| 摘 要： | 观测了河岸缓冲带硬头黄竹人工林群落2008年1个观测年的大气降雨量、穿透雨量和树干茎流量,并对其取样进行氮、磷养分分析。结果表明：全年降雨量为973.3 mm,穿透雨量和树干茎流量分别为586.0、71.7 mm,占同期降雨量的60.2%、7.4%。以24组不同雨量级数据用线性方程拟合林外降雨量与穿透雨量和树干茎流量间的关系,穿透雨和树干茎流的养分浓度与降雨量呈负相关,表现出明显的季节性变化。全年向林地内输入总氮59.543 kg/hm2,其中NH4＋、NO3-和NO2-的养分含量分别为35.010、20.461、1.423 kg/hm2;输入总磷0.230 kg/hm2,其中PO43-养分含量0.123 kg/hm2,穿透雨和树干茎流带来的养分对竹林的生长和养分循环有重要的生态意义。

| Abstract: | The total precipitation,through rainfall and stem-flow of the Bambusa rigida plantation in the riparian buffer strips in the whole year of 2008 were observed,and N,P nutrient contents of the soil samples were analyzed.The results showed that the total precipitation of the whole year 2008 in the studied area was 973.3 mm,the yearly through rainfall and stem-flow were 586.0 mm and 71.7 mm respectively,which accounted for 60.2% and 7.4% of the total precipitation.The correlations among the total precipitation,... |
