Analysis and optimization of green ecological infrastructure based on GIS-Taking the new town in the north of Jiangjin District of Chongqing as an example

Abstract

With the rapid development of urbanization, urban ecosystem is facing an unprecedented threat. At the same time, the concept of green ecological infrastructure has attracted more and more attention. In the practice of engineering design, the priority is given to the corresponding analysis and evaluation of green ecological infrastructure. With the aid of ArcGIS software, the analysis is carried out in the process of natural process, biological process and local cultural landscape. On this basis, the evaluation is carried out according to the detailed data, and the optimization strategy is proposed. In order to provide a scientific basis for the later planning and design. Taking the northern new town of Jiangjin District of Chongqing as an example, this paper verifies the rationality and popularization of the analysis and optimization of green ecological infrastructure, which is of great significance to the realization of sustainable and environment-friendly urban future development path.
