Abstract

Abstract:

Determining the carrying capacity of ecological resources is the key to finding contradictions between human activities and the environment, as well as the links between economic growth, environmental protection and social development. In recent years, the carrying capacity of the ecological environment has been extensively studied at home and abroad. Through extensive literature research and analysis, this paper discusses the current status and main problems of recent research on the carrying capacity of the ecological environment in China. For example, two of the main problems are that: 1) the concepts and connotations are not clear enough, and 2) the research content is not systematic enough. This is followed by a summary of the evaluation index system and main calculation methods. Finally, according to the research status and development trends at home and abroad, the possible direction for the development of this research field in the future is proposed.

Key words: ecological resources, environment carrying capacity, accounting method, green ecological space quantification, green quantification index system
