The community structures of Mesostigmata, Prostigmata, and Oribatida in the soil of broad-leaved regeneration forests and conifer plantations of various ages were assessed alongside soil and plant environmental variables using three response metrics (density, species richness, and species-abundance distribution). The density and species richness of mites recovered swiftly after clear-cutting or replanting. Oribatid mites dominated the soil mite communities in terms of densities and species richness for both forest types. Soil mite communities in broad-leaved forests was related to forest age, the crown tree communities index, and forest-floor litter weight. In contrast, soil mite communities in the conifer plantation sites were related to various indices of understory plants. The development of the understory plants was synchronized with the silvicultural schedules, including a closed canopy and thinning. Such a conifer plantation management may affect indirectly the community of mites.
采用密度、物种丰富度和物种多度分布这三种反应指标,评估了阔叶更新林和不同年龄的针叶林种植地土壤中的中气门目、前气门目和甲螨目(Oribatida)的群落结构,并结合土壤和植物环境变量进行了分析。在皆伐或重新造林后,螨的密度和物种丰富度迅速恢复。就密度和物种丰富度而言,两种森林类型的土壤螨群落都以甲螨目螨为主。阔叶林中的土壤螨群落与森林年龄、树冠树木群落指数和林下凋落物重量有关。相比之下,针叶林种植地的土壤螨群落与林下植物的各种指数有关。林下植物的发育与造林计划同步,包括树冠封闭和间伐。这种针叶林管理可能会间接影响螨类群落。
