摘　　要：以2007-2015年4-9月EOS/MODIS卫星数据为基本数据源,并结合气象观测数据,采用3S技术,对天山北坡经济带各县（市）的湿润指数、水覆盖指数、植被覆盖指数以及农田（干旱）灾害指数进行了研究,并通过农田生态质量综合评价指数分析该地区的生态质量状况。结果表明：2007-2015年天山北坡经济带各县（市）的农田生态质量综合评价综合指数分别在32.18-37.72之间,近9年的农田生态质量状况没有发生明显的变化,但总体趋势是逐渐增加的,说明生态环境有所好转,本研究可为有关部门开展生态建设规划和环境保护提供科学决策依据。Using the satellite data of EO-S/MODIS during 2007 to 2015 （April to September）as the basic data sources, and combined with meteorological observation data, by using 3S technology ,farmland economic belt in north slope of Tiansban Mountains were studied, selecting the four indexes such as moisture index ,vegetation cover index ,water coverage index and disaster index.The ecological quality of farmland in the area was analyzed through comprehensive index. The results showed that：During 2007 to 2015 ,economic belt in north slope of Tianshan Mountains counties （cities）of the ecological quality of farmland comprehensive evaluation index between 32.18 and 37.72, nearly nine years of farmland ecological quality of no obvious change ,but the overall trend increased ,indicating that the ecological environment is improved. This study may be relevant departments to carry out ecological construction and environmental protection plan to provide a scientific basis for decision making.
