摘要
中国政府在北方实施大范围退耕还林还草政策,使北方地区植被发生了剧烈的变化,对区域内的水文过程产生了一定的影响,该问题已经成为近年来水文与水资源研究中的科学前沿问题。文中探讨性总结了植被变化对径流、蒸散发和土壤含水量等方面影响的研究进展,并在此基础上讨论了土壤水和区域水储量变化对植被变化响应中亟待加强的科学问题和主要研究内容。
There existed large vegetation change in Northern China in last several decades since national vegetation restoration projects were implemented.The most effective one is the"Grain for Green Project",which was launched in 1999 and has had certain impacts on the hydrological processes.Investigating hydrological consequences of vegetation change is an important aspect of hydrology and water resources.This paper summarizes the research progress of vegetation change impacts on key hydrological processes,including surface runoff,actual evapotranspiration and soil moisture.It also discusses scientific issues and potential future research directions of soil moisture and regional water storage change influenced by vegetation change.
