中文摘要	以4 期Landsat 遥感影像为基础,结合两期土地利用图及历年实地考察资料,分析了1977-2002 年间新疆于田的景观变化特征. 研究发现,于田平原与荒漠区环境退化严重,荒漠增加而交错带减少,高生态级别的高覆盖度草地锐减;绿洲在稳定增长,以绿洲为中心的核心区生态环境质量却明显退化,但天然绿洲整体变化不明显,波动小且变化恢复较快;生态的主要退化期为20 世纪70-80 年代,此后趋于好转,1999 年以后好转明显;人工绿洲的开发只是明显影响了绿洲近缘景观,对远缘影响较弱
英文摘要	Based on remote sensing imagesland use maps and field survey datathe landscape change during 1977-2002in Yutian County a typical arid region in Xinjiang of China was researched. The results were as follows. The ecological environment in oasis and desert region had in general degraded seriouslydesert area increased and oasis-desert ecotone decreased and the grassland with high coverage decreased fast. The oasis expanded stably but the ecological environment in its core area had degraded significantly notwithstanding the natural oasis didnt change significantly overall. The degradation of ecological environment took mainly during1970s and1980s.It can be seen that the development of artificial oasis only had changed the near landscapes its effect to distant landscapes was weak
