摘要

Through the study on geochemical assessment for land quality in Xining-Ledu, the authors found that the soil fertility is moderate, the soil environment is cleanly and it is fit to develop modern agriculture. It also found the soil is not yet be contaminated by heavy metals along the Huangshui River where industry and agriculture developed, but the extractable metal content is heavier than other areas, and the soil environment are deteriorating, it should cause much attention. There are relations generally between the high content of fluorin and universal endemic fluorosis in these areas.
