【摘要】 本文在遥感和地理信息系统技术支持下,以1986~2000年的1∶100 000 LandsatTM图像解译数据为基础,全面分析了1986~2000年该区土地利用/覆被的动态变化特征,运用Cost-anza等人对全球生态系统服务价值的计算方法,对松嫩平原西部生态脆弱区土地利用/土地覆被变化(LUCC)引起的生态环境质量变化进行了评估。计算结果表明:在1986~2000年间,由于土地利用面积的变化而使该地区的生态系统的生态价值减少,松嫩平原西部耕地和城乡建设用地有所增加,其他林地、草地、水域和未利用地的面积均减少。耕地面积增加的比例为9.80%、城乡建设用地增加0.66%;林地、草地、水域和未利用地面积减少的比例分别为1.10%、6.80%、1.20%和1.20%,15年的时间里松嫩平原西部生态脆弱区生态系统总价值减少7 000.15×104美元,相当于人民币57 891.24×104元,使生态系统服务价值损失9.74%。更多还原

【Abstract】 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%.更多还原
