Urban Land Carrying Capacity Evaluation of Wuhan City with Geographically Weighted Techniques
urban land resource has become a key part in urban development
and attracted more and more attentions. However
global methods were traditionally adopted for its carrying capacity evaluation and analysis
which largely ignored the spatial heterogeneities or non-stationarities in the data relationships.
Methods
2
In this paper
we proposed a technical framework to evaluate and analyze the urban land carrying capacity with geographically weighted (GW) techniques from local perspective. We exemplified this framework with a case study in Wuhan City. In details
we adopted GW summary statistics
GW principal component analysis and GW regression to conduct the evaluation and analysis.
Results
2
The comprehensive pressure of land carrying capacity shows a decaying trend from the city center to the outside areas
to which population density and floor area ratio contribute the most. Moreover
different factors present spatially varying influences on the comprehensive pressure of land carrying capacity.
Conclusions
2
The proposed framework with GW techniques works well on evaluating and analyzing urban land carrying capacity from local perspective
and its evolution is still ongoing with more local techniques involved
which makes it be applicable in more cases and scenarios.
