Oribatid mites are one of the numerically dominant arthropod groups in soils. They play an important role in soil food webs via regulating the decomposition of organic matter and propagating microorganisms within the soil. To our knowledge, the influence of different plant functional groups on oribatid mites has not been studied in abandoned farmland with undisturbed succession before. The density and assemblage structure of oribatid mites in nine grassy arable fallows relative to three habitat age classes (2–3, 6–8, 12–15 years) and three selected plant species (legume: Medicago sativa, forb: Taraxacum officinale, grass: Bromus sterilis) were investigated in soil associated with single plants. Mite density declined marginally not significant with habitat age because of high abundances of the ubiquitous species Tectocepheus velatus sarekensis and Punctoribates punctum in young and mid-aged fallows and their subsequent decline in old fallows. Oribatid mite density and species assemblage were not affected by plant species. Only P. punctum had significantly higher densities in B. sterilis samples than in T. officinale samples due to a higher amount of fine roots. Distance-based linear models revealed that 65% of the variation in mite assemblage was explained by soil properties, soil type, exposition and geographic position, while habitat age was of minor importance. Canonical correspondence analysis revealed that the mite assemblage was best explained by soil organic and microbial carbon, water content and pH.

休耕地的螨虫更容易受到土壤性质的影响，而不是栖息地年龄和植物种类的影响

Oribatid 螨是土壤中数量占优势的节肢动物群之一。它们通过调节土壤内有机物的分解和繁殖微生物，在土壤食物网中发挥重要作用。据我们所知，此前尚未在未受干扰演替的废弃农田中研究过不同植物功能群对甲螨的影响。九个休耕草地中甲螨的密度和组合结构，相对于三个生境年龄等级（2-3、6-8、12-15年）和三个选定的植物物种（豆科植物：苜蓿，草本植物：蒲公英，草本植物） ：在与单一植物相关的土壤中研究了无芒雀麦 (Bromus sterilis)。螨密度随着栖息地年龄的增长略有下降，但并不显着，因为年轻和中年休耕地中普遍存在的 Tectocepheus velatus sarekensis 和 Punctoribates punctum 物种丰度较高，而它们随后在老年休耕地中下降。国螨密度和物种组合不受植物物种的影响。由于细根数量较多，只有 P. punctum 在 B. sterilis 样品中的密度显着高于 T. officinale 样品中的密度。基于距离的线性模型显示，65% 的螨虫组合变化是由土壤特性、土壤类型、暴露和地理位置来解释的，而栖息地年龄的重要性次要。典型对应分析表明，土壤有机碳和微生物碳、含水量和 pH 值可以最好地解释螨虫组合。
