面向空间布局优化的智能规划系统与应用

SMART PLANNING SYSTEM AND APPLICATION FOR SPATIAL LAYOUT OPTIMIZATION

国土空间规划需要加强空间布局优化研究,规划师应具备分析和评价方案空间绩效的能力。构建面向空间布局优化的智能规划模拟评价系统SimPlan,集成二十多种模型和七大维度评价体系,通过“智能模拟—智能评价—迭代优化”工作流,全面支持总体空间布局统筹优化和向详细规划的精准传导落实。以鄂尔多斯市中心城区开发边界内详规统筹为案例开展应用,通过对总规空间布局方案的模拟评价和系统诊断,在用地调整、交通系统规划、空间结构、设施布局等多个方面提出了优化策略和指引,有效支撑了上下联动的空间布局统筹优化。认为SimPlan基本实现了可解释、善学习、能推广、高效率的设计目标,能够在国土空间规划实践中发挥重要作用,也为智能方案生成与优化奠定了方法论基础。

Territorial planning needs to strengthen the study of spatial layout optimization,and planners should have the ability to analyze and evaluate the spatial performance of schemes.This paper develops a simulation-based smart planning system(SimPlan),a smart planning simulation and evaluation system designed for spatial layout optimization.It integrates over 20 models and seven-dimensional evaluation systems.Through a workflow of smart simulation,smart evaluation,and iterative optimization,SimPlan comprehensively supports the improvement of the overall spatial layout and its precise transmission to detailed planning.Taking the integration of detailed planning within the development boundary of Ordos central city as a case study,the paper applies SimPlan to simulate,evaluate,and systematically diagnose the spatial layout scheme of the master planning.It puts forward strategies and guidelines for improving land use adjustment,transportation system planning,spatial structure,facility layout,etc.,which may effectively support the spatial layout optimization through collaboration between upper-and lower-level departments.It is believed that SimPlan has largely achieved its design goals of being interpretable,capable of learning,able to be promoted,and efficient,and can play an important role in territorial planning practices.Additionally,it lays a methodological foundation for smart optimization techniques.
