城市用地扩张和绿地生态网络增效的空间耦合与智能协同优化研究

From the perspective of coupling of city and green space, this project analyzes the interaction between urban land expansion and green space ecological network synergism in spatial and effect dimensions, and studies the spatial hierarchy, elements and coupling characteristics of the coupling space to analyze coupling model, coupling process and coupling function of coupling space, which breaks through effect measurement index system and spatial measurement index system of coupling space and establishes the multi-objective constraint system and its cooperative optimization path. In addition, cell automata and multi-agent algorithm are integrated to construct the collaborative coupling and intelligent optimization model of urban land expansion and green space ecological network synergism. Based on the above theoretical research, through the case study of Nanchang City, Jiangxi Province, the paper illustrates how to integrate the symbiosis and co-optimization of space and time so as to realize the scientific and intelligent urban space planning layout. Overall, the project provides a new research approach for the simulation of urban space optimal allocation, and also the theoretical and methodological support for urban development and spatial comprehensive control.
