The present invention adopts inverse distance weight to utilize shaft tower bird pest historical failure data to carry out GIS interpolation analysis, the interpolation method that inverse distance weight is is weight with the distance between interpolation point and sample point, the weight of the sample point imparting that interpolation point is nearer is larger, and its weight contribution and distance are inversely proportional to and can be expressed as:
Z = Σ i = 1 n 1 ( D i ) p Z i Σ i = 1 n 1 ( D i ) p
Wherein Z is interpolation point estimated value, Zi (i=1+n) is actual measurement sample value, n is the actual measurement sample number participating in calculating, Di is the distance between interpolation point and i-th website, p is the power of distance, the result of its appreciable impact interpolation, its choice criteria is minimum average B configuration absolute error. when getting p=2, be namely called anti-square distance weighted method.
Table two is the bird pest Regional Risk grade classification principle table based on the bird pest fault frequency.The interpolation layer that the present invention generates carries out the division of bird pest risk class according to the principle described by table two.
When concrete generation, carry out interpolation according to known shaft tower fault frequency sample and generate corresponding layer, then according to the principle of table two, grade classification is carried out to layer, obtain the bird pest thematic map relating to the bird fault frequency based on overhead line structures.
