摘要: 作物模拟模型从单点发展到区域应用时,模型中一些宏观资料的获取和参数的区域化方面出现困难,利用遥感技术将实现作物模拟模型的区域应用.文中综述了近年来遥感反演作物模型所需的地表生物物理参数的方法、利用遥感信息直接获取生物量的途径和遥感信息与作物模拟模型之间时空匹配问题等方面的研究概况,重点介绍了利用遥感技术实现作物模拟模型区域应用的3种解决方案(强迫型、调控型和验证型)及其研究进展,并讨论了目前存在的问题和今后研究的方向.

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.

Key words: Crop simulation model, Application in regional scale, Remote sensing technique
