露天矿排土场植被恢复过程中种群生态位特征

Niche characteristics of main population in opencast dump vegetation restoration process

研究了阜新新邱露天矿排土场植被恢复过程中主要种群的生态位特征,结果表明:(1)在本研究区域内,猪毛菜(Artemisia scoparia)的生态位宽度最大,对资源的利用能力最强,对环境的适应性也是最强的。与伴生物种的重叠值也是很高的。但并没有出现明确的关系。(2)黄花蒿(Artemisia annua)与羊草(Aneurolepidium chinese),蒙古蒿(Artemisia mongolia)与早熟禾(Poa annua)之间的生态位重叠最高,说明它们对空间资源的利用效率比较高,能充分的利用资源。(3)猪毛菜(Artemisia scoparia)、黄花蒿(Artemisia annua)、蒙古蒿(Artemisia mongolia)同属于菊科草本植物,对环境的生存条件比较相似,所以它们存在较强的竞争关系。这些结论有助于了解生态恢复中的种群生态适应性。

This paper studies the niche characteristics of the main population in Fuxin Xinqiu Opencast Dump vegetation restoration process.The results show that in this study region,Artemisia scoparia niche breadth is the largest.Its resource utilization is most capable.Its environmental adaptability is the strongest.Associated species overlap with the value is high.But there has been no clear correlation;Artemisia annua and Aneurolepidium chinense,Artemisia mongolia and Poa annua niche overlap between high on their use of space resources more efficient,full utilization of resources;Artemisia scoparia,Artemisia annua,Artemisia mongolia belong to Compositae plants,the environmental conditions are similar to survival,so there exists strong competition.These findings help to understand the ecological restoration of ecological adaptability of the population.
