摘要
借助改进熵值法、Jenks自然断裂法、障碍度模型对2007—2020年成渝地区双城经济圈县域尺度城乡融合水平时空分异特征及影响因素进行探讨。结果表明:(1)成渝地区城乡融合发展水平持续提升,城乡融合指数由2007年的0.239提高到2020年的0.534,低、较低水平融合区由2007年的25个减少到2020年的8个,较高、高水平融合区由2个增加到12个。(2)不同维度的融合发展不同步,2020年社会融合发展水平指数最高,为0.612。(3)较高水平融合区在成渝地区的西部和东南部形成两个小范围集聚区,呈现“双核独大、中部塌陷”的发展格局。(4)成渝地区城乡融合发展影响因素中,前期自然要素障碍度高于人口、土地和资金要素,后期自然要素障碍度降低,产业结构和资金要素的障碍度增大。
This paper explored the spatio-temporal differentiation characteristics and influencing factors of urban-rural integration level at the county level in the Chengdu-Chongqing Economic Circle from 2007 to 2020 by using improved entropy method,Jenks natural fracture method,and obstacle model.The results show that:(1)The level of urban-rural integration development in the Chengdu-Chongqing region continues to improve,with the urban-rural integration index increasing from 0.239 in 2007 to 0.534 in 2020,the number of low and lower level integration areas decreasing from 25 in 2007 to 8 in 2020,and the number of high and higher level integration areas increasing from 2 to 12.(2)The development of different integration dimensions is not synchronized,and the highest index of social integration development level is 0.612 in 2020.(3)The high-level integration zone forms two small-scale agglomeration areas in the western and southeastern parts of the Chengdu-Chongqing region,presenting a development pattern of“dual core dominance”but“central collapse”.(4)The obstacles degree to urban-rural integration development in the Chengdu-Chongqing Economic Circle are relatively higher in the early stage due to natural factors than population,land,and financial factors.In the later stage,the obstacles degree of natural factors decrease,while the obstacles degree of industrial structure and financial factors are more significant.
