摘  要：
我国西北干旱半干旱区水资源供需矛盾日益加剧,重点区域的水资源承载力评价研究亟需开展。从城市、区域和流域的尺度,对水资源承载力的研究现状进行了总结,研究从针对于局部领域逐渐发展到对人地关系系统的综合分析;分析了水资源承载力评价方法及其适用性,从常规趋势法,到多承载因子综合评价的模糊评价法和主成分分析法,再到引进生态生产性土地进行间接评价的生态足迹法和进行整体最优化分析的多目标决策法,最后到引进计算机仿真技术动态模拟的系统动力学方法。还对西北干旱半干旱区水资源承载力的研究趋势进行了展望,认为水资源承载力的相关概念、理论和评价方法等基础研究还会持续进行,生态环境问题将会被更多地纳入研究范畴,评价方法的多元化和多技术结合将是未来研究的主要热点问题。

摘  要：
The imbalance between supply and demand of water resources in the arid and semi-arid regions of northwest China is growing increasingly severe. Consequently,it is essential to study the water resources carrying capacity in the key areas timely. The research on water resources carrying capacity in these areas is summed from three aspects,namely city,district and valley; the focus is developed from local domain to systematic research on man-land relationship. Then,the research methods of water resources carrying capacity are summarized and analyzed,including simple routine method,fuzzy evaluation,principal component analysis,ecological footprint method,multiple objective decision making method and systematic dynamics method. Moreover,the relative merits and application condition are also provided. Finally,it is presented that the research on water resources carrying capacity in future will still refer the concept,theory and research methods. Ecological environment will be put more focus on and more methods and techniques will be used.
