摘　　要：研究了人类社会对水资源的消耗、对自然生态环境的影响以及该影响的量化方法和量化指标,将生态足迹法引入区域水资源承载力系统,构建珠海市水资源生态承载力计算模型,分析计算水资源供给对区域经济社会发展的生态承载力,并对该地区的水资源生态承载力进行生态盈亏和敏感性评价。结果表明,总体上珠海市水资源系统呈现生态亏损,亏损率为37%,水资源生态承载呈现超载现象,珠海市城市化进程中流动人口增长对区域水资源的生态承载压力较大。研究结果还表明,将生态足迹模型运用到地区水资源承载力中具有较高的可信度,对地方尺度具有适用性。This paper studies the water consumption in human society that influences the natural ecological environment and the quantitative method and quantitative indicators of the influence.Introduced to the system of regional water resources carrying capacity, the ecological footprint method is used to build Zhuhai calculation model of the ecological carrying capacity of water resources, calculate and analyze the the water supply ecological carrying capacity of regional economy and social development,and assess the gains-losses and sensitivity of the region ecological carrying capacity. It is overall showed that there is a loss of water resource systems, a loss rate of 37% and water resources ecological carrying present overload in Zhuhai city.Because of the process of flowing population growth, regional water resources are carrying more pressure. Our results also show that the ecological footprint model applied to the water resources carrying capacity in the region has high credibility and applicability of the local scale

关 键 词：生态足迹 水资源承载力 敏感性
