欠发达民族地区县域新型城镇化时空测度与评价——以青海东部重点开发区为例

Spatio-temporal assessments of urbanization level in underdeveloped Multi-ethnic regions:A case study on qinghai eastern key development zone

[目的]为推动欠发达民族地区县域新型城镇化建设,[方法]采用改进后的熵值法构建青海东部重点开发区县域新型城镇化复合指标评价体系,用地理空间分析方法和GeoDA对研究区进行县域新型城镇化水平时空测度及评价。[结果](1)在2004-2014年间,青海东部重点开发区的综合城镇化、人口城镇化、社会城镇化、基础设施城镇化均呈上升趋势,生态环境城镇化指数呈下降趋势,2009-2014年县域城镇化发展速度高于2004-2009年;(2)城镇化水平空间差异显著:Moran’s I由2004年的0.525 2上升至2014年的0.595 1,说明新型城镇化水平在空间上呈现明显的集聚现象,并且集聚有进一步的增强趋势,LISA局域自相关显示城镇化水平县域差距大,城镇化水平断层明显。[结论]该区域城镇化水平高的县域应发挥辐射扩散作用,加强同邻近周边县级城镇的交流和联系,促进县域城镇化的协同推进。

[Objective]Present study was conducted to promote new urbanization in underdeveloped multi-ethnic region.[Methods]A new evaluation system with composite index for urbanization level determination was produced with an improved entropy method.The urbanization level of the study area was measured and evaluated spatially and temporally with the methods of geographical spatial analysis and GeoDA.[Results]Study results showed that：（1）The comprehensive urbanization,population urbanization,social urbanization,and infrastructure urbanization for the key development zones in the east of Qinghai were all leveled up during 2004-2014,and the development speed of the county urbanization during 2009-2014 was higher than that during 2004-2009,while the urbanization index of ecological environment was decreased.（2）The spatial difference of urbanization level was significant：Moran＇s I was improved from 0.525 2 in 2004 to 0.595 1 in 2014,which indicated that the obvious agglomeration phenomenon was produced for the new type of urbanization level in space,and then this agglomeration was further strengthened.Moreover,the LISA LAN autocorrelation demonstrated that the county urbanization level gap was big,and the urbanization level fault was obvious.[Conclusion]The county area with high urbanization level should play the role of radiation diffusion and strengthen the communication and connection with neighboring counties and towns,and promote the joint development of county urbanization.
