海南中部山区森林生态系统服务功能价值评估

海南中部山区是全省生态功能的核心区，对维持全岛生态平衡与可持续发展起着十分重要的作用。本文依据2005年SPOT2、SPOT4遥感影像（10米分辨率）所提取的专题图层分析统计出中部山区森林生态系统类型和面积，提出了各类型生态系统服务功能评价指标沐系，分为提供产品、调节功能、文化功能和支持功能4种类型；并利用生态经济相关理论基础对备服务功能价值进行了初步评价．结果表明，海南中部山区森林生态系统8种类型9种服务功能总价值为1549．5×10^8元／a，其中调节功能达1472．8×10^8元，占总服务功能价值的90％以上。为进一步提高人们的生态环保意识和促进海南生态补偿机制的建立提供重要参考。

Forest Ecosystem Services and Their Valuation in the Central Mountainous Areas of Hainan

The value of regulating services is 1 472.8 × 10^8yuan, accounts for more than 90% of the total value. Which provides important reference for further improving people＇s eeo - environmental awareness and Promoting the establishment of ecological compensation mechanism in Hainan province.
