【摘要】 对大岭山林场尾叶桉、马占相思、黑木相思、厚荚相思、卷荚相思、杉木和马尾松林分的枯落物和土壤持水功能进行研究。结果表明,林地枯落物持水量的大小顺序为:马占相思林>杉木林>厚荚相思林>黑木相思林>尾叶桉林>马尾松林>卷荚相思林;土壤持水量大小则为:杉木林>厚荚相思林>卷荚相思林>马尾松林>尾叶桉林>马占相思林>黑木相思林。对于尾叶桉林来说,随着林分年龄的增加,其枯落物持水能力增加,但持水量降低。更多还原

【Abstract】 A study on the water-holding ability of litter and soil in different plantations of Eucalyptus urophylla, Acacia mangium, A. melanoxylon, A. crassicarpa, A. plectocarpa, Cunninghamia lanceolata, Pinas massoniana was carried on at Dalingshan Forestry Station, Guangdong, China. The results showed that the order of the water-holding ability of litter is A. mangium>C. lanceolata>A. crassicarpa>A. melanoxylon>E. urophylla>P. massoniana>A. plectocarpa, and the order of the water-holding ability of soil is C. lanceolata>A. crassicarpa>A. plectocarpa>P. massoniana>E. urophylla>A. mangium>A. melanoxylon. The water-holding ability of litter in E. urophylla planted in 1990 was higher than that of being planted in 1995 but for the ability of soil, it is lower.更多还原
