摘　　要：近年来,为了提升饮用水水源地的综合监管水平,遥感监测技术得到了广泛应用。本文中基于landsat8 OLI卫星遥感数据,采用ENVI、Arc GIS等遥感图像处理技术,研究了黄前水库水源地保护区的植被覆盖度及水土流失分布特征。结果表明:黄前水库饮用水水源地保护区的林草覆盖度较高,占保护区总面积的57.32%;而水土流失较为严重,土壤侵蚀面积占55.30%,其中,以轻度、中度为主。该成果为黄前水库饮用水水源地保护区的水土流失监测和生态环境综合治理提供了技术支撑。In recent years,remote sensing monitoring technology has been widely applied in order to improve the comprehensive supervision level of drinking water source.In this paper,based on the remote sensing data of Landsat 8 OLI satellite,remote sensing image processing technologies such as ENVI and Arc GIS are adopted to study the distribution characteristics of vegetation coverage and soil and water loss in the water source protection area of Huangqian Reservoir.The results show that the forest and grass coverage of the water source protection area of Huangqian Reservoir is relatively high,accounting for 57.32%of the total area of the protection area.Soil and water loss is relatively serious,and the soil and water loss area accounts for 55.30%,mainly mild and moderate.The results provide technical support for soil and water loss monitoring and comprehensive management of ecological environment in the water source protection area of Huangqian Reservoir.
