应用环境地质学与岩土工程学相结合的方法，提出三峡库区区域性地质环境因素是控制该区重力侵蚀发生发展的基本环境因素．建立由其决定的库区重力侵蚀基本模式、稳定性判据及工程地质稳定区段．在此基础上，探讨了重力侵蚀对三峡库区城镇地质环境影响的评价以及对城镇形成、发展、变迁、消失、规模、功能及格局的作用．这对促进库区城镇发展、山区开发和经济发展有重要意义
By means of the combination of environmental geology and geotechnical engineering, it is proposed that the regional geological and environmental factors in the Three Gorges reservoir area are the basic environmental factors controlling the occurrence and development of gravity erosion in this area. Establish the basic model, stability criterion and engineering geological stability section of reservoir gravity erosion determined by it. On this basis, the paper also discusses the evaluation of the impact of gravity erosion on the urban geological environment in the Three Gorges Reservoir Area and its role in the formation, development, change, disappearance, scale, function and pattern of urban areas. This is of great significance to promoting urban development in the reservoir area, developing mountain areas and economic development
