Abstract: 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 玉(跃3.7) included 7 kinds of colored-leaf trees, had the highest comprehensive application value; grade 域(3.3-3.7) included 10 kinds of colored-leaf trees, had higher comprehensive application value; grade 芋(3.0-3.3) included 9 kinds of colored-leaf trees, had high comprehensive application value; grade 郁(约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.
