This paper takes the multitemporal remote sensing images as the data source, by attaching importance to the analysis of the selection of the optimum fusion bands and the methods of image processing which the water information is extracted, which offer a theory base for remote sensing technology applied in the research of water environment.

A method of the best band combination selection based on spectral characteristics of surface features;

Ancient study indicates optimal bands combination,texture and vegetation indices can advance classification accuracy in a certain extent.

The main results are as following:1、Based on TM remote sensing image,using the valuation Index of optimal bands .

By the optimal combination analysis on the factors, the optimal combination of the factors were determined.

Furthermore,it mainly analyzed the available range of different seismic prospecting methods,main achievements and solutions,and discussed the best combination of seismic exploration methods for detecting crustal structure and locating the faults used in the present stage,that is,to trace.

The effectiveness of classifier combination and the problem of best combination both have to be solved.
