Chinese loess is an important carrier of Quaternary paleoclimatic information and the grain size is one of its reliable proxy indicator.Previous studies involving Chinese loess grain size in the Quarternary have proposed:(1) the results of the loess grain size measurement are closely related to the differences from various pretreatment;(2) traditional parameters proxies are applied widely;(3) determination of sensitive grain size components is the key of precise reconstruction;(4) the frequency spectrum analysis of the grain size proxy time sequence is one of the important quantitative study methods of paleoclimate;(5) the grain size age model of loess-paleosol sequence is acceptable commenly for chronostratigraphy reconstruction.
