The improved Zadeh formula was used to normalize thewater quality indicators. The probability transition matrix of water quality changes was constructed, and a MATLABprogram was written to calculate the degree of progress of water quality changes of the river as well as that of fivemonitoring sections. The results show that the total degree of improvement of the water quality in the Wangyu...
