| 摘 要： | 目的 为了解旅游发展对生态环境的影响，探究四川蒙顶山木荷Schima superba次生林群落对人为干扰的响应。 方法 在实地踏查的基础上，采用典型样地法对经轻度干扰、中度干扰和重度干扰的蒙顶山木荷次生林群落物种多样性和土壤理化性质进行研究。 结果 ①研究区共记录到维管植物155种，隶属72科115属；②人为干扰对该群落物种多样性水平产生负面影响，随着扰动强度的增加，物种丰富度指数(D)、Shannon-Wiener 多样性指数 (H)、Simpson 优势度指数(H′)和Pielou 均匀度指数(Jsw)均降低；③不同的土壤理化指标在不同干扰强度下具有不同的特征，人为干扰显著降低了土壤含水量和全氮、全钾、有效磷和有机质质量分数(P＜0.05)，增加了土壤容重，对土壤全磷、速效钾、pH没有显著影响(P＞0.05)；④土壤全钾、含水量、有机质是影响木荷次生林群落物种多样性的最重要因素。 结论 人为干扰对木荷次生林物种多样性水平、土壤理化性质的影响是负向的。图2表4参27

| Abstract: | Objective The objective of this study is to explore the impact of tourist development on the ecological environment and to investigate the response of the secondary forest community of Schima superba to human disturbance in Mengding Mountain, Sichuan Province. Method The species diversity and soil physiochemical properties of S. superba community with mild, moderate and severe human disturbance were studied using typical plot sampling. Result (1)A total of 155 species of vascular plants were recorded in the study area, belonging to 72 families and 115 genera. (2)Human disturbance had a negative impact on the level of species diversity in the community. With the increase of disturbance intensity, the species richness index (D) , the Shannon-Wiener diversity index (H), the Simpson diversity index (H′) and the Pielou index (Jsw) of S. superba community all decreased. (3)The soil physiochemical properties varied under different disturbance intensity. Human disturbance significantly reduced soil water content, total nitrogen, total potassium, available phosphorus, and soil organic matter mass fraction (P＜0.05), increased soil bulk density value, and had no significant effect on soil total phosphorus, available potassium and pH (P＞0.05). (4)Correlation studies showed that soil total potassium, water content and organic matter were the most important factors affecting the species diversity of S. superba community. Conclusion The impact of human disturbance on the biodiversity and soil physiochemical properties of S. superba community is negative. [Ch, 2 fig. 4 tab. 27 ref.] |
