中文摘要	根据于田绿洲1991、 2001和2011年的Landsat TM/ETM+影像数据,利用RS和GIS技术,对于田绿洲土地利用/覆被类型时空变化特征进行深入分析.结果表明:在1991-2011年间,耕地面积净减14.41%,主要转为林地和草地,表明近20 a来农业产业结构有了很大调整,退耕还林还草政策逐渐生效;水体面积净增64.86%,主要来自林地、草地和未利用地,表明为保证绿洲灌区合理利用水资源,进一步完善了水利基础设施;林地面积净减20.28%,可见忽略森林的生态功能,林地面积的逐年减少无疑会对当地的生态环境产生影响;草地面积净增26.07%,主要来自耕地、林地和未利用地,表明退耕还草政策和遏制破坏草地盲目开垦,使有效的增加草地面积;建设用地面积净增440.21%,主要来自耕地、林地和未利用地,表明随着人口的迅速增长和社会经济的快速发展,建设用地面积日益扩展;未利用地面积净减4.75%,主要转为耕地、草地和水域,表明盲目的开垦仍然存在,使严重破坏的天然植被,本来就极为脆弱的生态环境雪上加霜,同时水资源的短缺,开垦后因无水灌溉而弃耕撂荒.
英文摘要	In this paper, based on Landsat TM/ETM+ images of 1991, 2001 and 2011, the spatio-temporal characteristics of land use/cover changes in Yutian oasis were analyzed by using RS and GIS technology. It is found that from 1991 to 2011, cultivated land had decreased 14.41%, most of them had changed to forest and grass land, showing that 20 years` adjustment of agricultural structure and reforestation policy had gradually taken effect; water body had increased 64.86%, most of them had came from previous forest, grass land and unused land, which had ensured the rational use of water resources in irrigated oases and to further improved the water infrastructure; forest land had decreased 20.28%, demonstrating that decreasing forest area will undoubtedly impact the local ecological environment, if the ecological functions of forest were ignored; grass land had increased 26.07%, most of them came from arable land, demonstrating that the forest land and unused land, grain for green policies had curbed the destruction of grasslands by blind reclamation, and helped effective increase of grassland area; construction land had increased 440.21%, mainly came from former arable land, forest land and unused land, meaning that the construction area expanded with the population explosion and rapid social and economic development; unused land had decreased 4.75%, mainly changed to decreased arable, grass land and water body, which means blind reclamation was persisted, which severely damaged the natural vegetation cover, made the extremely fragile ecological environment even worse, and because of shortage of water resources, reclaiming had been abandoned.
