经济发达区内大都市用地空间的理性扩展

城市化是当今时代社会经济发展的主旋律与经济发展实现现代化的主要目标之一。在经济发达地区,工业化水平高、城镇密集、交通发达、土地利用空间高度集约化,也是沿海地区城市化的重要特点。然而,每个城市的用地空间在城市化过程中存在着非理性的扩展现象,甚至有些大城市地区用地失控的现象;使之城市边缘地区过度郊区化,无限制的蔓延扩展,开发区泛滥,造成生态环境恶化,非理性化的城市建设成本不断增加,社会与环境治理成本也不断加大。提出在经济发达地区内,大都市用地空间理性扩展的5个原则与5种解决的办法,在中国土地资源十分有限的国情条件下,大都市建设做到用地空间理性扩展以及城市化健康发展将起到重要的指导作用,具有十分重要的实践意义与学术价值。

Rational Expansion of Land Use Space in Metropolis of Developed Areas

Urbanization is not only the main theme of the contemporary society but also the main goal of China’s modernization. Transport is normally well –developed in the developed areas. Moreover, these areas are of intensive industrialization and urbanization as well as land use. However, going with the fine phenomenon mentioned above, there is also lots of reasonless phenomenon in these well-developed areas. The reasonless phenomenon covers the over-suburbanization in the marginal urban, unlimited expansion and development. All these result in deterioration in the ecological environment, overuse of the land and the increasing costs of the urban construction and social and environmental treatment. This paper explores five rational principles and five solutions of metropolitan land use space in China's developed areas. Based on the premise of China’s limited land resources, this paper will be of important practical significance and academic value to the rational expansion in metropolis.
