【摘要】 水土流失是生态环境恶化的重要原因之一。土壤流失方程是定量评价水土资源发展动态、指导综合治理规划和评价水土流失治理效果的重要技术工具。本研究利用北京近1000个小区年坡面径流试验小区的降雨、径流和泥沙资料以及人工降雨试验资料,得出了北京山区坡面土壤侵蚀方程为:A=RKLSCPRF,并确定了方程中各个因子的计算方法或数值。该方程的建立,可为北京山区土壤侵蚀动态监测和水土保持规划提供依据。更多还原

【Abstract】 Soil erosion and water loss is one of important factors which result in environment deterioration. Soil loss equation can be used to evaluate the dynamic development of the water and soil resource and develop plans for controlling soil erosion. The equation can be applied to assess the soil loss control practice. Experimental Data of a-bout 1000 plots in Beijing were used to develop Beijing soil loss equation as follow: A = RKLSCPRF, The algorithm or data of every factor in the equation has been determined. The development of the equation can be used as a tool for Beijing soil and loss dynamic monitoring and for soil and water conservation planning.更多还原
