| 摘 要： | 以大青山区30 a生油松人工林为研究对象,系统观测了林分对降雨的再分配作用,根据2006年的观测结果显示,油松人工林林冠穿透雨量、林冠截留、树干茎流所占降雨的比例分别为65.83%、33.04%、1.13%,枯枝落叶层有效拦蓄量为0.62mm,截留率为8.9%,地表径流率为2.6%;林冠穿透雨量、树干茎流量与林外降雨量均呈显著的线性正相关,而林冠截留量与降雨量呈幂函数关系。

| Abstract: | The distributions of rainfalls in 30a of Pinus tabulaeformis plantation in Daqing-Mountains during the growing seasons were studied in 2006.The results showed that distribution of the throughfall,canopy interception and stemflow were 65.83%,33.04% and 1.13%.The effective interception amount of litter was 0.62mm,the interception rate was 8.9%,and surface run-off rate was 2.6%.The relationship between throughfall,stemflow and rainfall were separately in linear positive correlation.The canopy interception and ... |
