摘　　要：In this study, the quadrat method was used to study the effects of tsaoko （Fructus tsaoko） plantation on tree diversity and canopy structure of two natural habitats of eastern hoolock gibbon （Hoolock leuconedys）： Nankang （characterized by extensive tsaoko plantation） and Banchang （relatively well reserved and without tsaoko plantation）. Totally, 102 tree species from 25 families and 16 woody liana species from 10 families were recorded in Nankang, whereas 108 tree species from 30 families and 17 woody liana species from 12 families were recorded in Banchang. Although the tree species between two habitats is different, both habitats are characterized by enriched food resources for eastern hoolock gibbons, sharing similar dominant plant families. Due to tsaoko plantation, tree density proportion and diversity of forest layer I （〉20 m） in Nankang were both significantly decreased, but the tree density of layerH （10-20 m） increased. Likewise, in conjunction with these behavioral observations, we also address potential impacts of tsaoko plantation on the behavior of eastern hoolock gibbon.In this study, the quadrat method was used to study the effects of tsaoko(Fructus tsaoko) plantation on tree diversity and canopy structure of two natural habitats of eastern hoolock gibbon(Hoolock leuconedys): Nankang(characterized by extensive tsaoko plantation) and Banchang(relatively well reserved and without tsaoko plantation).
