海南省近海生态系统服务功能价值评估

参照联合国《千年生态系统评估项目》,构建了海南省近海生态系统服务功能体系。采用传统经济价值评估方法,对所构建的10类服务功能进行了定量评估。结果表明:2013年海南省近海生态系统服务功能评估值约为862.52亿元,单位面积海域评估值约为2 811 200元/km~2,低于临近省份广东和广西。其中,文化服务价值最大,占44.19%;其次为供给服务,占36.50%;调节服务价值最小,仅占19.31%。评估结果反映出海南省海洋资源开发潜力仍非常大,海洋生态产业转型迫在眉睫。海南省近海生态系统的污染物处理能力非常有限,在滨海旅游开发中应引起关注。

Function Value Assessment of Offshore Marine Ecosystem Service in Hainan Province

Referring to the United Nations Millennium Ecosystem Assessment Project (MA), offshore marine ecosystem service function system in Hainan Province was constructed.The 10 service values of the ecosystem functions were evaluated by traditional economic valuation methods. The results showed that the annual total value of offshore marine ecosystem services of Hainan Province was about 86 252 hundred million yuan in 2013, with an average value of offshore marine ecosystem services per unit sea area of 2 811 200 yuan/km2 which was lower than neighboring provinces of Guangdong and Guangxi.The cultural service had the greatest value, accounting for 44.19%, followed by supply service, 36.50%. The adjustment service had the least value, accounting for 19.31%.Assessment results revealed that marine industrial system in Hainan is still dominated by the traditional industry , the marine ecological resources were slowly developed and pollutant treatment capacity of offshore marine ecosystem was very limited, which should be paid more attention in coastal tourism development .
