摘　　要：珠江上游天生桥水电站工程在建设和开发过程中,因为蓄水、风力侵蚀以及人为过度开垦,土地退化问题较为严重。运用实地调查法、资料收集法和ARCGIS成图法,研究天生桥水电站工程建设中土地受水蚀、风蚀和人为过度开垦等因素影响,土壤物理和化学性质发生变化,导致土地质量降低,引起生态系统失衡,致使土地生物特性和经济特性退化。提出从政策支持、土地适度利用、完善土地植被生态系统、加大科技资金投入,建立土地退化预警机制等治理措施出发,解决土地退化问题。In the Pearl River Upstream Natural Arch Hydropower Station in the process of construction and development, because oI the water storage, wind erosion and man-made excessive reclamation, land degradation problem is more serious. This paper, by ap- plying the method of field survey, data collection method and ARCGIS mapping method, studies natural arch in the construction of hydropower project land by water erosion, wind erosion and man-made factors such as excessive reclamation, soil physical and chem- ical properties change, results in the decrease of land quality, causes imbalance in the ecosystem, biological characteristics and economic characteristics of land degradation. We put forward the moderate utilization of land from the policy support, improve land vegetation ecosystem, increase investment in science and technology funds, establish an early warning system for the land degradation control measures, such as solving the problem of land degradation.
