| 摘 要： | 选取重庆缙云山的常绿阔叶林、毛竹林和针阔混交林为研究对象,于2012年5~10月对大气降水、穿透雨和树干径流等降水过程及其氮素输入进行研究.结果表明:①研究期间总降雨量564.88 mm,常绿阔叶林、毛竹林和针阔混交林的穿透雨量占总降雨量的比例分别为74.0%、85.0%和71.6%,且树干径流量所占比例分别为1.9%、10.3%和1.6%;3种林分的穿透雨量、树干径流量与林外降雨量之间均呈显著的线性关系(P<0.05),且穿透雨率、树干径流率与林外降雨量之间都呈对数关系(P<0.05).②与大气降水相比,穿透雨和树干径流的NO-3和NH+4浓度要高,且3种林分的大小关系为针阔混交林>常绿阔叶林>毛竹林;穿透雨和树干径流的总无机氮输入量(以N计)分别为针阔混交林(18.93 kg·hm-2)、常绿阔叶林(14.93 kg·hm-2)和毛竹林(15.31 kg·hm-2).③3种林分的无机氮输入量与穿透雨量、树干径流量之间均呈显著的线性关系(P<0.05).
