气候变化对水质与水生态的潜在影响已经成为当前必须面对的新问题和新挑战,这也引起了世界各国科学家和政府的高度关注.但是,由于它的复杂性和不确定性,目前针对该问题的科学研究和科学实践仍然十分有限.本文首先回顾了近年来国内外相关研究成果,并指出了研究现状与现实需要之间的差距.另外,基于作者在淮河和汉江的相关研究成果,我们认为,人类活动和经济发展所产生的排污是造成水质与水生态恶化的最重要的原因,同时,气候变化在此基础上具有推波助澜的增益作用,气候变化主要通过改变水温和水文情势进而影响水质和水生态.本文最后讨论了适应性对策的内涵,认为适应性对策应该包括适应方式和适应能力建设两个主要方面,适应性对策应该尽可能地具有针对性和可操作性.本文对今后的相关研究可起澄清概念和指明方向的作用.

Potential impacts of climate change on water quality and ecosystem, as a newly emerged problem and challenge, is of great concern by scientists and governments. However, scientific researches and practices are still facing big challenges in these issues because of their complexity and uncertainty. This paper reviews the most recent literatures on this topic at first, and proposes some research gaps between published results and what needs to be known in practice. Additionally, basing on our knowledge and results of some recent case studies of the two representative rivers which are Huai River and Hanjiang River in China, it should be addressed that if the impact of climate change on the water quality and ecosystem has been taken concern, water pollution and related water environmental problem caused by human activities and economic development must be addressed firstly. It has also been recognized that water quality and ecosystem can be significantly impacted by climate change under the condition of human activities. Climate change can alter water temperature and hydrological regimes and thus influence the water quality and ecosystem. Then, the contents and principles of adaptation options and adaptability construction are discussed. The present study is expected to make clear of conceptions and to give directions for further relevant researches.
