以闽江流域为研究区域,采用Costanza等人对全球生态系统服务价值的测算方法,结合遥感技术,提取闽江流域各个县市的水域、林地、草地、耕地和其他用地的专题信息,实现闽江流域生态服务功能价值以及流域内生态公益林生态服务价值的估算.研究结果表明:1986-2003年,闽江流域生态服务功能的价值发生很大变化,体现了人为干扰对生态系统的影响.2003年闽江流域生态服务功能价值较1986年增加3.147×1018元,林地贡献最大;生态公益林生态服务功能价值的增长量为4.137×1018元,占总增长量的37.093%.闽江流域生态服务功能价值增长率可划分为较低、一般、较高、高四个等级,对增长率处于10%以下的15个县市,应更加注意在经济发展的同时,加强对植被资源的保护.闽江流域生态公益林各生态服务功能价值增长趋于均衡化.1986年生态公益林生态服务功能的价值为3.570×1018元,2003年为4.737×1018元,净增1.167×1018元,年均增加6.867×1016元.各县市生态公益林生态服务功能增长率除沙县和三明为负外,其他县市均为正,福州和长乐更是保持100%以上的增长率,这受益于政府相关保护和鼓励政策.
Taking Minjiang River Basin as the research area, Costanza et al. Adopted the method of estimating global ecosystem service value and combined with the remote sensing technology to extract thematic information of water, woodland, grassland, cultivated land and other land in all counties of Minjiang River basin, The value of ecological service function of the river basin and the ecological service value of the ecological public welfare forest in the basin were estimated.The results show that the value of the ecological service function in the Minjiang River basin changed greatly from 1986 to 2003, which reflected the influence of human disturbance on the ecosystem. In 2003, the value of ecological service function in Minjiang River Basin increased by 3.147 × 1018 yuan compared with that in 1986, and the contribution of forest land was the largest. The value of ecological service value of ecological public welfare forest increased by 4.137 × 1018 yuan, accounting for 37.093% of the total increase. The value growth rate of service functions can be divided into four levels: lower, average, higher and higher. For 15 counties and cities with the growth rate below 10%, more attention should be paid to the economic development while strengthening the protection of vegetation resources. The value of ecological service function of ecological public welfare forest in Minjiang River basin tends to be balanced.The value of ecological service function of ecological public welfare forest in 1986 was 3.570 × 1018 yuan, Year was 4.737 × 1018 yuan, a net increase of 1.167 × 1018 yuan, with an average annual increase of 6.867 × 1016 yuan.Each county and city ecological public welfare forest ecological service function growth rate except Shaxian and Sanming is negative, other counties are positive, Fuzhou and Changle is more than 100% to maintain the growth rate, which benefit from government-related protection and encouragement policies.
