THE CONTENTS OF MAJOR CHEMICAL COMPONENTS IN THE SOIL FROM THE TYPICAL XIASHU LOESS PROFILES IN THE MIDDLE AND LOWER REACHES OF CHANGJIANG RIVER

This paper reports the analytical results of major chemical components of 94 loess samples from the Xiashu loess profile in the middle and lower reaches of the Changjiang River, the major component contents and the weathering intensity of Xiashu loess were compared with those of Luochuan loess from Northwest China. The results show no obvious difference in the contents of major components in the different Xiashu loess profiles, but some difference in the contents of readily leaching elements of loess and the chemical weathering intensity of loess among the different Xiashu loess profiles.
