摘　　要：指出了森林水文循环是森林联系气候对森林生态系统产生时空变化影响的重要因子。森林水文过程的研究以流域尺度为大多学者研究所接受,但如何正确地描述或者评价森林生态水文过程对于准确理解流域生态系统水循环及其对全球气候变化响应机制是其基础性关键。基于此,总结归纳了前人成果,以流域尺度森林水文过程的几个关键过程(林冠截留、蒸散、土壤蓄渗及径流)为基点,梳理了4个过程的衡量理论及方法,并提出了建立模型、水文过程的参数修正、结合GIS等技术进行流域尺度的模拟以及结合氢氧同位素技术对森林水文过程的溯源刻画将是正确理解森林流域水文过程机制的发展趋势,但现今仍存在如何将流域尺度外推于区域尺度乃至全球尺度这一科学问题。Forest hydrological cycle is an important factor affecting the spatiotemporal change of forest ecosystem caused by forest associated climate.The study of forest hydrological process is accepted by most scholars at watershed scale.However,how to describe or evaluate the forest eco-hydrological process correctly is the basic key to accurately understand the water cycle of watershed ecosystem and its response mechanism to global climate change.This paper summarizes the previous results,and takes several key processes(canopy interception,evapotranspiration,soil storage and infiltration and runoff)of watershed scale forest hydrological processes as the basis.The measurement theories and methods of the four processes are summarized.It also looks forward to the parameter modification of the model or hydrological process,the watershed scale simulation by GIS and the tracing description of forest hydrological process combined with hydrogen and oxygen isotope technology.It will be a correct understanding of the development trend of hydrological process mechanism in forest basins.It also points out that there is a scientific problem of how to extrapolate basin scale to regional scale and even global scale.
