摘要：Snow gliding is a key factor for snow-glideavalanche formation and soil erosion. This study considersatmospheric and snow variables, vegetation characteristics,and soil properties and determines their relevance for snowgliding at a test site (Wildkogel, Upper Pinzgau, Austria) during winter 2014/2015. The time-dependent data were collected at a high temporal resolution. In addition to conventional sensors, a “snow melt analyzer” was used.The analysis shows that the soil temperature 10 cm belowthe surface, the phytomass of mosses, the liquid water content in the snowpack, and the static friction coefficient of theglide shoes had significant influence on snow gliding duringthe whole winter. In the first period (October to January) thesoil moisture at the surface and 1.5 cm below the surface andthe length of the slope uphill of the glide shoes affected thesnow gliding, too. In the second period (February to May) thesoil temperature at the surface, the soil moisture 10 cm belowthe surface, and the slope angle had additional influence onsnow gliding.The role of the vegetation in the snow-glide process is determined by the influence on the static friction coefficientcaused by its composition and characteristics and by mossrich and short-stemmed canopies being seemingly more interconnected with the snowpack.In addition to the soil and snow properties, the topography and the vegetation characteristics, further investigationsmay be focused on the freezing and melting processes in theuppermost soil layers and at the soil surface.
