City fringe area landscape ecological planning under the green ring - Green wedge mode - To set the ecological ring zone of Chengdu as an example

摘要

Since the reform and opening up, Chinese urban construction has made great achievements. Meanwhile, it also brings a range of urban problems which seriously affect people's living conditions. How to build urban ecological structure and how to improve the urban living environment have increasingly drawn people's attention. Seated on the special location of urban ecological pattern, the urban fringe, with great ecological functions and greater room to maneuver, is an important aspect of improving the urban environment. Due to overly restrained urban development, traditional green ring pattern has beenin controversy. However, it is an important measure to complement Green Belt Policy by adding green wedge to the pattern under the guidance of model of Patch-Corridor-Matrix. This measureis also an important revelation to the planning of domestic circle style urban fringe. It is a reflection of scientific ecological planning on the urban fringe that the first domestic ecological zones around the city was built in Chengdu.
