摘　　要：在颁布的森林生态系统服务功能评估标准的框架下,采用森林生态系统定位研究网络(CFERN)台站多年连续观测数据和2007年辽宁省森林资源清查数据及公共数据,对本溪市和大连市森林生态服务功能的物质量和价值量进行比较分析。结果表明:本溪市和大连市的森林生态系统服务功能的总价值分别为280.30、205.82亿元·a-1;按不同优势树种(组)划分的林分类型在两市的森林生态系统服务功能中发挥的作用均有差别;针叶树种的林分在大连市发挥的生态服务功能价值要优于本溪市,而阔叶树种则相反。A detailed evaluation on the material quantity and services value of forest ecosystems in Benxi City and Dalian City was made by means of continuous observational data from the Station affiliated to Chinese Forest Ecosystem Research Network（CFERN） and forest resource inventory data and public data according to the framework of the promulgated evaluation criteria implemented in forest ecosystem services.Results showed that the total annual value of the ecosystem services were 28.030 billion RMB yuan for Benxi City and 20.582 billion RMB yuan for Dalian City.The role of stand type classified by different dominant tree species in services value of forest ecosystems was different in Benxi and Dalian.The services value of coniferous trees was higher in Dalian than in Benxi,and that of broad-leaved trees was opposite.
