森林生态系统水源涵养功能研究进展与展望

Research on water conservation function of forest ecosystem:Progress and prospect

森林的水源涵养功能是森林生态系统服务功能的重要方面,一直受到社会广泛关注。经过半个多世纪的发展,我国在认知森林的水源涵养功能及其机制、开展水源涵养功能的价值评估、服务水源涵养林的建设与管理等方面取得了一定进展。然而,在森林生态系统水源涵养功能的内涵边界、过程机制等关键层面上尚未形成统一的认知,严重限制了该领域有关研究成果的实践应用。为此,本文在综述森林生态系统水源涵养功能研究现状的基础上,审视与解析森林水源涵养功能的概念内涵、形成过程与综合特征,并基于该领域研究进展提出未来应加强的研究方面,以期服务于森林生态系统服务功能评估以及生态公益林管理等。

Water conservation function of forest ecosystem is an important aspect of forest ecosystem service function,which has received wide attention from the society.After the development for more than half a century,China has made some progress in understanding the function and mechanism of water conservation in forests,developing the value evaluation of water conservation function,and serving the construction and management of water conservation forests.However,there are still controversies in interpreting the connotation of forest water conservation function and the underlying mechanism,which severely limits the practical application of relevant research results.After summarizing current research status,we expounded the basic connotation,the process mechanism and the comprehensive characteristics of forest water conservation function.We proposed research aspects in the future,which would serve the evaluation of forest ecosystem service and the management of ecological public welfare forests.
