摘要
基于新疆维吾尔自治区察布查尔锡伯自治县2000、2006和2013年的Landsat遥感影像,利用ENVI5.0和Arc GIS9.3软件对其进行辐射定标、大气校正、植被覆盖度提取,对比了察布查尔锡伯自治县14年来的植被动态变化,分析了其变化趋势,并探讨了植被覆盖度变化驱动机制。结果表明,2000-2013年,察布查尔锡伯自治县植被覆盖度明显增加,高植被覆盖度面积也明显扩张,尤其是人为退耕还林、退耕还草增长比较明显。
Based on landsat remote sensing image of Qapqal Xibo autonomous country in Xinjiang Uygur autonomous region in 2000,2006 and 2013,using Arc GIS9.3 and ENVI 5.0 software for radiometric calibration,atmospheric correction and vegetation coverage extraction,the study was carried out to contrast the dynamic changes and trend of vegetation coverage, and its driving mechanism were discussed. The results showed that vegetation coverage of Qapqal Xibo autonomous country had significantly increased from 2000 to 2013,and the high vegetation coverage area also had the obvious expansion, especially for returning farmland to forest and grassland.
