山西薛公岭省级自然保护区森林生态系统服务功能价值评估

Assessment of Forest Ecosystem Service Function Value in Shanxi Xuegongling Provincial Nature Reserve

本研究通过外业调查并运用市场价值、影子工程和机会成本等方法,对山西薛公岭省级自然保护区森林生态系统服务功能价值进行评估。结果表明,薛公岭保护区森林生态系统服务功能总价值量为134169.12万元/a,各服务功能价值量排序为净化大气环境>涵养水源>固碳释氧>固土保肥>保护生物多样性>积累营养物质>森林游憩。其中,乔木的服务功能价值量为10.22×10^(8)元/a,灌木的服务功能价值量为3.17×10^(8)元/a,主要树种价值量大小为油松>辽东栎>山杨>华北落叶松>白桦>侧柏。

The value of forest ecosystem services in Shanxi Xuegongling Provincial Nature Reserve was evaluated through field investigations and using market value,shadow engineering,opportunity cost methods.The results showed that the total value of forest ecosystem services in Xuegongling Nature Reserve was 1.3416912 billion yuan/a,and the order of value of each function was purification of atmospheric environment>water conservation>carbon sequestration and oxygen release>soil and fertilizer conservation>biodiversity protection>nutrient accumulation>forest recreation.Among them,the service value of the trees was 10.22×10^(8)yuan/a and the service value of shrubs was 3.17×10^(8)yuan/a.The value of the main tree species was in the order of Pinus tabulaeformis>Quercus liaotungensis>Populus davidiana>Larix gmelinii>Betula platyphylla>Platycladus orientalis.
