重庆缙云山典型林分水源涵养功能研究(英文)

[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(266.48mm)>针阔混交林(190.40mm)>常绿阔叶林(186.80mm)>楠竹林(174.80mm);枯落物最大持水量顺序为灌木林(8.06mm)>针阔混交林(4.71mm)>常绿阔叶林(4.32mm)>楠竹林(3.34mm);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。

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 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 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.
