摘要：日益多样化的树木引种迫切要求对外来树种的生态、经济和文化等多种价值进行综合评价,而建立科学的评价指标体系则是实现这一目标的关键。本文采用4层结构设计,从外来种的适应性、繁殖扩散、危害、观赏和经济价值等方面确定了综合评价的各项指标,并建立了一个多层次外来树种的生态经济综合评价指标体系,采用专家咨询的方法确定各级评价指标的权重,将综合评价结果划分等级且提出相关管理措施和栽培建议,并对北京市城区及其周边地区引种栽培的14种主要外来树种进行了综合评价与分级。结果表明:绒毛白蜡(Fraxinus velutina)、美国白蜡(Faxinus americana)、刺槐(Robinia pseudoacacia)、火炬树(Rhus typhina)等外来树种较适合在城市园林绿化栽培模式和生态林栽培模式中使用;绒毛白蜡(Fraxinus velutina)、欧美杨(Populus×euramericana)、铅笔柏(Juniperus virginiana)、薄壳山核桃(Carya illinoensis)等外来树种更适合在自然保护栽培模式中使用。
The increasing introduction of diverse exotic trees imposes an urgent need to comprehensively assess their ecological, economic, and cultural values, while establishing a scientific assessment index system is the key to achieve this goal. In this paper, a 4-level hierarchical structure design was adopted to determine the assessment indices about the adaptability, reproduction and spread, damage potential, and ornamental, economic, ecological, and cultural values of exotic tree species. Each of the indices at each level was scored, and a weight was given based on expert consultation to calculate its final score. The final score was then classified into three levels, and corresponding management measures were proposed. The assessment system was used to evaluate 14 exotic tree species in Beijing City and surrounding areas. It was indicated that Fraxinus velutina, Faxinus americana, Robinia pseudoacacia, and Rhus typhina were more suitable for urban and ecological plantings, while Fraxinus velutina, Populus × euramericana, Juniperus virginiana, and Carya illinoensis were more fitted for nature conservation plantings.
