The invention discloses a nutrient flux accounting method and system in atmospheric wet sedimentation in a designated area, and the method comprises the steps: converting discrete nutrient concentration data obtained by a monitoring station into a continuous nutrient concentration spatial distribution diagram through employing an inverse distance weight method in consideration of the time and space differences of wet sedimentation, and calculating the nutrient flux of the atmospheric wet sedimentation in the designated area; and performing gridding treatment by combining the corresponding rainfall spatial distribution diagram and nutrient concentration spatial distribution diagram in the designated area, and calculating the nutrient flux in atmospheric wet sedimentation in the designated area according to a formula # imgabs0 #. According to the method, the nutrient flux in the atmospheric wet deposition of the area is calculated by simulating rainfall and nutrient concentration data obtained by a large number
