| 摘 要： | 目的] 探索八大公山国家级自然保护区生境和季节变化对土壤跳虫群落分布的影响，为自然保护区森林健康的评价和监测提供科学的理论依据。方法] 于2016年4月、7月和11月对该区青冈林、光皮桦林和栲树林的凋落物和土壤进行取样调查，采用Tullgren干漏斗法分离土壤跳虫，分析土壤跳虫群落结构和多样性与生境和季节变化的相关性。结果] 共捕获土壤跳虫3 785头，隶属于4目15科29属，其中优势类群为符䖴属、长䖴属、球角䖴属和棘䖴属，4属共占总个体数的71.08%。分析数据表明，土壤跳虫主要集中分布于凋落物层，其个体数、类群数、Shannon-Wiener多样性指数和Margalef丰富度指数大小顺序为青冈林>栲树林>光皮桦林，且主要类群与生境的土壤有机质、全氮呈显著正相关，与土壤全钾、pH 呈显著负相关。春季（4月）土壤跳虫类群数最多，Shannon-Wiener多样性指数、Pielou均匀度指数和Margalef丰富度指数均最高，群落结构最复杂；秋季个体数量最多，但丰富度最低。结论] 八大公山土壤跳虫群落结构与多样性受生境和季节变化影响显著，生境的植被类型与土壤理化性质共同决定土壤跳虫分布，保持地表植被多样性和保留凋落物对促进土壤跳虫多样性具有积极作用。

| Abstract: | Objective] In order to analysis the effects of habitat and seasonal variation on the structure and diversity of soil Collembolan community in Badagong Mountains National Nature Reserve, and provides basis for further evaluating and monitoring forest health in nature reserves. Method] The soil Collembolan from litter and soil layer of Fagus lucida forest, Betula luminifera forest and Castanopsis fargesii forest was collected by Tullgren dry funnel method in April, July and November 2016. Result] A total of 3 785 soil Collembolans were captured, belonging to 4 orders, 15 families and 29 genera. The dominant genera are Folsomia, Entomobrya, Hypogastrura and Onychiurus, accounting for 71.08% of the total individuals. Most of the soil Collembolan distributed in the litter layer. The quantity of genus, quantity of individual, the Shannon-Wiener diversity index and the Margalef richness index were in order of F. lucida forest > C. fargesii forest > B. luminifera forest. The dominant genus of soil Collembolan was significant and positively correlated with total soil organic matter and soil nitrogen, but negatively correlated with soil total potassium and pH value. The quantity of genus, the Shannon-Wiener diversity index, the Pielou evenness index and the Margalef richness index were the highest in spring (April), while the largest quantity of individuals but the lowest Margalef richness index in autumn (November). Conclusion] The structure and diversity of soil Collembolan community in Badagong Mountains National Nature Reserve are significantly affected by the seasonal variation and habitats. The vegetation types and soil physical and chemical properties of habitat shared the common distribution of soil Collembolan. Therefore, maintaining diversity of vegetation and preserving plant litter have a positive effect on promoting soil Collembolan diversity. |
