摘  要:Costanza等提出的生态服务价值化评估方法在中国直接运用存在一些缺陷:低估或者忽略了某些生态系统服务价值。因此,笔者在其生态系统服务价值评估体系的基础上分别在2002年和2006年对中国700位具有生态学背景的专业人员进行问卷调查,得出了新的生态系统服务评估单价体系。通过对比发现,调查获得的基于专家知识的生态系统服务单价体系与基于物质量估算的生态系统服务价值之间具有较好的可比性。该基于专家知识的生态系统服务评估体系可以用于已知土地利用面积的生态系统服务价值估算,能在较短时间内获得较为精确的结果。

Valuation of global ecosystem services by R Costanza( 1997 )has attracted attention of the Chinese ecological researchers over the years. And many Chinese scientists have been using the methods to valuate the ecosystem services for forest, grassland and farmland ecosystems. However, it has been turned out that there are several shortcomings in direct adaptation of the methods, for instance, some ecosystem services have been insufficiently valuated or even ignored via using Costanza' s method. To fill this gap, we have, on the basis of Costanza' s method, developed a new method or ' unit value' based method for assessment of ecosystem services. Expert interviews with structured questionnaire were contacted in 2002 and 2007 respectively, and altogether 700 Chinese ecologists were involved in the interviews for testing the method. It has been found that the values of ecosystem services from expert knowledge based unit value method and biomass based method are comparative. Therefore, expert knowledge based assessment of ecosystem services could be used as a method for assessing ecosystem services with known land use areas, and a good result could be generated within a short period of time. However, for scientifically sound and concrete results, the spatial disparity of ecosystem services should be taken into account.
