摘要

森林工程的目标之一是研究车辆与土壤之间的相互作用,并将可能对土壤造成的破坏降低到可接受的水平。本研究旨在分析 6 轮搬运车对低地土壤--假葛雷--水物理土壤特性的影响。研究使用了 17 吨的 Timberjack 1710B 转运车,该车转运了 694.1 立方米的橡树(栎树)货物。在装载的转运车经过八次转运后,每次都对土壤特性进行了测量。表层测得的体积密度范围为 1.01-1.23 (Me=1.10) g/cm3(未扰动土壤);1.14-1.70 g/cm3(装载转运车多次通过)。在装载转运车第一次通过后,观察到土壤密度增加最高(16%)。土壤固相介于 2.49 至 2.73 g/cm3 之间,未扰动土壤与多次通过转运车后的土壤在统计上没有显著差异。在装载转运车首次通过后,观察到孔隙度下降幅度最大(10%)。装载转运车首次通过后,土壤保水能力下降幅度最大(3%)。与未受干扰的林地土壤相比,装载转运车首次通过后观察到的土壤空气容量降幅最大(30%)。

Soil Characteristics in Oak Lowland Stand
The behavior of the vehicle-soil interaction and reduction of the possible soil damage to an acceptable level is one of the goals of forest engineering. This study aimed to analyze the impact of a 6-wheeled forwarder on water-physical soil characteristics on lowland soil – pseudogley. The research was conducted using a 17-ton Timberjack 1710B forwarder, which forwarded 694.1 m3 volume of oak (Quercus robur L.) assortments. Soil characteristics were measured after each of the eight passes of the loaded forwarder. Bulk density measured on the surface layer ranged from 1.01–1.23 (Me=1.10) g/cm3 (undisturbed soil); 1.14–1.70 g/cm3 (multiple passes of the loaded forwarder). The highest soil density increase was observed after the first pass of the loaded forwarder (16%). Soil solid phase ranged from 2.49 to 2.73 g/cm3 with no statistically significant difference between undisturbed soil and soil after multiple passes of the vehicle. The highest porosity decrease was observed after the first pass of the loaded forwarder (10%). The highest soil water retention capacity decrease was observed after the first pass of the loaded forwarder (3%). The highest soil air capacity decrease was observed after the first pass of the loaded forwarder (30%) compared to the undisturbed soil of the forest stand.
