| 摘 要： | 从促进桉树人工林多种效益持续稳定高效的发挥和林地可持续利用的角度,开展桉树人工混交复层林研究,通过巨尾桉杉木和巨桉马尾松人工混交复层林的生长和生态效应的分析结果表明,巨尾桉与杉木及巨桉与马尾松混交所形成的复层林能有效提高桉树的生长量和林分总蓄积量;桉树混交复层林独特的林分结构提高了林下植被多样性,明显改善土壤结构,有利于协调土壤水、肥、气、热平衡,而且林内凋落物量多且成分复杂,显著提高了土壤肥力。

| Abstract: | The growth and ecological effects of artificial multi-storied mixed forest of Eucalyptus grandis×E.urophylla and Cunninghamia lanceolata as well as E.grandis and Pinus Massoniana were studied in this paper.The results showed that the artificial multi-storied mixed forest improved the growth increment and total mixed stand volume of Eucalyptus as well as single volume of Eucalyptus.The number and the growth of underground plant were improved also.Moreover,the artificial multi-storied mixed forest of Eucalyptus obviously improved the situation of soil physical and chemical characters and increased soil fertility in moisture,fertility,aeration and heat balance. |
