中文摘要	尾闾湖作为干旱区内陆河下游绿洲生态系统的重要组成部分,具有涵养水源、防风固沙等功能。然而近半个世纪以来,受气候变化和人类活动的影响,内陆河尾闾湖不断萎缩,湖区周围生态环境一度恶化,已严重威胁区域社会经济发展。为探究干旱区尾闾湖泊水域变化及其驱动因素,以新疆维吾尔自治区台特玛湖地区为例,选取1986-2019年间9期Landsat TM/OLI遥感影像,提取并分析了台特玛湖地区水域面积变化特征及其驱动因素。结果表明:34 a间研究区水域面积共增加了163.93 km~2,21世纪前水域零星分布在车尔臣河下游河道附近,进入21世纪以来主要分布在台特玛湖附近;研究区水域重心迁移经历了20世纪80年代末的快速向西转移、20世纪90年代期间的缓慢向东移动、20世纪90年代末至21世纪初的大幅度迅速东移和21世纪以来的波动向东移动4个过程;以塔里木河下游输水为界,输水前台特玛湖地区水域面积主要受区域自然因素综合作用,其中降水为主要驱动因素(r~2 =0.825),输水后,人为干预的输水过程是影响研究区水域面积变化的主导因素(r~2 =0.977)。随着不断向下游输水,台特玛湖地区生态环境持续恢复。为防止湖水丰盈,向东溢入罗布泊,有必要探究台特玛湖最大载水量,以期合理控制输水过程。
英文摘要	Terminal lake,which is an important part of oasis ecosystem in the lower reaches of inland river in arid region, has the functions of water conservation, wind prevention and sand fixation. However, for nearly half a century, the terminal lake of inland river has been shrinking under the influence of climate change and human activities, and the ecological environment around the lake has been deteriorating, which has seriously threatened the regional social development. In order to explore the changes and driving factors of the water area of the terminal lake in the arid region, this paper took the Taitema Lake region as an example, selected nine Landsat TM/OLI remote sensing images from 1986 to 2019, and extracted and analyzed the change characteristics and driving factors of the water area of the Taitema Lake region. The results showed that the water area of the study region increased by 163.93 km~2 in the past 34 years. In terms of spatial distribution, water area of the study region was scattered around the lower reaches of Qarqan River before the 21st century, and mainly distributed around Taitema Lake since the 21st century. The center of gravity of the water area in the study region experienced four processes: rapid westward shift in the late 1980s, slow eastward shift in the 1990s, rapid eastward shift in the late 1990s to early 2000s,and eastward shift in the fluctuation since the 21st century. Taking the water transport to the lower reaches of Tarim River as the boundary,the water area before water transport is mainly affected by the comprehensive effects of regional natural factors, with precipitation as the main driving factor (r~2 =0.825). After water transport, the water transport process with human intervention is the leading factor (r~2 =0.977) affecting the change of water area in the study region. With the continuous water transfer to the downstream of Tarim River, the ecological environment of Taitema Lake has been restored continuously. In order to prevent the lake from overflowing and spilling eastward into Lop Nor, it is necessary to explore the maximum water capacity of Taitema Lake so as to reasonably control the water transfer.
