Based on investigating and collecting information on the present situation of agro-ecological environment in Jing huiqu irrigation district of Shaanxi Province, soil samples are collected and the contents of heavy metals are analyzed. Meanwhile, soil environmental quality for heavy metals is evaluated by single factor index. Results show the average contents of Pb, Cd, Hg, As, Cu, and Zn in soils ar e 46. 0%, 105. 7%,90. 6%, 47. 8%, 12. 6%, and 178. 6%, respectively, higher than soil backg round values of Shaanxi Province.Only the content of Cr is similar basically. The variation coefficient of Cd is the biggest ( 1. 547) and that of A s is the smallest ( 0. 105) . There are no significant correlations among Pb, Cd, Hg, As, Cu, Zn,and Cr. The correlation between heavy metals and soil fertility index is not significant . The pollution degree of Zn is the highest and the average single factor index is 1. 48, which means pollution degree is at a light level.T he average single factor index of As is 1. 11 and it is also at a light level. The average single factor index of Cd is at no pollution level. The content s of Cr, Pb, Cu, and Hg are lower than the initial values of soil pollution accumulation basically .
