摘要
以西藏林芝地区的森林生态系统为例,应用市场价值法、影子工程价格法和生产成本法等,首次定量评价了林芝地区涵养水源、保护土壤、固定CO2、净化空气和游憩功能等森林生态系统服务功能的生态经济价值。结果表明,林芝地区森林生态系统服务功能价值平均每年达到883.91亿元,其中涵养水源价值为651亿元;保护土壤价值为37.63亿元;固定CO2的价值为68.35亿元;净化空气价值为124.94亿元;游憩功能的价值为1.99亿元。
This paper took the forest ecosystem in the Linzhi area of Tibet as an example, and quantitative evaluating the ecological economic values, including watcr-holding, soil protection, CO2 fixation, air purification and tourism and so on forest ecosystem service functions in the Linzhi area for the first time. The results showed that forest ecosystem service function of annual average values reached to 8 839.1 million yuan ,of which, about 6 510 million yuan for water-holding, 376.3 million yuan for soil conservation, 683.5 million yuan for carbon fixation, 1 249.4 million yuan for air purification, and 19.9 million yuan for tourism.
