郑州城市边缘区的空间演变、扩展与优化

The Space Evolvement,Expansion and Optimization of Zhengzhou City Fringe Area

在快速城镇化进程中,许多城市的中心城区和边缘地带同时迅速扩展,城市边缘区成为变化最大、问题最多和最敏感的地带,也是城市未来发展的关键区域。近年来,郑州城市边缘区的迅速发展有力地支持了郑州市城市综合竞争力的提升,但其空间格局的不清晰和空间组织的混乱也给城市的可持续发展埋下隐患。郑州城市边缘区空间演变的历史悠长而曲折,景观积累多样而繁杂。当前,郑州城市边缘区的空间扩展主要得益于郊区城镇化和乡村城镇化,扩展方式以轴向扩展与外向扩展为主。郑州城市边缘区的空间优化要满足可持续发展的要求并遵循一定的科学准则,合理确定功能与产业定位,采用科学的空间组织方式,并接受高层次的规划制约。在此基础上,以产业园开发模式为主,实现边缘区空间格局的优化。

In the fast urbanization advancement, both of the central city and its boundary zone of many cities has rapid expansion at the same time, the city fringe area becomes a changing, question and sensitive zone, also becomes the essential zone for the city future development. In recent years, the rapid development of Zhengzhou city fringe area has powerfully supported the promotion of synthesis competitive power of Zhengzhou city. But, its spatial pattern is indistinct, its spatial organization is chaotic, and with a result that lays down the hidden danger to the city sustainable development. The space evolvement history is long and winding with the numerous and diverse landscape accumulation in Zhengzhou city fringe area. Presently, The space expansion of the Zhengzhou city fringe area mainly benefits from the suburb urbanization and the village urbanization, and the expansion ways are primarily the axial expansion and the extroverted expansion. The space optimization of Zhengzhou city fringe area needs to satisfy the sustainable development and follows certain scientific criterions, to determine reasonably the function and industrial localization, to use the scientific spatial organization way, and, to accept the restriction of high level plans. In this foundation, by industrial garden development pattern primarily, Zhengzhou city fringe area realizes the spatial pattern optimization.
