| 摘 要： | 气候变化对水资源的影响主要表现在两个方面:①对水资源供给能力的影响;②对水资源需求性的影响。气候变化下水资源脆弱性评估是水资源系统的综合评估,主要包括水资源供给与需求平衡的评估。我国水资源深受气候影响,表现在地区分布不均、洪涝灾害严重、供需矛盾突出等方面;此外,自气候变化引起关注以来,我国有关水资源脆弱性评估的研究甚少。对水资源脆弱性评估方法进行探讨,旨在为进一步探讨气候变化下我国水资源的脆弱性提供依据。

| Abstract: | Global climate change has been extensively concerned by scientists, policy makers and the public, and become an important area of investigation in the social and natural sciences and engineering. Global climate change may have major impacts on aquatic ecosystems. The major impacts on water resources are the supply of water resources and the demand of water resources. The vulnerability assessment of water resources is comprehensive analysis of water resources ecosystem, including the supply and demand of water resources. Water resources in our country are deeply affected by climatic change, for example, the disequilibrium of distribution, the floods as well as the droughts. In addition, since the concerns with the global climate change were given, water resources vulnerability in respond to climatic change in our country has been or is being studied scarcely. Based on the reasons above, the assessment method of vulnerability of water resources under global climate change is probed in this paper, which aims at providing the scientific theoretic basis and foundation for the decision making of policy makers and the improvement of theory of vulnerability in our country. |
