摘　　要：利用生态足迹理论计算分析了江苏省2008—2017年的水资源生态足迹、水资源生态承载力和生态盈亏状况,并根据细分的三级账户分析了出现生态赤字的主要原因,采用人均水资源生态盈亏指数、水资源生态压力指数、水资源可持续利用指数和万元GDP水资源生态足迹4个指标对江苏省水资源利用效率进行评价。结果显示:在研究时段内,江苏省水资源利用处于生态赤字的极不安全状态,但可持续利用程度整体在提升;第一产业水资源生态足迹最大,工业用水次之,两者占水资源生态足迹比例约为90%,是造成水资源生态赤字和水资源生态压力指数较高的重要原因。Based on the ecological footprint theory,the ecological footprint,ecological carrying capacity and ecological surplus and deficit of water resources in Jiangsu Province from 2008 to 2017 are calculated and analyzed.The main causes of ecological deficit are analyzed according to the tertiary accounts.The utilization efficiency of water resources in Jiangsu Province is evaluated by using the four indices of ecological surplus and deficit index of water resources per capita,ecological pressure index of water resources,sustainable utilization index of water resources and ecological footprint of water resources of ten thousand Yuan GDP.The results show that the utilization of water resources in Jiangsu Province has been in a state of extremely unsafe ecological deficit during the research period,but the degree of sustainable utilization is improving.The ecological footprint of water resources of the first industry is the largest,and the second is industry,and the sum of the above two accounts for about 90%of the total ecological footprint,which are the main reason that causes the ecological deficit of water resources and the high ecological pressure index of water resources.

关 键 词：生态足迹理论 生态承载力 生态盈亏 可持续利用 江苏省
