... on model and GM(1,1) Grey Forecasting Model, it studies the current water resource capacity of Guizhou Province, and predicts the future water resource capacity of the area, thus drawing a conclusion that water resource in Guizhou is of abundant total volume. As for the allocation that optimizes the abundant water resource, however, it is shown in the researches that the water resource in Guizhou Province is of rather low utilization efficiency and poor mobilization capability. On this basis, a fuzzy synthetic evaluation model is set up based on AHP so as to provide a reasonable evaluation plan of intelligently optimized allocation of water resource in Guizhou Province.
