摘　　要：基于大田环境下红外测温仪长期连续自动监测的水稻冠层温度,研究了水稻关键生育期冠层温度与光照、气温、空气相对湿度、风、天气现象等现有地面气象观测要素之间的相关关系,并建立了在晴朗天气模式下以气温、大气湿度、作物蒸腾速率、总辐射辐照度为因子的水稻冠层温度模拟模型,回归模型和各回归系数经统计检验达1%极显著水平。旨在为通过气象监测预测水稻高温热害发生的机率、客观评价热害程度、制定生态或农艺避(抗)热措施提供理论依据。The relationship between canopy temperature of rice and meteorological factors was studied based on field obser-vation data of the rice canopy temperature by precision infrared temperature sensor.A rice canopy temperature simulation model under sunny weather with air temperature,air humidity,crop transpiration rate and total radiation intensity as independent variables was developed,which passed the significance examination（P0.01）.The study aimed at providing support for observation and prediction of extreme heat injuries to rice and corresponding countermeasures.
