| 摘 要： | 根据2004~2006年的遥感MODIS-NDVI和地面农业气象观测数据,分析了NDVI时间序列的变化与贵州中部农作物生长发育及长势的规律。结果表明:遥感植被指数与秋粮作物生育期和长势存在较好的相关性,NDVI=0.7和ND-VI>0.75对应了黔中水稻和玉米的关键生育期及对温度条件要求最敏感的时期。利用卫星资料得出的植被指数,可用于建立秋粮作物产量评估模型。

| Abstract: | The results from analyzing the relationship between NDVI's time variation and crops' growth development and vigour according to MODIS-NDVI and agro-meteorological observation data in 2004~2006 in Guizhou,showed that there was a good correlation between the vegetation index and crops' growth development and vigour,and that when NDVI was 0.7 and NDVI was above 0.75,the growth of rice and maize was in the key growth period and the most sensitive period to temperature condition.The crops'yield monitoring model can be built by using the vegetation index from satellite photographs. |
