摘要
使用美国通用流失方程（ＵＳＬＥ）并用彩红外遥感航片对其参数进行率定，计算出邛海流域６个自然集水区域的高地潜在侵蚀量。并用０．２８的输沙系数计算出年流入湖中的泥沙为１２７．４万ｔ，同时也计算了氮、磷的入湖量。文中还讨论ＵＳＬＥ模型在邛海流域的适用性。
Using the Universal Soil Loss Equation( USLE)and Calibrating Model Parameter by colour infrared remote sensing Upland Potential Erosion wascalculated from six natural catchment area in Qionghai Lake.Using 0.28 of delive-ry ration,127.4 × 104t sedimemt into Lake was estimated .At the same fime,the amount of Nitrogen and Phosphorus into Lake were also estimated.Finally,we dis-cussed the application of USLE mcdelma Qionghai Basin.
