城乡统筹视角下基于分形量化模型的游憩绿地系统布局优化

分形理论是研究复杂巨系统典型形态特征的前沿理论，采用分形理论衍生的聚集维量化模型和形态维量化模型对上海游憩绿地系统进行演化特征的时空分析，基于演化特征和相关规划提出游憩绿地系统布局分形耦合重构的优化方案：8中心5级分形的结构布局优化和大尺度郊野公园的形态布局优化，研究结果表明，测算出的演化特征结果更为符合实际情况，优化方案能进一步促成系统结构形态的分类分级演化、增强系统形态稳定性能、普遍提升服务水平并缩小空间差异，可被有效地用于城乡范畴下的游憩绿地系统规划中。

Optimization of Recreational Green Space System Layout Based on Fractal Quantification Model from the Perspective of Urban-rural Integration

The fractal theory is a frontier theory for the study of the typical morphological characteristics of complex giant systems. This paper draws lessons from the aggregated dimensionality model and the morphological dimensionality model of the fractal theory to make a fractal analysis of the spatio-temporal evolution of the recreational green space system in Shanghai. Based on the research conclusion and relevant planning, this paper puts forward the optimization scheme of fractal coupling reconstruction: the structural layout optimization of 5 level fractal in 8 centers and the morphological layout optimization of large-scale country parks. The results show that the evolutionary characteristics are more in line with the actual situation, and the optimized scheme can further promote the classification and grading evolution of the system structure, enhance the stability of the system morphology, generally improve the service level and narrow the spatial differences, and can be effectively used in the planning of the recreational green space system in urban and rural areas.
