摘要
根据各地水资源的特点、农业受旱成灾的情况及水利设施抗旱能力,确定农业干旱脆弱性分区的原则和指标,构造层次分析模型。应用MapInfo6.0软件绘制了中国农业干旱脆弱性分区图,结果表明:在全国340个农业干旱脆弱性分区中,极严重脆弱区47个,严重脆弱区104个,一般脆弱区175个,轻度脆弱区14个。
According to the water resources characteristics, agriculture suffering drought and forming drought disaster circumstance 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 MapInfo6.0. 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 frangibility zonings of countrywide.
