| 摘 要： | 湖泊的水体污染往往伴随着富营养化现象,水体中叶绿素a、透明度、全磷、全氮、化学需氧量及五日生化需氧量等水质参数的相关性很强.前人的研究成果表明,由于存在事实上的强相关性,可以直接建立全磷、全氮的遥感反演模型.基于这样的技术思想,洪泽湖水体内的五日生化需氧量与全磷、全氮有较强的相关性,本研究应用TM遥感影像数据直接建立了五日生化需氧量的半经验估算模型.该模型简便易用,是建立水质参数反演模型的成功尝试.

| Abstract: | Water pollution in the lake always occurs along with eutrophication.Strong correlation has been found between such water quality parameters as chlorophyll-a,SD,TP,TN,COD and BOD5 in the water body.TP and TN directly control the growth and propagation of phytoplankton,and theoretically speaking,TP and TN affect chlorophyll-a and SD indirectly,whereas chlorophyll-a and SD are primary parameters that can influence spectral reflectance characteristics.Previous research results indicate that retrieval models of ... |
