摘　　要：水是干旱区生态系统赖以维系的重要因子,也是制约经济发展的瓶颈所在。文中以黑河中游为研究区,基于绿洲灌区统计数据、地下水、气候、NDVI、DEM等数据构建具有空间异质性的水资源脆弱性评价指标体系,并根据评价结果进行局部空间自相关分析。结果表明:黑河中游水资源脆弱性存在明显空间差异性,大致呈由东南向西北逐渐增加的态势,局部自相关"高-高"的脆弱性高风险区主要分布在北部及西北部地区,"低-低"的低风险区则主要分布于东南部;距水系远近、地下水分布、降水、聚落分布是主要影响因子;基于水资源脆弱性的空间分异特点和形成原因,提出具针对性的适应性策略,为区域水资源规划管理提供参考。In arid areas,water is not only the most important factor in the ecological environment,but also the bottleneck restricting economic development. Based on the statistical data of oasis irrigation area,groundwater,climate,NDVI and DEM,this research constructs the evaluation index of water resources vulnerability in the middle reaches of Heihe River and execute local spatial autocorrelation. The results show that there are obvious spatial differences in the distribution of water resources vulnerability in the middle reaches of Heihe River,and the trend of vulnerability gradually increases from southeast to northwest. The local spatial autocorrelation analysis of water vulnerability indicates that the ＂High-High＂areas mainly distribute in the north region while the＂Low-Low＂areas distribute in the southeastern part. The distance to river and irrigation channel,groundwater distribution,precipitation and settlement distribution are the main factors affecting the vulnerability of water resources. According to the reason and the distribution of water resources vulnerability,we propose the relevant adaptive strategy to provide consultation of region water resources management.
