Quantitative measurement on urbanization development level in urban Agglomerations: A case of JJJ urban agglomeration

open access: yesEcological Indicators, 2021
The Beijing(Jing)-Tianjin(Jin)-Hebei(Ji) (JJJ) urban agglomeration is one of the three major urban agglomeration in China, which plays an important strategic role in China’s regional development pattern. Based on the concern of inter-relationship within urban agglomeration, this paper creatively proposed a comprehensive gravity-Gram Schmidt ...
