摘要
Abstract
In order to use the Normalized Difference Vegetation Index (NDVI)effectively for maize production prediction ,taking Zhaodong city of Heilongjiang province as study area ,HJ1B remote sensing data and the field measured data in maize heading stage were used to predict maize yield .Combined with radiation calibration ,at-mospheric correction ,geometric correction and the spectral reflectance ,the NDVI was calculated to make curve-fitting with the field measured yield data .The results showed that the best correlation between maize NDVI in heading stage and yield was quadratic polynomial and the accuracy was 86% ,the maize yield in 2011 was pre-dict to generate the remote sensing thematic map compared with measured results .Therefore ,the determination of NDVI had a certain relevance with production .关键词
