运用《森林生态系统服务功能评估规范》的相关标计量参数、指标和共识,对海南省红树林生态系统服务功能的总价值进行评估,并对不同市(县)红树林生态服务价值进行分析。研究表明,海南省红树林生态系统服务功能核算成经济后的总价值为26828.08万元,单位面积价值为6.58万元·hm-2。其中,有机物生产价值2780万元,固土保肥价值34.54万元,气体调节价值6241.62万元,积累营养物质价值490.48万元,净化环境价值5221.23万元,防灾护提价值1645.03万元,生物多样性保育价值6112.60万元,生态旅游价值4302.59万元。

Mangrove is a typical natural landscape in tropical coastal zone, South China. It has important economic value, ecologi- cal value and social value. Using opportunity cost method, shadow engineering method and consulting some formulas in ＂Specifica- tions for assessment of forest ecosystem services in China＂ we assessed the economic value （year 2012 ） of mangrove wetlands eco- systems in Hainan Province. The results showed that the total value of Halnan mangrove forest ecosystem services was 268.2808 mil- lion Yuan, 65.8 thousand Yuan per hectare. The value of organic production was 27.8 million, the value of soil reinforcement and fertility maintenance was 345.4 thousand, the value of carbon fixation and oxygen release was 62.4162 million, forest nutrition stor- age value was 4.9048 million, the value of purify the environment was 52.2123 million, disaster prevention value was 16.4503 mil- lion, biodiversity conservation value was 61.1260 million, the value of tourism and ecological culture was 43.0259 million.
