The valuation of ecosystem services is highlighted in many eco-economics researches.However, there is relatively little elaboration of the temporal and spatial scales at which ecosystem services are given.Based on the new methods of evaluating ecosystem services,the framework to valuate ecosystem services is enhanced,i.e. to be added the spatial、temporal scales and benefit analysis on ecosystem services and benefit characters.The ecological services in Changdao island, Shandong province,are analyzed and the results are as follows:the changeable trend of ecosystem service values from 1994~2003 fluctuates and the trough is 7.4523×108￥ in 1999,wave crest 1.018186×109￥ in 2003；the values of aquatic product,food,fruit,nature conservation and recreation are calculated,their services are characterized with spatial scales,namely, the values of aquatic product, food and fruit are only important to people in Changdao island,recreation value to not only Changdao island but also provincial or national scale,nature conservation to national and international scale.Our analysis shows that communities or people at different spatial scales can have different interests in ecosystem services.The valuation of ecosystem services based on temporal, spatial and benefit characters supports the decisions-making by departments of ecosystem management.
