Coupling Relationship Between New Urbanization and Impervious Surface in Jiangxi Province During 1988-2017
[Objective] The new urbanization level of Jiangxi Province was analyzed based on the impervious surface data
the pattern and trend of the new urbanization development in cities were studied in order to provide scientific support for the development of the new urbanization of Jiangxi Province.[Methods] By constructing a comprehensive index system according to population
economic and social development
urban space
the new urbanization level of each city in Jiangxi Province was analyzed during the period from 1988 to 2017
and then based on the data of urban impervious surface
the correlation changes between new urbanization level and impervious surface in different stages were studied
and a linear relationship model between them were built.[Results] Over the past 30 years
the urban impervious surface expanded significantly
and it presented a spatial pattern of "high-slightly high-middle-slightly low-low" density circle distribution. The level of new-type urbanization in Jiangxi Province exhibited a general trend of "high in the north and low in the south". The regional development of urbanization was uneven. The year of 2006 marked an abrupt change point of new-type urbanization level growth. Before and after the abrupt change point
the correlation between new-type urbanization level and impervious surface was different. The R2 value of linear fitting between the impervious surface and the new-type urbanization were both above 0.9
which showed that the data of impervious surface could better reflect the new urbanization level of each city.[Conclusion] There is a strong correlation between the impervious surface and the new-type urbanization level
so the new-type urbanization level of each city can be well reflected by using the impervious surface data
it may finally help to analyze the development trend of urbanization and promote regional urbanization research.
