摘要
概述了森林生态环境服务功能的价值核算基础和现状,并以海南岛尖峰岭热带林生态系统定位研究站过去几十年的研究结论和参数,对海南岛热带天然林的生态环境服务功能价值进行了核算,总价值达43 9×108元人民币·a-1,其中森林固定CO2的价值占20 53%,O2释放价值占22 82%,森林凋落物制肥效益占6 44%,固土价值占0 81%,保肥价值占4 19%,蓄水价值占13 49%,调洪补枯价值占24 70%,改善环境价值占7 02%。按单位面积计算,热带原始林的价值接近7000元·hm-2·a-1,天然更新林超过6500元·hm-2·a-1。最后对海南岛以热带天然林为主的生态公益林补偿提出了建议。
The evaluation of the forest ecological service values is summarized, and based on the research results of the past 2 decades in Hainan Island by Jianfengling Longterm Research Station for Tropical Forest Ecosystems (JLRS), the values for ecological service function of natural tropical forest in Hainan Island were calculated by means of methods of the forestation cost, equivalence prices substitution and environmentrepaired cost and so on The total value of the islands forest was up to 439×108 RMB yuan per year, of which the carbon dioxide absorption occupied 2053% of the total, the oxygen releasing 2282%, fertilizermake by litterfall 644%, soil erosion protection 081%, nutrients keeping 419%, water storage in soil 1349%, floodwater adjusting in rainy season and water supply in dry season 2470%, and improving environment for ecological tourism 702% The value of the primary rain forest in Hainan is near to 7 000 RMB yuan·hm-2·a-1 and the secondary rain forest is more than 6 500 RMB yuan according to the market prices at the end of 1999
