中国森林水文学研究进展(英文)

Forest hydrology research in China

森林水文学研究对于了解流域物理、生物及化学过程以及实施流域管理 ,具有重要意义。森林与水的关系及其在流域管理中的应用 ,是国际水文学及流域管理学界十分关注的课题之一。由于缺乏长期的森林水文观测数据 ,导致中国的学者们以及政府决策者之间 ,关于森林对洪水、流域年产水量以及土壤侵蚀的作用看法不一致。作者介绍了近 2 0年来中国森林水文学的发展历史 ,以及我国森林生态长期定位观测站 ,在林冠截留、地被物截留、林地蒸发散、地表径流、土壤侵蚀等方面的观测成果。此外 。

Research on forest hydrology is the key to understand the physical, biological, and chemical processes in a watershed and has significance to watershed management. Forest water relations and their implications in watershed management, therefore, are one of the key themes of international hydrology and watershed management research. Lacking of long term research data causes vigorous debates over the practical role of forests or reforestation in reducing flood, annual water yield and soil erosion in China among scientists as well as decision makers. This paper presents the historical development of forest hydrology research in China during past several decades, the long term forest ecological research stations, and major results of forest hydrological research in terms of forest canopy interception, forest floor interception, evapotranspiration, runoff, soil erosion. In addition, the future challenges of long-term forest hydrological and ecological studies that are crucial to clarify the forest impacts on hydrological regime under different geographic and forest conditions are also outlined in the context of Chinese national reforestation programs.
