Abstract: In the paper, the author introducs the calculating principle,method and programme of the Q-type system cluster analyssis which are applied to the classification of groundwater chemistry. Calculatingoverproof index is used as a method to handle normalization.In the calculating methods, the methods of onedimension storage and reducing order of matrix successively during the prccess of cluster are used to save storage and to accelerate the calculating rate.
