The characteristics of rainfall redistribution under the canopy of three typical Phyllostachys edulis forests (Ph. edulis and Cunninghamia lanceolata mixed forest(Ⅱ), Ph. edulis pure forest(Ⅲ) and Ph. edulis and broadleaved tree mixed stands(Ⅳ)) in the Northern of Fujian province were studied in comparison with C. lanceolata forest (Ⅰ) and evergreen broadleaved forest(Ⅴ). The results showed that: Throughfall rates ranged from 46.23 % to 86.22 %, the order of average throughfall rates was:Ⅰ(77.0 %)＞Ⅲ(75.0 %)＞Ⅳ(73.7 %)＞Ⅱ(70.3 %)＞Ⅴ(67.7 %).It was found that, as rainfall depth and intensity increased, the stemflow of three Ph edulis forests increased with a higher proportion than C. lanceolata forest and evergreen broadleaved forest. The order of stemflow rates was Ⅳ(69.2 mm)＞Ⅲ(52.0 mm＞Ⅱ(37.3 mm)＞Ⅴ(23.0 mm)＞Ⅰ(17.6 mm), and the order of least rainfall produced by stemflow in the five forest stands was:Ⅱ(6.4 mm)＜Ⅳ(6.9 mm)＜Ⅲ(7.5 mm)＜Ⅴ(8.9 mm)＜Ⅰ(10.4 mm). Throughfall, stemflow and canopy interception were linearly correlated to rainfall outside the stands at the extremely significant level(p＜0.01),that the equation Y=a+bX could be used to show the relationship between the rainfall and througfall, and three curve equation (Y=β0+β1X+β2X2+β3X3) was applied to explain the relationship between rainfall and canopy interception.The canopy interception rates ranged form 14.1 % to 53.5 %, that the order was:Ⅴ(31.3 %)＞Ⅱ(28.2 %)＞Ⅳ(23.5 %)＞Ⅲ(22.9 %)＞Ⅰ(22.3 %). In summary, Ph. edulis and Cunninghamia lanceolata mixed forest had the highest interception capability among three different types Ph. edulis forest on heavyhard rain condition while the pure Ph. edulis forest performed best with interception capability on light and moderate rain condition.
