摘要本文分析了国内外遥感技术在水环境监测上的研究现状，总结了部分遥感监测在水环境监测中的应用方法，其中主要介绍了利用遥感影像对水环境悬浮泥沙、叶绿素a以及有机物进行监测的方法。以遥感技术对悬浮泥沙浓度监测方法为例，针对钱塘江的水环境现状，设计合适的研究方案，尝试通过水体光谱信息与遥感影像信息获取悬浮泥沙浓度信息。实验过程为利用2015年5月ASD手持光谱仪获取的实验区域水体遥感反射率信息，通过经验模型的计算，得到2015年钱塘江实验区域的悬浮泥沙估算浓度，再结合2015年5月对应实验区域的Landsat-8遥感影像，建立回归模型，对2014年3月对应实验区域的Landsat-8影像的悬浮泥沙浓度进行反演，获取2014年实验区域的悬浮泥沙浓度，以验证模型的可用性。结果表明选取Landsat-8影像对悬浮泥沙最为敏感的波段组合波段3与波段2，以其波段比值为参数建立回归模型，得到的回归模型对2014年的遥感影像的进行反演，取得的结果较为满意。88324

Abstract This paper analyzes the research status of remote sensing technology in water environment monitoring, summarizes the application of some remote sensing monitoring in water environment monitoring, and mainly introduces the method of monitoring the water environment suspended sediment, chlorophyll a and organic matter using remote sensing image。 The method of monitoring suspension and sediment concentration by remote sensing technique is taken as an example, in view of the current situation of the water environment in Qiantang River, the design of the suitable research program is designed, and the information is obtained from the information of water spectrum and remote sensing information。 The experimental process was used to obtain the information of the remote sensing reflectivity in the area of water in the experimental area obtained by the ASD handheld spectrometer in May 2015, based on the empirical model, the estimated concentration of suspension and sediment in the experimental area of Qiantang River in 2015 was obtained, the regression model was established by using the landsat-8 remote sensing image in the experimental area in May 2015, the suspension and sediment concentration of the landsat-8 image in the experimental area in March 2014 was reversed, the suspension sediment concentration of the 2014 experimental area is obtained to verify the availability of the model。 The results show that the combination band, band 3 and band 2 are the most sensitive to the floating sediment in landsat-8,the regression model was established based on the ratio of the band, and the regression model was obtained, and the results were satisfactory。
