摘　　要：应用遥感和GIS技术,以1992年和2006年两期LandsatTM影像解译数据为基础,分析图们江流域14a土地利用变化情况,并计算由此导致的生态系统服务价值变化。结果表明:14a间,图们江流域土地利用发生显著的变化;旱田、水田和建筑用地增加;林地、草地、水域、湿地和未利用土地在减少;ESV由1992年的472.43×108元减少到2006年的446.39×108元,年均递减率达0.39%;生态系统单项服务功能价值中,食物生产呈增加趋势,增加0.24×108元,主要由耕地面积增加,以及气候调节、水源涵养、生物多样性保护等其余功能均呈减少趋势所致。因此,应须采取有效措施,维护该区生态环境健康发展。Based on the data of Landsat TM in the years 1992 and 2006,the paper,by using RS and GIS,analyzed land use change in Tumen River region in the 14 years and also calculated the change of ecosystem services value which resulted from it.The results show that great changes took place to the land utilization in Tumen River region from 1992 to 2006,which included the increase of dry farmland,paddy field and building lots and the decrease of woodland,grassland,water area and wetland.At the same time,ESV declined from $472.43×108 in 1996 to $446.39×108 in 2006 with an average annual lapse rate of 0.39%.In all the functions of ecosystem services value,the food production function increased by $0.24×108 mainly due to the increase of agricultural acreage and other functions like the climate regulation,the conservation of water supply and the protection of biodiversity decreased.Therefore,effective measures should be taken to maintain healthy development of environment in the area.
