Abstract: This article studied the hydrological,ecological effects of of the forest ecosystem through three layers of forest canopy,litter and soil. The water conservation function of 3 main types of mixed forest of Larix and Betula,Populus and Betula,Pinus and Mongolica in Mountainous area of north Hebei Province was evaluated by the method of Analytical Hierarchy Process (AHP)combined with the software MATLAB. The forest types were listed as follows:the mixed forest of Larix and Betula (0.348 4)>the mixed forest of Pinus and Mongolica(0.334 1)>the mixed forest of Populus and Betula (0.317 5). It is proved that AHP is an effective quantitative analysis method for evaluating forest function in water conservation.

Key words: AHP, mountainous area in north Hebei Province, forest vegetation, water conservation
