[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
