  • A new distance attenuation model for land classification—comprehensive attenuation model was presented in order to improve the accuracy of attenuation distance.Based on the beeline distance attenuation model and the most short-circuit path attenuation model,this model introduces the threshold concept in the course of attenuation distance calculation.Application of threshold to attenuation distance calculation with the different calculation methods chosen according to different situation makes the result of classification more reasonable.The model was realized in the actual project of the land gradation and valuation system development in Dezhou city.The results show that this model accords more with actual situation compared with other models.
