摘要
随着人口的增加和经济的快速发展,人类对河流的过度开发破坏了河流的生态过程,导致河流严重污染、水量大幅减少,河流的生态系统服务功能严重退化,制约了社会的可持续发展。通过论述关于河流生态系统服务功能的研究进展,包括分类方法、价值评估方法,并从气候变化和人类活动两方面深入分析影响河流生态系统服务功能的驱动因素,提出今后应以下几方面加强研究:①河流生态系统服务功能的认识;②河流生态系统结构和生态过程的认识,③河流生态系统服务功能的时空异质性;④人类活动和社会发展与河流生态系统服务功能之间的相互影响。
Rivers,the important origin for human beings to live and develop,create indispensible conditions in social,economic and cultural aspects and provide various ecosystem services in terms of environment and resources,which plays a vital regulation and amelioration role for global ecosystem.However,with the increase of population and fast development of economics,the ec-ological processes of rivers are damaged by human overexploitation,which results in severe pollution of rivers,sharp reduction of water quantity,and the serious deterioration of river ecosystem service functions.All of them restrict the social sustainable development.This paper mainly discusses the related research progress on river ecosystem service functions,including the clas-sification methods,assessment methods and the driving factors in terms of climatic change and human activities.And then the the future research orientation should be focus on 1)natural property of river ecosystem;2)structure of river ecosystem and the understanding of ecological process;3)the spatial and temporal heterogeneity;4)the mutual influence between human and so-cial development and river ecosystem service functions.
