摘　　要：以金沙江干流中段上已建的大型水电站为例,研究了大型水电站工程建设期内不同施工区的水土流失特征。结果表明:项目区降雨量年内分配差异较大,年际间分配也不均,且降雨量过分集中在汛期;不同施工区的水土流失特征及变化趋势与汛期降雨量及降雨强度关系密切。Taking the completed large hydropower station in the middle section of the main stream of Jinsha River as an example,the water and soil loss features of various construction zones within construction period were investigated.Results show that the distribution of rainfall in the project area varies greatly during the year and between years,and rainfall is too concentrated in flood season.The water and soil loss features and variation trend are closely related to the rainfall and intensity in flood season.
