| 摘要: |
| 调查与白头翁共存的伴生植物种类、相似性、生活型、分布区类型等，探讨其生态适应性和地理分布规律，针对性地提出白头翁资源保护利用建议，以期为燕山地区白头翁种质资源的保护和利用提供参考。采用访问调查、路线调查和典型样地调查法，对燕山地区白头翁生境伴生植物进行调查与分析。燕山地区从冀东的秦皇岛地区到冀北的承德地区都有白头翁的分布，多生于向阳的山地草坡上，喜光、耐旱、适于阳生性环境。白头翁生境伴生植物共56科128属164种，主要优势科为菊科（Compositae）、豆科（Leguminosae）、禾本科（Gramineae）、蔷薇科（Rosaceae）、唇形科（Labiatae）、百合科（Liliaceae）、毛茛科（Ranunculaceae）、萝藦科（Asclepiadaceae）等，其中乔木共5科5属7种，灌木共22科38属46种，草本植物共35科85属111种。调查的各样地间相似系数普遍较低，说明燕山地区不同地区白头翁生境差别较大，其伴生植物具有多样性的特点。伴生植物属的分布区类型可分为14个，群落具有明显温带性质。燕山地区白头翁生境多样性及伴生植物的多样性，反映出燕山地区白头翁生态适应多样性特点，有利于其引种栽培。 |

| Abstract: |
| The purpose of this study is to provide a scientific basis for protection and sustainable utilization of Pulsatilla chinensis. Based on the detailed investigation into the associated plant resources combining with the interview， route survey and sampling survey methods， the species composition， structural characteristics， life form and regional components of associated plants of P. chinensis in the Yanshan area were investigated. The wild P. chinensis distributed on the sunny hillsides from Qinhuangdao to Chengde. There were 164 species of plants associated with P. chinensis， belonging to 56 families and 128 genera. The most representative families were Compositae， followed by Leguminosae， Gramineae， Rosaceae， Labiatae， Liliaceae， Ranunculaceae， and Asclepiadaceae. Among these associated plants， there were 5 families， 5 genera and 7 species of arbors， 22 families， 38 genera and 46 species of shrubs and 35 families， 85 genera and 111 species herbs. The similarity coefficient among various plots is generally low， which indicates that the habitats of P. chinensis in different regions of Yanshan are quite different， and its associated plants have diversity characteristics. The distribution area types of associated plant genera can be divided into 14， and the community has obvious temperate characteristics. Results of this study demonstrate that introduction and cultivation of P. chinensis in the Yanshan area are feasible and necessary. |
