运用野外实地测量和室内浸提法对4种套种雷公藤人工林凋落物持水量、持水率和吸水速率进行了研究。结果表明：4种林分的凋落物最大持水量大小为杉木林(11.66 t/hm2)＞马尾松林(6.81 t/hm2)＞厚朴林(5.90 t/hm2)＞纯林(4.28 t/hm2)；在不同浸泡时间段，林分的凋落物持水率大小为厚朴林＞纯林＞马尾松林＞杉木林；凋落物最大持水率为厚朴林(205.12%)＞纯林(163.33%)＞马尾松林(139.33%)＞杉木林(120.96%)；4种不同种植模式雷公藤林分的凋落物吸水速率大小为厚朴林＞纯林＞马尾松＞杉木，浸泡0.5 h 后的吸水速率分别为2630.05、2407.32、2035.09和1592.14 g/kg/h。凋落物持水量与浸泡时间、凋落物持水率与浸泡时间呈现极显著的(P＜0.01)对数递增函数关系，凋落物吸水速率与浸泡时间呈现出极显著的(P＜0.01)递减幂数函数关系。

By the methods of using soaking extract method and field investigation, we studied the water-holding capacity, water-holding rate, and water-absorption rate of litter in four kinds of Tripterygum wilfordii of plantation. The results were as follows: The maximum water holding capacity in 4 types of forests are Chinese fir (11.66 t/hm2) > masson pine (6.81 t/hm2) > magnolia (5.90 t/hm2)> pure forest (4.28 t/hm2). Under different soaking time, litter water holding rate showed magnolia > pure forest >masson pine> fir forest. Maximum water holding rate of the litter is of magnolia 205.12% > pure forest 163.33%> masson pine139.33% > Chinese fir 120.96%. Stand water absorption rate of 4 different planting patterns is magnolia> pure forest > masson pine > Chinese fir, and water absorption rate after 0.5 hours were 2630.05, 2407.32, 2035.09 and 1592.14 g/kg/h. The relationship between water holding capacity of litter with the soaking time, water retention rate with the soaking time increased according to logarithmic equation(P<0.01), the relationship between water absorption rate and soaking time decreased according to exponential equation(P<0.01).
