以长株潭城市群城市森林为研究对象,对其降温增湿、涵养水源、保持土壤、固碳制氧、净化空气、保护生物多样性等生态系统功能进行了初步估算.结果表明:该地区森林生态系统的降温增湿价值为5.32亿元、涵养水源价值为48.10亿元、保持土壤价值为0.096亿元、固碳制氧价值为99.24亿元、净化空气价值为34.60亿元、保护生物多样性的价值为0.13亿元.该地区城市森林生态系统服务功能的总价值平均每年为187.486亿元.%By taking urban forests in Chang-Zhu-Tan area as the research objects, six forest ecosystem services were evaluated such as cooling and humidification, water conservation, soil conservation, fixing carbon and making oxygen, purifying air and protecting biodiversity. The results show that the annual integrated forest ecosystem service in Chang-Zhu-Tan area amounted to 187. 486 billions yuan, of which, 5. 32 billions yuan for temperature reduction and humidification, 48. 10 billions yuan for water-holding, 0.096 billions yuan for soil conservation, 99.24 billions yuan for CO2 fixation and O2 manufacture, 34.60 billions yuan for air purification, and 0. 13 billions yuan for biodiversity protection.
