Abstract: The author proposed and applied the method of calculating total agrochemical pollution, which is helpful to calculating agrochemical pollution intensity and studying its spatio-temporal changes between the East and the West in China at county level. The author selected Pingdu City in Shandong Province in East China and Yanchi County in the Ningxia Hui Autonomous Region in West China as examples, revealed the amount and change of agrochemical pollution in this two areas in 2000—2012, in order to provide a scientific basis for harmonious and sustainable development of agriculture between the East and the West in China. It was found that the cultivated land area, crop yield, chemical inputs and pollution amount of per unit cultivated land area of Pingdu were much higher than that of Yanchi; however, pollution amount of per unit crop yield of Yanchi was higher than that of Pingdu and both of them greatly reduced from 2000 to 2012. The implication was that the increase of crop production could be obtained without the increase of regional pollution, and pollution intensity could be reduced directly by reasonable utilization of chemical fertilizers and pesticides, recycling plastic film and so on, especially improving farmer’s awareness of environmental protection and the utilization of other production factors.
