Multi-scale simulation and optimization research on the evolution of urban agglomeration's territorial spatial structure
城市群国土空间结构演变的多尺度模拟与优化研究

摘要

城市群国土空间结构演变是区域协调发展的重要研究领域。随着城市化进程的加速，城市群空间结构的优化对资源合理配置、生态环境保护和区域可持续发展具有重要意义。本研究通过多尺度模拟方法，分析城市群国土空间结构的演变特征，探讨其驱动机制，并提出优化策略。研究构建了多尺度空间模型，结合地理信息系统（GIS）和元胞自动机（CA）技术，模拟城市群空间结构的动态变化。结果表明，城市群空间结构演变受到自然地理条件、经济发展水平和政策导向的综合影响，优化策略需兼顾生态保护与经济发展。

Abstract

The evolution of the territorial spatial structure in urban agglomerations is an important research area for regional coordinated development. As urbanization accelerates, optimizing the spatial structure of urban agglomerations is crucial for the rational allocation of resources, ecological environment protection, and sustainable regional development. This study analyzes the evolutionary characteristics of the territorial spatial structure of urban agglomerations through multi-scale simulation methods, explores its driving mechanisms, and proposes optimization strategies. A multi-scale spatial model was constructed, integrating Geographic Information Systems (GIS) and Cellular Automata (CA) technologies to simulate the dynamic changes in the spatial structure of urban agglomerations. The results show that the evolution of the spatial structure of urban agglomerations is influenced by a combination of natural geographic conditions, economic development levels, and policy orientations. Optimization strategies need to balance ecological protection and economic development.
