Abstract Urbanization fundamentally alters soil physiochemical properties, but little is known on how this human effect alters soil biota. Microarthropods are important bioindicators due to their sedentary life form and sensitivity to environmental changes. Taxonomic richness, abundance, diversity, distribution of microarthropod communities were investigated in three urban land use types, remnant forests, low maintenance grass, highly disturbed open spaces, and were compared to deciduous forest stands outside the city, that served as reference. In general, habitats with more disturbed soil decreased the diversity of mites and springtails compared to the native vegetation sites. The leaf litter layer both in reference and remnant forests benefited the microarthropods through providing food resources and favorable habitats. Among soil properties soil organic carbon and bulk density had significant effects on mites (Acarina), while for springtails (Collembola), soil pH and soil moisture were significant factors. Soil temperature was the common significant constrained variable for both mites and springtails. Our study highlighted the effects of anthropogenic activities, especially that of soil disturbance in cities and the importance of retaining natural vegetation patches in urban green spaces.

美国马里兰州巴尔的摩城市绿地土壤微节肢动物群落

摘要 城市化从根本上改变了土壤的理化特性，但人们对这种人类影响如何改变土壤生物群知之甚少。微节肢动物因其久坐不动的生命形式和对环境变化的敏感性而成为重要的生物指标。研究了残余森林、低维护草、高度干扰的开放空间三种城市土地利用类型中微节肢动物群落的分类丰富度、丰度、多样性和分布，并与城外落叶林进行了比较，作为参考。一般而言，与原生植被地点相比，土壤受到更多干扰的栖息地降低了螨虫和跳虫的多样性。参考森林和残余森林中的落叶层通过提供食物资源和有利的栖息地使微节肢动物受益。在土壤性质中，土壤有机碳和容重对螨类（螨类）有显着影响，而对于跳虫（Colembola），土壤 pH 值和土壤水分是显着影响因素。土壤温度是螨类和跳虫常见的显着约束变量。我们的研究强调了人为活动的影响，尤其是城市土壤扰动的影响，以及在城市绿地中保留天然植被斑块的重要性。
