The application of ANN realized by MATLAB to Chaohu Lake water quality assessment

SUN Li-ning~(1,2),ZHANG Zhi-yuan~(1,2),LUO Ding-gui~(3) (1.Department of Environmental and Resources,Hefei University of Technology,Hefei 230009,China; 2.Anhui Environmental Protection Bureau,Hefei 230061,China; 3.College of Environmental Sciences,Peking University,Beijing 100871,China )  
The realizing function of RBF network is provided in the toolbox of MATLAB6.5 and the method of calculating this function possesses properties such as adaptation for determining the construction network and independence of initial weight value on person. A favorable outcome appeared after we apply this function to evaluating the water quality of Chaohu Lake, attempting to use the RAND function in MATLAB to construct enough training samples, checking samples and outputs of their targets through interpolation between grades of the water quality evaluation standard, use the PRESTD function to pretreat the original data,determine the limits of water quality grades. The methods in this paper is meaningful in improving the precision and objectivity of surface water quality evaluation.
