摘　　要：以贵阳市环城喀斯特人工林为研究对象,探讨森林生态系统服务功能的内涵,使用市场价值、替代花费等方法定量评估贵阳市环城喀斯特人工林生态系统服务功能的经济价值。结果表明,面积为8.8万ha.的环城人工林生态系统服务功能价值平均每年46,803.56万元。其中林产品价值为8894.68万元、涵养水源价值为9232.48万元、土壤保持减少侵蚀价值为4,105.24万元、固定CO2减轻温室效应的价值为4,484.74万元、净化空气的价值为15,592.63万元、释放O2的价值为339.17万元、科学研究价值为1,846.5万元、生物多样性价值为2,308.12万元。This paper attempts to assess forest ecosystem services and their economic value of man-made forest on Karst landform around Guiyang. The results show that average annual integrated ecosystem service value of man-made forest on Karst landform reaches 468.04 million yuan,with an area of 88,000 hm2,of which about 88.95 million yuan is the output of standing trees and other forest products,about 92.32 million yuan of water-holding,about 41.05 million yuan of soil conservation against erosion,about 44.85 million yuan of carbon fixation for reducing green house effect,about 155.93 million yuan of air purification,about 3.39 million yuan of O2 giving out,about 18.47 million yuan of scientific research,about 23.08 million yuan of biodiversity conservation.
