The main results of agro-ecological geochemical survey and evaluation of Weihai are introduced. Generally, the geochemical environment quality is good. Most elements or indexes of shallow groundwater are below the natural background concentration, and the concentration of Cd, Fe, NO₂^- and the total hardness in parts of shallow groundwater samples are over the drinking water standards. This shallow groundwater is not suitable for drinking. The existent ecological geochemical problems in this area are mainly: the pH value of soil is low in the hilly area, and the top soil has the developing trends into the strong acid and strong alkali, which will increase heavy metal element activation; the soils of coastal area are barren; the nutrition level of N, P and organic matters are usually in the lack level; the heavy metal pollution is serious in top soil of Rushan City and densely populated township, including Hg Cd Pb and Zn.  oft-com:office:office" />
