摘要
海南省拥有中国最大的红树林面积(占33%),其品种多、长势好,具有很高的价值;目前缺少对其生态系统服务功能价值的全面评估。文章以整个海南岛红树林湿地为研究对象,综合考虑红树林湿地温室气体排放产生的负价值及其净化空气的正价值等,对其生态系统服务价值进行全面估算研究。结果表明,其生态系统生态服务总价值为187 583.51×104 CNY,单位面积价值为333 234.17 CNY/hm2,远高于全球和中国的平均单位面积价值。其中,温室气体排放产生的负价值为1198.05×104 CNY,占0.64%,净化大气的价值为1027.92×104 CNY,占0.55%。间接使用价值占总价值的49.61%,说明人们更应重视红树林湿地给人类带来的各种生态服务价值而非直观的经济价值。
Hainan Island has the largest mangrove with mang varieties, vigorous growth and high value. Currently few studies have been focused on estimating the value of ecosystem services comprehensively. This paper aims to estimate the value of the services in Hainan mangrove wetland ecosystem with a study of mangrove wetland in Hainan Island, considering the negative effects of Greenhouse Gas Emissions and the value of cleaning air. This study has shown that the ecological functions value of mangrove wetland in Hainan province reaches 187 583.51×10^4CNY, with the value up to 333 234.17 CNY/hm^2, which is higher than the average of the world. The negative value caused by CH4 is 1198.05×10^4CNY, which accounts for 0.64%, and the value of cleaning air is 1027.92×10^4CNY, which accounts for 0.55%. Its indirect use value is accounting for 49.61%, which proves that people should pay more attention to the value of ecosystem services rather than direct economic value of the mangrove wetland.
