[Method] Based on field survey and experimental analysis, water conservation function of four typical forest stands in Jinyun Mountain of Chongqing was explored, including conifer-broadleaved mixed for- est, evergreen broad-leaved forest, bamboo forest and shrub forest. [Result] The re- sults showed that the order of saturated water storage capacity of soil in four forest stands was shrub forest (266.48 mm) 〉 conifer-broadleaved mixed forest (190.40 mm) 〉 evergreen broad-leaved forest (186.80 mm) 〉 bamboo forest (174.80 mm); the order of maximum water-holding capacity of litter was shrub forest (8.06 mm) 〉 conifer-broadleaved mixed forest (4.71 mm) 〉 evergreen broad-leaved forest (4.32 mm) 〉 bamboo forest (3.34 mm); the order of canopy interception in various forest stands was conifer-broadleaved mixed forest (16.15%) 〉 evergreen broad-leaved for- est (14.70%) 〉 bamboo forest (12.64%). [Conclusion] The study had great signifi- cance to rational manage forest resources, improve water environment and realize scientific management and use of water resources.展开更多
