【摘要】 对河南省栓皮栎林主要树种的生态位宽度与重叠进行分析。结果表明栓皮栎种群的生态位宽度较大,尤其是在土壤厚度空间资源上利用的优势明显;栓皮栎与麻栎、小叶青冈栎的生态位重叠较大,但在总资源轴上具分异性与互补性,生态位重叠随资源轴数增加而减小,从而使得栓皮栎林具有一定的稳定性。指出今后研究应注重栓皮栎对土壤利用的功能及机理。

【Abstract】 This paper analyzed the niche breadth and overlap of the main population of Quercus variabilis forest in Henan Province.The results show that:The Q.variabilis population has the widest niche breadth,especially on the axis of soil depth,it dominantes on other species.There are large niche overlap between Q.variabilis and Q.acutissima or Q.glauca f. gracilis .But on all resources,their niche overlap are not large.Therefore,the Q.variabilis forest have certain stability.The paper also urged that the future research should be strengthened on the soil ultilizing ability and michanism of Q.variabilis population.
