Study on the assessment of flood disaster on summer maize based on GIS and RS technology

The endurance of summer maize to flood and the impacts of the flood on maize yields and its components were studied in this paper. Obtain maize model for quantitative assessment of flood disasters. Based on the GIS and EOS/MODIS water monitoring data, access to the flood disaster loss model can be rapid quantitative assessment. The results showed that flood had obvious impacts on the maize density, maize greenery, ear lengthen and thick, and the yields. The method can be used for fast, accurate, continuous, dynamic monitoring and evaluation of flood hazards, for the development of post-disaster planning.
