Abstract:

After mechanical vehicles run on woodlands,they will destroy the vegetation on the surface of the woodland,compact the soil and leave tracks.In recent years,domestic and foreign experts and scholars have thoroughly studied the impact of mechanical compaction on soil and have achieved many results.The literature analysis method is used to briefly describe the impact of forestry vehicle operations on physical and chemical properties of soil,microorganisms,carbon storage and greenhouse gas emissions.The study statistically analyzes the experimental conditions,instruments and methods adopted by relevant research institutes at home and abroad from the end of the 20th century to the present.It summarizes the commonly used experimental equipment and programs.The analysis shows that the soil compaction caused by vehicle operation increases the soil bulk density,reduces the porosity and reduces the permeability.It also shows that the content of nutrients and chemical elements in the soil decreases to varying degrees.It proposes that in the future,an in-depth research should be carried out to study the different texture and morphological differentiation of soil and the influence of soil structure variation on vehicle passability.

Key words: forestry machinery, forest area operations, soil compaction, physical and chemical properties, forest ecology
