【摘要】 为了解中亚亚热带常绿阔叶林地的土壤状况,以重庆缙云山4种林分为研究对象,通过标准地调查、土壤物理性质及持水能力测定和入渗实验,对林地枯落物和土壤水分效应进行研究。结果表明:1)缙云山林地土壤具有较强的持水能力,1m深土壤持水能力为9．50-13．17mm。2)枯落物蓄积量为16．21-32．42t/hm2,枯落物持水率为针阔混交林>灌木林>常绿阔叶林>楠竹林,持水量为灌木林>针阔混交林>常绿阔叶林>楠竹林。3)菲利浦模型较好地反映研究地区不同类型林地土壤入渗过程。更多还原

【Abstract】 In order to know the soil characteristics of subtropic evergreen broadleaf forest in mid-Asia, four forest stands in Jinyun mountain of Chongqing was selected as objects. Through investigating standard spots, determining soil physical characteristics and water-holding capacity, and experimenting on soil infiltration, forest litter and soil hydrological effect was studied. The results indicated that the forest soils of 1 m deep have an obviously strong water-holding capacity within a range from 9.50 to 13.17 mm. The litter storage amount is from 16.21 to 32.42 t/hm2 . The sequence of maximal water retention rate of litter is the coniferous and broad-leaves mixed forestlands > shrub lands > evergreen broad - leaves forestlands > phyllostachys pubescent forest-lands. The sequence of maximal water retention of litter is the shrub lands > coniferous and broad-leaves mixed forestlands > evergreen broad-leaves forestlands > phyllostachys pubescens forestlands. The Philip infiltration model can better reflect the soil infiltration process of different forest types in research area.更多还原
