城市蔓延是当今世界许多大城市普遍面临的问题。20世纪90年代以来,长春城市蔓延特征逐渐凸显并日趋严重,随之产生许多经济、社会和生态方面的负面效应。城市经济的高速发展、人口增长与空间扩散、开发区建设、机动化与交通设施建设、住宅扩散与郊区房地产开发以及城市规划的宏观导向等因素,都在不同程度上导致了长春的城市蔓延。为遏制长春“摊大饼”式的空间扩张和进一步的城市蔓延,借鉴国内外有效控制城市蔓延的相关理念和应对策略,从城市增长模式、空间优化布局、房地产开发控制与引导、快速交通体系建设、耕地与生态系统保护等五个方面提出了长春城市发展过程中消减城市蔓延的调控路径。
Urban sprawl is the common problem faced by many cities in today's world. Since the 1990s, the features of urban sprawl have emerged and become more and more serious, leading to many negative effects in the fields of economy, society and ecology. The rapid development of ur- ban economy, population growth and spatial diffusion, construction of development zone, motorization and construction of traffic facilities, residence diffusion and suburban real estate development, as well as macro urban planning, have contributed to the urban sprawl of Changchun. To control spatial expansion with circle-spread type and urban sprawl, based on the inter-external experiences of some ideas and strategies to control the urban sprawl, this paper put forward regulation pathways to control urban sprawl of Changchun from five aspects including the mode of urban growth, optimizing urban spatial layout, controlling and guiding of real estate development, construction of rapid transit system and protection of farmland and ecosystems.
