| 摘 要： | 对广东省东莞大屏障森林公园7种林分凋落物储量和持水过程进行研究，结果表明：凋落物的吸水速率随浸泡时间呈幂函数曲线降低，持水量随浸泡时间的增加呈对数曲线增长，不同森林类型的凋落物厚度为2．2～8．1cm，现存量4．42～9．31t·hm^-2，最大持水量介于4．52～14．23t·hm^-2，7种林分凋落物现存量和最大持水量的顺序为荷木〉杉木〉马占相思〉藜蒴〉鸭脚木〉粉丹竹〉马尾松，其中荷木林最大，水文生态效益显著，而马尾松林则最低。 |

| Abstract: | By the methods of field survey and soaking extraction, the storage, water-holding capacity, water-holding rate, and water-absorption rate of the litters in 7 difference plantations in Dapingzhang Forest Farm, Dongguan were studied. The results showed that the litter storage was 4.42-9.31t hm-2 and its depth was 2.2-81.cm. The water holding capacity and water holding rate of the litters increased logarithmically with soaking time while the water absorption rate assumed a power decreased function. Overall ,the litter storage and max. water-holding capacity decreased in the order of Schima superba> Cunninghamia lanceolata> Acacia mangium>Castanopsis sfissa. >Schefflera octophylla>Bambus achungii>Pinus massoniana. that the Schima superba is most greatest, and the Pinus massoniana is smallest. |
