江西九连山国家级自然保护区森林生态系统服务价值评估

根据九连山自然保护区生态定位研究站的长期观测资料和相关研究成果，调查和搜集九连山森林资源二类调查、森林旅游、林产品等相关数据，对九连山自然保护区森林生态系统服务价值进行评估。九连山自然保护区森林生态系统服务总价值约为11.9亿元/a，高于保护区所属地龙南县2013年财政总收入。其中，维持生物多样性价值最大，约10.8亿元，占总价值的90.8%；涵养水源价值最小，只占总价值的0.06%。各项功能价值顺序为：维持生物多样性价值＞土壤保持价值＞净化空气价值＞固碳价值＞生态旅游价值＞涵养水源价值。本次评估量化了九连山自然保护区亚热带森林生态系统服务，使九连山自然保护区干部职工进一步深化对自然保护工作意义的认识，也为九连山自然保护区的保护和发展提供新的依据，为人们正确认识自然保护区的价值提供数据支持。

Value Estimation of Forest Ecosystem Servicesin Jiulianshan National Nature Reserve of Jiangxi Province

According to long term observed document and relative research achievement of ecological location station of Jiulianshan Natural Reserve, the economic services value is estimated for the forest ecosystem through investigating and collecting the relative data such as second class investigation of Jiulianshan forest resources and forest travel and forest products. The total value of Jiulianshan forest ecosystem is about 1.19 billion RMB per year, which is higher than the financial income of Longnan county affiliated to protection area in 2013. Maintaining biological diversity is the highest value, about 1.08 billion RMB, occupied 90.8% of the gross value. The least value is conserving water resources, only occupied 0.06% of the gross value. The sequence of function value from high to low is： the value of maintaining diversity, the soil conservation value, purified air value, value of carbon sequestration, ecological travel value, value of water conservation. The estimation quantifies the value of the subtropical forest ecosystem in Jiulianshan Natural Reserve, make the employee realize the significance of further protecting natural reserve, provide the new base of the protection and development of natural reserve, and supply the people with the data support to make them realize the value of protecting natural reserve.
