北京城市办公集聚区空间联系强度研究

A STUDY ON SPATIAL LINKAGE STRENGTH OF BEIJING OFFICE CLUSTERS

对城市办公集聚区空间联系研究的目的有两个,一是有助于认知集聚区的现状特点和作用,并为集聚区发展提供指导;二是为后续的城市功能空间优化研究提供基础。通过对适合城市办公活动空间联系强度的哈夫引力模型的修正,基于已有研究成果,对北京城市内部具有代表性的4个办公集聚区之间的空间联系强度进行定量分析。结论表明,办公集聚区的空间联系强度差异显著,且呈现出随距离衰减特征;同时,办公集聚区之间的空间联系方向性明显,总体来看,表现为由外城区向核心区流动的特征,而中关村办公集聚区的空间联系在4个代表性办公集聚区中表现最为活跃。

There are two aims for the study on spatial linkage strength of office clusters.One is to help for acknowledging the office clusters’ existing situation and role.The other is to provide the research basis of subsequence study on layout of urban spatial function optimum.This paper use to the method of Half Gravity Model and base on the fore-results of Beijing office clusters,give to a quantitative analysis on spatial linkage strength among four representative office clusters.For the results,in Beijing city,there is an obvious different for the clusters and a feature of distant attenuation.Meanwhile,there is an obvious direction between office clusters.Generally,the direction of clusters flows from outer city to inner city.According to the analysis of spatial linkage strength,Zhongguancun office cluster is the most activate cluster of four representative clusters in Beijing city.
