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 eco...
