摘　　要：构建了长江流域农业可持续发展能力评价指标体系,通过熵权法确定各项指标权重,在此基础上运用TOPSIS方法进行评价,并运用Dagum基尼系数进行空间差异的测算。结果表明,浙江省、江苏省和湖南省农业可持续发展能力较优,处于一级区间;上海市、湖北省和安徽省农业可持续发展能力中等,位居二级区间;而四川省、云南省、江西省、贵州省和重庆市农业可持续发展能力则处于较差水平。由Dagum基尼系数结果可知,长江流域上游、中游、下游区域内部农业可持续发展能力较为均衡,地区差异主要源自上游、中游、下游之间的差距。因此提出加大流域农业投入、改善农业生产条件等建议,以提高农业生产效率,促进农业可持续发展及平衡地区差异。The evaluation index system of agricultural sustainable development capacity in the Yangtze River Basin was constructed,and the weight of each index was determined by the entropy weight method. On this basis,TOPSIS method was used to evaluate,and Dagum Gini coefficient was used to calculate the spatial difference. The results showed that the sustainable agricultural development ability of Zhejiang Province,Jiangsu Province and Hunan Province were better,which was in the first level. The sustainable agricultural development ability of Shanghai City,Hubei Province and Anhui Province were medium,ranking in the second level. However,the sustainable agricultural development ability of Sichuan Province,Yunnan Province,Jiangxi Province,Guizhou Province and Chongqing City were at a poor level. According to the results of Dagum Gini coefficient,the sustainable agricultural development capacity of the upper,middle and lower reaches of the Yangtze River Basin was relatively balanced,and the regional differences were mainly caused by the gap between the upper,middle and lower reaches. Therefore,suggestions such as increasing agricultural input and improving agricultural production conditions were put forward to improve agricultural production efficiency,promote agricultural sustainable development and balance regional differences.
