摘要
2017年1-9月,采用查阅资料、实地踏勘及3S技术,对重庆市三峡库区消落带面积及岸线长度进行调查和数据分析。结果显示,消落带总面积为268.54 km^2,岸线总长4811.68 km。将岸线划分为664个岸段单元,采用多因素叠加分析,将664个岸段单元,划分为陡坡型、平坝型、岛屿型、库尾型、峡谷型5种基本类型。结合消落带及岸线周边社会经济环境特征,按照综合治理、生态修复和保留保护3种消落带保护与治理类型分干、支流进行分类界定。综合治理、生态修复和保留保护3种类型消落带面积分别为25.78,12.11,230.65 km^2,涉及岸线长度分别为323.77,176.42,4311.49 km。据此,根据不同的消落带类型提出相应的治理与保护对策和建议。
Investigations and analysis were carried out by field survey,3 S technology and references during January and September of 2017 on area water-level-fluctuating zone in Three Gorges Reservoir zone of Chongqing and length of shoreline.The result demonstrated that there were 268.54 km^2 of the water-level-fluctuating zone and 4811.68 km of shoreline in Chongqing,which could be divided into 664 units.The units were divided into five types,such as steep slope,plateau,island,etc.According to comprehensive social and economic environment in the water-level-fluctuating zone and shoreline,integrated management,ecological restoration and conservation were recommended,with area of 25.78 km2,12.11 km^2 and 230.65 km^2,and shoreline of 323.77 km,176.42 km and 4311.49 km respectively.
