通常，在意大利，矮林利用包括砍伐约80-85%的地上木质生物量，释放分散的标准（约40-120标准/公顷）。这是森林管理中的一项关键操作，对林下植被、动物群和土壤也有重要影响。本研究的目的是调查所产生的影响，规定的造林处理和伐木方法对土壤特性，板栗矮林与标准位于意大利中部的Cimini山区。本研究对标准化经营的矮林在板栗林土壤生态系统中的应用进行了研究，并对其应用效果和存在的问题进行了探讨。本研究还包括设备和工作方法的应用，以评估对森林土壤特性的影响实体。为了研究造林处理和伐木对森林土壤的影响，除了通常的物理和化学分析（pH值，有机质，容重，土壤容重和抗剪切力），土壤质量估计的生物指数的基础上土壤微型节肢动物（QBS-ar）。我们的研究结果表明，物理，化学和生物土壤特征可以强烈影响收获作业，因此，某些土壤过程可能会受到影响，在施加压实水平。另一方面，在土壤的收获，物理，化学和生物土壤特性的影响没有表现出类似的值的矮林林成熟阶段。结果证实，栗树矮林土壤具有土壤动物多样性水平高、结构良好、成熟的微型节肢动物群落的特征，是典型的稳定生态系统（QBS-ar值>200）。
Commonly, in Italy coppice utilization consists in a felling of about 80–85% of the above-ground woody biomass, with release of scattered standards (about 40–120 standard/ha). This is a crucial operation in forest management, which also has important effects on understory, fauna, and soil. The aim of this study is to investigate the impact generated by the prescribed silvicultural treatment and by the logging methodology on the soil characteristics, within the chestnut coppice with standards located in central Italy on the Cimini Mountain area. This study has paid close attention to the application of the coppice with standards management to the soil ecosystem of chestnut woods, with special regards to its utilizations and problems. The applicative use of equipment and working methods were also included in this study to evaluate the entity of impact on forest soil characteristics. For the study of the silvicultural treatment and logging impacts on the forest soils in addition to the usual physical and chemical analysis (pH, organic matter, bulk density, penetrometric and shear resistance), soil quality was estimated by means of a biological index based on soil microarthropod (QBS-ar). Our findings demonstrate that physical, chemical and biological soil features can be strongly impacted by harvesting operations and, consequently, certain soil processes may be influenced at the imposed compaction levels. On other hand, in the areas where soils were not impacted by harvesting, physical, chemical and biological soil features showed values similar to the mature stages of coppice stands. The results confirm that chestnut coppice soils are characterized by high biodiversity level of edaphic fauna and from a well-structured and mature microarthropod community, which is typical of stable ecosystems (QBS-ar value >200).
