Estimation of Net Forest Carbon Stock and Analysis of Influencing Factors in Yunnan Province——Based on the Dual Perspective of Carbon Source and Carbon Sink
Taking forests in Yunnan Province as the research object,based on the 9th Forest Resources Inventory Report and Yunnan Statistical Yearbook,this paper analyzes the carbon storage of trees,understory plants and forest land in the forest ecosystem by using the stock expansion method,and calculates the carbon emissions caused by forest fires and pests and rodents,and then estimates the net forest carbon storage in Yunnan Province from 2014 to 2018.Principal component analysis and regression analysis were used to conclude that forest stock and forest management and protection area were the main controlling factors affecting forest net carbon storage in Yunnan Province,and forest stock,forest fire area and pest occurrence area were the key factors,which provided a reference for further improvement of forest net carbon storage capacity.
