森林生态价值核算研究--以中林集团雷州林业局有限公司为例

Research on Forest Ecological Value Accounting:Taking Leizhou Forestry Bureau Co.,Ltd.of Zhonglin Group as an Example

以中林集团雷州林业局有限公司5种林龄类型作为研究对象,从固碳制氧、涵养水源、净化空气、土壤保持、森林康养等5方面核算森林生态价值人工林。结果表明:2021年公司森林生态总价值132418.17万元,其中固碳释氧价值82733.96万元,涵养水源价值44832.12万元,净化空气价值190.39万元,土壤保持价值4066.4万元,森林康养价值595.3万元。成熟林、近熟林生态价值高且分别与其面积、蓄积具有相关一致性,价值核算结果为当地森林生态价值的实现提供一定参考。

Plantation forests of five age types of Leizhou Forestry Bureau Co.Ltd.of Zhonglin Group were taken as the research objects,and the ecological values of these plantations were calculated from five aspects,including carbon fixation and oxygen production,water conservation,air purification,soil conservation and forest health.The results showed that total forest ecological value ofthe Company was 1324.18millionyuan in 2021,including 827.34 millionyuan for carbon fixation and oxygen release,448.32million yuan for water conservation,1.90million yuan for air purification,40.66 millionyuan for soil conservation,and 5.95 million yuan for forest health.The ecological value of mature forest and near-mature forest is high and correlated with their area and accumulation respectively.The results of ecological value accounting can provide a reference for the understanding and realization of local forest ecological values.
