Evaluation Method of Urban Vitality Based on Minimum Accumulated Resistance Model——A Case Study of Nanchang City
The study of urban vitality plays a positive role in evaluating urban development,con-struction and planning.When the traditional method is used to evaluate the comprehensive urban vi-tality,the difference between the suburban,exurb and rural areas is not high,and the difference is not highlighted.In this paper,Minimal Cumulative Resistance Model(MCRM)is adopted to con-struct economic corridor for distance weighting,and Topsis method is improved based on weighted generalized Markov distance and distance weighting to evaluate the comprehensive vitality of cities.Taking the comprehensive vitality evaluation of Nanchang city as an example,the research is carried out.The comparison results show that compared with the entropy weight method and the traditional Topsis method,the improved Topsis method has a significant improvement effect on the suburban vi-tality value,which makes the suburban evaluation results more consistent with the actual situation.
