Abstract: This paper adopts field investigation and mathematical simulation methods,chooses 7 stand structure factors (the species composition,age,canopy density,origin,level of forest,biomass,soil thickness) to establish the coupling relationship model between the structure and function of water conservation forest in mountainous area of Beijing.Using the model to compare 8 types of Water Conservation Forest in the upper reaches of Beijing Miyun Reservoir,the results show that 1) soil and water conservation function:Broad-leaved mixed forest>Birch forest>Mongolian oak forest>Populus forest>Pine forest>Locust forest>Orientalis forest>Larch forest.2) water conservation function:Populus forest>Mongolian oak forest>Birch forest>Broad-leaved mixed>Larch forest>Orientalis forest>Pine forest>Locust forest.3) improving water quality function:Birch forest>Mongolian oak forest>Populus forest>Broad-leaved mixed forest>Orientalis forest>Locust forest>Pine forest>Larch forest.

Key words: water conservation forest, structure, function, coupling model
