为了在区域尺度上评价水稻生产和管理，提出了一种结合遥感的模拟模型。本研究旨在开发一种用于遥感的模拟模型(SIMRIW-RS)，以评估区域尺度上水稻生产的田间差异。该模型是在水稻天气关系模拟模型SIMRIW及其衍生模型的基础上开发的。该模型由水分收支、氮素吸收、物候发育、叶面积指数(LAI)生长、干物质生产和产量形成6个部分组成，具有2个代表性田间参数和5个代表性品种参数。用前人的田间试验数据确定的参数似乎反映了田间和品种的特性，并用该模型很好地解释了田间和品种间水稻生长和产量的差异。最后讨论了该模型在区域尺度上的遥感应用。
To evaluate rice production and management on a regional scale, a simulation model combined with remote-sensing is recommended. This study aimed to develop a simulation model for use with remote-sensing (SIMRIW-RS) to evaluate the field-to-field variation in rice production on a regional scale. This model was developed based on a simulation model for rice weather relations called SIMRIW and its derived models. The model consists of 6 components (water budget, nitrogen uptake, phenological development, leaf area index (LAI) growth, dry matter production and yield formation) and has 2 representative field parameters and 5 representative cultivar parameters. The parameters that were determined with the data from previous field studies seemed to be reflected with field and cultivar characteristics, and differences in the rice growth and production among the fields and cultivars were well explained by the model. The application of the model on a regional scale using remote sensing is discussed.
