%X Upon the exploration and research in the field,we determined the content of Pb,Zn,Cu,Mn,Cr,Co,Ni,Ti,V,Nb at YPC loess-soil site on the X-ray Fluorescence.In the stage of loess accumulation,the content of these heavy metals are very low and the variances are very little,which can be served as the background value of paleosol formation.In the stage of Holocene Megathermal,the content of these heavy metals are increased greatly,because the eluviations and transmigrations of freely soluble elements under warm and humidity environment.In the stage of modern soil(MS),the content of Pb are increased gradually,and there are abruptly increase in the depth of 8cm below the ground,which are the records of sedimentation and accumulation of atmospheric pollutant.
