| Abstract: |
| The shadow areas of metropolis is a phenomenon of development gap formed
by the different combination of agglomeration and radiation among the central city and
its surrounding areas. This article reviewed a number of metropolitan shadow theories
regarding formation and evolution mechanisms. By using Huff model, K-means cluster and
spatial auto-correlation, this article defines the ranges of metropolitan shadow areas in
2012 in Beijing-Tianjin-Hebei (BTH) metropolitan region, and summarizes the method of
defining shadow area and semi shadow area by means of GIS spatial analysis. Results are
indicated as follows: by means of GIS spatial analysis, the metropolitan shadow area and
penumbra area can be defined quantitatively and intuitively. The metropolitan shadow areas
of BTH metropolitan exist in the northwestern and southwestern of Beijing City. The natural
background conditions and location differences determine the spatial disequilibrium of
population and economic activities, and the unbalanced regional development strategy has
led to the rapid agglomeration of population and industry into coastal areas such as Beijing
and Tianjin. Regional or local policy bias, transportation condition, economic factors and
industrial structure account for the formation of shadow area in BTH metropolitan regions.
To reduce the effects of metropolitan shadow, the centre city should optimize its regulation
and the shadow areas should adopt positive strategies. |
