市域国土空间格局多维度分解与传导路径

国土空间格局对协调区域保护与开发具有重要保障作用，其基本前提在于厘清国土空间格局内涵并构建科学有效的传导路径。由此提出国土空间格局多维度分解与传导路径研究框架，围绕生态保护、农业生产和城镇建设三个方面开展适宜性评价，基于国土空间潜在冲突识别与调解机制实现国土空间重构，运用区位熵识别优势功能分区，进而构建战略格局，并以东营市为例开展案例研究。研究发现：东营市国土空间适宜性表现为“生态保护重要、农业生产和城镇建设适宜”，潜在冲突以中度为主；国土空间重构包括农业空间、生态空间和城镇空间，地理单元的空间分异和行政单元的面积占比差别明显；优势功能分区包含重要生态功能区、农产品生产区、城市化发展区和弹性发展区，提供了分区分类的差别化管控策略；国土空间保护与开发战略格局包括“一心一屏一廊”的生态保护格局、“一圈两区”的开发利用格局和“两带”的弹性发展格局，树立了可持续国土空间利用的目标引领。研究结果可为新时期国土空间规划编制与实施以及协调区域国土资源有效配置提供有益借鉴。

Research on multi-dimensional decomposition and conduction path of territory spatial pattern at the municipal level

Territory spatial pattern plays an important role in coordinating regional protection and development. Its basic premise is to clarify the connotation of territory spatial pattern and build a scientific and effective conduction path of territory spatial pattern. Based on the logic lines of "raster-land category-administrative region-whole area" and "suitability evaluation-territory spatial reconstruction-dominant function identification-regional consistency abstraction", this study develops a research framework for territory spatial pattern scale decomposition and conduction path. Firstly, the suitability of territorial space is assessed in terms of three aspects: ecological protection, agricultural production, and urban construction, with the type, intensity, and spatial pattern of territory spatial potential conflict identified using a model for identifying territory spatial potential conflict. Secondly, the "rigid constraint" and "elastic guidance" planning mechanisms are applied to mediate potential conflicts in territorial space and reconstruct the territorial spatial pattern. Finally, the location entropy model is utilized to determine the dominant function of territorial space and to establish a strategic plan for territory spatial development. Dongying city is used as an example in this research to conduct an empirical study. The results show that: (1) The territory spatial suitability of Dongying is crucial for ecological protection, suitable for agricultural production and urban construction, and the potential conflicts of territorial space are mainly moderate. (2) Ecological space, agricultural space, and urban space are all part of the territory spatial reconstruction. From coastline and coastal areas to inland regions, the boundary between protection and development in geographical units is 19.69 km and 1.6 km, respectively. The proportions of territory spatial reconstruction patterns, on the other hand, vary substantially between counties (cities and districts). (3) Dominant function zones include important ecological function zones, agricultural production zones, urbanization development zones and elastic development zones that provide differentiated control strategies for zoning classification. (4) The ecological protection pattern of "one heart, one screen, and one corridor", the development and utilization pattern of "one circle and two districts," and the flexible development pattern of "two belts" comprise the strategic pattern of territory spatial protection and development, which establishes the goal of sustainable territory spatial utilization. The findings of this study can be used as a guide for developing territory spatial planning and coordinating the effective allocation of regional territory and resources in the New Era.
