Abstract: The fundamental impetus of the development and evolution on accessibility is the results of the nonlinear correlation function between social, economic, resources and environment system (SERE) elements. For the inadequacies of the traditional accessibility evaluation model based on the shortest path and the narrow research perspectives，this paper sets up an evaluation index system of comprehensive accessibility and SERE coupled system, reconstructs the accessibility model based on the shortest transit time, introduces the coupling-coordination degree model in order to reveal the space-time patterns and the evolution mechanism of township comprehensive accessibility(TCA) with the help of urban-rural road network space database from 2000 to 2014 in Jingzhou:①TCA in Jingzhou is well developed, following Gaussian distributions and showing a certain randomness;②TCA is irregular circles distributed round the city center which caused by the combination of center location preference, the Jingjiang River “natural moat” role and the two high-speed traffic;③ The global spatial autocorrelation of coupled coordination between township TCA and SERE has a weak positive correlation, but the local spatial correlation function is complex, the four basic types are showing a aggregated distribution;④The coupled coordination degree between township TCA and SERE is continuous optimization, but there has a significant traffic lag development, at the same time, the spatial variation is obvious, overall showing a spatial heterogeneity with high coupling degree and low coordination degree.
