| 摘 要： | 植被覆盖状况是评估生态环境的重要指标。利用GIMMS数据集的8 km分辨率的NDVI数据和气候数据,对内蒙古地区1982—2000年植被覆盖变化进行了分析,并评估了降水与该地区植被的相关关系,在此基础上探讨了人类活动对内蒙古地区植被覆盖变化的影响。研究中采用了相关分析和残差分析,结果表明,在过去19年中内蒙古地区植被NDVI总体上呈轻微上升趋势,且存在着显著的空间差异。同时内蒙古地区植被NDVI与降水有很好的相关性,植被受降水的影响较大。此外,人类活动对内蒙古一些地区的植被变化也起到了建设或破坏的作用。

| Abstract: | Vegetation cover is a good indicator for evaluating terrestrial environment.To analyze the vegetation dynamic changes in Inner Mongolia and its relationship with climate change and human activities from 1982 to 2000,major methods of correlation analysis and residual analysis are employed using NASA GIMMS Normal Difference Vegetation Index(NDVI) time series data set and climatic data.The results show that there is little increase of vegetation cover during the past 19 years and there exists remarkable differ... |
