| 摘 要： | 基于8次森林资源清查和森林生态连清技术体系获得的生态和资源大数据，对海南省近40年的森林资源动态变化和森林生态系统服务功能进行研究。结果表明:海南森林资源面积、蓄积和生态功能实现了“三增长”，海南省森林面积自1981年起呈逐年增加的趋势，在第5次清查期（1994—1998年）后逐渐趋于稳定，在第8次清查（2009—2013年）后达最大的97.11万hm2，增长幅度为1.63倍；第3次至第8次清查期海南省森林蓄积有逐渐增加的趋势，清查期资源数量有大幅度上升，森林蓄积量增长了32.61%；从第3次至第8次清查，海南省森林生态系统各项服务功能总体呈增加趋势，涵养水源第3次清查为34.82亿t·a，第8次为82.56亿t·a，增加了137.11%；滞尘从3次清查为93.33亿kg·a，第8次为235.01亿kg·a，增加了151.81%；海南省“十一五”“十二五”期间的森林生态系统服务功能价值量分别为126.59亿元·a和1 359.67亿元·a，增长幅度为20.69%；阔叶混交林服务功能价值量达最大值。研究结果对进一步提高人们对森林资源保护意识、推动国民经济核算体系和生态文明建设制度的构建具有重要的意义。

| Abstract: | Dynamic change of forests and the service functions of the forest ecosystem in Hainan in recent 40 years were analyzed based on data from the eight forest inventories in Hainan and from continuous observation of the forest ecosystems and periodical forest inventories in Hainan. The results showed that the area, stock volume and ecological functions of the forests in Hainan had achieved "three rounds of growth". Since 1981, the forest area has been increasing year by year in Hainan. The forest areas was gradually stabilized after the fifth forest inventory (1994—1998), and was maximum (9 711 000 ha) after the eighth inventory (2009—2013), increasing by 2.63 times as compared to the third forest inventory. The stock volume of the forests in Hainan tended to increase from the second to the eighth forest inventories, and greatly from the third to the eighth inventories, increasing by 32.61%. From the third to the eighth forest inventories, the service functions of the forest ecosystem showed an increasing trend in Hainan. Water conservation was increased by 137.11%, from 3.482 billion t·a in the third forest inventory to 8.256 billion t·a in the eighth forest inventory; dust retention from 9.333 billion kg·a in the third forest inventory to 23.501 billion kg·a in the eighth forest inventory; the value of the forest ecosystem service functions during the 11th and 12th Five-Year Plan period was 112.659 billion yuan·a and 135.967 billion yuan·a in Hainan, respectively, increasing by 20.69%; the broadleaf mixed forests had the highest value in ecological service function. The findings are of great significance to further enhance people's awareness of forest protection, and promote the construction of national economic accounting system and the ecological civilization.ilization. |
