摘要:
 以毛竹叶片为研究对象,利用ISI921VF-256野外光谱辐射仪获取毛竹叶片光谱反射率,分析毛竹叶片N、P、K含量和高光谱反射率的相关性,筛选N、P、K的光谱敏感波段与光谱敏感波长。结果表明,毛竹叶片N、P和K的敏感波段分别为700~850、600~750 nm和450~560 nm波段。毛竹叶片N含量在二阶导数光谱的光谱敏感波长为832 nm;P含量在一阶导数光谱的光谱敏感波长为631 nm;K含量在二阶导数光谱的光谱敏感波长为498 nm。通过毛竹叶片的N、P、K含量与光谱敏感特性的相关性分析,对毛竹叶片重要营养元素的最佳光谱敏感波段研究以及高光谱预测反演具有重要意义。
Abstract:
 Analyzing the correlation between the content of nitrogen,phosphorus and potassium in Phyllostachys pubescens and the spectral sensitive characters not only plays a significant role in studying the optimum spectral sensitive band of important nutrient elements in P.pubescens leaves,but also facilitates us to research the inversion of hyperspectral predictions.In this paper,we took P.pubescens leaves as study objects,impacts of nitrogen,phosphorus and potassium content on hyperspectral reflectance were examined to select spectral sensitive bands and wavelengths of the three elements.The results showed that the sensitive bands of nitrogen,phosphorus and potassium containing in P.pubescens leaves were located at 700-850,600-750 and 450-560 nm,respectively.The sensitive spectral wavelength of nitrogen content in the leaves was the second derivative spectra 832 nm.The sensitive spectral wavelength of phosphorus content was the first derivative spectra 631 nm.The sensitive spectral wavelength of phosphorus content in the leaves is the second derivative spectra 498 nm.
