通过分析珠三角小流域生态环境存在的问题,论述了水土保持生态环境建设的目标和原则,指出应以小流域为单元,从流域整体角度开展水土保持生态环境建设,通过采取各种生态及工程措施,在上游改善林地生态功能,下游河道整治修复河流生态功能,改变水库消涨带的景观,同时注重开发建设项目水土保持,才能提升小流域内各类生态系统功能,促进区域水土保持生态可持续发展。 By analyzing the existing problems in the ecological environment of the Pearl River Delta, the objectives and principles of ecological environment construction are discussed. It is pointed out that the construction of soil and water conservation ecological environment should be carried out from the perspective of the whole basin by taking the small watershed as a unit. By adopting various ecological and engineering Measures to improve the ecological function of the forestland in the upper reaches, the ecological function of the river restoration in the lower reaches of the river, the change of the landscape of the zonal desiccation zone, and the focus on the development and construction of soil and water conservation can enhance the functions of various ecosystem in the small watershed and promote the sustainable development of soil and water conservation in the region Continuous development.
