Examples
- The correlation analyses were conducted for the rations between the vegetation indices and the sampled grass yield data which were taken as the grassland biomass quotas . the results indicated that there are quite high correlations between the vegetation indices and the grassland yield data . among them the rvi has the highest correlation coefficient , ndvi in the next , and then successively tvi , msavi , infrared index , savi , gvi , dvi and w vi , but bvi has the lowest correlation coefficient that there is a negative correlation coefficient between bvi and the biomass
对各种常用植被指数和草地生物量进行相关分析，由分析结果得出，比值植被指数( rvi )与草地生物量的相关性最高，相关系数达到0 . 885 ，其次为ndvi ，然后依次为tvi 、 msavi 、红外指数、 savi 、 gvi 、 dvi和wvi ，而bvi与草地植被生物量呈负相关关系，且相关性最低，总的来说，遥感植被指数和草地生物量具有较好的相关关系，因而，利用植被指数来建立草地生物量监测模型是可行的。
