摘  要:
对太原市常绿针叶树的生态适应性进行研究,为太原市园林绿化树种的选择提供参考。应用层次分析法(AHP)对太原市12种常绿针叶树的生态适应性进行评价,依托5个评价指标,利用1-9标度法建立判断矩阵计算权重值。根据综合得分进行适应性评价与聚类分析,将树种划分为Ⅰ级(极适应)、Ⅱ级(适应)、Ⅲ级(较不适应)、Ⅳ级(不适应)、Ⅴ级(极不适应)。5个指标(冠势、干形、生长势、枝叶态势、虫害表现)入选太原市常绿针叶树生态适应性评价指标体系,权重值分别为0.395、0.068、0.333、0.113、0.091,适应性评价与聚类分析划分12种常绿针叶树为4个等级。太原市常绿针叶树Ⅰ级树种为圆柏、侧柏、白皮松,Ⅱ级树种为白杄、青杄、杜松,Ⅲ级树种为樟子松、华山松、油松,Ⅳ级树种为雪松、辽东冷杉、南方红豆杉。

摘  要:
In the research, we studied the ecological adaptability of evergreen conifers in Taiyuan City, and provided references for the selection of greening species. Analytic hierarchy process(AHP) was used to evaluate ecological adaptability of 12 evergreen conifers in Taiyuan, and based on the five evaluation indexes,the judgment matrix and weight value were established by 1-9 scale method. According the comprehensive scores, we conducted adaptability evaluation and cluster analysis, and the tree species were divided into five levels: level Ⅰ(extremely adaptive), level Ⅱ(adaptive), level Ⅲ(not very adaptive), level Ⅳ(not adaptive),level Ⅴ(extremely maladaptive). Five indicators(crown potential, trunk shape, growth potential, branches and leaves situational, pest performance) were chosen in the ecological adaptability evaluation index system of Taiyuan evergreen conifers, and the weight value of every indicator was 0.395, 0.068, 0.333, 0.113 and 0.091,respectively. The adaptability evaluation and cluster analysis showed that the 12 evergreen conifers were divided into four grades as: levelⅠ-Sabina chinensis, Platycladus orientalis, Pinus bungeana; level Ⅱ-Picea meyeri, Picea wilsonii, Juniperus rigida; level Ⅲ-Pinus sylvestris, Pinus armandii, Pinus tabuliformis; level Ⅳ-Cedrus deodara, Abies holophylla, Taxus chinensis.
