Most indexes of water-saving are lack of observed data since water-saving society building as a newly complex work in China. The indexes have both the characteristics of short-term trend and stochastic variety. So it is an important work to predict them reasonably and timely. Considering all the characteristics uniformly the system cloud grey model and Markov theory are combined to form SCGM(1,1)-Markov model, and the parameters are optimized at the same time. The application results show the optimal model has higher precision on simulation than commonly used methods by 24 indexes, and the model has robust prediction ability for those indexes. The most possible value ranges of the 24 indexes are predicted by the model for 2010 also. It provides the reference to decision-making on water use planning for the management organization in the study area.
