title: [A review on research of implement application for crop simulation model in regional scale by using remote sensing technology].
abstract: When applying crop simulation model developed from plot-scale level to regional scale, some challenges such as acquirement of some broader spatial data and regionalization of parameters will arise, while satellite can monitor crop growth status by remote sensing. Therefore, regional application of crop simulation model will be implement by remote sensing technique. In this paper, some research advances are reviewed, which include the methods of biophysical parameters retrieved from remote sensing data for crop model, the approach of biomass obtained by remote sensing data directly, and the means of matching temporal and spatial resolution between remote sensing data and crop model input. Three solutions (forcing, recalibration and validation) to the application of crop model in region scale by using remote sensing technique were emphasized, and the current problem and future research orientation in this filed were discussed in brief.
