摘　　要：土壤螨群落沿山地海拔梯度分布格局是生物地理学研究的重要内容,但是目前的研究主要关注土壤层中土壤螨群落,忽略了多样性更丰富的凋落物层.为了阐明凋落物层和土壤层中土壤螨群落沿海拔梯度的分布格局,于2021年5月在天目山沿海拔364.33~1476.29m的12个样地采集了凋落物层和土壤层中土壤螨样品.分析结果表明:(1)样品中共捕获土壤螨7172头,84种,优势物种为副小单翼甲螨,土壤螨群落物种数、个体数总体呈现先增后减趋势.(2)在凋落物层土壤螨的Margalef丰富度指数、Shannon-Weiner多样性指数和Simpson优势度指数沿海拔梯度变化显著,呈现单峰分布;而土壤层土壤螨的多样性指数沿海拔梯度变化不显著.表明凋落物层和土壤层土壤螨多样性沿海拔梯度的分布格局有所不同.建议在亚热带山地同时开展凋落物层与土壤层土壤动物多样性的海拔梯度分布研究,为山地土壤动物群落多样性对全球变化响应提供更丰富的基础数据.It is an important topic to clarify the distribution pattern of soil mites along the mountain altitudinal gradient in soil zoology research and is the core of the corresponding study on mountain soil fauna related to global changes.However,the current study mainly focused on soil mites in the soil layer,ignoring those that are more diverse in the litter layer,which were higher than that in the soil layer.To illustrate the distribution pattern of soil mites along the altitudinal gradient in both the litter layer and the soil layer,soil mite samples were analyzed from 12 sample plots along 364.33 m to 1476.29 m in Tianmu Mountain in May 2021.The results indicate that(1)A total of 7172 soil mite individuals with 84 species were captured,and the dominant species was Haplozetes paraminimicoma.Species diversity in the litter layer was significantly higher than that in the soil layer.(2)In the litter layer,the Margalef richness index,Shannon-Wiener diversity index and Simpson dominance index all varied significantly along the altitudinal gradient with a unimodal distribution,while each diversity index in the soil layer they did not vary significantly along the altitudinal gradient.The results of this study suggest that the distribution patterns of soil mite diversity along the altitudinal gradient differ between the litter layer and the soil layer.This suggests that a study on the altitudinal gradient of soil faunal diversity in both the litter layer and soil layers in subtropical mountains will provide richer basic data on the diversity of soil faunal communities in mountains corresponding to global changes.
