| 摘 要： | 烟草长势信息是烟草生产管理的重要依据,全面了解遥感技术在烟草长势监测及估产中的应用进展,为利用遥感技术支撑科学化、精细化烟田管理提供科学参考。在对相关文献分析和归纳的基础上,从地面光谱、无人机遥感、卫星遥感3种尺度对目前遥感技术在烟草长势监测与估产方面的应用进行系统总结,并对进一步研究进行展望。（1）基于地面光谱对烟草的监测,主要是利用反射率光谱及其不同的变换形式、光谱指数和光谱位置变量估测其生理生化参量（氮、磷、钾、生物量、叶面积指数、叶绿素等）,为诊断烟草生长、健康状况、成熟度提供依据,进一步实现烟草长势监测、估产与品质评定。（2）利用无人机遥感技术能够在小尺度上对作物的面积进行提取、监测长势及估产,但受搭载相机分辨率、地形、自身稳定性等影响,不能监测烟草的细微变化。（3）参考LandSat、SPOT、MODIS、HJ-1等光学遥感数据以及SAR数据,利用遥感影像融合、分类等技术能够实现对大面积烟田病害、长势进行监测和产量估计。结合多源、多平台遥感数据,对烟草的参数进行定量研究,并利用同化技术对大尺度上烟草生长过程进行动态监测,来探索烟草的最佳采收期是未来研究的重点。

| Abstract: | Tobacco growth information is an important basis for tobacco production management. Through a comprehensive understanding of the application of remote sensing technology in tobacco growth monitoring and yield estimation, the study aims to provide a scientific reference for the use of remote sensing technology in refined tobacco field management. Based on reviewing relevant literatures, the application of remote sensing technology in tobacco growth monitoring and yield estimation was systematically summarized from three scales of ground spectrum, UAV(unmanned aerial vehicle) remote sensing, and satellite remote sensing, and the prospect of further research was also discussed. (1)Based on the ground spectrum, the physiological and biochemical parameters (nitrogen, phosphorus, potassium, biomass, leaf area index, chlorophyll, etc.) of tobacco were estimated by reflectance spectrum and its different transformation forms, spectral index and spectral position variables, providing a basis for the diagnosis of tobacco growth, health status and maturity. Tobacco growth monitoring, yield estimation and quality evaluation could be realized. (2) UAV remote sensing technology could be used to extract tobacco areas on a small scale, monitor and estimate yield, but it could not monitor the subtle changes of tobacco due to the influence of the resolution, terrain and self stability of the camera. (3) With optical remote sensing data such as LandSat, SPOT, MODIS HJ-1, etc., as well as SAR data, by remote sensing image fusion, classification and other technologies, large-area tobacco field disease, growth monitoring and yield estimation could be achieved. The future research will focus on quantitatively studying the tobacco parameters by combining with multi-source and multi-platform remote sensing data, and conducting the dynamic monitoring of tobacco growth process on large scale by assimilation technology, thus to explore the optimal harvest time of tobacco. |
