%X 干旱是沿黄地区农业发展的长期制约性因素, 研究黄河流域典型区域的干旱等级评价方法, 建立黄河流域干 旱评价模型, 科学、客观、准确地评估黄河流域及供水区干旱级别, 是做好抗旱工作的前提和基础。采用TOPSIS 客 观赋权法对各干旱评价指标进行加权, 构建一个干旱综合指数, 对陕西省黄河流域1999 年6 月- 1999 年8 月进行 干旱综合评价, 评价结果与实际情况相符合, 证明了评价方法的合理性和可操作性。  In the Yellow River, dr ought is one of the mo st outst anding natural disasters in agr icultural pr oductio n, w hich has be2 come a long2term co nditionalit y factor of agr icultural dev elopment in the area. Develo pment of the drought g rade ev aluatio n met ho d in typical r egions of the Yellow Riv er, establishment of the ar id ev aluatio n model of the Yellow Riv er, and scientific, ob2 ject ive, and accur ate evaluatio n of the dro ug ht level in the Yellow River and w ater supply area are the premise and foundatio n of dr ought relief w or k. In this paper, TOPSIS objectiv e weig hting method w as used to assign w eights fo r each droug ht ev aluatio n index and then to dev elop a comprehensive dr ought index , w hich w as used to per form dr ought analysis in the Yellow River of Shaanx i Pr ov ince betw een June 1999 and August 1999.
