摇蚊群落的组成和生态学意义，这种组合在泥炭地很少受到关注，特别是在亚热带高山地区。本文报道了中国中部亚热带三个亚高山泥炭地亚化石摇蚊的空间分布及其环境控制。在41个表层泥炭样品中发现44属62个形态型。这些分类群与同一地区的浅淡水湖泊中发现的不同，因为陆地/半陆地分类群在泥炭地摇蚊群落中很常见。在三个调查泥炭地之间观察到的差异，空间异质的微生境也表现出显着的差异，在特定的物种丰度，即使在同一泥炭地。重要的类群，与特定的泥炭地，和/或说明内泥炭地社区的差异，包括Tanytarsus pallidicornis-2型，这是与较低的电导率，andNeozavrelia，这是与更大的氧化还原电位和pH值。多元统计分析显示摇蚊群落组成和三个环境因素（电导率，氧化还原电位和pH值）之间的显着关系。泥炭地的人为影响和自生过程可能会通过泥炭地水文和化学的直接或间接变化来改变生物群落。二仙岩泥炭地低摇蚊数量和多样性可能反映了包括泥炭藓采集在内的强烈人类活动导致的生态退化。这项研究提供了有关亚热带泥炭地生物多样性的信息，并说明了利用亚化石摇蚊作为过去泥炭地水化学变化的代理。
The composition of Chironomidae communities and the ecological significance of such assemblages in peatlands have received little attention, especially in subtropical alpine regions. We report on the spatial distribution of subfossil chironomids and environmental controls on the insects in three subalpine peatlands from subtropical, central China. We found 44 genera and 62 morphotypes in 41 surficial peat samples. The taxa are different from those found in shallow freshwater lakes in the same region, as terrestrial/semi-terrestrial taxa are common in the peatland chironomid communities. Dissimilarities were observed among the three investigated peatlands, and spatially heterogeneous microhabitats also showed notable differences in particular species abundances, even within the same peatland. Important taxa that are associated with specific peatlands, and/or illustrate within-peatland community differences, includeTanytarsus pallidicornis-type 2, which is related to lower conductivity, andNeozavrelia, which is associated with greater redox potential and pH. Multivariate statistical analysis revealed significant relationships between chironomid community composition and three environmental factors (conductivity, redox potential and pH). Anthropogenic influences and autogenic processes in peatlands likely modify the biotic communities, either through direct or indirect changes in peatland hydrology and chemistry. Low chironomid concentrations and diversity in Erxianyan Peatland may reflect ecological degradation caused by intense human activities, including the harvest ofSphagnum. This study provides information about subtropical peatland biodiversity and illustrates the utility of subfossil chironomids as proxies for past hydro-chemical changes in peatlands.
