中文摘要：

根据长时间序列中国植被指数数据集（GIMMS AVHRR NDVI）,分析了内蒙古神东矿区及周围20 km缓冲区1981-2006年归一化植被指数（Normalized Difference Vegetation Index,NDVI）的变化趋势,对神东矿区及缓冲区的NDVI均值进行了一元线性回归分析,并分析了神东矿区与缓冲区的NDVI均值的相关性。研究表明：神东矿区及缓冲区NDVI均值整体呈上升趋势,斜率分别为0.0047与0.0040,植被状况分别为中度改善与轻微改善;神东矿区及缓冲区NDVI值两组变量在0.01水平上显著相关,相关系数为0.971;神东矿区39个像元中轻微改善与中度改善各占35.90%与64.10%,矿区的植被状况呈向好趋势。

英文摘要：

According to the long time series of China vegetation index set（GIMMS AVHRR NDVI）,the change trends about Normalized Difference Vegetation Index（NDVI）in SHENDONG coalfield and its buffer area with a 20 km radius are analyzed in Inner Mongolia during the period of 1981-2006.The mean NDVI of SHENDONG coalfield,its buffer area and the NDVI of 39 pixels in SHENDONG coalfield are researched by Monadic linear regression analysis.And the correlation between the mean NDVI of SHENDONG coalfield and its buffer area are analyzed.The study shows that mean NDVI of SHENDONG coalfield and the buffer area are increasing overall,the slopes of the regression line are 0.0047 and 0.0040 respectively,and vegetation conditions are moderate improvement and slight improvement.Two variables are significantly correlated at the 0.01 level,the correlation coefficient is 0.971.39 pixels in SHENDONG coalfield have two trends,the slight improvement was 35.90%,the moderate improvement was 64.10%,and the vegetation condition in SHENDONG coalfield is in good trend.
