利用苏尼特草原地区1982—2006年NOAA AVHRR的NDVI数字遥感影像,以及1998-2007年逐旬的SPOT VAG-NDVI数据集,结合研究区域内苏尼特左旗、苏尼特右旗、朱日和、二连浩特4个气象站点的同期降水、气温数据,对植被盖度与不同组合方式的降水及气温数据进行了相关分析,探讨了植被盖度与气象因子的关系。结果表明：苏尼特草原生长季平均盖度、逐月盖度与降水呈正相关关系,与气温呈负相关关系,其中降水对盖度的影响存在着时滞及累积效应。

the NDVI product images of NOAA/AVHRR from 1982 to 2006 and the NDVI product images of SPOT VAG-NDVI from 1998 to 2007 were used to calculate vegetation coverage in Sunite steppe,and then correlation coefficients between vegetation coverage and climate factors were calculated. Climatic factors were combined into different patterns based on the observed time peri- ods and time lags for finding out the temporal responses of vegetation coverage to climate fluctuation or change. The main findings were as follows：The average vegetation coverage of growing season and monthly vegetation coverage have positive correlation with precipitation, and negative correlation with temperature. The impacts of precipitation on vegetation coverage show in time-delay and cumulative effects.
