摘要

A series of metal sulfide deposits are developed in the lakeside area of the middle and lower reaches of the Yangtze River in China, of which copper-sul-fide deposits are one of them. Copper-sulfur mines will produce heavy metal pollution in the surround-ing soil,so the study of the enrichment law of heavy metal elements in the soil has important reference value for formulating reasonable heavy metal pollu-tion prevention and control measures. In this paper, taking copper-sulfur mines in the middle and lower reaches of the Yangtze River in China as an example, the tracer method was used to study the enrichment characteristics and sources of heavy metal pollution element copper in soil. Research results show that the sources of copper and sulfur in the soil in this area include copper-sulfur mine tailings, waste ore, organic and inorganic sulfur in the soil, and biologi-cal effects. The sulfur content in the soil around the copper-sulfur mine is close to the sulfur content of the ore by 20%~30%,indicating that the sulfur in the soil basically comes from tailings and waste ore; the copper content in the soil is also high, therefore, the pollution effect of the mine on the soil is obvious. The main sources of copper enrichment in the soil include acidic high-salinity water, water leaching the soil, and vegetation.Among them, acidic high-salin-ity water and water leaching of the soil are the main factors that cause copper enrichment in the soil, and the copper enrichment caused by the vegetation is relatively low.
