南方丘陵地区路域植被光谱处理与分析

以长沙—湘潭高速公路路域植被为研究对象,进行植被实地调查和野外光谱测定,分析主要植被类型光谱曲线,健康植被与非健康植被光谱差异,对植被光谱数据进行一阶微分和微分增量处理对比研究。研究表明:光谱反射率一阶微分和微分增量处理对消除土壤背景对地物光谱影响均有效,但微分增量处理更能突出植被信息。研究对遥感植被光谱分析具有一定参考价值。

The vegetation spectral processing and analysis of the domain of road in southern hills

It presents the vegetation of road in Cbangsha, Hunan-Xiangtan Expressway as the research objectand conducts the vegetation field survey and spectral measurement. The text analyses the spectral curve of the main type of vegetation, and the spectral difference of healthy and non-healthy vegetation, comparing the result of spectral data with first derivative and differential gain. The results show that： the processing of differential and differential gain for spectral reflectance have a good effect to remove the influence of soil background on spectral, But the method of differential gain can serve to highlight the information of vegetation. The study has an important reference value for the spectral remote sensing of vegetation.
