To evaluate the soil environmental quality of Qinghai agricultural origin being suitable for producing green food, the soil samples from main agricultural production environment in Ledu Coun-ty were collected, and test and analysis were conducted.On the basis of the environmental indica-tors and evaluation methods, the soil environmental quality were evaluated and analyzed.The results showed that:the single pollution index and comprehensive pollution index of the main origin of agri-cultural products in Ledu County soil are in line with state regulations of green agricultural produc-tion and environmental conditions requirement;individual potential ecological risk of heavy metals in the soil has minor ecological hazard and the composite index is in a low degree of ecological harm.
