西宁—乐都地区土地质量地球化学评估

通过对西宁—乐都地区的土地质量地球化学评估发现,该地区土壤肥力适中,土壤环境清洁,适宜发展现代农牧业。同时,也发现沿湟水河工农业发达的地区,土壤中重金属元素虽还未达到引起污染的程度,但其含量要高于其他地区,土壤环境有恶化趋势,应引起相当的重视。当地土壤中普遍高F可能与当地较普遍的地方性F中毒有一定联系。

The Geochemical Assessment for Land Quality in Xining-Ledu Area

Through the study on geochemical assessment for land quality in Xining-Ledu, we 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 envi- ronment are deteriorating, it should cause much attention. There are relations generally between the high content of fluorin and universal endemic fluorosis in these areas.
