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。
In this paper, three types of evergreen broad-leaved forest, Cunninghamia lanceolata and Phyllostachys pubescens in Dagangshan area of Jiangxi Province were selected as the research objects. The main hydrological and ecological effects were analyzed before ( 2006) and post-disaster (2010) changes. The results showed that the precipitation in the evergreen broad-leaved forest, Chinese fir forest and Phyllostachys edulis forest increased due to the freezing rain and snow disaster. Compared with the trunk runoff of each forest before the snow-ice disaster, the penetration rate of rain forest The rate of change of trunk flow rate, penetration rate and canopy interception rate of broad-leaved forest was the largest, and the change range of moso bamboo forest was the smallest. The thickening and accumulation of aboveground litter increased , The water holding capacity and interception capacity of litter also increased correspondingly. After freezing rain and snow disaster, the changes of the physical properties and the main hydrological effects of the main forest soil moisture were minor, which may be related to the fact that the soil was not directly affected by rain and snow Frozen disaster damage related.
