我国城市蔓延的动力机制

Driving Forces of Urban Sprawl in China

我国城市蔓延的动力机制与发达国家有一定差异。人口增长、经济发展、机动交通和信息技术的发展引起了城市空间的快速扩张。当城市空间的扩张缺乏有效的规范和引导,导致土地利用效率低下时,城市空间就会进入一种无序蔓延的发展状态。而我国城市蔓延问题的根源应当归结于政策制度的缺陷。因此,城市蔓延的控制重在土地的集约化利用和政策制度的完善。

Driving forces of urban sprawl in China are different from that in developed countries. Population growth, economic development, traffic and information technological development lead to rapid expansion of urban space. Lack of effective guidance and standardization of urban land expansion gives rise to low efifciency use of urban land, namely urban sprawl. Moreover, the root of urban sprawl in China is ascribed to the lfaws of policy and institution. Therefore, the key point of urban sprawl control in China should be intensiifcation of land use and perfection of policy and institution.
