摘要
研究目的:探索基于“资源环境承载能力评价和国土空间开发适宜性评价”的国土空间格局优化路径,为土地利用结构与布局优化、“三条控制线”划定等国土空间格局优化提供理论与方法参考。研究方法:文献综述法、归纳演绎法与地理空间模型法,融合“自上而下”的承载能力约束与“自下而上”的适宜性评估,以“数量管控—空间布局—多目标协同”的逻辑主线进行国土空间格局优化。研究结果:(1)基于“双评价”的国土空间格局优化需考虑尺度与区域差异;(2)以表征资源环境承载能力的极限约束作为多目标优化的数量约束,融合开发适宜性的空间转换规则及空间约束,构建国土空间格局优化模型,能够为生态、农业和城镇空间的合理布局提供优选方案;(3)基于“双评价”的区域多目标优化,强调生态安全、经济发展与社会保障等多目标协同,将提供促进区域空间均衡的国土空间格局优化方案。研究结论:基于“双评价”的国土空间格局优化可有效耦合多目标,推动国家空间治理体系与治理能力的现代化。
The purposes of this paper are to explore the optimization path of territorial space pattern based on evaluation of resources and environment carrying capacity and territorial space suitability and to provide theoretical and methodological references for land-use structure and location optimization as well as three regulation boundary delineation,etc.The methods of literature review,inductive and deductive analysis and geospatial model are employed in this paper,optimizing the territorial space pattern under the framework of“quantity control,spatial layout,and multi-objective collaboration”.The results show that 1)optimization of territorial space pattern based on“resources and environment carrying capacity and land suitability assessment”should consider the scale and regional differences.2)Taking the carrying capacity of resources as the quantitative constraints,coupling spatial conversion rules and spatial constraints according to territorial suitability assessment,multi-objective optimization could be built to provide alternatives for rational land-use patterns regarding ecological,agricultural and urban spaces.3)Based on the“resources and environment carrying capacity and land suitability assessment”,multi-objective optimization pays more attention to the coordination of ecological security,economic development,social security,and provides alternatives of territorial space optimization for regional space coordination.In conclusion,the optimization of territorial space pattern based on“resources and environment carrying capacity and land suitability assessment”will effectively couple multiple objectives,and promote the modernization of territorial space governance system and governance capacity.
