摘　　要：为丰富青岛市山头绿地植物群落类型,解决其生态稳定性差和景观效果单一的问题,对青岛市城区、郊区和山区的88个木本植物群落进行了全面调查,并进行了Jaccard相似性与聚类分析,结果表明：群落Jaccard相似性系数在0.50以上的占总数的3.95%,大部分样地群落之间的相似性系数在0.10~0.49。其木本植物群落大致分为黑松群落、刺槐群落和赤松群落3个类型;而灌木层,尤其是山区群落灌木植物类型相对丰富。总体而言,青岛市木本植物群落在水平结构上差异显著,但内部结构相对单一,山区植物群落的树种结构可为城区山头绿地的改造提供借鉴。Based on the investigation of 88 quadrants of Qingdao, the woody plant communities of Qingdao were analyzed by Jaccard similarity and cluster analysis to enrich the community types of green hills in Qingdao and resolve the problems about the ecological stability difference and the effect of single landscape. The results showed that communities with Jaccard index over 0.50 accounted for 3.95% of the total, most of the similarity coefficients between communities ranged from 0.1 to 0.49. The cluster analysis based on important values of plants showed that the woody plant communities of Qingdao could be divided into 3 types, including Pinus thunbergii community, Robinia pseudoacacia community, Pinus densiflora community. The community types of mountain shrub layer were relatively abundant. But woody plant communities of Qingdao was obvious in the horizontal structure, and the inside structure was relatively simple. The species structure of plant communities in the mountains was meaningful for the transformation of green hills.
