For quantitatively and qualitativelyassessingthecolored-leaftrees,basedontheAnalyticHierarchyProcess(AHP), 34 kindsof colored-leaf trees introduced in Qingdao were evaluated comprehensively. Biological features, ecological characteristicsandornamentalvalueswereobservedandanalyzedthrough 2 growingseasons’openfield cultivation.Theresultsshowedthat:the34kindsofcolored-leaftreesweredividedinto4gradesaccordingto thescores:grade Ⅰ(＞4.0)included 9 kindsofcolored-leaftreesandhadthehighestcomprehensive applicationvalue,grade Ⅱ(3.5-4.0)contained 10kindsofcolored-leaftreesandhadhighercomprehensive application value, grade Ⅲ (3.0- 3.5) comprised 11 kinds of colored-leaf trees and had common comprehensiveapplicationvalue,andgrade Ⅳ(＜3.5)included 4 kindsofcolored-leaftreesandhadlower comprehensiveapplicationvalue.Thosecolored-leaftreeswhichbelongedtograde Ⅰcouldbepopularizedin the
