摘　　要：利用2000—2008年250 m分辨率MODIS EVI数据,结合谐波分析、影像处理和多种统计方法分析长白山地区的植被覆盖年内和年际变化特征,并结合区划图和植被类型图对不同区域和不同植被类型的植被覆盖变化进行分析.分析显示:近9年长白山地区植被覆盖总体呈上升趋势,其中夏季上升最为显著;和龙林业局的植被覆盖较好,长白山保护区和白河林业局的植被覆盖处于较高的增长趋势,而朝鲜一侧的植被覆盖较差且增长缓慢;阔叶林和针阔混交林的植被覆盖高于针叶林、荒草地、沼泽地、高山岳桦林和高山苔原,其中高山岳桦林和高山苔原的植被覆盖正处于较快的增长趋势.Based on the MODIS EVI 250m resolution data, regional map and vegetation map, we analyzed the intra-annual and inter-annual variation of vegetation cover in Changbai Mountain by using the HANTS, imagery processing methods and statistical methods. Then further analyses were carried into different sub-regions and different vegetation types. The results show that： the vegetation variation trends are increased from 2000 to 2008 as a whole; the increase is particular obvious in summer; the EVI is much higher in the Helong Forestry Bureau and increased more rapidly in the Changbai Mountain National Reserve Bureau and Baihe Forestry Bureau than the nearby DPRK border area; though the EVI of the coniferous forest, grassland, marsh, betula ermanii forest and tundra are less than the broadleaf forest and mixed forest, the former grow faster than the later in vegetation cover.
