青岛地区彩叶树种的综合评价研究

Comprehensive Evaluation of Colored-leaf Trees in Qingdao

为丰富青岛地区彩叶植物种类,探索基于层次分析法对引种到青岛地区的彩叶树种进行定性与定量评价的途径。以引种到青岛地区的34种彩叶树种为评价对象,通过2个生长季节的露地栽培试验,对其生物学特性、生态习性及观赏价值进行观测,利用层次分析法对上述树种进行综合评价研究。结果表明：34种彩叶树种根据综合评价分值高低共分为4个级别,Ⅰ级（〉4.0）为综合应用价值高的树种,共9种;Ⅱ级（3.5～4.0）为综合应用价值较高的树种,共10种;Ⅲ级（3.0～3.5）为综合应用价值一般的树种,共11种;Ⅳ级（〈3.0）为综合应用价值较低的树种,共4种。建议综合价值高的树种在青岛市园林景观工程中重点推广应用,本研究首次对青岛地区彩叶树种进行综合评价研究,可为合理开发利用彩叶树种提供一定的理论依据和参考。

The paper aims to broaden the colored- leaf tree species in Qingdao. For quantitatively andqualitatively assessing the colored- leaf trees, based on the Analytic Hierarchy Process（AHP）, 34 kinds ofcolored- leaf trees introduced in Qingdao were evaluated comprehensively. Biological features, ecologicalcharacteristics and ornamental values were observed and analyzed through 2 growing seasons＇ open fieldcultivation. The results showed that： the 34 kinds of colored-leaf trees were divided into 4 grades according tothe scores： grade Ⅰ（〉4.0） included 9 kinds of colored- leaf trees and had the highest comprehensiveapplication value, grade Ⅱ（3.5-4.0） contained 10 kinds of colored-leaf trees and had higher comprehensiveapplication value, grade Ⅲ（3.0- 3.5） comprised 11 kinds of colored- leaf trees and had commoncomprehensive application value, and grade Ⅳ（〈3.5） included 4 kinds of colored-leaf trees and had lowercomprehensive application value. Those colored-leaf trees which belonged to grade Ⅰ could be popularized inthe landscape engineering construction in Qingdao. Our research for the first time conducted thecomprehensive evaluation of colored- leaf trees in Qingdao and also provided basic references for rationaldevelopment and utilization of colored-leaf tree resources.
