Abstract

Since the concept of sustainable development was put forward, China has paid more and more attention to the construction of ecological civilization and has placed greater emphasis on ecological environmental protection. Based on the entropy method, this paper combines entropy change analysis and information entropy to evaluate the sustainable development capability of the ecosystem in Tangshan City. The results of the study indicate that the ecological carrying capacity of Tangshan City has increased to some extent between 2011 and 2016, but the pressure on the ecosystem of Tangshan City is also increasing. The pressure caused by human activities on the environment is gradually decreasing, and the ecological environment has been improved. During the study period, the ecosystem of Tangshan City developed in an orderly and healthy direction. The decline in raw coal production, the increase in industrial electricity consumption and the increase in population are not conducive to alleviating the pressure on the ecological environment in Tangshan City. The comprehensive utilization of industrial solid waste needs to be improved. Based on the above results, proposals were made to increase the output of raw coal, increase energy efficiency, and further increase the overall utilization rate of general industrial solid waste.
