大城市边区城市化特征和核心城市功能地域规划策略——以广州市白云区嘉禾组团为例

Urbanization Characteristics of Urban Fringe and Land Use Planning Strategies of Core Functional Areas： A Case Study of Jiahe Cluster at Guangzhou＇s Baiyun District

城市化转型是大城市边缘区的发展趋势，包括经济、人口、用地、交通、景观等方面特征的具体转变。本文以广州市白云区嘉禾组团为例，分析大城市边缘区现状发展特征。结合大城市主城区空间和功能拓展等趋势，分析边缘区城市化的普遍趋势：产业从工业主导向服务业主导转型，用地从城乡交错向布局有序转型，交通功能从对外通道向内外网络转型，景观环境从杂乱污染向山水融城转型。进而提出核心城市功能地域在边缘区城市化转型中的重要作用，提出核心城市功能地域应科学合理划定发展范围、培育具有功能带动和辐射作用的城市功能、构建与主城区紧密联系的城市快速交通设施和构建满足城市功能和城市活动需求的景观设施。

Urbanism is the trend of Urban Fringe, including the urbanism transformation of economy, population, land use, transportation and landscape. This essay figure out the characteris- tics of urban fringe by taking Jiahe in Guangzhou as a case： economic structure shifts from manufacture-leading to service-lead- ing, land use model shifts from mosaic to orderly, the function of traffic system shifts from corridor to urban commutation network, and landscape shifts from polluted to attractive. Basing on these characteristics, this essay points out the importance of the core urban functional area in the process of urban fringe urbanism. Deter- mining the boundary, connecting to urban center, building up the rapid traffic system, providing the open space for urban style activi- ties are all the critical planning strategies of the core urban func- tional area.
