Abstract

Abstract

This study aims to further understand different input ways of heavy metal elements into the agroecosystem and resultant soil pollution and to promote the sustainable development of agriculture in the Jianghan Plain. To this end, data were collected from the geochemical assessment project on the land quality of Honghu City from 2014 to 2019 and were studied as a whole. Then, this study conducted geochemical analyses of heavy metal elements such as Cr and Hg input via three ways, namely atmospheric dry and wet subsidence, irrigation water, and chemical fertilizers, and calculated the input amount of the heavy metal elements via each way. Based on these, this study explored the impacts of the three ways on land quality. The results are as follows:①The land quality in Honghu City is slightly affected by human activities; ②The total input flux of different elements differs greatly with the input ways, reflecting the differences in the heavy metal elements input via local agricultural activities; ③The annual input flux of heavy metal elements via irrigation water is relatively high, and irrigation water contributes the most to the heavy metal elements (except for Zn, Cr, and Pb) input to soil.
