摘　　要：农业水土资源可持续利用是推进塔里木河流域生态文明建设、协调兵团向南发展战略部署以及促进各产业融合发展的重要基础。本研究基于2005-2020年塔里木河流域5个地区的农业水土资源匹配现状,运用基尼系数法、农业水土资源匹配系数以及农业水土资源当量系数,结合ArcGIS软件对塔里木河流域水土资源时空匹配状况进行分析。结果表明:从地理分布上来看,塔里木河流域耕地资源主要集中在喀什地区、阿克苏地区,耕地资源分布和水资源有密切关系。在研究时间跨度内,水土资源基尼系数在0.05~0.12之间,整体表现为波动变化,但是变化幅度不大,处于绝对均衡水平。农业水土资源匹配系数在研究期内呈现出先下降后升高再下降的特征,5个地区的农业水土资源匹配系数逐渐趋于一致,并稳定在1~2之间。结合当量系数分析,虽然塔里木河流域5个地区的农业水土资源均衡程度较好,但是5个地区仍处于极度缺水状态,且地区差异大。研究表明,塔里木河流域水土资源分布一致,整体处于缺水状态,随着节水力度的增大农用水占比呈下降趋势。The sustainable utilization of agricultural water and land resources is an important foundation for promoting the construction of ecological civilization in the Tarim River basin,coordinating the strategic deployment of the Corps to the south,and promoting the integrated development of various industries.Based on the current situation of agricultural water and land resource matching in five regions of the Tarim River basin from 2005 to 2020,the Gini coefficient method,agricultural water and land resource matching coefficient,and agricultural water and land resource equivalent coefficient were used in combination with the ArcGIS software to analyze the spatiotemporal matching status of water and land resources in the Tarim River basin.The results indicate that:the distribution of agricultural water and land resources in the Tarim River basin is uneven in various regions,but the distribution of water and land resources is relatively uniform.In the time span of the study,the Gini coefficient was between 0.05 and 0.12,and the agricultural Gini coefficient fluctuated as a whole,but the change range was not large and was at the absolute average level.During the study period,the matching coefficient of agricultural water and land resources showed the characteristics of first decreasing,increasing,and then decreasing,and the matching coefficient of agricultural water and land resources in the five regions gradually tended to become consistent and stable between 1 and 2.According to the analysis of the equivalent coefficient,although the equilibrium degree of agricultural water and land resources in the five areas of the Tarim River basin has improved,the five areas are still in a state of extreme water shortage,and regional differences are large.Research has shown that the distribution of soil and water resources in the Tarim River basin is consistent,and overall in a state of water shortage.With the greater water-saving efforts;the porpotion of agricultural water is decreasing.
