摘要:
遥感技术由于具有快速、宏观、低成本和周期性的优点,便于探测水质的时空变化,已成为水质参数检测的重要手段。目前能够直接进行遥感反演的水质参数主要是悬浮物浓度、叶绿素浓度、可溶解性有机物等光学活性物质,并已经建立了许多反演模型。但是这些模型直接用于水质的遥感监测仍存在一些问题。今后,利用3S技术将地面观测和遥感观测结合起来,可望推动水色要干的实际应用。

Rrtrieval and Monitoring of Water Quality Parameters based on Remote Sensing Data
Abstract:
Remote sensing technology has become an important way of monitoring water quality parameters because of its advantages such as fast,regional,global,low-cost and periodic.Now,the water quality parameters retrieved by remote sensing are mainly optically active substances in water such as the concentration of suspended solids,chlorophyll-a and colored dissolved organic matter.Although many retrieval models of water quality parameters based on remote sensing data have been established,they still have some problems when be used in remote sensing monitoring of water quality directly.Combination of ground observation and remote sensing ovservations by 3S technology will be a useful way to promote the practical application of water color remote sensing.
