The aim was to compare the spatial different of nitrogen and phosphate fertilizer and livestock and poultry manure pollution load with the relatively uniform index system．The result indicates the influence of nitrogenous fertilizer outflow to the farmland environment: Pingdu, Huang Dao, Laoshan and the urban district were in level four (threaten seriously), and Chengyang and Jiaozhou were in the level three. The influence of Phosphate fertilizer outflow to farmland environment: Huangdao was in level four (threaten seriously), and Jiaozhou was in the level three.
