Wind erosion is a geomorphic process in arid and semi-arid areas and has substantial implications for regional climate and *** the Columbia Plateau of northwestern United States,the emissions from fine particles of loessial soils often contribute to the exceedance of inhalable particulate matter(PM)with an aerodynamic diameter of 10μm or less(PM10)according to the air quality ***,little is known about the threshold friction velocity(TFV)for particles of different sizes that comprise these *** this study,soil samples of two representative soil types(warden sandy loam and Ritzville silt loam)collected from the Columbia Plateau were sieved to seven particle size fractions,and an experiment was then conducted to determine the relationship between TFV and particle size *** results revealed that soil particle size significantly affected the initiation of soil movement and TFV;TFV ranged 0.304-0.844 and 0.249-0.739 m/s for different particle size fractions of Ritzville silt loam and warden sandy loam,***10 and total suspended particulates(TSP)emissions from a bed of 63-90μm soil particles were markedly higher for warden sandy loam than for Ritzville silt *** with the lower TFV of warden sandy loam,dust emissions from fine particles(warden sandy loam thus may be a main contributor to dust in the region's atmosphere,since the PM10 emissions from the soil erosion surfaces and its ensuing suspension within the atmosphere constitute an essential process of soil erosion in the Columbia *** and implementing strategic land management practices on sandy loam soils is therefore necessary to control dust emissions in the Columbia Plateau.
