    摘要:

    目前国内对生态系统服务的研究多是从供给的角度对生态系统服务的功能量和价值量进行评估,对生态系统服务的消费及其与供给的相互关系重视不够。以传统农业区贵州省从江县为例,利用不同计量方法对当地居民对生态系统服务的消费进行测算,并对当地的生态系统服务供给-消费平衡关系进行衡量。结果表明:(1)价值量方法、能值分析方法和生态足迹方法的计量结果都说明,从江县居民对供给服务的消费构成了生态系统服务消费的主体部分;(2)运用能值分析方法和生态足迹方法得到的负荷能力系数表明,从江县2007年基本上处于生态系统服务供需平衡状态。尽管几种方法各有优缺点,但都不失为计量生态系统服务消费的有效方法。

    Abstract:

    Most studies on ecosystem services in China have been primarily focused on assessments of their functions and values from the perspective of supply. While assessments and methods of ecosystem services valuation are continuously emerging, there has been little attention to assessment of their consumption from the demand perspective or to analyzing the relationship between supply and consumption. This paper was designed to use different methods for measurement of ecosystem services consumption of the traditional agricultural area in Congjiang County, Guizhou Province. This paper also tried to evaluate the effectiveness of the different methods for measurement of ecosystem services consumption and how these methods can measure the balance between supply and consumption of ecosystem services in the county. Results from monetary measurement, emergy analysis and ecological footprint all show that the consumption of provision service constitutes the main part of ecosystem services consumption in Congjiang County. As is shown by emergy analysis and ecological footprint, Congjiang County has a total ecological balance in 2007 which is at breakeven level. Comparison of methods for measurement of ecosystem services illustrates the usefulness of the methods as a tool to monitor and manage our ecological assets although each method of measurement has its own strengths and weaknesses.
