摘　　要：以漾濞核桃林为研究对象,基于《森林生态系统服务功能评估规范》(GB/T 38582-2020)对漾濞县核桃林全口径碳中和能力与生态产品价值进行测算评估。结果表明:漾濞核桃林生态产品价值为113.72亿元/年,其中核桃古树与种质资源保护价值和林木产品供给价值占比较高,二者之和占生态产品总价值的63.30%。漾濞核桃林全口径碳捕获量为13.98万吨/年,其中植被层固碳量为12.70万吨/年,土壤层固碳量为1.28万吨/年;植被层固碳中的果实固碳量占总捕获量比例最高,为32.29%;全口径碳封存量为13.15万吨/年,以就地封存为主,漾濞核桃林生态产品价值实现率为25.70%。测算经济林碳中和能力与生态产品价值,能为推动区域生态产品价值实现、践行碳中和战略提供参考依据。Taking the walnut forest in Yangbi County as the research object,a scientific evaluation was conducted 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 relatively 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 vegetation layer carbon sequestration,the proportion of fruit carbon sequestration to total capture is the highest,at 32.29%;the total carbon storage capacity is 131500 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 economic 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.
