城市边缘区空间发展关系对城市形态演变的影响——以包头市主城区为例

Impact of Relationships between Spatial Development and Urban Fringe on the Evolution of Urban Morphology——Using the Main Urban District of Baotou as a Research Case

城市边缘区是城市化进程中乡村与城市二者之间要素相互集结、渗透的区域。城市边缘区在发展中会受到自然与人为因素的影响,其与自然要素类空间展现出包含、并列、阻挡三种关系,并对应表现出连续、空洞和线性三种城市形态,呈现出填充、破碎和割裂三种效果。本文以内蒙古包头市城市发展过程为例进行探讨,发现:包含关系是城市边缘区与自然要素类空间之间较为理想的状态,可呈现出连续的城市形态。城市建设时应对城市边缘区这一特殊的地带给予更多关注、进行妥善规划,以更好地促进城市的发展和形态的完整。

The urban fringe is an area where the elements of rural and urban regions aggregate and penetrate into each other in the process of urbanization.The urban fringe is affected by both natural and human factors in the development,and its relationship with the naturalelement space demonstrates the one of inclusion,juxtaposition and obstruction,which correspondingly exhibits three urban morphologies:continuousness,porousness and linearity,presenting the effects of filling,fragmentation and disseverance.This paper explores the urban development process in Baotou,Inner Mongolia,and discovers that the relationship of inclusion is a comparatively ideal state between the urban fringe and the natural-element space,which is able to present a continuous urban morphology.Urban constructions should be paid with more attention and be planned properly for the sake of this special area of urban fringe to better facilitate the urban development and morphological integrity.
