| 摘 要： | 为揭示山西云顶山亚高山草甸植物群落优势种的种间关系,本研究通过种间联结性和相关性测定,对其植物群落13个优势种78个种对的种间关系进行研究。结果表明:13个优势种间大部分种对的种间关联不显著,种间联结不紧密,说明山西云顶山亚高山草甸植物群落结构不很稳定,存在一定程度的生态退化风险;多数原生优势种在群落中占据主要位置,同时也出现少数非原生优势种优势明显,有逐渐取代典型原生优势种的逆行演替趋势,这是由于人类频繁的旅游扰动所致。因此,应当合理的控制旅游开发强度与游客数量,保持亚高山草甸生态系统的稳定与自我维持,以持续高效的维持云顶山亚高山草甸的经济及生态价值。

| Abstract: | To reveal the interspecific relationship of dominant species of the subalpine meadow community in Yunding Mountain, Shanxi, the interspecific relationship of 78 species-pairs among 13 dominant species in the community was measured by interspecific association and correlation. The results showed that: the correlation associations of most species-pairs among the 13 dominant species were non-significant and loose, which illustrated that the community structure of the subalpine meadow in Yunding Mountain was unstable and faced the risk of ecological degradation. Most of the native dominant species occupied the major position in the community, but at the same time, a few of the non-native dominant species had obvious advantages, and there was a retrogressive succession tendency to replace the typical native dominant species, this was due to the frequent human disturbance caused by tourism. Thus, the intensity of tourism development and tourist number should be reasonably controlled, in order to keep the stability and self-sustaining of subalpine meadow ecosystem, and to efficiently maintain the economic and ecological value of subalpine meadow in Yunding Mountain. |
