Abstract: 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 Long term 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 environment repaired cost and so on The total value of the islands forest was up to 43.9×108 RMB yuan per year, of which the carbon dioxide absorption occupied 20.53% of the total, the oxygen releasing 22.82%, fertilizer make by litter fall 6.44%, soil erosion protection 0.81%, nutrients keeping 4.19%, water storage in soil 13.49%, floodwater adjusting in rainy season and water supply in dry season 24.70%, and improving environment for ecological tourism 7.02% The value of the primary rain forest in Hainan is near to 7 000 RMB yuan·hm-2·a-11 and the secondary rain forest is more than 6 500 RMB yuan according to the market prices at the end of 1999.
