以贵州清镇市流长国家现代烟草农业基地单元为研究区,针对贵州喀斯特山区烟草种植特性,首先利用SAR遥感技术,对烟草叶片进行反演并计算叶面积指数,其次对烟草生长适宜性进行评价。结合烟草的叶面积指数、适宜性等参数建立适用于喀斯特山区的烟草估产模型。经建立模型计算得出研究区每666.7 m2产量为76.17 kg,与研究区实际产量对比精度在92%以上,满足喀斯特山区大面积快速估产需要,为喀斯特山区烟草估产提供技术支撑。

Taking national modern tobacco agriculture base of Qingzhen city in Guizhou province as the research area, in al-lusion to tobacco planting features of karst mountain area of Guizhou, inversion with SAR remote sensing technology was car-ried out on the tobacco leaves and leaf area index was calculated. Tobacco yield estimation model applicable to karst moun-tainous area was eatablished by combining leaf area index with suitability parameters. The research area output per 667 m2 calculated by the model was 76.16 kg, with the output accuracy of more than 92%, which could quickly meet the karst mountain yield estimation requires in a large area, and provide technical support for estimating the karst mountain tobacco yield estimation.
