| 摘 要： | 采用地理国情监测数据和统计数据,研究识别城镇的社会经济影响区范围,对成渝城市群在四川的113个县域,从城镇综合实力、可达性、影响力及城镇影响区特征进行分析。研究结果表明,形成了以覆盖成都、德阳、绵阳、眉山与资阳为核心的强影响力空间连片区,与其他县域城镇综合实力的极化现象较为突出。主要存在影响区扩展的城镇,扩展的影响区域已明显覆盖了相邻县城的影响区,较好地呈现出这部分县域经济正趋于融合,形成多极点的县域经济协同发展模式。

| Abstract: | This study used geographic conditions monitoring data and statistical data,conducted an in-depth analysis of synthetic strength,accessibility,and influence strength and effect regions of 113 counties aloge with Chengdu-Chongqing urban agglomeration in Sichuan.The result showed that region has formed a strong influence space link area covering Chengdu,Deyang,Mianyang,Meishan and Ziyang,which showed prominent polarization on synthetic strength.The expansion and contraction of counties' effect regions were influenced by the synthetic strength,accessibility and geographic conditions.There were expansion counties in study area.These counties' effect regions obviously covered their adjacent ones. |
