dc.description.abstract[中文文摘]对武夷山甜槠林成熟林水文学效应的研究结果表明:观测期间,年大气降水量2678.78mm,林内雨量2182.04mm,林冠截留量为496.74mm;林内雨中,穿透雨量2082.08mm,树干茎流99.96mm;到达甜槠林地作用面的林内雨量中,被地表枯枝落叶层截留的雨量为159.84mm,地表径流量11.6mm,地下渗流量109.32mm,其余林内雨量形成土壤含水量增量并由地表物理蒸发、根系吸收以及植物蒸腾所消耗;甜槠林地o~200cm土层水分初渗率78.6mm·min-1,稳渗率15.5mm·min-1,达到稳渗历时45min,地表枯枝落叶最大持水量5.2mm,土壤蓄水量154.0mm。与国内其它地区不同类型的森林相比较,武夷山甜槠林具有较强的水文学效能。[英文文摘]Hydrological observations were made in a 76 year old Castanopsis eyrei forest of the Wuyi Mountains.The results are as follows:(1)In the study period during 1993~1994,annual gross precipitation,net precipitation (throughfall was 208204mm and stemflow was 9996mm)and interception loss were 267878mm,218204mm and 49674mm respectively.Interception rate was 1845%.(2)Net precipitation,the part of gross precipitation appearing on the forest floor,was redistributed through different routes.The part absorbed by litter layer was an annual amount of 15984mm,and accounting for 733%.The parts as surface runoff and below ground drainage were annual amounts of 116mm and 10932mm respectively,and accounting for0.53% and 5.01%,respectively.The rest was kept in soil and then lost to the atmosphere by means of ground physical evaporation or plant transpiration as absorbed by the roots.Its amount was 190128mm,and accounting for 87.13%.(3) The initial infiltration rate and stable infiltration rate for the soil layer of 0~20cm were 786mm·min-1 and 155mm·min-1 respectively.The time needed to arrive at the stable state was 45min.Water storage capacity of soil was 15041t·hm-2.The maximum water holding capacity of litter layer was 52mm.zh_CN
