中型平原水网城市空间形态特征研究

A STUDY ON SPATIAL FORM AND CHAR AC TERISTICS OF THE MEDIUM-SIZED RIVER PLAIN CITIES

立足于城市空间形态特征规律,总结归纳平原水网城市结构特征和形态构成规律,通过对空间形态结构要素特征的提取,从城市规模、区域地理环境、本体自然地貌及城市格局等多方面,建构该类型城市空间形态结构模型,并将模型解构成七大特征区域,即簇核区、阴影区、基质区、交通线、水绿楔、边缘区和半城镇化区。在此类空间形态模型基础上,结合三个案例进行模型拓扑和模型适用性说明。

Based on the laws of urban spatial form and its characteristics, this paper summarizes the characteristics and formation rules of the river plain cities. And through extracting structural elements of this spatial form, the paper builds a spatial structure model for the medium-sized river plain city from the perspectives of city scale, regional geographical environment, natural landscape, and city pattern. The model can be deconstructed into seven featured areas: cluster core, shadow area, matrix area, traffic line, green wedge, urban fringe, and semi-urbanized area. Based on this model, the paper presents three topological structures and explains the applicability of this model.
