面向高质量发展的海岸带资源型城市空间治理——基于跨系统影响的视角

海岸带资源型城市是陆海资源高度交错的空间载体，以跨系统影响的视角对其进行空间治理，有助于突破资源型城市转型发展的局限性，实现资源综合效益最大化。首先，本文厘清了跨系统影响的复杂性与海岸带资源的多样性，并以空间资源作为研究的核心要素。其次，强调陆海全系统生态—经济—社会的“综合效益”，以“陆海统筹”作为指引，深化海岸带资源型城市高质量发展的内涵。再次，探索了“关键资源识别—空间效益评价—空间资源调控”的高质量发展空间治理路径。即通过识别跨系统影响范围、开展资源空间调查、明确资源组合模式来甄别关键资源，进而构建包含“综合效益评估”和“跨系统影响修正”的资源空间效益评价框架，明晰各资源空间效益的差异，为空间治理提供决策依据。最后，根据空间效益评价结果，结合国土空间规划要求，在资源空间优化、区域资源统筹、空间总量分配、开发模式引导等方面提出海岸带资源型城市高质量发展的有效调控方式。

Spatial governance of coastal resource-based cities for high-quality development: From the perspective of cross-system impact

Coastal resource-based cities are spatial carriers with highly intertwined land resources and sea resources. From the perspective of cross-system impact, the spatial governance will help to break through the limitations of the transformation and development of resource-based cities, and maximize the comprehensive efficiency of resources. Firstly, this paper clarifies the complexity of cross-system impact and the diversity of coastal resources, and takes spatial resources as the core element of the study. Secondly, it emphasizes the ecological-economic-social "integrated efficiency" of the whole land and sea system, and takes "land-sea coordination" as a guide to deepen the connotation of high-quality development of coastal resource-based cities. Thirdly, it explores the spatial governance path of "key resource identification-spatial efficiency evaluation-spatial resource regulation" for high-quality development. Concretely, we select key resources by identifying cross-system impact scope, conducting resource spatial surveys, and determining the resource combination mode. Furthermore, a resource spatial efficiency evaluation framework including "comprehensive efficiency evaluation" and "cross-system impact correction" is established to clarify the differences of various spatial efficiencies, and provide a decision-making basis for spatial governance. Finally, according to the results of spatial efficiency evaluation, combined with the requirements of territorial spatial planning, this paper puts forward beneficial regulation and control methods for the high-quality development of coastal resource-based cities, in the four aspects of resource spatial optimization, regional resource integration, total space allocation and development mode guidance.
