气候变化对中国水安全的影响研究

 全球变暖是目前最重要的环境问题之一，水是全球气候变化最直接和最重要的影响领域。全球气候变暖将加速大气环流和水文循环过程，引起水资源量及其空间分布的变化，进而可能导致水资源短缺问题更加突出、水生态环境问题进一步恶化、洪涝灾害威胁更加严重等一系列问题。本文从防洪安全、供水安全、水生态环境安全和水工程安全4个方面分别阐述气候变化对中国水安全的可能影响。

The Possible Impacts of Climate Change on Water Security in China

Global warming has become an important environmental issue, and the water resource is the most direct sector affected by climate change. Global warming will alter the spatial distribution of water resources through accelerating hydrological cycle. In further, shortage in water resources would become more obvious, aquatic environment systems would be more deteriorated, and flood threats would be aggravated as well. Possible impacts of climate change on water security are discussed in this paper from the aspects of flood-prevention, water supply, aquatic environment, and water engineering security.
