摘要: 为探讨克氏针茅草原植物群落物种间关联对不同放牧方式的响应,文章以中蒙边境两个苏木为例,选用X2检验、Jaccard关联指数、Spearman秩相关分析和Pearson相关系数对研究区内两个苏木的植物群落的优势种种间关联进行测定,结果表明:与蒙古国纳兰苏木相比,中国那仁宝拉格苏木草场的植物群落种间关系联结较为松散,种间存在一定的竞争、互斥现象;那仁宝拉格苏木植物群落内一年生植物比重增加,挤压原生多年生优势种生存空间;不同放牧方式对草原植物群落物种间关联产生重要影响,不合理的放牧方式可能导致草原种间失联,从而引起草原生态系统失衡。

关键词: 放牧方式;克氏针茅草原;植物种间关联

Abstract: In a case study of two townships at the China-Mongolia border,the chi-squared test,Jaccard correlation index,Spearman rank correlation analysis and Pearson correlation coefficient were used to determine the dominant interspecific associations of plant communities to explore the response of species associations in Stipa krylovii steppe to different grazing patterns.It was found that,compared with Nalan townships in Mongolia,the inter-species relationships between the plant communities of Narenbaolage townships in China were relatively few close,moreover,competition and mutual exclusion among species were observed to be greater in the Narenbaolage townships.The proportion of annual plants in the Narenbaolage townships was greater than in the Nalan townships,and the area of the perennial dominant species was reduced.Different grazing methods have an important impact on the inter-species associations of grassland plant communities,unreasonable grazing may lead to the loss of grassland species and imbalance of the grassland ecosystem.

Key words: Grazing patterns;Stipa krylovii steep;Inter-specific association of plant communities
