| Due to differences in geographic location,development history and many other economic and environmental factors,the development of each city shows significant differences.The development of the city is influenced by the three factors of economy,environment and society.The process of urbanization is influenced by multivariate,and it is difficult to describe its development only through a few observation indicators.From the system point of view,no matter how complex the external performance of the system is,it will always be associated with its intrinsic characteristics.Therefore,it is necessary to analyze and study the urban economic environment system with the idea of systematic research,making objective and effective analysis and evaluation of the sustainability of the urban economy and environmental system.In this study,based on the statistical data of the economic and environmental systems in the process of urban development,we first make correlation analysis between the internal factors of different research objects,and use the model of hierarchical clustering to compare the development pattern between different cities.Next,it puts forward comprehensive indexes of the economy and environment to quantitatively calculate and analyze the sustainability of the urban development process,and makes the horizontal comparison and vertical comparison time on the sustainability with different research objects.In addition,because of the data loss in the system research and the huge and complex calculation results,the multi-statistical analysis method and the visualization tool are used to realize the numerical fitting and the visualization of the Air Quality Index.This research work clearly explains the correlations between urban development factors,objectively and effectively analyzes the sustainable development pattern of different urban economic environment systems,and makes important significance for the in-depth study of urban system sustainable development. |
