Abstract：In the first half of the 21st century, urbanization is still an important project of the socialist modernization of China. This means that various developing elements will collect further on cities, cities will bear strain on population, resource, and environment, and Chinese cities will be confronted with a grave challenge. Conforming to the objective orderliness of the urban sustainable development, according to the objective requirement of the construction of ecological city, the optimization of urban opening spatial system is an essential channel to promote the healthy development of Chinese urbanization, and a great research topic for the all-round construction of Chinese well-off society in the current and a long hereafter period.
The optimization of urban opening spatial system should proceed from three sides. First side is the readjustment of the spatial distribution structure in a city. The new spatial distribution structure in the city would expand efficacious area of open space system, strengthen the supporting of open space system to ecological capacity of the city, build a base for the integration of the three circles in open space system. Second side is the integration of the three circles in urban opening spatial system. Third side is the construction of the elements in urban opening spatial system. This project has two content. The First is the construction of green opening space. The government should adhere to the urban ecological norm, create high-quality ecological environment, living environment and landscape environment, make plants area, garden area and water area into a natural integration, make point, line and flat green land into an unitary system, thereby, establish a green basis for the construction of ecological city. Second content is the construction of gray open space. The government should adhere to the urban ecological norm, create high-quality ecological environment, operation environment and building environment, make interior traffic, outside traffic, square and parking area into an situation of coordinating development, make lateral roads, longitudinal roads and loop roads into an unitary system, thereby, establish a gray basis for the construction of ecological city.
