Abstract In order to understand the water conservation function of forest in the Three Gorges Region of Yangtze River and provide fundamental basis for vegetation construction of this region,the function of canopy interception of three main forest types based on the data from fixed sample plots in Jinyun Mountain in Chongqing City were studied.The results showed that the descending order of canopy interception capability of different vegetation types was broadleaf-conifer mixed forest(18.87%),evergreen broad-leaf forest(11.76%),and Phyllostachys pubescens forest(10.68%). The descending order of throughfall coefficient of these four forest stands was: Phyllostachys pubescens forest,evergreen broad-leaf forest,and the broadleaf-conifer mixed forest.Based on analyzing and comparing the results,the effect of forest canopy interception of mixed forests is the most fine.
