Correlation analysis of simulated MODIS vegetation indices and rice leaf area index and leaf chlorophyll content
MODIS植被指数与水稻叶面积指数及叶片叶绿素含量相关性研究

This paper studied the correlations between rice leaf area index(LAI),leaf chlorophyll content(CHL.C),hyper-spectral data,normalized difference vegetation index(NDVI),enhanced vegetation index(EVI),and red-edge position(REP).The results showed that LAI had a close correlation with visible and NIR bands,and CHL.C had the highest correlation with red band.A strong non-linear correlation was found between the LAI and REP of two rice varieties.For common rice,REP,EVI and NDVI were well related with LAI,but for hybrid rice,REP and EVI were more sensitive than NDVI to LAI.In 2003,REP,EVI and NDVI were well related with CHL.C.
