J. Anhui Agric. Sci. 2021 49 13 55-59 ificance to the analysis of the water environment. In this paper,the sediment of Shiwuli River was sampled,and the distribution
characteristics of the chemical element were analyzed. It was found that the spatial distribution of most elements was mainly affected by the ac-
tion of parent material,and had no obvious correlation with the upper and lower reaches of the river;the distribution of elements such as CaO
and Nb was affected by fluvial processes;the contents of some elements were abnormally increased due to the pollution of human activities and
the migration of elements.
