摘 要:五台山地区是我国特殊生态环境连接带,以五台山地区为研究对象,从生产、生态、生活功能三方面对研究区农田生态系统服务价值进行评估。结果表明:2003-2012年,研究区农田生态系统的服务功能总价值整体上升,从2003年的61 510.42万元增长到2012年的422 656.88万元,增长了大约6倍。其中,生产功能从2003年的201 057.9万元增加到2012年的609 034.2万元,增长了大约3倍;生态功能价值从2003年的-140 332.964万元下降到2012年的-187 181.13万元,呈逐年下降趋势;生活功能价值基本稳定在800万元左右,波动较小。该研究结果对于人们客观认识农田生态系统的生态效益,地方政府正确处理经济发展与生态保护之间的关系具有重要意义。Wutai mountains area is a specially ecological environment zone. This paper took Wutai mountais area as the research object and assessed the farmland ecosystem service value which contained production function, ecological function and life function. The resuits showed that: The total service value of farmland ecosystem overall rised from 61 510. 42 × 10^4 yuan in 2003 to 422 656. 88 × 10^4 yuan in 2012 ,which grew by about 6 times from 2003 to 2012. Meanwhile,the production function value of farmland ecosystem in the research area increased from 201 057. 9 × 10^4 yuan in 2003 to 609 034. 2 × 10^4 yuan in 2012 which increased by about 3 times from 2003 to 2012 ;the ecological function value of farmland ecosystem declined from -140 332. 964 × 10^4 yuan in 2003 to -187 181.13 × 10^4 yuan in 2012 which decreased year by year;the life function value was basically stable at 8 × 10^4 yuan from 2003 to 2012. The results had great significance not only for people to objective understand the ecological benefits of farmland ecosystem bur also for local government to correctly handle the relationship between economic development and ecological protection.
