“双评价”对国土空间格局优化支撑作用分析
Analysis on the Supporting Role of “Double Evaluation” in the Optimization of Territorial Space Pattern

通过分析“双评价”对国土空间格局优化的支撑作用，为生态保护、农业和城镇发展以及“三区”和“三线”划定提供参考。采用文献综述法、归纳演绎法和指标分析法，结合《“双评价”指南》(试行)从评价指标分析逐步深入探讨“双评价”在底线约束、生态保护、农业发展、城乡发展和安全等五大格局优化的支撑作用。基于资源环境承载能力和国土空间开发适宜性评价2个主要方面，从5大空间格局入手，构建国土空间格局优化框架，并提出国土空间格局优化中需重点考虑生态优先原则，重视生态环境保护。同时基于“双评价”结果，对国土空间开发格局和未来国土开发存在的潜在风险进行预判，识别冲突区并分析其原因，进而提出预防措施，为区域国土空间格局和土地利用结构优化提供参考。
By analyzing the supporting effect of “double evaluation” on the optimization of the land space pattern, it provides references for ecological protection, agricultural and urban development, and the delineation of “three districts” and “three lines”. Using literature review method, inductive deduction method and index analysis method, combined with the “Double Evaluation” Guide (Trial) to gradually and deeply explore the bottom line constraint, ecological protection, agricultural development, urban and rural development and security pattern of the “double evaluation” from the evaluation index analysis optimized support. Based on the two main aspects of resource and environment carrying capacity and the suitability evaluation of land and space development, starting from the five spatial patterns, the optimization framework of land and space patterns is constructed. It also pointed out that in optimizing the spatial pattern of the land, it is necessary to give priority to the principle of ecological priority and to attach importance to the protection of the ecological environment. At the same time, based on the results of the “double evaluation”, it predicts the land space development pattern and potential risks of future land development, identifies conflict areas and analyzes their causes, and then proposes preventive measures to provide reference for the optimization of regional land space pattern and land use structure.
