长江经济带岸线资源调查与评估研究

岸线资源是重要而特殊的国土资源与国土空间,在江河沿岸地区经济社会发展和生态环境建设中发挥重要的支撑作用。基于遥感解译、部门座谈、实地勘察和采样测试等技术方法,对长江经济带干支流岸线资源开展了系统的调查评估分析。结果表明,岸线资源条件存在较大的空间差异,岸线资源生态敏感程度较高,开发与保护协调困难,岸线利用对滨岸带水环境和水生态产生影响,局部岸段健康风险突出,滨江湿地呈萎缩、破碎化趋势。从岸线资源空间管控等方面提出政策建议,以期为促进长江经济带绿色高质量发展、生态环境保护规划及国土空间规划等战略和工作提供参考借鉴。

Investigation and Assessment of Waterfront Resources in the Yangtze River Economic Zone

Based on the technology and method of the remote sensing survey, field sampling, evaluation and classification of the waterfront resources, the investigation and analysis of the natural basis and using status of the waterfront in the Yangtze River Economic Zone are carried out. The resources conditions, ecological sensitivities, using status as well as their ecological environment impact are revealed, the zoning scheme and use policy for the management on the waterfront resources in the Yangtze River Economic Zone are put forward, which is a scientific approach to the management on the waterfront resources in the Yangtze River Economic Zone. Firstly, the waterfront resources utilization should be strictly managed by the different control measures according to the classification: prohibiting utilization areas, optimizing utilization areas, restricting utilization areas; secondly, the illegal occupation that do not meet the development policy and the requirements for the environmental safety should be cleaned up to promote the eco-environmental quality; Thirdly, the ecological restoration in the areas of the waterfront in which the industry has been cleared out, or in the heavily polluted areas should be carried out according to the natural attributes and the ecological function of the waterfront in the Yangtze River Economic Zone. Fourthly, management organization and mechanism with multi-sector coordination and effective regulations in the utilization of the waterfront should be established to ensure the safety of flood control and water supply, support the social and economic development and form the green, efficiency and intensive utilization pattern of the Yangtze River Economic Zone.
