中文摘要	岷江上游是四川盆地和长江干流的重要生态屏障,其植被资源在汶川地震中遭受了严重破坏。以震前(2006年)和震后(2008年和2010年)的遥感影像数据为基础,研究了该区域植被在地震中的受损情况及灾后恢复状况。研究表明:受地震影响,岷江上游森林、灌木、草地和荒漠植被面积在2006~2008年分别下降23 124、 15 409、7 482和2 656hm~2,降幅依次为2.73%、2.53%、1.04%和4.12%,而沼泽面积变化不大;经过灾后恢复,森林、灌木、草地和荒漠植被面积在2008~2010年分别恢复12 104、21 283、10 554和2 847hm~2,分别占受损面积的52%、138%、141%和107%,而沼泽面积变化依然不大。植被的这些变化对区域的生态服务功能产生了深远影响。对合理开发利用区域资源、妥善处理经济建设和生态环境保护矛盾以及科学保障长江流域的生态安全都具有一定的指导意义。
英文摘要	The upper Minjiang River is an important ecological barrier of Sichuan Basin and the main stream of the Yangtze River.The vegetation resources in this region were damaged seriously by Wenchuan earthquake occurred on May 12,2008.Based on the remotely sensed images in 2006 (before the earthquake),2008 (early after the earthquake)and 2010 (recovery period after the earthquake),the vegetation damage situations during the disaster and its recovery status in the upper Minjiang River were studied.Results showed that,the forests,shrublands,grasslands and desert vegetation decreased by 23 124hm~2,15 409hm~2,7 482hm~2 and 2 656hm~2 during the period of 2006-2008,respectively,while they decreased by 2.73%,2.53%,1.04%and 4.12%,respectively;in contrast,the marsh area had no changes in this period.After 2years of ecological restoration(2008-2010),the forests,shrublands,grasslands and desert vegetation increased by 12 104hm~2,21 283hm~2,10 554hm~2 and 2 847hm~2,respectively,accounting for 52%,138%,141%and 107% of the damaged area,respectively;the marsh area still had no changes. The vegetation change had a very significant impact on regional ecosystem service functions.The present work provides guidance for reasonable utilization of regional resources,the proper treatment of the contradiction between the economical construction and environmental protection,and scientific protection of the ecological security in the Yangtze River Basin.
