摘    要:对中国160个气象站10a的连续AVHRR NDVI数据、气象观测数据进行相关分析,并结合植被覆盖类型资料深入探讨了AVHRR NDVI/气温和AVHRR NDVI/降水相关系数的地区差异及其随植被类型变化规律。研究结果表明,对中国的大部分地区,气温对植被的影响超过降水。就自然植被而言,其对降水的敏感性趋势为草本植被大于灌木植被,灌木植被大于乔木植被。就农作物而言,降水影响取决于耕作制度、作物种类

关 键 词:NDVI  气候因子  相关性  植被

Abstract:Based on 10 year monthly average AVHRR NDVI data and weather records collected from 160 stations all over China,the relationship between AVHRR NDVI and the climate factors including air temperature and rainfall was analyzed.The results showed significant correlation between the NDVI and the two climate factors and temperature was more influential than rainfall on the NDVI.It was also demonstrated that for natural vegetation,the NDNI/rainfall correlation coefficients decreased in an order of grass,shrub,and forest.The correlation coefficients of cultural land depended on a number of factors including agricultural practice,type of crops,seasonal variation in precipitation,especially irrigation pattern.
Keywords:NDVI  climate factor  correlation  vegetation
