This article makes an abstraction of the transportation network in Jiangsu province,a town connecting network model and a bus route network model are both established here.Complex network,graph theory and related tehories used to analyse the topological structure of the two models.By calculating and analysing the static parameters of two models,we can find topological properties of different models;at last,we study the antidestroying ability of two models.We hope it can provide some new references for the road construction and development of Jiangsu province from another angle.
