摘要:
本文采用方差比率法(VR)、χ2检验、联结系数(AC)、共同出现百分率(PC)、Pearson相关系数、Spearman秩相关系数以及M.Godron稳定性测定等数量分析方法,对山西稷山矮牡丹(Paeonia suffruticosa Andr. var. spontanea)生存群落中20个优势物种、190个种对间进行种间相关性及群落稳定性进行了分析。结果表明:(1)稷山矮牡丹生存群落20个优势种种群整体表现为不显著负相关性,物种间相对独立,群落稳定性结果(40/60)远离20/80,整体群落不稳定。(2)χ2检验中不显著关联的对数有168对,占到了88.78%;联结系数AC和共同出现百分率PC结果都表明20个优势种群落有很大的独立性或随机性,对生境的需求不同,共同出现概率较低;χ2检验结果、Pearson相关系数半矩阵图、Spearman秩相关系数半矩阵图分别表明检验呈正关联的种对占总对数的38.42%、38.42%、44.74%;检验呈负关联的种对分别占总对数的61.05%、61.05%,54.74%;其中黄刺玫(Rosa xanthina)、连翘(Forsythia suspensa)、辽东栎(Quercus wutaishanica Mayr)与矮牡丹的正相关性相对较显著;黄精(Polygonatum sibiricum)、红柄白鹃梅(Exochorda giraldii)、西北栒子(Cotoneaster zabelii)和黄栌(Cotinus coggygria)与矮牡丹的负相关性相对较显著;(3)根据种群的聚类分析和种间联结测定分析,把矮牡丹生存群落的20个优势种划分为3个生态种组。通过以上研究:该群落中种对间的关联性较弱,群落处于不稳定演替阶段,应该对矮牡丹保护的同时加强与其正相关性较强物种在其群落中的保护和建立,促进其群落趋于稳定,以求达到对其实效保护的目的。
Abstract:
To explore the interspecific association and community stability among the 20 dominant species, 190 species pair of Paeonia suffruticosa Andr. var. Spontanea communities by using quantitative analysis methods of variance ratio (VR), Chi-square test, association coefficient (AC), percentage co-occurrence (PC), Pearson correlation coefficient, Spearman rank correlation coefficient and M.Godron stability analysis. Results: (1) No significantly negative correlation was observed in the 20 dominant species of Paeonia suffruticosa Andr. var. Spontanea communities as a whole, which suggested that the species were relatively independent. The result of community stability (40/60) was far from the value of 20/80, indicating that the whole community was unstable. (2) As indicated in the result of Chi-square test, non-significant association was found in the 168 species pair, accounting for 88.78%. The ratio of species pair with positive correlation determined by Chi-square test, Pearson correlation coefficient semi-matrix, and Spearman rank correlation coefficient semi-matrix was 38.42%, 38.42%, and 44.74%, respectively. The proportion of species pair with negative correlation investigated by the same method as above was 61.05%, 61.05%, and 54.74%, respectively. Relatively significant positive correlation was noted between the Rosa xanthina, Forsythia suspensa or Quercus wutaishanica Mayr and Paeonia suffruticosa Andr. var. Spontanea and r elatively distinct negative correlation was exhibited between Polygonatum sibiricum, Exochorda giraldii, Cotoneaster zabelii or Cotinus coggygria and Paeonia suffruticosa Andr. var. Spontanea. The results of both AC and PC revealed that there was considerable independence or randomness in the 20 dominant species communities, which meaned that the percentage of co-occurrence was lower due to the different requirements to habitat. (3) The 20 dominant species of Paeonia suffruticosa Andr. var. Spontanea communities were classified to 3 ecological species groups according to the measurement results of cluster analysis and interspecific association. Based on the researches mentioned above, we found that the correlation among the species pair of this community was relatively weak, indicating that the community was in unstable succession stage. The protection of the dwarf peony should be strengthened while the protection and establishment of the species with strong positive correlation in its community should be strengthened, and the community should be stabilized in order to achieve the purpose of effective protection.? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ??
