摘　　要：选取沂蒙山区1999年和2003年两个不同时期的TM影像,通过归一化植被指数和植被覆盖度像元分解模型,研究了1999-2003年沂蒙山区植被覆盖度的动态变化.研究表明,在此期间沂蒙山区植被状况在一定程度上有所改善.The vegetation variation can reflect the exhibition shrinking of vegetation coverage area well.Therefore, we select the TM images of two different periods：the year of 1999 and 2003 in Yimeng mountain area,and study the vegetation coverage dynamic change of this area from 1999 to 2003 by using the normalized difference vegetation index and pixel decomposition model of vegetation coverage.The research shows that the vegetation status of Yimeng mountain area has improved to a certain extent during this period.
