Abstract:
The present paper deals the application of the cluster analysis method in the basic categories of classification for salt-affected soils on the basis of the analytical data of forty profiles. The results obtained are: 1. According to the coefficients of distance matrix among the samples, the seven genera originally classified can beg reclassified into five genera at 0.08 distance level through cluster analysis.
