摘要:

通过利用1992~1996年NOAA/AVHRR逐旬的归一化植被指数(NDVI)数据和阜康气候、水文资料,分别对绿洲和荒漠进行了NDVI与气候、水文因子间的相关分析,得出了一些初步结论:绿洲与荒漠NDVI具有不同的季节变化规律;与绿洲NDVI相关显著的因子依次为气温、地下水位和降水,

Abstract:

The interactions between vegetation and climate are always an important domain in ecological research. NDVI(Normalized difference vegetation index)is an important index that reflects the radiation-absorbing characteristic of vegetation and the climatic st
