摘　　要：水资源作为人类社会生产和发展的基础性资源,其对生态文明建设的重要性日益凸显。本文基于生态足迹法和相关分析,从生态足迹、生态承载力、生态盈余、水资源利用效率以及各县市之间空间分布差异等方面对2000—2015年延边州水资源进行分析。结果表明:延边州水资源生态足迹均值为1.328 6×10~6hm^2,农业用水足迹、工业用水足迹、生产用水足迹、生活用水足迹、生态用水足迹分别为9.452×10~5hm^2、2.128×10~5hm^2、1.158×10~6hm^2、1.591×10~5hm^2、1.15×10~4hm^2,农业用水比重为71.14%;水资源生态承载力与生态盈余均呈波动下降趋势,水资源利用率逐年提高,并在2008年后水资源利用效率提高趋势趋于平缓;2015年,延边州8个县(市)水资源生态足迹、生态承载力、生态盈余、水资源利用效率空间分布不均衡,存在一定的地区差异;影响延边州水资源总生态足迹的主要因素有人均用水、农业用水、生产用水。Water resources,as a basic resource for the production and development of human society,has become increasingly important for the construction of ecological civilization. Based on the ecological footprint method and related analysis,this paper analyzes the water resources of Yanbian Prefecture from 2000 to 2015 from aspects of ecological footprint,ecological carrying capacity,ecological surplus,water use efficiency,and spatial distribution differences among counties and cities. The results show that the average ecological footprint of water resources in Yanbian is 1. 328 6 × 10~6 hm^2,and the agricultural water footprint,industrial water footprint,production water footprint,domestic water footprint,and ecological water footprint are 9. 452 × 10~5 hm^2,2. 128 × 10~5 hm^2,1.158 × 10~6 hm^2,and 1. 591 × 10~5 hm^2,1. 15 × 10~4 hm^2,the proportion of water used for agriculture is 71. 14%; the ecological carrying capacity of water resources and ecological surplus both fluctuate and declining,and the utilization rate of water resources increases year by year,and the trend of water resources utilization efficiency tends to be gentle after 2008; In the year,the spatial distribution of water resources ecological footprint,ecological carrying capacity,ecological surplus,and water use efficiency of 8 counties（ cities）in Yanbian Prefecture was uneven and there were certain regional differences; the main factors affecting the total ecological footprint of water resources in Yanbian Prefecture were Water,agricultural water,production water.
