摘　　要：以胶东地区引进树种雷登柏为研究对象,运用层次分析法构建以生长适应性、抗逆性、观赏性为主要指标的评价体系,对雷登柏进行生态适应性综合评价,以期为雷登柏在胶东地区的引种栽培和开发利用提供理论依据和技术支撑。结果表明:雷登柏的苗木保存率、年均树高生长量、年均地径生长量、年均冠幅生长量均显著高于本地同科乡土树种侧柏;苗木保存率、年均树高生长量、年均地径生长量均显著高于本地乡土树种黑松;抗涝性显著优于侧柏,抗病虫害能力显著优于黑松;雷登柏四季常绿,冠形优美,分枝匀称,观赏价值较高;雷登柏生态适应性综合评价指数为0.9632,生态适应性强,适宜在胶东地区荒山造林及园林景观绿化中推广应用。Taking the tree species Cupressus leighton Green introduced to eastern Shandong Province as the research object,an evaluation system with growth adaptability,stress resistance and ornamentality as main indicators was constructed by using the analytic hierarchy process(AHP)to comprehensively assess Cupressus leighton Green’s ecological adaptability.The research aimed to provide theoretical basis and technical support for introduction,cultivation,development and utilization of Cupressus leighton Green in eastern Shandong Province.Results showed that Cupressus leighton Green featured significantly larger seedling preservation rate,annual growth of tree height,ground diameter and crown width than Platycladus orientalis,a local native tree species of the same family;it had obviously bigger seedling preservation rate,annual growth of tree height and ground diameter than the local native tree species Pinus thunbergii;its waterlogging resistance was noticeably better than that of Platycladus orientalis,while its resistance to pests and diseases was greatly stronger than that of Pinus thunbergii;Cupressus leighton Green possessed high ornamental value,with the evergreen attribute,beautiful crown and symmetrical branches.The comprehensive evaluation index of ecological adaptability of Cupressus leighton Green was 0.9632,which indicated that it was strong in ecological adaptability and suitable for boosting application in afforestation and landscape greening for barren hills in eastern Shandong Province.
