The research results show:(1) we combine time series method with the dispersed Markov Chains theory of stochastic process, and present a Markov Model based the time series analysis for predicting the precipitation for groundwater resources evaluation. Results show that the time series-Markov Model is efficient, and it has higher accuracy than that of the single model of time series;(2) started from the systematic point of view, we analyze the metabolic process of groundwater, establish the ultimate metabolic equation of groundwater for protecting the water resources, and discuss the value of reducing evaporation for making full use of the water resources;(3) Through a theoretical analysis of the results of the experiments, we draw a conclusion: the critical depth on evaporation of groundwater is in step with the height of the maximal capillary rise of media.
