Disturbances play an essential role in the shaping of temporal and spatial heterogeneity in natural community structures. The aim of this study was to provide an assessment of the deadwood influence on the chemical and biochemical properties of soils in a landslide area. The samples used to determine soil properties were collected from the entire landslide area, with locations distributed on a regular grid (50 × 50 m). The soil samples were collected from directly under the logs, and background soil samples were taken 1 m from the deadwood logs. The effect of the deadwood decomposition process was visible in the total organic carbon (C) and nitrogen (N) content and microbial activity of the soil. An increase in the enzyme activity and microbial biomass of the soil from directly beneath the deadwood was noted. In this study, it was found that a greater stock of deadwood was present in the accumulation zone, which resulted in a stronger effect of the released components on the soil cover. In order to restore landslide soils, microbial activity can be effectively stimulated by leaving deadwood on the landslide surface.

波兰卡帕蒂山滑坡地区沉材分解对恢复土壤覆盖的影响

干扰在自然群落结构的时间和空间异质性塑造中起着至关重要的作用。这项研究的目的是评估滑坡地区沉木对土壤化学和生化特性的影响。用于确定土壤性质的样本是从整个滑坡区域收集的，位置分布在规则的网格（50×50 m）上。从原木下面直接采集土壤样品，从枯木原木采集1 m作为背景土壤样品。在土壤中总有机碳（C）和氮（N）含量以及微生物活性中，可以看到沉木分解过程的影响。从枯木正下方观察到土壤中酶活性和微生物生物量的增加。在这项研究中，据发现，在堆积区存在更多的枯木，这导致释放的成分对土壤覆盖的影响更大。为了恢复滑坡土壤，可以通过在滑坡表面留下沉木来有效地刺激微生物活动。
