摘　　要：为科学有效地量化流域供水效益和为流域高质量发展规划提供参考,基于能值分析理论,提出了分行业供水效益能值量化方法体系,包括水资源生态经济价值计算与供水效益计算,获取多对象分行业供水效益,在此基础上,应用MoranʹI指数和LISA指数进行空间自相关分析,解析空间供水分布规律。以黄河流域56个供水城市为研究对象,计算了黄河流域各地市工业、农业、生活和总供水效益,分析了区域间各行业供水效益的空间分布特征和关联关系。结果表明:①黄河流域分行业水资源生态经济价值在数值上表现为生活>工业>农业,空间上呈现西低东高的趋势;②黄河流域工业、农业、生活和总供水效益分别为581.29、891.63、682.66和2155.58亿元,其中,位于黄河中下游的河南省和山东省的工业供水效益较高,宁夏、内蒙古和山东省的农业供水效益在本省的各行业供水效益中较为显著;③工业、农业、生活和总供水效益的Moran′I指数分别为0.286、0.412、0.225和0.357,空间聚集性显著,“高-高”模式主要集中在中下游的河南山东段,“低-低”模式分布在上游的青海、宁夏地区,空间格局分布特征与区域经济发展水平、气候地理条件、自然资源条件、城市发展战略政策等因素相关。研究结果可为黄河流域水资源合理配置和引水结构调整提供参考。In order to scientifically and effectively quantify the water supply benefits of the basin and provide a reference for the high-quality development planning of the basin,based on energy analysis theory,this paper puts forward the quantification method system of water supply benefits in different industries,including water resources ecological economic value calculation and water supply benefits calculation so as to obtain multi-object and sub-industry water supply benefits.On this basis,the Moran′I index and LISA index are used for spatial autocorrelation analysis to analyze the distribution law of water supply in space.By taking 56 water supply cities in the Yellow River Basin as the research object,this paper calculates the industrial,agricultural,domestic and total water supply benefits of each city in the Yellow River basin,and analyzes the spatial distribution characteristics and correlation of water supply benefits of each industry in the region.The result shows that①the value of water resources in various industries in the Yellow River Basin is numerically expressed as life>industry>agriculture,and spatially presents a trend of low in the west and high in the east;②the benefits of industrial,agricultural and domestic water supply in the Yellow River basin are 58.129 billion yuan,89.163 billion yuan and 68.266 billion yuan respectively,among them,the industrial water supply benefits of Henan Province and Shandong Province,which is located in the middle and lower reaches of the Yellow River,are relatively high,and the agricultural water supply benefits of Ningxia,Inner Mongolia and Shandong Province are significantly greater than that of the other two industries in this province.③The Moran′I indices of industrial,agricultural,domestic and total water supply benefits are 0.286,0.412,0.225 and 0.357,respectively,with significant spatial clustering,the“high-high”pattern is mainly concentrated in the Shandong and Henan in the middle and lower reaches of the Yellow River,and the“low-low”pattern
