摘要

摘要本研究旨在确定影响公园生态步道内灰色森林土壤物理性质的定量和相关指标,以反映自然恢复过程中密实土壤的变化。在三维圆柱体的帮助下,进行了3次重复的物理性质测定,然后计算了它们的密度和孔隙率。采用5次重复的单块法测定灰色森林土壤上0.5 m层的生理活性根种群。研究发现,在人为践踏的影响下,研究的物理指标在灰色森林土壤上部10cm层的退化变化最大。土壤密度增加32.1 ~ 38.0%,固形物含量增加14.1 ~ 22.8%,孔隙体积减少32.0 ~ 44.3%,木本植物生理活性根质量减少84.6 ~ 91.2%。土壤的自然恢复主要发生在5 cm以上的土层。同时,在15年的时间里,观察到以下变化:密度下降了19.5%,固体颗粒含量下降了9.9%,孔隙含量增加了39.1%,生理活性根木本植物增加了330.0%。人为压实灰色森林土壤物理性质的定量和相关指标解释了生长在人为压实土壤中心的落叶木本植物生理活性根系质量的变化。

The influence of anthropogenic trampling of gray forest soils on their physical properties
Abstract The purpose of the study was to determine quantitative and relative indicators that significantly affect the physical properties of gray forest soils within the park ecological trail, to show changes in the compacted soil during natural recovery. Physical properties were determined in 3-fold repetition with the help of three-dimensional cylinders, followed by the calculation of their density and porosity. Population of physiologically active roots of the upper 0.5-meter layer of gray forest soils was determined by the monolith method in 5-fold repetition. It was found out that under the influence of anthropogenic trampling, the greatest degradation changes of the studied physical indicators are manifested in the upper 10-centimeter layer of gray forest soils. An increase in the density by 32.1–38.0% and solids content of the soil by 14.1–22.8%, as well as a decrease in the volume of pores by 32.0–44.3% was recorded and mass of physiologically active roots of woody plants by 84.6–91.2%. The natural restoration of soil occurs most intensively in the upper 5-cm layer. At the same time, over a 15-year period, the following changes were observed – a decrease in density by 19.5%, the content of solid particles by 9.9%, an increase in the content of pores by 39.1% and physiologically active roots woody plants by 330.0%. Quantitative and relative indicators of their physical properties obtained for anthropogenically compacted gray forest soils explain the changes in the mass of physiologically active roots of deciduous woody plants that grow in the centers with anthropogenically compacted soils.
