Biota play major roles in soil function and are highly sensitive to any disturbances including land degradation. However, it is not fully understood which organisms and what parameters can be useful in assessing soil quality. To fill this research gap we searched for good indicators of changes in environmental quality that could help to assess land degradation. Next to indicators using physical and chemical parameters, biological agents can also provide a lot of information. To obtain such knowledge we compared the soil quality of former military sites, which differed mainly in the texture, nutrients and organic carbon content based on fauna and vegetation indices. Among the fauna indices were Collembola and Acari abundance, Soil Biological Quality index (QBS-ar), decomposition rate and feeding activity. The Ellenberg index was used as a vegetation indicator, in which the response to pH, nutrients, and moisture was analysed. The experiment was conducted at 2 former military sites in the Czech Republic. Site 2 was characterised by higher nutrient content and a more compact soil structure in comparison to site 1. It was found that almost all fauna and vegetation indices showed better soil quality in site 2. The significant changes were indicated by the Collembola abundance, QBS-ar index and feeding activity, as well as response to pH considering vegetation indicators. Finally, we conclude the usefulness of biological indicators for monitoring the quality of soil, which can be adopted when making decisions concerning land use.

微型节肢动物和植被作为土壤质量的生物指标在前军事设施的贫瘠沙地进行研究

生物群在土壤功能中发挥着重要作用，并且对包括土地退化在内的任何干扰都高度敏感。然而，尚不完全了解哪些生物和哪些参数可用于评估土壤质量。为了填补这一研究空白，我们寻找可以帮助评估土地退化的环境质量变化的良好指标。除了使用物理和化学参数的指标外，生物制剂还可以提供大量信息。为了获得这些知识，我们比较了前军事基地的土壤质量，其主要区别在于基于动植物指数的质地、养分和有机碳含量。动物群指数包括跳虫和螨虫丰度、土壤生物质量指数（QBS-ar）、分解率和摄食活动。Ellenberg 指数被用作植被指标，其中分析了对 pH 值、养分和水分的响应。该实验在捷克共和国的 2 个前军事基地进行。与站点 1 相比，站点 2 的特点是养分含量更高，土壤结构更紧凑。发现站点 2 中几乎所有的动植物指数都显示出更好的土壤质量。跳蚤丰度、QBS- 表明了显着的变化。 ar 指数和摄食活动，以及考虑植被指标对 pH 值的响应。最后，我们总结了生物指标对监测土壤质量的有用性，可以在做出有关土地利用的决策时采用。该实验在捷克共和国的 2 个前军事基地进行。与站点 1 相比，站点 2 的特点是养分含量更高，土壤结构更紧凑。发现站点 2 中几乎所有的动植物指数都显示出更好的土壤质量。跳蚤丰度、QBS- 表明了显着的变化。 ar 指数和摄食活动，以及考虑植被指标对 pH 值的响应。最后，我们总结了生物指标对监测土壤质量的有用性，可以在做出有关土地利用的决策时采用。该实验在捷克共和国的 2 个前军事基地进行。与站点 1 相比，站点 2 的特点是养分含量更高，土壤结构更紧凑。发现站点 2 中几乎所有的动植物指数都显示出更好的土壤质量。跳蚤丰度、QBS- 表明了显着的变化。 ar 指数和摄食活动，以及考虑植被指标对 pH 值的响应。最后，我们总结了生物指标对监测土壤质量的有用性，可以在做出有关土地利用的决策时采用。跳虫丰度、QBS-ar 指数和摄食活动以及考虑植被指标对 pH 值的响应表明了显着变化。最后，我们总结了生物指标对监测土壤质量的有用性，可以在做出有关土地利用的决策时采用。跳虫丰度、QBS-ar 指数和摄食活动以及考虑植被指标对 pH 值的响应表明了显着变化。最后，我们总结了生物指标对监测土壤质量的有用性，可以在做出有关土地利用的决策时采用。
