| 摘 要： | 根据马尔柯夫过程的原理,在水质级别评价结果的基础之上,构造水质变化的概率转移矩阵,并对转移概率赋权计算绝对进步度,然后在此基础上引出相对进步度的概念,用相对进步度来评价河流水质在一段时期内的变化程度.运用该方法计算了中国四大河流2005年的水质相对进步度,并对计算结果进行了分析.

| Abstract: | The paper constructed a type of possibility transition matrix,based on the theory of Markov process and the result of water quality evaluation,and then endowed the transition possibility with a weight to calculate the degree of absolute advancement.Based on it,the concept of relative advancement was presented.It was used to evaluate how much the water quality changed in a period of time.This method was used to calculate 4 rivers' water quality degree of relative advancement in China,and the result of calculation was analyzed. |

| Keywords: | water quality evaluation possibility transition matrix Markov process degree of advancement |
