【摘要】 森林是地球上最重要的多功能生态系统,它不仅为人类社会提供多样的实物产品,同时也蕴藏着巨大的生态价值,其中固碳释氧价值更是地球生命支持的基础.研究根据2008年完成的滇池流域森林资源调查数据,采用材积源生物量法以及碳税法和造氧成本法,计算出森林生态系统固碳释氧服务价值.结果表明,滇池流域森林生态系统固碳释氧服务价值为331.576×10~7元/a,其中固碳服务价值为188.452×10~7元/a,释氧服务价值为143.124×10~7元/a.滇池流域目前所有植被种类中云南松(Pinus yunnanensis)的固碳释氧服务价值是最高的,达到39.649×10~7元/a.单位面积竹林(Bambusoideae)的固碳释氧能力最强,每年每公顷竹林固碳释氧服务价值是50 409.519元,目前滇池流域内竹林面积很小,增加竹林种植面积可以作为未来森林改建计划,进一步提高森林生态系统固碳释氧服务价值.更多还原

【Abstract】 Forests are the most important multi-functional ecosystems on earth which not only provides various physical products for human society, but also contains tremendous ecological value. To calculate the ecosystem service value of carbon fixation and oxygen release in the forest of Dianchi Lake Basin, the volumederived biomass method, carbon tax method and oxygen production cost method were applied based on the forest resources survey data of Dianchi Lake Basin in 2008. The results showed that the ecosystem service value of carbon fixation and oxygen release was 331.576×10~7 Yuan per year, of which the service value of carbon fixation was 188.452×10~7 Yuan per year and the service value of oxygen release was 143.124×10~7 Yuan per year. Pinus yunnanensis had the highest service value of carbon fixation and oxygen release among all the vegetation types in Dianchi Lake Basin, which was 39.649×10~7 Yuan per year. And Bambusoideae had the strongest ability of carbon fixation and oxygen release in per unit area, with service value of carbon fixation and oxygen release being50 409.519 yuan per hectare per year. At present, the area of Bambusoideae in Dian Lake Basin is very small.Increasing Bambusoideae planting area can be used as a forest reconstruction plan and to improve the service value of carbon fixation and oxygen release in forest ecosystem in the future.更多还原
