Abstract
Based on the concept of green development, with Yunnan Province as the research object and forest ecological carrying rate as the target layer, two sub-systems of forest ecological carrying capacity and environmental pollution pressure were constructed. The TOPSIS method was used to calculate the forest ecological carrying capacity and environmental pollution pressure index of Yunnan Province from 2011 to 2020, so as to obtain the forest ecological carrying rate. The results showed that: (1) the forest ecological carrying capacity index in Yunnan Province increased first, then decreased and then increased in the past 10 years. (2) The environmental pollution pressure index of Yunnan Province showed an overall rising trend in the past 10 years. (3) The forest ecological carrying rate in Yunnan Province is still in overload state. Therefore, to improve the level of forest ecological carrying capacity in Yunnan Province, it is necessary to formulate relevant policies from two aspects: forest ecological carrying capacity and environmental pollution.
