岸线资源利用的空间过程、机理与模式研究——以长江岸线为例

作为一种新兴和特殊的战略资源，岸线资源处于水陆交互带，承载临岸港口、工业、城镇和湿地等人类活动和自然生境，发挥重要的经济社会和生态环境功能，其利用与布局问题逐步成为学术界和政府部门关注的焦点。作为中国乃至全球最典型的港口-工业-城镇密集带，长江岸线面临空间无序、“化工围江”、生态退化等重重困境。项目以长江岸线作为研究对象，拟在构建岸线资源时空数据库的基础上，识别港产城等不同类型、上中下游不同区段岸线资源利用的空间过程与特征；选择和剖析岸线资源利用格局演变的关键驱动要素，定量揭示各要素的影响贡献和指向特征，刻画典型岸段和微观港区、工业区空间演变的驱动过程与机理模式；开展中远期岸线利用布局情景设计，提出空间管控与优化建议。本研究不仅为促进大保护战略下的岸线资源利用优化布局提供决策参考，同时也可以丰富区域空间、流域经济、自然资源等相关理论研究。

As a new and special strategic resource, waterfront resources are in the land-water interaction zone which carries human activities and natural habitats such as ports, industries, towns and wetlands, and plays an important roles of economic, social and ecological environment. Use and layout of waterfront resources have gradually become the focus of attention in academic circles and government departments. As the most typical port-industrial-urban economic belt in China and even in the world, the Yangtze River waterfront faces many difficulties such as spatial structure and ecological impact. So this project takes the Yangtze River waterfront as the research object. It is proposed to identify the spatial process and characteristics of the waterfront resources utilization in different types and watersheds on the basis of constructing a spatial-temporal database. Select and analyze the key driving factors for the evolution of waterfront resource utilization patterns. Quantitatively reveal the impact contribution and directional characteristics of each factor, and characterize the driving process and mechanism model of the spatial evolution of typical shore sections, micro-port areas, and industrial areas. Carry out scenario design of medium and long-term waterfront utilization layout, and propose space management and control and optimization suggestions. This research not only provides decision-making reference for promoting the optimization of the waterfront resource utilization under the national environmental protection strategy, but also enriches the related theoretical research on regional space, river basin economy and natural resources.
