摘要
Based on agro-ecological geochemical survey of eastern Shandong Province, the authors divided Qingdao City into 4 types and 11 eco-geochemical areas for ecological environment status early warning. The result reveals that such elements in soil as P, OrgC, Ba, La, Ag, B, W, Ga, Ge and Co were accumulated significantly in the four years, and elements like N, Bi, Hg, Cd, Au, OrgC and Pb were accumulated remarkably in some places of the study area, and the acidification of soil (pH decrease) was observable. These data strongly suggest that much attention should be paid to the environment. According to the accumulation rate of elements in soil in the four years, the environment quality changes of soil was predicted, and some suggestions were put forward.
