摘要
利用 198 3～ 1992年 NOAA/AVHRR逐月的归一化植被指数 (N DVI)资料和中国国家气象局全国 16 0个基本标准气象站的月均温和降雨数据 ,探讨气温、降水对中国植被 N DVI动态变化驱动作用。首先计算了 N DVI与气温、降水偏相关和复相关系数 ,研究了中国植被 N DVI变化的气候因子驱动的区域分异规律。并据此 ,对中国植被 N DVI变化的气候因子驱动进行了分区 ,共分出 4个一级区 ,6个二级区和 14个三级区 ,进一步表明了中国植被 N
Monthly digital NOAA/AVHRR NDVI images with 8 km spatial resolution and monthly temperature and precipitation data were obtained for 160 standard observatories across China from 1983 to 1992. The relationships among these factors were analyzed for trends, and rules for the regional distribution of variation in NDVI based on the correlation between NDVI with temperature and precipitation were developed. The scheme of regionalization of NDVI change by climate factors developed includes 4 first class regions, 6 second class regions and 14 third class regions, and clearly indicates regional variation in NDVI in China.
