长江三角洲地区城市空间演化趋势

THE TREND OF URBAN SPATIAL EVOLUTION IN THE CHANGJIANG RIVER DELTA

随着改革开放形势的深入发展,我国沿海经济发达地区之一的长江三角洲,近20年来,经济发展十分迅速,城市区域的基础设施日臻完善,城市之间的各种社会、经济和科技文化联系加强,区域集聚、轴线发展由点到面不断扩大,城镇工业化、现代化水平不断提高,城乡一体化,成为该经济发达地区城市空间演化的最大特征和基本发展趋势。本文结合该区若干城市发展的典型实例分析,着重研究经济发达地区城市空间演化的基本特征、动力机制与功能变化及其城市空间演化的趋势。

Following the reformation and open-door policy, the Changjiang River delta, one of the e-conomy developed coastal areas in China, shows that the city is being industrialized, the region is being urbanized, and the city and countryside are merging into an organic whole. In the recent twenty years, the economy of this delta has developed rapidly. At the same time, the regional infrastructure has been improved day by day; the social, economical, cultural and technological relations among cities have been reinforced; the urban district has spread from a point to a area by the way of agglomeration and axis-pattern extension; and the level of industrialization and modernization of the city has been heightened continually. Therefore, in the economy developed areas, the main features and the radical trend of the urban spatial evolution appear in the form that the city and the countryside merge into an organic whole owing to agglomeration, reciprocal attraction and reciprocal dispersion of the cities. This paper mainly studies the fundamental characteristics, dynamic mechanism, function variations and the trend of the urban spatial ex-pansion in developed areas, together with a lot of typical cases of cities in the Changjiang River delta.
