摘要：连续数年对 1 995年春在福建南靖的杉木采伐迹地上营造的株行距分别为 3m× 4m、4m×5m和 5m× 6m的 3种麻竹林进行水文生态功能研究。研究结果表明 :1林冠截留量与降水量和林分密度呈正相关。竹秆流和林冠穿透水与降水量呈正相关 ,与林分密度呈负相关 ;2麻竹比毛竹和其它树种更易产生秆流 ,其产生秆流所需的最小降水量为 2 .1 mm·次 -1 。株行距为 3m× 4m的麻竹林年林冠截留量、截留率、穿透水量、穿透水率、竹秆流量和茎流系数分别为 1 2 8.1 mm、1 4 .51 %、689.1 mm、8.0 2 %、66.0 mm和 7.47%。
Three kinds of Dendrocalamus latiflorus Munro experimental stands with different planting space, such as 3m×4m, 4m×5m, and 5m×6m, have been established on cutover of Chinese Fir, in Nanjing County, Fujian Province, where the ecohydrological functions of D.latiflorus stands ecosystem have been monitored continuously for several years. The results have showed that:①The canopy rainfall interception of D.latiflorus has a positive relationship with both precipitation and stands density; both the throughfall and stem flow has a positive relationship with precipitation, and a negative relationship with stands density.② D.latiflorus stands are easier to produce stem flow than Moso stands and other kinds of forests, and its minimum precipitation for producing stem flow is 2.1mm·time -1 . The canopy rainfall interception and its interception rate, throughfall and its rate, stem flow and its coefficient are 128.1mm, 14.51%, 689.1mm, 8.02%, 66.0mm and 7.47% respectively in D.latiflorus stands with 3m×4m planting space.
