漾濞核桃林全口径碳中和评估与生态产品价值绿色核算OA北大核心CSTPCD

Taking the walnut forest in Yangbi County as the research object,a scientific evaluation was con-ducted on the total carbon neutrality capacity and ecological product value of the walnut forest in Yangbi County based on the'Specifications for Assessment of Forest Ecosystem Service'(GB/T 38582－2020).The results show that the ecological product value of Yangbi walnut forest is 11.372 billion yuan/year.Among them,the protection value of ancient walnut trees and germplasm resources,as well as the supply value of forest products,account for a rela-tively high proportion,with the sum of the 2 accounting for 63.30%of the total ecological product value.The full carbon capture of the walnut forest in Yangbi County is 139800 tons/year,of which the carbon sequestration in the vegetation layer is 127000 tons/year,and the carbon sequestration in the soil layer is 12800 tons/year;in the veg-etation layer carbon sequestration,the proportion of fruit carbon sequestration to total capture is the highest,at 32.29%;the total carbon storage capacity is 131 500 tons/year,mainly for on-site storage.The value realization rate of walnut forest ecological products in Yangbi County is 25.70%.Mastering the carbon neutrality ability of eco-nomic forests and the value of ecological products provides a scientific basis for promoting the realization of regional ecological product value and implementing carbon neutrality strategies.
