【摘要】 根据森林对水文过程的影响 ,森林水文学研究可以分为 3个相互关联的方面 :森林植被变化影响水量和水质定位试验研究 ;森林植被变化对水文循环机制的影响 ;旨在为资源管理和工程建设提供决策依据的基于物理过程分布式参数森林水文模型开发 .定位试验研究不仅可以为森林水文模型参数化提供第一手资料 ,同时也可以揭示森林植被影响径流形成机制和进行径流成份的分割 ,径流形成机制的研究则有助于改善基于物理过程模型的开发 ,模型研究反过来又可以为改进试验研究和径流形成机制研究提供指导 .本文对以上 3个方面的国内外研究进展进行了较为系统的概括 .更多还原

【Abstract】 According to the effects of forest on hydrological process, forest hydrology can be divided into three related aspects:experimental research on the effects of forest changing on hydrological process quantity and water quality; mechanism study on the effects of forest changing on hydrological cycle,and establishing and exploitating physical-based distributed forest hydrological model for resource management and engineering construction. Orientation experiment research can not only support the first-hand data for forest hydrological model, but also make clear the precipitation-runoff mechanisms. Research on runoff mechanisms can be valuable for the exploitation and improvement of physical based hydrological models. Moreover,the model can also improve the experimental and runoff mechanism researches.A review of above three aspects are summarized in this paper.更多还原
