摘要
地下空间需求量是制定城市地下空间开发战略目标和规划布局的重要基础。分析了城市地下空间需求量预测的作用与意义,总结了现有的3种城市地下空间需求量预测的方法,即分指标预测法、分系统预测法和分区位预测法,并分析了3种预测方法各自的优点与不足;提出了将分指标、分系统与分区位相结合并考虑需求时效性的综合预测法,阐述了综合预测法的总体思路,并分析了其优点。在综合预测法的基础上,提出了建立城市地下空间需求分布体系,建立了该体系的三维结构模型,讨论了该体系的建立方法。结果表明,将综合预测法所得到的预测结果导入地下空间需求分布模型,能使该模型具体化。
Demand for underground space is the foundation of strategic objective and planning of urban underground space.The function and significance of the demand forecasting of urban underground space were analyzed,three existing methods for demand forecasting,that are classified-index forecasting method,classified-system forecasting method and classified-location forecasting method were summarized and discussed,and their individual advantages and disadvantages were analyzed.A comprehensive forecasting method which combined all three forecasting methods mentioned above was proposed,with a consideration of the time-effectiveness of underground demand.The underlying concepts and advantages of the comprehensive demand forecasting method were then discussed.Based on the comprehensive forecasting method,a demand distributional system of urban underground space and its three-dimensional model were developed.The results show that the forecasting results of the comprehensive forecast method imported into the demand distribution model for underground space can make the mode specific.
