摘要:
对梵净山常绿阔叶林土壤螨类群落结构进行研究,以了解梵净山植被垂直基带的土壤螨类群落结构特征,对亚热带常绿阔叶林土壤螨类群落生态的研究具有重要意义。 2016 年12和2017年7月采用干漏斗法对梵净山常绿阔叶林带海拔600 m、800 m、1,000 m和1,200 m的土壤螨类进行了调查,共捕获土壤螨类8521头。结果显示:常绿阔叶林土壤螨类隶属3目91科176属,以Mixacarus和Scheloribates为优势属,螨类属数、个体数和个体密度均在1,000 m最高且冬季高于夏季;各海拔多样性指数和丰富度指数均较高,群落相似性程度总体不高,捕食性螨类群落结构主要为r-型,甲螨群落结构在类群结构上主要属O型,在个体数上主要为M型和P型。研究表明,与中国亚热带其它山地森林相比,梵净山常绿阔叶林土壤螨类类群更加丰富,土壤螨类属数、个体数和个体密度大致表现出随海拔升高呈先增加后减少的趋势,个体密度总体上具表聚性特征且冬季高于夏季,且三者在不同海拔和季节的差异均不明显,说明螨类群落结构受植被类型、小气候和人类活动等因素的综合影响。(图2表7参42)
Abstract:
Objectives: To understand the structure characteristics of soil mite’s community in the vegetation vertical basal zone of evergreen broad-leaved forest in Fanjingshan World Natural Heritage Nomination, it is significant to research the ecology of soil mites in subtropical evergreen broad-leaved forest. Methods: An investigation on soil mites were carried out in 600 m, 800 m, 1,000 m and 1,200 m in November 2016 and July 2017, they were picked up by Tullgren methods, a total of 8,521 individuals of soil mites, belonging to 3 orders, 91 families and 176 genera were collected, with Mixacarus and Scheloribates were dominant groups. Results: The highest group number, individual number and individual density of mites were found in 1,000 m, and the value of winter was higher than summer, there were higher diversity index and richness index of each elevation, but the lower degree of community similarity was found generally. The predatory mite community structures were found to be dominated by r- selection, the soil oribatid mite community structures were mainly O-type in the group structure, and mainly M-type and P-type in the structure of individual numbers. Conclusions: The research indicated that compared with other mountain forests of subtropical China, the soil mite groups in the evergreen broad-leaved forest of Fanjingshan were more abundant. The group number, individual number and individual density of mites showed the trend of increasing firstly and then decreasing with the altitude increasing, and individual density was characterized by the surface aggregation reflected the degree of winter was higher than summer, there was no significant difference among the three groups at different elevations and seasons, showing that the mite community structure is influenced by the factors such as vegetation types, microclimate and human activities, and the relationship with soil environmental factors need to be further explored.
