摘要：为研究热带海岸地区不同更新方式的造林效果,选取3种阳性树种、3种中性树种和2种阴性树种在木麻黄沿海防护林内进行冠下更新造林,同时在邻近海防林的人工林采伐迹地进行植苗造林,并对2年后两种更新方式下不同造林树种的保存率、苗高和地径的生长情况进行对比分析。结果显示:3个阳性树种冠下更新造林和迹地更新造林均有较高保存率,其中除马占相思、苦楝在高郁闭度林冠下更新造林保存率分别为68%和76%,非洲楝迹地造林保存率76%,其他造林方式保存率均在80%以上。中生树种和阴性树种只有林冠更新造林能保证其存活和生长,迹地造林条件下仅小叶榄仁保存率达到15%,其余4种保存率均不足10%。对更新造林保存率最高的非洲楝、苦楝、马占相思和鸭脚木的生长进行分析得到,除马占相思高(2.16 m·a^(–1))、地径(3.05 cm·a^(–1))的年生长量迹地更新造林显著高于林冠下更新造林,其他3个树种均在中度郁闭(40%—55%)的林冠下更新造林生长效果最佳。以上研究为热带沿海地区更新造林方式和造林树种的选择提供依据。
In order to investigate the effects of different regeneration ways on afforestation, 3 light-demanding tree species, 3 neutral tree species and 2 shade-tolerant species were selected and planted in Casuarina equisetifolia coastal shelterbelt of different canopy density as well as in the logging slash in the northeast tropical coast of Hainan province. The comparative analysis of the survival rate and the growth of height and ground diameter after two years by different means of regeneration was taken. The result showed that the 3 light-demanding tree species could adapt to different environment condition with relatively high survival rates both in slash and under canopy. In most cases, the survival rates were over 80% except Acacia mangium （68%） and Melia azedarach （76%） in high canopy density and Khaya senegalensis （76%） in slash regeneration afforestation. As neutral tree species and shade-tolerant species got better survival rates under the canopy, only Terminalia mantaly had 15% survival rates when planted in slash, the survival rates of other 4 tree species were less than 10%. The results of growth of four tree species （Khaya senegalensis, Melia azedarach, Acacia mangium and Schefflera octophylla） showed that except that the annual height growth （2.16 m·a–1） and base diameter growth （3.05 cm·a–1） of Acacia mangium planted in the slash were significantly higher than those under canopy, the optimum growth effects of other three tree species were observed under the canopy with medium closure （40%-50%）.This study could provide the theoretical basis for the selection of tree species and the method of reforestation and regeneration in the tropical coastal area.
