四川秦巴山区城镇等级规模研究——基于城镇化的多维度响应视角

An Urban Grade Size Study of Qinba Mountain Areas in Sichuan Province Under the Background of Urbanization Multidimensional Response

目前,我国城镇化发展处于机遇与挑战并存的关键时期,四川秦巴山区是国家和省级重点连片扶贫开发区,成为关中平原城市群与成都平原城市群发展的洼地,制约了西部地区的整体发展水平。因此,在"一带一路"战略和"秦巴山区绿色循环发展"战略的推进下,加强四川秦巴山区城镇化建设具有重要意义。以四川秦巴山区为研究区域,以集聚—碎化指数、重力模型理论为依据,结合经济、人口、社会、地理空间等4方面指标从多维度的角度来研究四川秦巴山区现状城镇等级规模、城镇聚集程度和城镇空间关系,并通过变异系数、城镇中心性和城镇发展实力分析,探索城镇等级规模变化趋势,以期为四川秦巴山区的城镇等级规模结构优化和发展提出一定依据与建议。

Recently, urbanization development is in a critical stage with many opportunities as well as challenges in China. Qinba Mountain Areas is the provincial and national level poverty alleviation and development zone. It is the development depression in the urban agglomerations of Guanzhong plain and Chengdu plain, which regulates the development level of the western China. Therefore, it is a significance to accelerate urbanization of Qinba Mountain Areas under the push of ＂One Belt And One Road Initiatives＂ and ＂Green Cyclical Development＂. This paper mainly studied the urban grade size,town agglomeration degree and town space relations of Qinba Mountain Areas based on gather-fragment index and the gravity model theory and combining with the economy, population, society and geography space to provide some structure optimizing and developing foundations and suggestions of Qinba Mountain Areas by analyzing coefficient of variation,Urban centricity and Urban development strength.
