研究区域石膏山位于太岳山国家森林公园的北端，是中国脱皮榆较为集中的分布区。基于2×2联列表，通过方差分析、χ2检验、Pearson相关系数、Spearman秩相关系数检验，对太岳山脱皮榆群落优势种的种间关联性进行研究。方差分析表明：脱皮榆群落的乔木层灌木层总体关联性均呈不显著相关，反映出该地区物种间虽存在一定的联系，但仍然存在独立的分布格局。不同检验结果表明：乔木层、灌木层绝大多数种对的联结关系未达到显著水平，种对间的独立性相对较强，这种种间联结的松散性可能与群落目前的发展阶段及物种本身的生态学特性有关，各群落正处于朝稳定方向发展的阶段。

The study area Shigao Mountain located in the northern end of National Forest Park in Taiyue Mountain, which is a concentrated distribution area ofUlmus lamellosa in China.Based on 2×2 contingency table,and by usingχ2-test,Pearson correlation coefficient and Spearman rank correlation,this paper studied the interspecific relationship of dominant species in U.lamellosa community in Taiyue Mountain.Variance analysis showed that the interspecific correlations of tree layer and shrub layer of U.lamellosa community were not significant.It reflected that there was a certain relationship between species in the region,but there were still independent distribution patterns.Different test results indicated that most species pairs in the tree layer and the shrub layer did not show significant association, which might be related to the serial stage of the forest and the ecological characteristics of the species.The forest was developing to the stable stage.
