摘 要:
在野外调查取样的基础上,研究卡拉麦里山自然保护区西部沙漠准噶尔沙蒿(Artemisia songarica)群落物种组成和多样性特征,探讨群落与环境的关系并揭示关键影响因子。结果表明,准噶尔沙蒿群落结构和物种组成较简单,物种多样性和植株密度均较低,有机质和养分含量也偏低。相关性分析表明,全氮(TN)、全磷(TP)及坡度是影响物种多样性的主要因素。CCA排序分析进一步表明,TN和TP是影响群落物种分布的关键因子。因此,未来可以适当提高土壤N、P含量,以利于该区准噶尔沙蒿群落的稳定和健康发展。

摘 要:
Based on field survey and sampling, the species composition and diversity characteristics of Artemisia songarica communities in western desert of Karamori Mountain Nature Reserve were studied, the relationship between communities and environmental factors was discussed, and the main influencing factors were revealed. The results showed that the community structure and species composition were simple and the species diversity and individual plant density were both low; besides,the contents of soil organic matter and nutrient were also on low side. The correlation analysis indicated that the soil total nitrogen content(TN), total phosphorus content(TP) and slope of sampling plot were the main factors influencing species diversity. The CCA ordination further demonstrated that TN and TP were the key factors affecting species distribution in A.songarica communities. Consequently, the soil N and P contents should be enhanced properly so as to benefit the stability and healthy development of A. songarica communities in the study area.
