比值植被指数 meaning in Chinese

ratio vegetation index

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。
