摘要:
 以内蒙古达拉特旗境内库布齐沙漠东缘中和西林场的小叶杨林为研究对象,采用点格局分析方法,对小叶杨种群在不同发育阶段的单种格局和种内关系进行分析。结果表明,1)小叶杨作为单优势种的人工林树种单一,整个系统只存在乔木和草本,结构单一不利于群落的稳定;2)在沙漠环境中,小叶杨的单种分布格局以随机分布为主;3)小叶杨不同发育阶段的分布格局以随机分布为主,且不同发育阶段种群间存在较强的正相关性,自然环境对格局形成的影响很大。
Abstract:
Populus simonii plantations occurring in the easthern margin of Hobq Desert in Dalateqi,Inner Mongolia were used as the research objects to study the spatial distribution patterns and interspecific relationship in different developmental stages using point pattern analysis method.The results showed that 1) P.simonii was the single dominant species in the plantations,only arbor and herbaceous species occurred in the whole system,resulting in a simple species structure that was unfavorable for the.community stability.2) In the desert environment,the single species distribution pattern for P.simonii was random distribution.3) In different developmental stages,The spatial distribution pattern of P.simonii was dominated by random distribution.Relatively significant and positive correlationship was observed among different populations,indicating that the natural environment had significant influence on the formation of spatial pattern.
