集约导向的城市空间发展评价与机制分析——以江阴为例

Development Evaluation and Mechanism Analysis of the Intensive-oriented Urban Space: A Case Study of Jiangyin

在土地资源紧张的基本国情下,集约发展是城市发展的有效途径和必然选择。集约的城市空间具有外部形态紧凑、内部结构合理、土地利用高效的特点。该文以江阴为例,建立城市空间发展评价体系,对城市外部形态、内部结构和用地效率进行评价,分析其粗放型形态的形成机制,认为区域地位、交通条件等外部发展条件限制、社会经济粗放发展模式、城市管理效率低下是城市空间粗放发展的主要原因。提出划定增长边界控制空间蔓延、公共交通引导内部结构优化、强度分区与建设总量控制等优化措施和政策建议。

The scarcity of land resources is China＇s basic national conditions, intensive development is the inevitable choice for China＇s urban development. Compact external morphology, reasonable urban structure and efficient land use are characteristics of intensive urban space. In this paper, we establish an evaluation system to evaluate the development of urban space including urban external morphology, internal structure and land-use efficiency, and choose Jiangyin as an example. External conditions, such as regional status and traffic conditions, extensive development mode of socio-economy and inefficient urban management are main mechanisms for the extensive development of the urban space. Finally, we present measures such as delineation of urban growth boundaries to control urban sprawl, public transport guiding the improvement of urban structure, building intensity partition, the total control of construction and so on to optimize the urban space.
