中文摘要	该文测定了棉花盛蕾期至吐絮后期各时期冠层的高光谱反射率以及产量,并对棉花产量与冠层光谱植被指数进行相关分析。结果表明:棉花各生育期可见光波段、近红外波段及短波红外波段光谱反射率与产量间分别呈显著负相关、显著正相关与显著负相关。根据棉花冠层光谱波形特征,利用植被红边波段560nm反射峰、670nm吸收谷、近红外波段890nm反射峰、980和1210nm两个弱水汽吸收谷、短波红外1650和2200nm反射峰,设计归一化差值光谱指数,并与棉花产量进行相关分析,上述波段组合定义的归一化差值光谱指数与产量在各生育期均达显著或极显著相关。VARI700抗大气植被指数在各生育期均达极显著相关。
英文摘要	The aim of this study was to reveal the correlation between cotton yield and the canopy spectral index,and to build yield estimation models based on hyperspectral imaging,so as to promote the application of the hyperspectral technique in monitoring cotton growth and estimating yield.Combined with growth and development characteristics of cotton,the spectral reflectivity of the cotton canopy at different growth stages was calculated.The hyperspectral vegetation index was defined according to spectral curve characteristics.The spectral reflectivity and yield were analyzed based on estimation of the ground spectrum and yield from the budding peak stage （BPS） to later boll opening stage （BOS）.Statistical analysis showed that cotton yield was negatively correlated with spectral reflectivity in the visible light bands,positively correlated in the near-infrared （NIR） wavebands,and negatively correlated in the short-wave infrared bands during all growth stages.The normalized differences of the spectral index were determined with the following bands [560 nm,670 nm],[670 nm,890 nm],[890 nm,980 nm],[920 nm,980 nm],[857 nm,1 210 nm],[820 nm,1 650 nm] and [820 nm,2 200 nm] according to cotton canopy hyper-spectrum,which were significantly or especially significantly correlated with yield at all growth stages.At the same time,the VARI700 ARVI spectral index was especially significantly correlated with cotton yield.Remote sensing models of cotton yield at different growth stages can provide a basis for monitoring cotton growth and forecasting production.
