CHENG Li-li1,HUANG Fang1,2,WANG Ping1(1 School of Urban and Environmental Sciences,Northeast Normal University,Changchun 130024,China)(2 International Institute for Geo-Information Science and Earth Observation(ITC),7500 AA,Enschede,the Netherlands)  
Using RS and GIS,based on the data of 1∶100 000 Landsat TM,the paper analyzes briefly land use/cover change in the ecotone of Songnen Plain from 1986 to 2000.Thus the dynamics of eco-environmental quality caused by LUCC was evaluated by using Costanza's method of evaluating the world's ecosystem service.The results indicate:during 1986-2000,the ecosystem service values in this area diminished due to land use change.The area of cultivated land,city and town land increased,while the area of woodland,pasture,water body and unuseland decreased.The increase ratio of cultivated land is up to 9.80%,city and town land construnction uses increase by 0.66%;the ratios of woodland,pasture,water body and unuseland are reduced by 1.10%,6.80%,1.20% and 1.20% respectively.Values of the ecotone in the west Songnen Plain's ecosystem service reduced 7000.15×104US$,in equal to 57891.24×104 RMB$causing the ecosysten service value lose of 9.74%.
