摘要/Abstract

摘要： 以江西大岗山地区的常绿阔叶林、杉木林(Cunninghamia Lanceolata)、毛竹林(Phyllostachys pubescens)等3种林型为研究对象,对比分析了其主要水文生态效应在雨雪冰冻灾害前(2006年)与灾害后(2010年)的变化。结果表明:雨雪冰冻灾害造成常绿阔叶林、杉木林、毛竹林3种林型林内降雨量增加,相比雨雪冰冻灾害前各林型的树干径流率、穿透雨率都有所增大,截留率变小,其中阔叶林的树干径流率、穿透雨率和树冠截留率变化幅度最大,毛竹林的变化幅度最小;3种林型地上枯落物增厚和蓄积量增多,枯落物持水量和截留能力也相应增大;雨雪冰冻灾害后3种林型土壤主要水分物理性质和主要水文效应变化较小,这可能与土壤在枯落物下层未直接受到雨雪冰冻灾害破坏有关。

Abstract: The dynamic of the main hydrological effect of three forest types(evergreen broad-leaved forest,Cunninghamia Lanceolata forest and Phyllostachys pubescens forest) was studied before(2006 year) and after(2010 year) freezing rain and snow disaster in Dagang Mountains of Jiangxi Province.The result showed the rainfall rate increased after the freezing rain and snow disaster within three forest types.Comparing the pre-disaster,the through-fall rate and the stem flow rate increased while the interception rate was reduced for the forest crown of three forest types in the post-disaster.The percentage change of the stem flow rate,the through-fall rate and the rejection rate of evergreen broad-leaved forest was the biggest,and Phyllostachys pubescens forest type was the smallest among three forest types.The thickness and the stock volume of ground litter increased,and the capacity of water-holding and interception of ground litter increased correspondingly after freezing rain and snow disaster in three forest types.The water physical characteristics and the hydrological effect of soil changed little after freezing rain and snow disaster,and it might be related with the cause that freezing rain and snow disaster did not directly destroy the ground litter lay in three forest types.
