中文摘要	[目的]揭示焉耆盆地1964~2007a景观变化规律,为合理开发利用绿洲水土资源和生态安全评价提供依据. [方法]根据焉耆盆地1964~2007a5期遥感影像解译数据,进行景观变化分析. [结果]耕地从1964a占整个研究区面积的8.96%到2007a的44.69%,成为焉耆盆地最主要的景观;1964~2007a,草地面积减少了94.51%,主要转变为耕地;水域面积减小约1/3,遥感影像上表现出河面、湖面的萎缩;林地景观曾一度消失,近7a在退耕还林政策推动下再次出现;湿地景观相对稳定. 研究期内,城乡、工矿建筑用地面积占整个研究区面积比例从0.04%上升到2.90%,但仍然属于非优势景观;未利用土地位于其他景观外围,2000~2007a未利用地在博斯腾湖大湖东北角处有了一定的增加. [结论]近半个世纪以来,随着人类对焉耆盆地自然景观干扰强度的增加,研究区内景观多样性水平降低,异质化程度降低,土地利用向单一化方向发展,土地开发已达极限,生态安全面临威胁
英文摘要	[Objective]To show the change discipline of landscape pattern of Yanqi basin and to provide a foundation for the soil and water resources utilization of oasis and the evaluation of ecological security.[Method]Based on the data interpreted from 5 remote sensing images in different period from 1964 to 2007, the landscape changes were analyzed.[Result]The area of cultivated land increased from 8.96% to 44.69% from 1964 to 2007, and became the main landscape in the research area. Grassland area had decreased by 94.51% in 2007 compared with that in 1964,it mainly is because grassland was transformed to cultivated land gradually. The water area had decreased by 1/3, Forest and, river area and lake area in remote sensing had disappeared but they had appeared again due to the conversing farmland to forest and grass policy of the government in the last 7 years. The city and countryside building land increased from 0.04% to 2.90% in 44 years, but it still belongs to the non-preponderant landscape yet.but the area of the non-used land surrounded the whole research area increased in certain extent in the north east of Bositeng lake from 2000 to 2007.[Conclusion]for nearly half a century, the interference intensity caused by human with the natural landscape increased while the diversity of the landscape has decreased, and the land using has developed to the direction of unitery in the research area, the land exploitation had researched the ultimate and caused threaten to the ecological safety
