摘要
文章使用NOAA17／AVHRR数据，采用归一化差值植被指数（NDVI）模型，对2006年3月-2007年2月若尔盖及周边地区进行计算和分析得出，NDVI在7月最大，12月最小；结合降水量和气温的年变化，分析了NDVI的季节特点和变化规律的气候基础。
In this paper, based on NOAA17/AVHRR data, Normalized Difference Vegetation Index （NDVI） model is calculated and analyzed for Ruoergai and its surrounding area from March 2006 to February 2007. It concludes that the maximum and minimum NDVI appeared in July and December respectively. The climate basis for seasonal features and change rules based on annual precipitation and temperature changes are analyzed.
