辣椒茶黄螨危害的冠层光谱特性与危害级别反演

为了辣椒茶黄螨大面积的遥感监测提供理论依据,测定了辣椒茶黄螨危害期间的冠层高光谱数据,并对冠层反射光谱与茶黄螨危害级别进行了相关分析。结果表明：近红外波段758、1569 nm及可见光波段537 nm为茶黄螨螨害的3个敏感波段;并基于敏感波段及由其组成的比值植被指数（RVI）和归一化植被指数（NDVI）,建立了检测茶黄螨危害级别的5种单变量线性函数模型;3个敏感波段构建的模型方程在P=0.01条件下极显著相关,且758 nm处的光谱反射率建立的模型为最优,预测相关系数达0.965。...

In order to provide a theoretical reference for large-scale remote sensing monitoring of P.latus on hot pepper,the canopy spectrum during the hazing period was measured,and the correlation between canopy reflectance spectrum and hazard rating was analyzed as well.The results showed that P.latus had three sensitive wave bands including near-infrared bands of 758 and 1 569 nm and visible wave band 537 nm.Meanwhile,five univariate linear function models for determining hazard rating of P.latus were established based on sensitive wave bands,RVI and NDVI.The model equation based on the three sensitive wave bands had very significant correlation with hazard rating.The model according to the spectral reflectivity at 758 nm was optimum with the predicted correlation coefficient of 0.965.
