Abstract

Resource recycling is one of the most important content of ecological civilization construction in China, which is beneficial to reduce the overuse of primary resources exploitation, to reduce the environmental pollutions during the process of resource extraction and waste disposal, and to realize the sustainable development of human economy and society. Resource recycling is a reflection of ecological economic development. Ecology provides a theoretical support for the resource circulation industry development. The ecological theories have played a guiding role. However, there are not enough academic researches to systematically summarize and analyze the relation and connection between ecology and resource recycling. Therefore, we based on the ecological theories to analyze the theoretical basis and application for resources recycling. The results showed that the ecological threshold theory, ecological balance theory, Overall hierarchy theory, the food chain (web) theory, niche theory and so on can be used to explain the resource circulation system such as resources recycling building concepts, resources recycling industry development foundation and the government's role in promoting resources circulation process. Based on the application of ecological theory for constructing the resource circulation system, further analysis of the scientific laws for the government regulation may help understand the concept of resource circulation and essence of circular economic system operation.
