Carbon Neutrality Assessment and Green Accounting of Ecological Product Value for Walnut Forests in Yangbi County
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.
