平潭岛岩质海岸造林树种生长及适应性评价

为了积累基岩海岸生态恢复经验,改善沿海困难立地的生态环境,对平潭岛临海石质山体造林乔木和灌木树种的生长情况进行了调查,并对其适应性进行了分析。结果表明:岩质海岸不同乔木和灌木造林均表现出较高的保存率,其地径和树高生长比初植时均有显著提高,生态恢复成效显著;通过树种的适应性评判,4种乔木树种的适应性排序为木麻黄台湾相思肯氏南洋杉龙柏,4种灌木树种的适应性排序为黄栀子滨柃夹竹桃海桐。

Growth of Afforestation Tree Species and its Adaptability Evaluation in Rocky Coast of Pingtan Island

In order to accumulate the ecological restoration experience of the bedrock and to improve the ecological environment of the coastal hard site,the growth of species for trees and shrubs in the coastal forest of Pingtan Island was analyzed.Result shows that afforestation trees and shrubs all appear higher preservation rates on the rocky coast,and their ground diameter and tree height are significantly higher than those at early planting,and the ecological restoration effect is remarkable.Through the adaptability of the tree species,the descending order of adaptability of tree species is Casuarina equisetifolia>Acacia confusa>Araucaria cunninghamii>Sabina chinensis;the descending order of adaptability for four species of shrub species is Gardenia jasminoides>Eurya emarginata>Nerium indicum > Pittosporum tobira.
