| 摘 要： | 为了利用遥感卫星影像资料对湖泊水质进行连续、大范围的监测,以鄱阳湖为研究对象,通过对水体实测高光谱的特征分析,采用分期统计回归的方法建立总悬浮物(TSS)浓度反演模型,利用MODIS影像反演鄱阳湖TSS浓度的空间分布,并分析其时空分布特征.研究结果表明:红光和近红外波段是反演水质参数TSS的敏感波段,在同一环境下分析,...

| Abstract: | In order to monitor the water quality of Poyang Lake by remote satellite image continuously and in a large-scope,through analysis on measured spectrum characteristics of water body and the staged statistic regression analysis,the regression analysis model on total suspended sediment of Poyang Lake was set up and its spatial-temporal TSS concentration distribution was analyzed by the model.The research results showed that red and near infrared bands were TSS sensitive bands,under the same environment,it can ... |
