以石匣小流域为坡地水土流失监测试点,以遥感及地理信息系统技术为手段,以坡地径流小区定位观测为依据,建立石匣小流域坡地水土流失监测系统,定位、定性、定量监测各种坡地类型的水土流失量、污染物流失量,为水土流失监测预报提供数据,为全市山区水土流失监测预报工作提供经验及方法,为制定水土流失防治方针政策及水土流失生态环境建设提供依据。
Taking Shixia small watershed as a pilot project of monitoring soil and water loss, a monitoring system of slope soil erosion and soil erosion in Shixia small watershed was established based on the remote sensing and GIS techniques and on the basis of location and observation of slope runoff plots. Positioning, qualitative and quantitative monitoring The amount of soil and water loss and the loss of pollutants on sloping land provide data for monitoring and forecasting of soil and water loss and provide experiences and methods for monitoring and forecasting soil and water loss in mountainous areas of the whole city so as to provide basis for formulating policies and policies on soil and water loss prevention and control and soil and water loss ecological environment construction.
