基于辐射传输模型的巢湖叶绿素a浓度反演
|
摘要
应用局限性小、普适性强的叶绿素a浓度反演算法是提高定量遥感技术实用性的关键。基于辐射传输机理,分析内陆湖中叶绿素a等因子的光学特性,建立像元反射率与因子浓度的物理模型。应用模型同时反演巢湖不同时相的叶绿素a浓度,决定系数R2可达0. 877 8,证明了模型时相局限性小、普适性强。进而选取预处理后的2016年巢湖不同时相Landsat8影像,反演并分析巢湖叶绿素a浓度的时空分布特征。研究表明,该模型不受时相限制、普适性强,可推动定量遥感技术在水质污染研究方面的应用。
The algorithm of chlorophyll-a concentration inversion with higher universality is the key to improving the practicability of quantitative remote sensing technology. Based on the radioactive transfer mechanism,the optical characteristics of chlorophyll-a and other factors in inland lakes are analyzed,and a physical model of pixel reflectivity and factor concentration is established. The model was applied to the remote sensing data of different phases in Chaohu. The determination coefficient was 0. 877 8 and the average relative error was only11. 61%. This proved that the precision of the model was higher and the universality was stronger. Then,the preprocessed Chaohu remote sensing image was applied to the model,and the spatial and temporal distribution characteristics of eutrophic pollution in Chaohu were obtained,which is consistent with the regulation of the seasonal multiplication of algae. The model used in this study has high accuracy and universality and thus can promote the application of quantitative remote sensing technology in water pollution research.
