摘要
目前,有关红树林生态系统服务评估的研究基本未考虑红树林湿地温室气体排放问题。以海南东寨港红树林湿地为研究对象,采用考虑温室气体排放负面效应的生态系统服务功能价值评估体系,对红树林生态价值进行全面评估。结果显示,东寨港红树林湿地生态系统服务价值为71 661.69×104 CNY,CH4排放产生的负价值为569.33×104 CNY,占0.79%;略低于景观美学与精神文化功能价值(0.86%),但高于有害生物的控制价值(0.03%),考量CH4排放产生的负价值在红树林生态价值评估体系中有其必要性。
The present studies on assessment of ecological function,; of mangrove wetland are rarely in terms of greenhouse gas emissions from mangrove wetland. This paper aims at mangrove wetland in Dongzhai Port of Hainan, applying the ecological functions assessment system with a view to negative effects of greenhouse gas emissions, in order to make a comprehensive assessment of ecological functions. It proves that the ecological functions value of mangrove wetland in Dongzhai Port reaches CNY 716 616 900, and the negative value caused by CH4 is CNY 5 693 300, accounting for 0.79%, lower than the functions value of landscape aesthetics and spiritual culture （0.86%） while higher than the controlling value upon pests （0.03%）. It is essential to consider the negative value from CH4 emissions in the ecological functions assessment of mangrove wetland.
