摘　　要：通过总结对比现有生态系统服务评估方法的优缺点,选用"功能当量"相对评估模型作为评估生态系统服务供给的方法。综合考虑生态系统服务的供给指标与需求指标对接程度,从两者可量化的角度出发,以"功能当量"相对评估模型为桥梁,构建生态系统服务供给-需求量化方法框架。最后通过案例分析对"功能当量"相对评估结果进行验证,且对研究区进行生态系统服务供给-需求量化评估,得出研究区服务供给量小于需求量的评估结果,为区域生态管理者和决策者提供参考。By summarizing advantages and disadvantages of the existing ecosystem services assessment methods,we select the relative assessment model of'functional equivalent'as a method to assess the ecosystem services supply. Considering the docking degree of ecosystem services supply indicator and demand indicator,and from the view of their quantization,the ecosystem services supply- demand methodological framework is built through the bridge of the relative assessment model of'functional equivalent'.Last,by means of verifying the relative assessment result of'functional equivalent'through case analysis and quantitatively evaluating ecosystem services supply- demand in the study area,it is concluded that the supply is less than demand in the study area,which provides a reference for regional ecological managers and decision- makers.
