抽象的。该论文强调了建模模拟动态过程以及将环境数据与对农作物的影响更紧密地结合起来的优势。CERES玉米作物模型和DSSAT软件包被选定用于这项工作，米纳斯吉拉斯州的Triângulo Mineiro地区被选定为研究区域。结果表明，Triângulo Mineiro的砖红壤潜在产量存在差异，在巴西中西部相同cerrado生态系统的其他地区外推或转让技术时应考虑到这一点。必须增加气象数据收集点的数量，因为正如弗鲁塔尔的情况所表明的那样，Triângulo的气候可以决定潜在农业生产的差异以及生产风险。该研究表明，使用作物模型可以改善土地适宜性评估，用于土地使用规划或制定农村筹资战略。
Abstract. The paper highlights the advantages of modelling to simulate dynamic processes and to couple environmental data more closely with effects on crops. The CERES‐Maize crop model and the DSSAT software package were selected for the work and the region of the Triângulo Mineiro in the state of Minas Gerais was selected as the study area. The results showed that there are differences in the potential production of the Latosols of the Triângulo Mineiro and this should be taken into account when extrapolating or transferring technology for other regions within the same cerrado ecosystem of central‐west Brazil. It is essential to improve the number of points with weather data collection since, as demonstrated for Frutal, the climate of the Triângulo can determine differences in potential agricultural production as well as risk for production. The study showed that the use of crop models can improve land suitability evaluations, for land use planning, or establishing strategies for rural funding.
