| 摘 要： | 试验选用木麻黄4个优良无性系来改造低效防护林。试验表明,在海岸前沿基干林带改造中,采用隔行带状改造效果较好,木麻黄低效林经过改造,6 a后可以达到生长快、短期内恢复基干林带的目的。在后沿片林内通过采用木麻黄优良无性系等综合措施块状改造后的林分与保留老林带相比,除了平均胸径生长略低1.2 cm外,其保存率、树高和冠幅生长量显著高于保留低效林的51.17%、2.3%和25.71%。

| Abstract: | The experiments selecting Casuarina equisetifolia and other 3 superior clones to transform low-benefit protection forest were conducted.The results show that using interlacing strip transformation has the better effect.The goal of fast growing and restoration of main shelterbelt in short term is achieved after 6 years' transformation.The preserving rate,tree height,crown growth of the stands which have been block transformed by adopting measures(e.g.,using superior clones of Casuarina equisetifolia) on the behind greenbelts are 51.17%,2.3%,and 25.71% higher than CK(except 1.2cm lower than mean DBH) compared with remain-aged-belts. |
