| 摘 要： | 对缙云山自然保护区的常绿阔叶林、针阔混交林、竹林、灌木林林地及农地(对照)土壤的物理性质、土壤水分的入渗性能进行了测定分析,结果表明:其林地(农地)表层土壤容重的顺序为,常绿阔叶林>针阔混交林>竹林>农地>灌木林;土壤非毛管孔隙度的顺序为,灌木林>针阔混交林>竹林>常绿阔叶林>农地。灌木林林地土壤的有效水分涵蓄量要明显大于其他的森林类型,其蓄水量是竹林的1.4倍,是农地的2.14倍。4种森林类型林地及农地土壤的水分下渗性能,其层间稳渗率以腐殖质层>淀积层>母岩层;在土壤层,以竹林和农地的水分初渗为高。灌木林林地土壤的水分渗透性能极强,其初渗值达到了10.169 mm/min。从土壤水分的入渗性能来看,灌木林涵养水源和理水调洪的功能要远大于其他森林类型,针阔混交林要优于常绿阔叶林,而竹林最差。然而,对于遭遇短历时较高强度的降雨而言,竹林的理水调洪作用可能略好于针阔叶混交林和常绿阔叶林。

| Abstract: | Taking the farmland land as the control,the physical properties and water infiltration of soil under four types of forest communities namely evergreen broadleaved forest,mixed coniferous and broad-leaf forest,Phyllostachys pubescens forest and shrub forest in Jinyun Mountain Nature Reserve were measured and analyzed.The study results implied that the soil bulk densities were ranked in the order of evergreen broadleaved forest> mixed coniferous and broad-leaf forest> P.pubescens forest>farmland land>shrub forest,that of non-capillary porosity were shrub forest> mixed coniferous and broad-leaf forest> P.pubescens forest> evergreen broadleaved forest> farmland land.The water conservation of shrub forest was significantly higher than other land types,its water retention capacity was 1.4 and 2.14 times of bamboo forest and agricultural land respectively.The stable infiltration rate of the soil of five land types were ranked as humus layer>precipitation layer>rock layer,the early infiltration of P.pubescens forest and farmland soil was much higher.The shrub forest with the early infiltration rate of 10.169 mm/min showed the strong permeability.In general,the hydrological function of shrub forest was significantly better than other forest types.The hydrological function of mixed coniferous and broad-leaf forest was better than evergreen broadleaved forest,and that of P.pubescens forest was the worst among the studied forest types.However,for the high intensity rainfall of short-duration,the performance of P.pubescens forest was slightly better than mixed coniferous and broad-leaf forest and evergreen broadleaved forest. |
