我国水源林水文生态功能研究进展

Research Progress of Hydrologic and Ecological Function of Water Conservation Forest in China

水源涵养林是一种具有特殊意义的防护林种,也称为水源林。它具有涵养水源、改善水文状况、调洪削峰、调节区域水分循环、防止土壤侵蚀和净化水质的功能。现代社会的发展造成水资源需求量的不断增加与水环境的严重恶化,水资源质量性短缺成为全球性关注的问题。同时,我国水资源短缺的问题也是日趋严重,因此,加强水源涵养林建设是实现水资源可持续利用的有效途径。对此,从研究方法、树种选择及水源涵养机理和功能等方面,对我国水源林水文生态功能研究现状进行系统阐述。

Water conservation forest is a special kind of protection forests. It can conserve water sources, improve hydrologic situation, control flood and peak, regulate regional water circulation, control soil erosion and purify water quality. The development of modern society has caused the increasing demand of water resources and serious deterioration of water environment. Water quality shortage has become a global concern. Meanwhile, the problem of shortage of water resources in China is also growing. Therefore, strengthening the construction of water conservation forest is an effective way to achieve sustainable use of water resources. This paper systematically reviews the present research status of hydrologic and ecological function of water conservation forest in china regarding research methods, tree species selection and the mechanism and function of water conservation.
