| 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。利用北京近1000个坡面径流试验小区的年降雨、径流和泥沙资料以及人工降雨试验资料,并考虑北京石质山区存在大量砾石覆盖地表的特点,将砾石覆盖因子作为一个独立的因子考虑在土壤流失方程中。得到北京山区坡面土壤侵蚀方程,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。 |

| Abstract: | Soil erosion is one of important factors which results in environment deterioration. Soil loss equation can be used to evaluate the dynamic development of the soil resource and develop plans for controlling soil erosion. The equation can be applied to assess the benefits of soil loss control practice. Experimental data of about 1000 annual rainfall plots in Beijing were used to develop Beijing soil loss equation. 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 soil loss dynamic monitoring in Beijing and for soil and water conservation planning. |
| Keywords: | soil loss equation soil and water conservation soil erosion Beijing |
