Abstract:

With the rapid development of urbanization, the complex system of industry, population and land is increasingly important for regional development. This research is intended to study the coupling coordination and spatio temporal evolution characteristics of industrial deagriculturalization, population urbanization land deagriculturalization in the urbanization development of the Central Plains urban agglomeration, so as to provide reference and basis for the healthy development of the Central Plains urban agglomeration in Zhongyuan city group. Based on the data from 2006 to 2016, the coupling coordination degree model and ArcGis software were used to analyze the spatio temporal characteristics of the industry, population and land deagriculturalization in Zhongyuan city group and its development trend. Results were showed as follows. According to the time series characteristics, the coupling coordination degree between population urbanization, industrial deagriculturalization, and land deagriculturalization was generally decreasing in Zhongyuan city group, stable and rising. The coupling coordination degree of the whole district in 2006, 2011 and 2016 was 0.57, 0.53 and 0.55, respectively. And the overall coordination of them was in a moderate stage. From the perspective of spatial characteristics, the spatial pattern of the coupling and coordination of industry, population and land deagriculturalization in Zhongyuan city group had experienced a distribution pattern of "three points" from the ring to the "T" shape. In summary, the healthy development of urban agglomeration should strengthen the coordinated development of the city, enhance the leading role of demonstration; enhance the ability of independent development, narrow the regional development gap, so optimizing the industrial spatial pattern and promoting the comprehensive development of the city is the enlightenment of the coordinated development of urbanization in the future.
