耦合MOP-FLUS模型的滇中城市群“三生”空间格局优化

生产空间、生活空间、生态空间之间联系紧密,决定国土空间的最高演化目标,为了协调区域经济社会的发展,通过构建符合城市群发展实际的“三生”空间分类体系划定国土空间; 基于目标条件与情景设定,通过MOP模型实现“三生”空间综合效益最大化; 利用FLUS模型优化“三生”空间布局,并采用景观格局指数对其优化结果进行了分析评价。结果表明:优先满足生产和生活空间发展情景的生态效益最低,城镇化进程加快的同时生态空间发展受到抑制,生态环境脆弱; 优先满足生态空间发展情景的经济效益最低,生态环境虽然得到良好保护,但同时生产与生活空间面积占比较小,分布破碎,不利于区域经济发展; “三生”空间均衡协调发展情景的经济效益提高4.46%,生态效益提高1.87%,空间布局均衡统一。因此该情景能够合理平衡生态建设与经济发展,在丰富生态过程和格局结构上具有优越性,可为滇中城市群国土空间资源配置、“三生”空间优化等决策提供一定的参考和借鉴。

Production-Life-Ecological Space Pattern Optimization of the Urban Agglomeration in Central Yunnan Based on Coupled MOP and FLUS Model

Production space, living space and ecological space are closely linked, which determines the highest evolution goal of land space. In order to coordinate the development of regional economy and society, we defined the land space by constructing the production-life-ecological space classification system in line with the reality of urban agglomeration development, and maximized the comprehensive benefits of the production-life-ecological space through MOP model based on the target conditions and scenario setting, the FLUS model was used to optimize the spatial layout of production-life-ecological space, and the landscape pattern index was used to analyze and evaluate the optimization results. The results show that the ecological benefits of giving priority to the development of production and living space are the lowest, the development of ecological space was restrained and the ecological environment was fragile while the process of urbanization was accelerated; the economic benefits of giving priority to meeting the development scenario of ecological space were the lowest; although the ecological environment was well protected, the area of production and living space was relatively small and fragmented, which was not conducive to regional economic development. The economic benefits of the production-life-ecological space spatial balanced and coordinated development scenario increased by 4.46%, the ecological benefits increased by 1.87%, and the spatial layout was balanced and unified. Therefore, this scenario can reasonably balance ecological construction and economic development, and has advantages in enriching ecological process and pattern structure. It can provide some reference for decision-making such as land spatial resource allocation and production-life-ecological space spatial optimization of urban agglomeration in Central Yunnan.
