Study on frangibility zoning of agricultural drought in China

According to the water resources characteristics,agriculture suffering drought and forming drought disaster circum-stance and drought-relief ability of water conservancies facilities of the every locality,the principle and index of agricultural drought frangibility zoning are determined,and an analytic hierarchy process model is constructed.A frangibility zoning chart of agriculture drought is drawn in China by applying the software of Map Info6.0. The results show that there are 47 extremely serious frangible regions,104 serious ones,175 general ones,and 14 longitudinal ones,within 340 agricultural drought fran-gibility zonings of countrywide.
