In this study, the BEPS (boreal ecosystem productivity simulator) model combining the Moderate Resolution Imaging Spectroradiometer (MODIS) multi-temporal satellite remote sensing data such as leaf area index (LAI) and land cover types data were used to simulate the rapeseed in Hubei province. Interpolating the 17 agricultural meteorological stations data of rapeseed in the study area, and based on the relevant data of rapeseed crop growth physiological and the process of rapeseed growth simulation technology, the estimating biomass of rapeseed was performed in a regional scale. This paper validated the result of simulated BEPS model and actual statistical data of rapeseed yield. The results showed that the model simulated values are agreed with the actual statistics yield of rapeseed, the correlation coefficient (
) is up to 0.877 with 0.01significant level. The simulated value with absolute mean square error (RMSE) of statistics is 416 kg/hm
. It determined that the BEPS process-based model integrated with MODIS satellite data can estimate the rapeseed yield in a regional scale.
