| 摘 要： | 本文以1989年和2000年TM影像为基础,结合部分统计资料,分析了准噶尔盆地西南缘沙湾-石河子-玛纳斯人工绿洲近20年的变化特点。分析结果表明:该研究区人工绿洲面积增加显著,由1989的6077.62km2增至2000年的6995.02km2,且主要增长期为1995年以后,1998-2002年增长尤为明显;绿洲内部存在一定程度的弃荒现象,1989-2000年间有365.29km2农用地被荒弃;绿洲的增长以外延式增长为主,开发原有绿洲内部空地为辅;同时,北部莫索湾绿洲土地盐碱化现象明显。

| Abstract: | Based on the TM images of 1989 and 2000, integrated some statistical data, nearly 20 years of change characteristic of the artificial oasis of Shawan - Shihez - Manas which locates in the southwest Junggar Basin were analyzed, the conclusion is the artificial oasis area increased from 6077.62km^2 in 1989 to 6995.02km^2 in 2000, the main growth period was after 1995, and during 1998 -2002 the growth was especially quick; There was a certain degree of abandoned phenomenon in the oasis, 365.29km^2 of agriculture land was deserted during 1989 -2000; The oasis growth primarily was along the oasis sides; Simultaneously the land salinization phenomenon in north Mosouwan oasis was evident. |
