ABSTRACT
Water quality monitoring is the main basis of water quality assessment and water pollution prevention and control. Accurate and efficient water quality monitoring for water conservation is very important. Water quality of traditional monitoring needs pointwise collection and quantitative chemical analysis. This method not only requires plentiful of labour, material and financial resources, but also inefficient. Therefore, it is more and more difficult to satisfy social development with backward techniques. Since the 1970s, the development of satelite remote sensing bring new approach to this industry [Wang et al. 2012]. Remote sensing technology, by contrast, has the following advantages which are much more excellent than traditional methods, such as wide coverage, temporal synchronization, low cost, real-time acquisition and convenient monitor for long term and dynamically [Yu et al. 2008]. With the progress of remote sensing technology theory, method research and applications, direct or indirect monitoring content have been involved Chlorophyll, suspended solids, transparency, water tempreture, dissolved organic matter and so on [Dekker 2002, Gu et al. 2007, Giardino & Pepe 2001]. These studies also demonstrated the feasibility of remote sensing inversion.
