摘　　要：【目的】探索价值量型森林资源资产负债表体系中森林资源生态服务价值计量方法,针对当前森林资源资产负债表编制过程中森林资源生态服务价值计量难题提出新的解决思路,为完善价值量型森林资源资产负债表的编制提供建议咨询方案。【方法】首先,以GZS为参照,采用系数调整法分别测算涵养水源、保育土壤、固碳释氧等调整系数,结合GZS对应的森林资源生态服务价值测算CDS森林资源生态服务价值总量;然后,将系数调整法测算的价值与实际值进行比较,测算误差范围,并分析其合理性。【结果】采用系数调整法测算的CDS森林资源生态系统涵养水源价值59.97亿元,误差5.57亿元;保育土壤价值21.91亿元,误差-4.92亿元;固碳释氧价值74.77亿元,误差5.90亿元;净化大气环境价值30.74亿元,误差4.16亿元;森林资源生态服务价值总量187.39亿元,误差10.71亿元,总体误差6.10%。【结论】1)采用系数调整法评估森林资源生态服务价值能够有效克服传统计量方法成本高、时效性差的问题,引入调整系数可大大降低对指标数据搜集的要求,有效节约地方政府开展森林资源生态服务价值核算的开支;2)采用系数调整法评估森林资源生态服务价值结果与依据《森林生态系统服务功能评估规范》(LY/T 1721—2008)计量结果基本一致,能够在合理误差范围内反映森林资源生态服务效益的价值量,且满足编制森林资源资产负债表的要求;3)针对编制森林资源资产负债表提出的评估森林资源生态服务价值的系数调整法,在理论上还可用于其他自然资源生态服务价值评估,为探讨其他自然资源生态服务价值计量提供理论基础。【Objective】To explore the measurement method of forest ecological service value in the value-based forest resources balance sheet system,to propose new solutions to the difficulties in measuring the ecological service value of forest resources in the current forest resources balance sheet compilation process,and to provide suggestions and consultation solutions for improving the compilation of value-based forest resources balance sheet.【Method】Firstly,the coefficient adjustment method is used to measure the adjustment coefficients of water conservation,soil conservation,and carbon sequestration and oxygen release with GZS as the reference,and the total ecological service value of forest resources in CDS is measured by combining the corresponding ecological service value of forest resources in GZS.Then,the values measured by the adjustment coefficient method were compared with the actual values,the error range was measured,and its reasonableness was analyzed.【Result】The value of CDS forest resources ecosystem water conservation measured by the coefficient adjustment method is 5.997 billion yuan,with an error of 557 million yuan;the value of soil conservation is 2.191 billion yuan,with an error of 492 million yuan;carbon sequestration and oxygen release is 7.477 billion yuan,with an error of 590 million yuan;purifying the atmosphere is 3.074 billion yuan,with an error of 416 million yuan;the total value of ecological services of forest resources 18.739 billion yuan,error 1.071 billion yuan,overall error 6.10%,the error range is acceptable.【Conclusion】First,the adoption of the coefficient adjustment method to assess the ecological service value of forest resources can effectively overcome the problems of high cost and poor timeliness of traditional measurement methods,greatly reduce the requirements for indicator collection by introducing adjustment coefficients,and effectively save local governments’expenses on accounting for the ecological service value of forest resources.Secondly,the assessment
