Abstract:

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 results of the ecological service value of forest resources using the coefficient adjustment method are basically consistent with the results measured according to the Specification for the Assessment of Forest Ecosystem Service Functions (LY/T 1721—2008), which can reflect the value amount of ecological service benefits of forest resources within a reasonable error range and meet the requirements for the preparation of forest resources balance sheet. Finally, the coefficient adjustment method for assessing the ecological service value of forest resources, which is proposed for the preparation of forest resources balance sheet, can also serve for the assessment of ecological service value of other natural resources in theory, thus providing a theoretical basis for exploring the measurement of ecological service value of other natural resources.
