东江清水河流域降水与土地利用变化对径流的影响

以东江流域（1960--2000年）降雨量及岳城站水文资料为基础，重点研究东江主要支流新丰江上游清水河流域降雨与径流的变化特征，利用降雨一径流关系，定量分析了土地利用对径流演变的作用，发现该流域降雨与径流具有很好的相关性，而土地利用是造成年径流减少的主要原因．并据此进一步分析了洪水对下垫面变化的响应．

Effect on Runoff of Precipitation and Land Use Change in the Qingshui River Attachment

Land Use/Land Cover Change(LUCC)and Biospheric Aspects of the Hydrological Cycle(BAHC)are tow core projects of the International Geosphere-Biosphere Program(IGBP).In recent decades,hydrological effect and flood response to river basin LUCC have both caused increasing concern.In this paper,the writer has put more efforts into the variation characteristics study on precipitation and runoff in the Qingshui river attachment(a small attachment in the west of the Dongjiang River Basin,Guangdong Province).By utili...
