厦门生态风景林景观改造树种生长状况调查与分析

Investigation on Growth of Transformed-Landscaping Trees of Ecological Landscaping Forest in Xiamen City

通过对厦门城市生态风景林景观改造树种效果的调查,结果表明:香樟与海南蒲桃带状混交造林胸径与树高的生长方面存在显著性的差异,香樟生长适应性强、长势好,海南蒲桃表现一般。块状混交造林树种生长适应性从强到弱依次为南洋楹>香樟>刺桐>高山榕>木棉。从整体分析及样地调查来看,南洋楹、香樟混交造林长势较好,可以推广应用,刺桐表现一般,高山榕和木棉表现较差。3种造林方式中树高不存在显著差异性,带状混交造林方式与带状纯林、块状混交在胸径生长水平上存在显著性差异。

Based on the investigation of the effect of transformed-landscaping tree species in Xiamen urban ecological landscape forest, result shows that there is a significant difference in the growth of DBH and tree height between the mixed by strip afforestation of Linnamomum camphora and Syzygium hainanense Chang et Miau, and the growth adaptability and growth of Linnamomum camphora is optimal, Syzygium hainanense Chang et Miau perform in general. The growth adaptability of block mixed afforestation tree species from strong to weak is Albizia falcataria〉 Cinnamomum camphora〉Erythrina variegata〉Ficus heterophylla 〉Bombax malabaricum . From the overall analysis ＆ plot survey, the mixed afforestation of Albizia falcataria and Cinnamomum camphora is optimal, and can be promoted and applied. The performance of Erythrina variegata is general, and Ficus heterophylla and Bombax malabaricum perform poorly. There is no significant difference in tree height among the three afforestation methods. There is a significant difference in the growth of DBH between the mixed forestation method and the strip pure forest and mixture by group.
