【摘要】 在应用新近建立的云南金沙江流域土壤流失方程测算该流域各县(市、区)年均土壤流失总量和各地类年均 土壤流失量基础上,分析了该流域水土流失的总体特征、各地类水土流失特征和不同坡度级坡耕地的水土流失特 征,为因地制宜地防治水土流失提供了依据。更多还原

【Abstract】 Using newly developed soil loss equation in Jinsha River Basin of Yunnan Province, the authors in the paper calculated the annual average soil loss amounts of the total land and every land use type of every county in the Basin, and analysed the characteristics of soil erosion on total land, every land type and cultivated land with different slope class in the Basin. The study revealed the main characteristics and laws of soil erosion in the Basin, and may provide scientific bases for mapping out the planning of preventing and controlling soil erosion in the light of local conditions.更多还原
