| [Purpose] Since the 21 st century,in order to narrow the gap between urban and rural areas,a series of macro-measures have been introduced one after another.In this context,to promote the coordinated development between regions and urban and rural areas and the integration of urban and rural development is an important subject for geographical research to meet the national strategic needs.As one of the 19 major city agglomerations in our country,the Yunnan city agglomerations,coupled with its location in southwest region,have unique and complex characteristics in the integrated development of urban and rural areas.In addition,as the core region of Yunnan province,the development of urban-rural relations is representative to a certain extent,and has important reference significance for the development of urban-rural relations in other areas of Yunnan province.This study focuses on the spatio-temporal evolution process and characteristics of the urban-rural integration development level of central Yunnan urban agglomeration in the past 15 years,and analyzes its driving force,which is conducive to improving the urban-rural integration development level of central Yunnan urban agglomeration and other areas of Yunnan Province,providing certain scientific theoretical basis for realizing the balanced and coordinated development of urban and rural areas,and providing certain reference value for the decision-making of the government.[Research Methods] In this study,GIS spatial analysis and spatial econometric model are comprehensively used to measure the urban-rural integration development level of central Yunnan urban agglomeration,and analyze the driving mechanism affecting the urban-rural integration development level.In terms of mathematical model,multiple Logistic regression analysis is used to establish the spatial characteristic index model of urban-rural integration development level of central Yunnan urban agglomeration,so as to quantitatively measure the urban-rural integration development level of central Yunnan urban agglomeration.Secondly,exploratory spatial data analysis is used to explore the evolution characteristics of spatial pattern of urban-rural integration in central Yunnan urban agglomeration in the past 15 years.On this basis,the driving force of urban-rural integration development of central Yunnan urban agglomeration is analyzed,and the existing problems in the process of urban-rural development of central Yunnan urban agglomeration are obtained,and the optimization strategy to improve the urban-rural development level of central Yunnan urban agglomeration is proposed.[Results](1)In the past 15 years,the urban-rural social and economic integrated development level of central Yunnan urban agglomeration has been continuously enhanced,and the social and economic integration drives the spatial integrated development,which continuously optimizes the overall urban-rural integrated development level structure.In 2005,2010 and 2015,it was social and economic integration > population integration > ecological integration > spatial integration.By 2020,the level of spatial integration will be improved,and the level of integration of all dimensions will change into socio-economic integration > spatial integration > population integration > ecological integration.(2)From the spatial and temporal distribution pattern and evolution characteristics of the urban-rural integration development level of the central Yunnan urban agglomeration,the high value area of the urban-rural integration development level of the central Yunnan urban agglomeration moves from the eastern region to the central region,while the low value area is mainly distributed in the western region,showing the characteristics of first expansion and then contraction;According to the spatial autocorrelation analysis,the spatial aggregation characteristics of the urban-rural integration development level distribution in central Yunnan urban agglomeration are significant.From the county scale,the urban-rural integration development level presents a positive correlation with the surrounding areas.There are high concentration areas and low concentration areas,and the high concentration areas are mainly distributed in the central Kunming city and the eastern Qujing city of the central Yunnan urban agglomeration.Low and low concentration areas are mainly distributed in counties under the jurisdiction of Chuxiong Prefecture in the west.(3)From the perspective of driving force of urban-rural integration development,it is mainly affected by four driving factors: social and economic development is the core driving force,factor flow and allocation is the basic driving force,government policy and management is the external driving force,and ecological environment carrying capacity is the continuous driving force. |
