| 摘 要： | 本文利用多期基础性地理国情监测正射影像成果,结合气象、统计等专题资料,借助遥感监测优势、测绘地理信息技术,对2012年、2016年、2017年沙漠范围及内部的绿洲变化情况进行了监测分析。结果表明:2012-2017年塔克拉玛干沙漠面积总体增加,增加幅度0.25%;占沙漠7.6%左右的绿洲,总体增加,增加幅度为4.79%,主要集中于沙漠南缘,沿河流分布、大小不一、彼此隔离;沙漠及内部绿洲变化形式复杂,不同区域变化趋势各不相同。整体来说,各县市区域内均以绿洲扩张、沙漠退缩为主,塔克拉玛干沙漠覆盖的各县市相较以往,生态环境有不同程度的改善。

| Abstract: | Depend on remote sensing monitoring advantages,surveying and mapping geographic information technology,this paper uses multi-period basic geographical conditions to monitor orthophoto results,combined with meteorological,statistical and other thematic data,monitors and analyzes the changes in the desert range and internal oasis in 2012,2016 and 2017. Results show that: From 2012 to 2017,the total area of the Taklimakan Desert increased,approximately 0.25%;The oasis,which accounts for about 7.6% of the desert,approximately 4.79% increased;Oasis is mainly concentrated in the southern margin of the desert,distributed along rivers,varying in size and isolated from each other;Deserts and internal oases have complex forms of change,and trends in different regions vary. On the whole,the counties and cities are expanding in the oasis,and the desert is retreating. Compared to the past,the ecological environment has improved to varying degrees in the counties and cities covered by the Taklimakan Desert. |
