Research on the Delineation Method of"Three Zones and Three Lines"in National Land Space Planning

为保证国土空间规划的合理性,文章总结了“三区三线”的相互关系和划定原则,从开发适宜性和资源环境承载力两方面出发,评价了城镇空间、农业空间、生态空间的等级,并阐述了永久基本农田红线、生态保护红线和城镇开发边界的划定方法,研究成果可为国土空间规划中的“三区三线”划定提供理论依据。

In order to ensure the rationality of national land space planning,this paper summarizes the relationship and delineation principles of"three zones and three lines".From the aspects of development suitability and resource and environmental carrying capacity,it evaluates the grades of urban space,agricultural space and ecological space,and expounds the delineation methods of permanent basic farmland red line,ecological protection red line and urban development boundary.The research results can provide theoretical basis for the delineation of"three zones and three lines"in national land space planning.
