Research on water conservation function of typical forests in Jinyun Mountain.

[Objective] This study aimed to explore the relationship between different forest types and water conservation function.[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 forest,evergreen broad-leaved forest,bamboo forest and shrub forest.[Result] The results show 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 forest(14.70%) bamboo forest(12.64%).[Conclusion] The study had great significance to rational manage forest resources,improve water environment and realize scientific management and use of water resources.
