| 摘 要： | 以阳宗海为研究对象,利用landsat-8 OLI遥感影像与叶绿素a浓度实测数据,基于波段敏感性分析,构建叶绿素a浓度估测回归模型。研究表明,以波段组合(B5-B4)/(B5+B4)为参数的多项式回归模型结果最优,拟合度达0.720 1。反演得到阳宗海2018年3月1日叶绿素a浓度和富营养化指数的空间分布图,结果显示阳宗海水体整体为中营养状态。

| Abstract: | Taking Yangzonghai Lake as the research object,using landsat-8 OLI remote sensing image and chlorophyll a concentration measured data,based on band sensitivity analysis,a chlorophyll a concentration estimation regression model was constructed. The results show that the polynomial regression model with the band combination (B5-B4))/((B5+B4) as the parameter has the best result with a fit of 0.7201. The inversion obtained the spatial distribution map of chlorophyll a concentration and eutrophication index of Yangzonghai Lake on March 1,2018. The results showed that the Yangzonghai Lake was in a medium nutrient state. |
