摘 要:
应用生态系统演替原理,选取青冈(Cyclobalanopsis glauca)、苦槠(Castanopsis sclerophylla)、白栎(Quercus fabri)、麻栎(Quer-cus acutissima)、小叶栎(Quercus chenii)、榔榆(Ulmus parvifolia)、紫楠(Phoebe sheareri)和薄叶润楠(Machilus leptophylla)8种乡土树种在安徽省马鞍山市南山铁矿排土场进行定植试验。定植后3 a小叶栎高度达(194.89±2.71)cm(平均值±标准误,下同),比移栽时增加119.89 cm,平均年增高39.96 cm,高度最小的紫楠也达(72.67±2.91)cm,比移栽时增加了62.67 cm,平均年增高20.89 cm;地径最大的榔榆已达(3.87±0.11)cm,最小的紫楠也达(1.27±0.15)cm,说明在人工管理条件下,这些植物生长良好。观测结果表明,落叶阔叶树种比常绿阔叶树种定植成活率高,株高和地径增长速度也较快,是该地自然群落恢复的重要候选树种。[著者文摘]

Abstract:
Following the principles of ecosystems succession, an experiment was conducted in the acidic wasteland of Nanshan Iron Mining, Maanshan City, Anhui Province, on establishment of eight native species of trees, i.e. Cyclobalanopsis glauca, Castanopsis sclerophylla, Quercus fabri, Quercus acutissima, Quercus chenii, Ulmus parifolia , Phoebe sheareri , and Machilus leptophylla. Three years after transplantation, Quercus chenii was found growing the fastest, reaching (194.89 ±2.71 ) cm in tallness, demonstrating a growth rate of 39.96 cm per year while Phoebe sheareri the slowest, being (72.67 ±2.91 ) cm with a growth rate of 20.89 cm per year. In terms of average ground diameter, Ulmus parvifolia ranked first, reaching ( 3.87 ± 0.11 ) cm, whereas Phoebe sheareri last, being ( 1.27 ± 0.15 ) cm. It is shown that these native species of trees can survive and grow up well in the acidic wasteland with some artificial assistance. In addition, broad-leaved deciduous trees are more adaptable to the experimental site than broad-leaved evergreen trees, and thought to be priority candidates to be used to restore native plant communities.[著者文摘]
