基于无人机多光谱影像的滏阳河水质遥感反演
Remote Sensing Inversion of Water Quality of Fuyang River Based on UAV Multi-spectral Images
【摘要】 滏阳河是邯郸市的重要河流,在工业用水、农业灌溉、生态用水等方面发挥着重要作用。近年来,由于废水、污水等违规排放,滏阳河水体的污染状况明显加重。为深入系统地了解滏阳河水体污染情况,分析污染规律,本文采用水质采样和无人机航飞监测方式,对滏阳河重点区域进行了水体污染数据调查,对水质样本进行了实验室检测,并与无人机航拍获取的44种光谱参数进行相关性分析,建立了浊度(TUB)、悬浮物浓度(TSS)、化学需氧量(COD)、总磷(TP)、总氮(TN)、氨氮(NH3-N)6种水质参数的多元回归模型。研究结果表明:滏阳河在邯郸市主城区域内呈由南到北、由两岸到中心河流水质参数浓度逐渐增高的分布特征。
【Abstract】 Fuyang River is an important river in Handan city. It plays an important role in industrial water, agricultural irrigation and ecological water demand. With the development of economy and the expansion of urbanization, Fuyang River has become more and more polluted. In order to systematically understand the water pollution of the Fuyang River and analyze the pollution laws, this paper uses water quality sampling and drone flight monitoring methods to investigate the water pollution data in key areas of the Fuyang River and conduct laboratory tests on water quality samples. Correlation analysis with 44 spectral parameters obtained by drone aerial photography was carried out to establish multiple regression models of six water quality parameters, namely turbidity(TUB), suspended matter concentration(TSS), chemical oxygen demand(COD), total phosphorus(TP), total nitrogen(TN) and ammonia nitrogen(NH3-N). The research results show that the Fuyang River in the main urban area of Handan City has a gradually increasing distribution of water quality parameters from south to north, from both banks to the center.
