摘要: Clarifying the development relationship between urban built-up land and economic hinterland can provide decision support for regional sustainable development. Using improved field model, geographic concentration elasticity coefficient, taking lower reaches of Yellow River as study area, this defines scope in China from 2005 to 2017, further analyzes dynamic process agglomeration agglomeration, reveals spatial–temporal coupling relationships expansion The results revealed following: (1) From spatial temporal change pattern each city had basically same trend, showing a low degree coincidence with administrative divisions obvious differences change; (2) showed trend centering on cities Zhengzhou Jinan, spreading periphery, gradually forming high-value contiguous area both cities. distribution patterns are mainly manifested circle structure areas “highest-low-higher” concentrations moving away center; (3) underwent an transformation process. 2011, mode was growth, and, 2011 it began shift extensive intensive model has good trend.
