摘　　要：利用长时间序列的Landsat数据,获得了泰山地区近10 a(2006~2015)地表植被的总体变化趋势。研究结果显示,研究区45%的地区呈显著性绿化趋势,29%的地区呈显著性褐变趋势,26%的地区无显著性变化。不同植被类型之间的绿度趋势变化具有一定差异性,农用地绿化、褐变以及无显著变化趋势占比相当,但变化值较低,总体上呈无显著变化趋势;林地和草地主要呈轻微绿化趋势;非植被类型绿化趋势无显著变化,褐变趋势较弱。In this paper,we utilized the long time series Landsat to obtain the total variation trend of surface vegetation in Tai Mountain Area from 2006 to 2015.The results indicate that the significantly greening areas account for 47%of the whole area,the significantly browning areas account for 18%,and the other areas have no significant changes.The greenness trends among different vegetation types have some discrepancy.The greenness trend of farmland mainly distributes in low value areas.The areas of forest and grass mainly show slight greening trend and the non-vegetation areas mainly show greening trend.
