Abstract

Abstract

It is a valid route for quantitatively remote sensing on water pollution to build model according to the physical mechanisms of scattering and absorption of suspended substance, pollutant and molecules of water.Remote sensing model for water pollution based on single scatter ing is simple and easy to be used, but the precision is affected by the turbidity of water.The char acteristics of the energy composition of multiple scatter ing are analyzed, and it is proposed that, based on the model of single scattering, if the flux of the second scattering is consider ed additionally, the precision of the model will be remarkably raised, and the calculation is still very simple.The factor of the second scattering is deduced to build a double scattering model, and the practical arithmetic for the calculation of the model is put for ward.The result of applying this model on the water area around the Zhujiang River Estuary shows that the precison of the model basing on double scattering is obviously improved.The result also shows that the seriously polluted water area was distributed on the north of Lingding Sea, the Victoria Bay of Hong Kong and the Shenzhen Bay.
