摘要:湿地植物物种多样性对于维护湿地生态系统的结构和功能至关重要。湿地土壤的生态环境变化可能会对其植被类型和生物多样性造成影响。为了解陕西汉中朱鹮国家级自然保护区的湿地植物物种多样性现状,以及不同干扰强度下土壤理化性状对湿地植物多样性的影响,本研究于2022年7-8月选择植物生长旺盛期在该保护区进行植物和土壤的实地调查。使用重要值(IV)确定保护区内的优势种,并利用丰富度指数(Patrick指数)、均匀度指数(Pielou指数)、香农指数(Shannon指数)和辛普森指数(Simpson指数)对物种多样性进行评估。同时,测定了土壤主要理化性质,如土壤全碳、全氮、全磷、有机质、pH、含水率和盐度,以探索它们与植物物种多样性的关系。结果显示,保护区内共有植物82种,隶属于30科61属,以草本植物为主。核心区与缓冲区在Shannon指数和Simpson指数上表现出较高的多样性值,而整个研究区的Pielou指数差异不显著。总体而言,植物物种多样性与土壤理化性质间的相关性不强。
Plant species diversity is crucial for maintaining the structure and function of wetlands.Changes of wetland soil may affect vegetation type and biodiversity.To gain a deeper understanding of the current state of plant species diversity in the wetlands of the Hanzhong Crested Ibis National Nature Reserve in Shaanxi Province and the effects of soil physicochemical properties on wetland plant diversity under different disturbance intensities,we conducted a field survey of plants and soil during the peak period of plant growth from July to August 2022.The impor?tance value(IV)was used to identify the dominant species in the reserve.Species diversity was assessed using the Patrick abundance index,Pielou evenness index,Shannon index,and Simpson index.Additionally,key soil physicochemical properties,such as total carbon,nitrogen,phosphorus,organic matter,pH,moisture content,and salinity,were measured.The results showed that there were 82 plant species,belonging to 61 genera of 30 families,mainly herbaceous plants.The core area and the buffer zone demonstrated higher diversity values in the Shannon and Simpson indices,while differences in the Pielou index across the entire study area were not significant.Overall,the correlation between plant species diversity and soil physicochemical properties in the sampling sites was weak.
