中文摘要：

随着社会经济的发展,人类对生态系统的干扰导致多种生态服务退化或消失.生态系统服务流对生态系统服务的输送、转化和维持有重要作用,并成为相关研究的新兴方向之一.本文在对生态系统服务流进行分类的基础上,分析了生态系统服务传递的载体,初步探讨生态系统服务流的形成机制,包括服务流的形成、属性、尺度特征、定量化及其制图等.同时,对生态系统服务流的成本效应,如输送成本、转化成本、使用成本和成本相对性等进行尝试性分析,旨在分析生态系统服务流传递过程中的成本耗散.生态系统服务流研究一定程度上解决了生态系统服务价值评估的“双重核算”问题,使人类准确识别生态系统服务供给和消费热点区域,有利于生态系统服务在传递过程中达到效益最大化,对提出科学合理的生态补偿有重要意义.

英文摘要：

ecosystem With the development of social economy, human disturbance has resulted in a variety service degradation or disappearance. Ecosystem services flow plays an important role of in delivery, transformation and maintenance of ecosystem services, and becomes one of the new re- search directions. In this paper, based on the classification of ecosystem services flow, we analyzed ecosystem service delivery carrier, and investigated the mechanism of ecosystem service flow, inclu- ding the information, property, scale features, quantification and cartography. Moreover, a tentative analysis on cost-effective of ecosystem services flow （ such as transportation costs, conversion costs, usage costs and cost of relativity） was made to analyze the consumption cost in ecosystem services flow process. It aimed to analyze dissipation cost in ecosystem services flow process. To a certain ex- tent, the study of ecosystem service flow solved the problem of ＂double counting＂ in ecosystem services valuation, which could make a contribution for the sake of recognizing hot supply and con- sumption spots of ecosystem services. In addition, it would be conducive to maximizing the ecosys- tem service benefits in the transmission process and putting forward scientific and reasonable ecolog- ical compensation.
