生态系统服务价值在土地利用变化研究中的应用:瓶颈和展望

Application of ecosystem service value in land use change research:Bottlenecks and prospects

近些年,将生态系统服务价值运用于土地利用变化研究成为世界知名期刊上的重要话题,然而政策制定者在实践中却很少采纳这些研究成果.本文通过大量文献阅读,归纳出制约生态系统服务价值运用于土地管理实践的三大瓶颈,分别是价值测量的困难性、驱动因素的复合性和评价标准的片面性,并提出了相应的解决路径.最后,对我国未来的研究方向进行展望,认为基于生态系统服务价值对土地利用变化进行研究,更适合采用小尺度区域的比较分析方法,尤其应关注自然生态资源及其价值的过度性损失.

In recent years,the application of ecosystem service value in land use change research is a hot topic in many famous international journals.However,policy makers are seldom taking into account the achievements of the related studies in practice.This paper summarized the three main bottlenecks in applying ecosystem service value in land management practices,i.e.,the difficulty in measuring the service values,the complexity of driving factors,and the bias of evaluation criteria.Some solutions on the bottlenecks were provided,and the future research directions in China were prospected.It was suggested that in the studies of land use change based on ecosystem service value,it would be more appropriate to adopt comparative analysis method in small scale case studies,especially focusing on the natural ecological resources and the excessive loss of their values.
