| 摘 要： | 植被动态变化对全球能量循环和物质循环具有重要的影响,对植被覆盖变化的研究在全球变化研究中具有重要的意义。为了阐明近8年来中国植被覆盖的整体状况,利用SPOT4-VEGETATION/NDVI时间序列数据,以各个像元的线形回归的相关系数及其显著性水平为植被覆盖活动的指标,对我国1998~2005年8年间的植被覆盖状况及其年际变化进行研究分析。

| Abstract: | Vegetation coverage change are seriously affected energy cycle and material cycle of the world,so study on vegetation coverage change is important to global change research.This paper described overall situation of vegetation coverage change in China in recently 8 years,and analized the status and interannual variations of vegetation coverage during 1998 to 2005 by taking correlation coefficient of line regression and salient features as indexes based on SPOT4-VEGETATION/NDVI time series data. |

| Keywords: | remote sensing vegetation coverage normalized vegetation index dynamic changes line regression |
