摘　　要：为了探究和林格尔县植被覆盖度的变化特征,基于Landsat TM/OLI影像数据,采用像元二分法和趋势分析法从时间和空间尺度上分析了研究区的植被覆盖度年际变化和空间分布特征。结果表明:研究区的年平均植被覆盖度总体呈上升趋势;高植被覆盖度分布在西北部地区,大部分地区为低,中低植被覆盖度。To explore the changing characteristics of vegetation coverage in Helinger County, the interannual variation and spatial distribution characteristics of vegetation coverage in the study area were analyzed from the temporal and spatial scale based on Landsat TM/OLI image data. The results show that the annual average vegetation coverage in the study area is increasing;high vegetation coverage is distributed in the northwest, with low and low in most areas.
