The invention discloses a method for calculating a solenopsis invicta situation area occurrence point, and the method comprises the steps: 1, constructing edges of to-be-processed points and processed points, constructing edges between the to-be-processed points, and setting the state of each point in a gathering point set where the processed points having edges with the to-be-processed points are located to be to be processed; 2, setting attribute degrees and values smaller than degree points for all the to-be-processed points, 3, constructing N aggregation point sets for all the to-be-processed points based on the attribute values of the degrees and the values smaller than the degree points, N being greater than or equal to 1, and each constructed aggregation point set being an effective point for calculating the ant situation occurrence area, the central point of the constructed aggregation point set and other points have edges, the numerical value of the attribute'degree 'of the central point is the maximum, and if a plurality of points with the maximum numerical value of the attribute'degree' exist, the point with the maximum value of the attribute'less than the degree point number 'is selected as the central point; and step 4, ending the method.
