摘要：

通过城市开放空间系统的优化来加强生态城市建设 ,是推动城市进入可持续发展状态的重要途径。本文在阐述生态城市建设的意义、要求和城市开放空间系统优化的必要性的基础上 ,分析了开封市的城市特色和发展的新思路 ,提出了该市开放空间系统优化的理论基础 ,确定了应该遵循的原则。开封市开放空间系统的整体优化应从两方面入手 :第一 ,调整市区的空间布局结构 ,建立新的城市空间布局框架 ;第二 ,强化开放空间系统的圈层一体化 ,给生态城市建设提供强大的空间支持。开放空间系统的要素优化包含两个内容 :第一 ,优化绿色开放空间 ,努力做到林、园、水天然浑成 ,点、线、面密切结合 ;第二 ,优化灰色开放空间 ,努力做到对内交通、对外交通、广场车场协调发展 ,横道、竖道、环道有机结合。

Abstract:

Kaifeng City, one of China ’s "seven ancient capital cities"and an important member of "Zhongyuan city croup", plays an important role as the regional central city of East Henan province in Henan's urban system City open space is a huge container regulating and controlling urban ecosystem In order to bring Kaifeng City into the situation of sustainable development, it is necessary to improve the construction of Kaifeng ecological city by means of optimizing open space system On the basis of the discussions of the significance and requirement of the construction of ecological city and the necessity of the optimization of city open space system, this paper analyses Kaifeng City ’s salient features and new developing ways, and raises theoretical basis and principles for the optimization of Kaifeng City ’s open space system The overall optimization of Kaifeng City ’s open space system should proceed from two sides The first side is the readjustment of the spatial distribution structure of the city The new spatial distribution structure in Kaifeng City should expand effective area of open space system, strengthen supporting of open space system to ecological capacity of Kaifeng City,and build a base for the integration of the three circles in open space system The second side is the integration of the three circles in Kaifeng City ’s open space system The integration in each circle, and between the three circles, should make Kaifeng City ’s open space turning into an integrated and organic system, from which the construction of Kaifeng ecological city should obtain powerful spatial support The element optimization of Kaifeng City ’s open space system has two contents The first one is the optimization of green open space in the city The municipal government should adhere to the urban ecological norm, create high quality ecological, living and landscape environments, make wooded area, garden area and water area into a natural integration, make point, line and flat green land into an unitary system, thereby, establishing a green basis for the construction of Kaifeng ecological city The second one is the optimization of gray open space in the city The municipal government should adhere to the urban ecological norm, create high quality ecological, operational and building environments, make urbantraffic, outside traffic, square and parking area into a situation of coordinated development,makeroads from east to west, from south to north and loop roads into an unitary system, thereby, establishing a gray basis for the construction of Kaifeng ecological city
