摘要
对生态系统服务的物质量评价和价值量评价这两类评价方法进行比较 ,分析了这两类评价方法的优点和缺点 .结果表明 ,采用物质量和价值量两种不同的方法对同一个生态系统进行服务评价 ,往往会得出不同甚至相反的结论 ;对于不同的评价目的和不同的评价空间尺度 ,这两类评价方法的作用是有较大区别的 。
Physical assessment method (PAM) and value assessment method (VAM) for ecosystems services assessment were compared, and their strengths and weaknesses were analyzed. The comparison and analysis demonstrated that in some cases,different, even opposite results will be drawn with these two methods for the ecosystems services assessment of one ecosystem. The functions or effects of PAM and VAM are different for different assessment purposes or different spatial scales, but they will promote and complement each other to some extent.
