The Relationship of Vegetaion-derived Index and Site-measured Rice LAI
Leaf area index(LAI) is an important bio-physical parameter of paddy rice. The LAI will provide important information of the growth of paddy rice. In an effort to develop the quantitative relationships between field measured leaf area index and Vegetation-derived vegetation indices for paddy rice fields
we have measured the leaf area index of paddy rice at 10-day intervals at five sampling sites in Jiangning county
Jiangsu province during the rice growing season (July to October) of 1999
using a LI-COR LAI-2000 plant canopy analyser. After being transplanted in mid to late June
paddy rice LAI increased quickly and reached its plateau by early to mid August. Compared with the VGT sensor derived Normalized Difference Vegetation Index (NDVI)
we found that there were similar dynamics of LAI and Vegetation Index over the growing season of paddy rice in 1999.
