基于高光谱遥感预测鲜桃产量的现实意义及可行性分析

Feasibility of monitoring and estimating peach yield with hyper spectral remote sensing

高光谱遥感技术已经在林业、农业中得到广泛应用,但国内外未见有应用该技术在经济林果产量的监测预测研究的报道。文章分析了利用高光谱遥感技术预测鲜桃产量的必要性和意义,拓宽了遥感应用的思路,并对其可行性进行了深入探讨,认为利用果实成熟前冠层的光谱特征可以预测果实的产量指标,关键是在果树冠层光谱特征中寻找相应的光谱反射率或其衍生指数与果实产量指标之间的相关关系,并建立预测模型。

Hyper spectral remote sensing technology has been widely used in forestry and agriculture. But the application of the technology in the economic fruit production monitoring and prediction has not been reported at home and abroad. The necessity and significance of using hyper spectral remote sensing technology to prediet the yield of peach were analyzed to widen the applying way of remote sensing, and its feasibility was also discussed deeply in the paper. It thought that applying the spectral characteristics of canopy of fruit before maturing could predict the yield indexes of fruit, and the key was to study the correlation among the spectral rcflectivity or its derivative indexes and the yield indexes of fruit, then the prediction model should be set up.
