Study on the Construction Model of Xi'an Ecological Community from the Perspective of Material Metabolism

摘要

This paper established an ecological community model to improve the current linear material metabolism model in communities. Through the case study and evaluation criteria of ecological community, the ecological indicators were constructed. The community material circulation metabolism model was established by combining the indicators with the method of material metabolism. Taking Shuizhai community as an example, it was found that most of the materials currently outputted by the community could be processed appropriately and reentered the community to reduce pollution and decrease the demand for new materials. This paper hopes to provide reference for the future ecological community research, and also hopes to reduce the pressure of human activities on the ecological environment.
