城市空间拓展动力机制及生态模型

我国目前正处于城市空间高速拓展的时期,但对城市空间释义的理论体系不完善,缺乏对空间拓展机制的全面解析,其中对生态要素的研究尤其需要加强.笔者采用理性分析的手法,提出我国城市正处于空间拓展生态转型的关键时期,认为影响城市空间拓展的力分为动力与阻力2种,并建构了相应的生态模型,结果表明这一生态模型的建构有助于更加全面地认知城市的发展,并提出了应用于规划创新的几种可能方式,对城市规划方法具有明确的指导作用.

The Research on the Capacity Mechanism of City Space Expanding and Its Ecological Model

In the period of the city space expanding with the high speed, the theories system used to explain the city space is not perfect in our country. It is lack to expand this mechanism, among them research ecosystem' s main factors to particularly should be enhanced, especially the ecological factor. With rational analysis, the paper puts forward the viewpoint that the urban space is in ecological changing period, and considers that the power affecting the urban space expand involves motivity and resistance. Building the corresponding ecological model helps to cognize the city development roundly with ecological model constructed. A few possible ways is put forward which can be used in planning innovation, and have vivid leading function to the frondose city planning method.
