中文摘要	利用2001~2010年间MODIS NDVI数据、同期气象数据和MODIS土地覆盖分类产品,探讨蒙古高原植被覆盖变化趋势及其对气温和降水量的季节响应特征。结果表明,10 a来,蒙古高原植被覆盖度呈增加趋势和呈下降趋势的面积基本持平;春季和夏季植被覆盖度呈下降趋势,而秋季呈上升趋势,降水量是最主要的影响因子;在秋季5种植被类型均呈增加趋势,而在春季和夏季不同植被类型的增减趋势因植被类型而异。
英文摘要	The change trend of vegetation cover in Mongolian plateau and its response to seasonal temperature and precipitation were analyzed by employing MODIS NDVI in 2001-2010, composed by 16 day maximum value synchronous climate variables and MODIS land cover product MCD12Q1. The result indicated that the area of vegetation cover increased which was similar to that of vegetation cover decreased, reaching 43.75% and 42.22% of the total area of Mongolian plateau, respectively. In recent 10 years, the vegetation cover decreased in spring and summer, while increased in autumn. The correlation analysis between seasonal NDVI and corresponding seasonal climate factors showed that the correlativity between NDVI and precipitation was significant in spring and summer (P=0.02 in spring, P=0.003 in summer), and the correlation coefficient between NDVI and precipitation in autumn also reached 90% confidence level, indicating that precipitation was a main factor of influencing vegetation cover changes in Mongolian plateau. It was found that five different vegetation types experienced increasing trend in autumn, vegetation changes in Gobi-desert experienced increasing trend in all 3 seasons.NDVI of forest, grassland and shrub decreased in spring and summer, while farmland decreased in spring and increased in summer.
