Abstract:: Forest litter layer and soil layer water-holding capacity are two important links to monitor whether the function of forest water conservation is good or not. In order to evaluate the water conservation function for different types of forest in central Yunnan urban water sources intuitively, simply, scientifically and reasonably, and on the basis of the different types of forest litter layer water-holding capacity, the physical and chemical properties of soil layer, and the soil water-holding capacity, 17 representative evaluation indicators which impact the forest litter layer and soil layer water-holding capacity as the evaluative indices of water conservation function was collected for different types of forest in central Yunnan urban water sources. The water conservation function of different forest types in Jiulongdian, Chuxiong was evaluated by using the Euclid approach degree fuzzy matter element model. The size of the European approach degree is in the oder of R_{mixed forest} > R_{cyclobalanopsisglauca forest} > R_shrub > R_{man-made eucalyptus forest}. It concludes that comprehensive water conservation function of the mixed forest is the best, followed by the cyclobalanopsis glauca forest and the shrubs, and the planted eucalyptus forest is the worst.
