摘要:
冠层温度是甘蔗长势监测的一个重要参数，准确估算甘蔗冠层温度对甘蔗旱情监测、精准估算甘蔗产量，评估甘蔗品质均具有重要意义。但生产实际中仍是以定点或手工方式观测作物冠层温度，费时费力且无法满足精准糖业的时效性要求。热红外遥感技术可快速、无损获取大面积地表温度，但当像元包含多种地物时，需要反演组分温度，以满足实际应用需求。文章以Landsat-8遥感影像为基础数据源，采用双源能量平衡模型（TSEB）、植被指数及地面定点观测数据，反演甘蔗冠层温度。试验分析表明，反演甘蔗冠层温度与实测温度具有较好的时空一致性，表明通过地表温度分解的方法获得的甘蔗冠层温度具有可行性。文章方法可以为甘蔗干旱监测及甘蔗育种提供数据支持。
Abstract:
Canopy temperature is an important parameter for sugarcane growth monitoring. Accurate estimation of sugarcane canopy temperature is of great significance for sugarcane drought monitoring, accurate estimation of sugarcane yield and evaluation of sugarcane quality. However, in practice, crop canopy temperature is still observed by fixed-point or manual methods, which is time-consuming and laborious and can not meet the timeliness requirements of precision sugar industry. Thermal infrared remote sensing technology can quickly and non destructively obtain the surface temperature of a large area, but when the pixel contains a variety of ground objects, it is necessary to retrieve the component temperature to meet the practical application needs. Based on Landsat-8 remote sensing image as the basic data source, the sugarcane canopy temperature was retrieved by using double source energy balance model (TSEB), vegetation index and ground fixed-point observation data. The experimental analysis shows that the inversion of sugarcane canopy temperature has good temporal and spatial consistency with the measured temperature, which indicates that the sugarcane canopy temperature obtained by the decomposition of land surface temperature is feasible. This method can provide data support for sugarcane drought monitoring and sugarcane breeding.
