在前人工作的基础上 ,对武昌珞珈山植被的演替作了研究。结果表明 ,其主体植被类型小叶栎、马尾松林自 1 95 6年首次调查以来发生了很大变化 ,乔木层内小叶栎的份额基本未变 ( 级以上立木由 69.0 1 %略降为 67.4 6% ) ,而马尾松则由 2 1 .1 3%骤降至 5 .1 5 % ,小叶栎的高度和胸径增长速率大于后者。林下灌木层和草本层明显消退 ,常绿阔叶树已侵入林中。武昌珞珈山植被由 1 92 8年全面绿化前的草丛和灌草丛 ,经人工栽培而成为马尾松、小叶栎混交林和少量针叶林 ,1 962～ 1 964年已发展到 2 1群系。与现存的 2 0群系相比 ,植被类型变化最大的是亚热带竹林植被型、栽培植被型中的木本亚型、沼泽和水生植被的消失 ,灌丛草地大面积衰退 ;杂木林和人工针叶林面积有所增加。预计本区植被最终演替为亚热带常绿阔叶林。
Based on the previous work, the succession of the vegetation of Mount Luojia in Wuchang was studied. The results showed that the main vegetation types of Quercus mongolica and Pinus massoniana forest changed greatly since the first survey in 1995, and the proportion of Quercus variabilis in tree layer remained unchanged (the grade of stand was slightly reduced from 69.0 1% to 67.4 6% ), While the Pinus massoniana plunged from 21.1% to 5.11%, and the growth rate of Q. variabilis was higher than that of the latter. Undergrowth shrub layer and herb layer subsided significantly, evergreen broad-leaved trees have invaded the forest. The vegetation of Lojiaga Mountain in Wuchang consists of grassland and shrubs before full greening in 1928, and is the result of artificial cultivation of Pinus massoniana, Quercus mongolica mixed forest and a few coniferous forest. From 1962 to 1964, it has developed into 21 groups . Compared with the existing20groups, the most significant changes of vegetation types are the subtropical bamboo forest vegetation type, the woody subtype in cultivated vegetation type, the disappearance of swamp and aquatic vegetation and the large area decline of shrub grassland; Ye Lin area has increased. It is estimated that the ultimate succession of vegetation in this area is subtropical evergreen broad-leaved forest.
