摘要
在详细调查北京市彩叶树种资源的基础上,通过对黄垡苗圃近3年来引种成功的40种彩叶树种的观赏特性及生态习性进行周年观察与记录,运用层次分析法对其进行综合评价.结果表明：进行评价的40种彩叶树种分为4个等级,其中Ⅰ级（＞3.7）：综合应用价值最高的种类,共计7种;Ⅱ级（3.3～3.7）：综合应用价值高的种类,共计10种;Ⅲ级（3.0～3.3）：综合应用价值较高的种类,共计9种;Ⅳ级（＜3.0）：综合应用价值一般的种类,共计14种（每级不包括上限）.此研究填补了北京市彩叶树种应用的评价空白,又为合理开发利用彩叶树种资源提供参考.
Based on the detailed investigation of colored-leaf trees resources in Beijing, ornamental characteristics and ecological habit of 40 kinds of colored-leaf trees were annually observed and recorded which have been successfully introduced by Huangfa nursery in the recent 3 years. And then we evaluated them by AHP. The results showed that, the 40 colored-leaf trees were divided into 4 grades, the grade I （〉3.7） included 7 kinds of colored-leaf trees, had the highest comprehensive application value; grade ]][ （3.3-3.7） included 10 kinds of colored-leaf trees, had higher comprehensive application value; grade m （3.0-3.3） included 9 kinds of colored-leaf trees, had high comprehensive application value; grade 1V （〈3.0） included 14 kinds of colored-leaf trees, had common comprehensive application value （each level without limit）. This research fills the gap of the application of colored-leaf trees in Beijing and also provides reference for rational development and utilization of colored-leaf trees resources.
