【摘要】 中国科学院新疆生态与地理研究所利用MODIS卫星接收站接收的MODIS数据进行了艾比湖湖水水面动态监测 ,并连续监测了湖面西北 10 7km2 裸露湖底的水面恢复情况 ,佐证了覆盖该裸露区所需的理论入湖水量。结合塔里木河应急生态放水工程 ,利用归一化植被指数提取结果进行了生态放水引起的植被恢复状况监测 ,利用连续MODIS数据进行了台特玛湖水面变化的监测 ,证实了应急输水的生态保护效果是十分显著的。显示了中尺度分辨率MODIS数据在新疆生态环境建设中具有很强的应用前景。更多还原

【Abstract】 The paper introduces the characteristics of the MODIS data receiving station of Xinjiang Institute of Ecology and Geography,CAS. The change of the water area of Ebinur Lake is termly estimated by using the MODIS data. The monitored results during the period from November 2001 to November 2002 show that the water area of the Ebinur Lake has been continuously enlarged and over 800 km 2 in average,and the dried-up lake bottom in the northwestern part of the lacustrine area has been covered with water. The effects of drawing off stream water for saving the ecology in the lower reaches of Tarim River have been monitored by using the MODIS data from 2002 also. The monitored results by using the MODIS data show that the Taitema Lake was about 3 times of that after the third time of drawing off stream water. According to the monitored results of the monthly NDVI,the area of the regenerated natural vegetation was obviously larger than that in 2001,and the effects of the project of urgently drawing off stream water is very significant in protecting the ecology.更多还原
