摘　　要：对储粮生态系统特点、粮仓温度对象特点做了详细的叙述。指出了粮库生态系统是外界自然环境因素和内在因素的共同作用,从粮仓仓型、温湿迁移、外部环境因素、粮仓所处地理位置等方面阐述影响粮仓温度场演变的结果。介绍当前国内外研究者建立粮仓温度数学模型的原理及依据,对主要数学模型及相应研究方法例如CFD、有限元法及应用做了系统的阐述。指出了目前研究方法上的不足及存在的问题,为后续粮仓温度研究提供了参考和方向。Storage temperature is the key index on monitoring the grain information and storage safety. The present study was to descript detailed on the granary ecosystem characteristics and grain storage temperature features. It pointed out that the granary ecosystem was the coefficient of the natural environmental and internal factors,which was to effect the barn temperature field evolution from the barn type,temperature and moisture migration,external environmental factors,granary location and other aspects. The article introduced the principle and basis granary temperature mathematical models established by the current researchers,and systematically stated the main mathematical models and corresponding research methods,such as CFD and finite element method and its application. The paper also compared the characteristics of all kinds of research methods in the application and summarized the defects of the current research methods and existing problems,which provided the reference and direction for subsequent research in the intelligent algorithm application in the grain temperature.
