The group of soil arthropods known as Collembola is characterized by its abundance and sensitivity to environmental changes. They are ideal an species for soil indicators. In order to clarify the effects of species invasion and inundation on the Collembola community in coastal mudflat wetlands, the correlation between the collembolan functional traits and environmental factors was studied in Shanghai Jiuduansha Wetland National Nature Reserve for the first time. Five sample plots, including three vegetations- (an invasive species), , and -were set up following the differences in vegetation types and between high and low tidal flats. Data on the diversity of the Collembolan species and their functional traits were collected and combined with the soil physicochemical properties and vegetation environment factors in different tidal flats. The key findings and conclusions of the study are as follows: a total of 18 species, four families, and three orders make up the obtained Collembola, two species of are dominant species that account for 49.59% and 24.91% of the total, respectively. The maintenance of the species diversity of Collembola is disturbed by the higher conversion efficiency of rather than with lower organic carbon (C) content and higher total nitrogen (N) content. The primary environmental variables influencing species distribution were the C/N ratio, total N, and bulk soil density. The bulk density of the soil impacts the movement and dispersal of the functional traits. The depth of the soil layer is related to the functional traits of the sensory ability. The analysis of the functional traits and environment is fairly helpful in exploring how species respond to their environment and offers a better explanation for the habitat selection of Collembola.
被称为弹尾目的土壤节肢动物群体以其数量众多和对环境变化敏感为特征。它们是理想的土壤指示物种。为了阐明物种入侵和淹没对滨海泥滩湿地弹尾目群落的影响，首次在上海九段沙湿地国家级自然保护区研究了弹尾目功能性状与环境因子之间的相关性。根据植被类型以及高潮滩和低潮滩之间的差异，设置了五个样地，包括三种植被（一种入侵物种）。收集了弹尾目物种多样性及其功能性状的数据，并将其与不同潮滩的土壤理化性质和植被环境因子相结合。该研究的主要发现和结论如下：所获得的弹尾目共有18种、4科、3目，两种 为优势种，分别占总数的49.59%和24.91%。弹尾目物种多样性的维持受到 较高的转化效率的干扰，而不是 较低的有机碳（C）含量和较高的总氮（N）含量。影响物种分布的主要环境变量是碳氮比、总氮和土壤容重。土壤容重影响功能性状的移动和扩散。土壤层深度与感官能力的功能性状有关。对功能性状和环境的分析有助于探索物种如何响应其环境，并为弹尾目的栖息地选择提供更好的解释。
