中文摘要：
2004年对武夷山甜槠林不同水文分量定位观测，探讨甜槠林森林水文与降水的关系。结果表明：1）2004年共发生降水219次，年降水量1767.4mm，穿透水、茎流量和林冠截留量分别为1304.9、245.0和217.5mm；穿透率、茎流率和截留率分别为73.8%、13.9%和12.3%；2）同次降水中，林内不同位置的穿透雨量差异显著，穿透水量与大气降水量之间存在明显的线性关系；3）随着胸径的增加，茎流量减小，形成茎流的时间推迟；4）当降水量〈202.1mm时，林冠截留量随着降水量的增加而增加；当降水量超过202.1mm后，林冠截留量趋于定值52.5mm。
英文摘要：
Hydrological effects of Castanopsis eyrei forest in Wuyi Mountain were studied in 2004. The results indicated： 1） There were 219 precipitations in 2004 and the total precipitation during this period was 1 767.4 mm, throughfall, stemflow and interception was 1 304.9, 245.0 and 217.5 mm, respectively, and which accounted for 73.8% , 13.9% and 12.3% of precipitation, respectively; 2 ） The throughfalls at different places in the forest were different significantly for the same precipitation, furthermore the relationship between throughfall and total precipitation was linear; 3） With the DBH increasing, the stemflow decreased, and the time taking stemflow was postponed; 4） When precipitation was lower than 202.1 mm, the interception increased with precipitation increasing, when precipitation was higher than 202.1 mm, the interception inclined to 52.5 mm.
