中关村科技园区在北京城市空间扩展中的地位与作用

21世纪是知识经济的时代,各种类型的高新科技园区应运而生,研究高新科技园区的发展对城市空间扩展的影响有时代意义。中关村科技园区是北京发展知识经济的基地,在科技园区中具有代表性,本文从中关村科技园区的用地规划、产业规划、交通规划、环境规划入手,分析中关村科技园区建设在北京城市空间扩展中的地位与作用。结果表明,中关村科技园区的建设将加速北京向郊区化方向发展,同时吸引高素质人才聚集西北地区,其中心区有可能成为北京城市的副中心,从而促进北京大都市多中心格局的形成,同时诱发产业轴线空间发生战略性转移,使得西北-东南轴向成为北京大都市最重要的空间扩展轴。在上述分析的基础上,本文对北京市总体发展规划提出了建设性的修订意见。

Roles and Functions of Zhongguancun Science Park in the Spatial Extension of Beijing

21th century is one of the important stages of know ledge economy in our society.High Technological Parks, as kinds of growing poles, are playing important roles in urban spatial extension. This research mainly studies the roles and functions of Zhongguancun Science Park (ZSP) in Beijing's metropolitan development.Because ZSP will be the base for Beijing's knowledge economy, it will have great potential influence on the spatial ex tension of Beijing metropolis.Based on the analysis, several conclusions, concerning with the development of land use, industrial sector, transportation and environmental protection, are put forward.
Firstly, the development of ZSP will help the city to extend likely star-shapedlandscape pattern with more reasonable suburbanization, especially in the northwest of Beijing.The five sub-division parks, which cooperate each other to organize the whole ZSP, will become new fulcrums for the city to ex tend because of rapid suburbanization in the future.
Secondly, the development of ZSP will place a premium on shifting pivot movement of industrial sector in Beijing, therefore, spatial overall arrangement will be mo re meaningful for functional arrangement with the know ledge economy.
Thirdly, ZSP will attract mo re and mo re high-educated people to work and live within the park and its surrounding s, especially in the northwest part of Beijing. Fourthly, the center of the park will become one of the sub-business centers in the metropolitan of Beijing, which has distinct function namely know ledge economic function compared w ith CBD.
Finally, the authors give some advice for the possibility of modifying Beijing's overall city plan in the future.Because suburbanization of Beijing is stepping into rapid period, the future overall plan should pay sufficient attention to the roles of ZSP in accelerating suburbanization process of Beijing.
