the technique is based on DEM, to study this problem. The DEM is developed on the ECLIPSE MV/ 10000 AOS/ VS system, and the estimation model of waterlogging loss is built on the historical data of the test region in Jianghan Plain. and then, the rice waterlogging loss of test region is estimated by them.
