摘    要:构建了海南省公益林生态系统服务功能的评价指标体系,依据2009年国家森林资源清查数据、尖峰岭生态定位站连续观测数据、社会公共数据等数据资料,利用影子工程法、替代工程法等方法,首次对海南全省公益林生态服务功能价值(2010年)进行评估。结果显示,海南省公益林生态系统服务功能2010年总价值为1113.60亿元,相当于当年全省生产总值(GDP)2050亿元的54%,单位面积森林提供的服务功能的价值为14.09万元/hm2。由于考虑森林提供负氧离子的功能,8项森林生态系统服务功能价值贡献值之中,净化大气环境>固碳释氧>生物多样性>水源涵养>森林保护>森林游憩>保育土壤>积累营养物质。

关 键 词:公益林生态系统  服务功能  评价指标体系

Abstract:A series of assessment index systems suitable for Hainan public welfare forest ecosystem services were set up.Using shadow engineering method,alternative engineering method,et al,we assessed the economic value(year 2010) of public welfare forest ecosystem services of Hainan Province based on the data from National Forest Continues Inventory,Jianfengling Ecological Orientation Station long-term observation,and social commonality.The results show that the total value of the province’s forest ecosystem services was 111.360 billion Yuan,amounting to 54% GDP of the province in year 2010,and the average forest ecosystem service was 140.9 thousand Yuan per hectare.Considering the value of negative oxide ion,the eight service functions were ordered as environmental purification> carbon fixation and oxygen release> biodiversity conservation>water conservation>forest protection>forest tourism and ecological culture>soil conservation>forest nutrition storage.
Keywords:public welfare forest ecosystem  ecosystem services  assessment index system
