| 摘 要： | 目的]探讨不同类型林地与涵养水源功能的关系。方法]通过实地调查与实验分析,对重庆缙云山中针阔混交林、常绿阔叶林、楠竹林和灌木林4种典型林分的水源涵养功能进行了分析。结果]4种林分的土壤饱和蓄水量顺序为灌木林(266.48 mm)>针阔混交林(190.40 mm)>常绿阔叶林(186.80 mm)>楠竹林(174.80 mm);枯落物最大持水量顺序为灌木林(8.06 mm)>针阔混交林(4.71 mm)>常绿阔叶林(4.32 mm)>楠竹林(3.34 mm);各种林分的林冠截留率顺序为针阔混交林(16.15%)>常绿阔叶林(14.70%)>楠竹林(12.64%)。结论]该研究对合理经营森林资源、改善水环境、实现水资源的科学管理和利用具有重要意义。

| Abstract: | 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. |
