Abstract In this paper, to evaluate the water conservation capacity on the litter layer and soil layer of three main forest types in southern slope of Xiaoxing’anling Mountains, the eleven indices affecting water conservation capacity were selected, and analytic hierarchy process (AHP) method was employed. The results showed that natural poplar and birch mixed forest performed the best water conservation capacity (0.4271), followed by larch plantation (0.3687), and natural Korean pine forest was the weakest (0.2042). The results were agreed with the reality. The AHP method can be used to give quantitative evaluation on water conservation capacity in different forest types.
