中国中西部地区就近城镇化空间演变及类型分异

就近城镇化是中西部地区协同推进新型城镇化和乡村振兴战略要求的现实路径选择。通过构建就近城镇化空间演变类型划分方法，从整体区域和城市群两个尺度，分析2000—2015年中西部地区就近城镇化的空间类型分异特征。研究发现：(1)整体区域尺度，中西部地区就近城镇化水平持续上升，东西差异不断加大、南北差异不断减小，本县优势型空间单元占主体；且可划分为17种空间演变类型，其中，中水平正增长本县优势型、低水平正增长本县优势型、高水平正增长本县优势型和低水平正增长本镇优势型是主导类型；(2)城市群尺度，中西部城市群地区的就近城镇化发展水平和增长速度远高于非城市群地区，且呈现明显的群际分异和群内分异，且城市群地区的就近城镇化空间演变类型可划分为多峰—多重尺度、多峰—中长尺度、多峰—中小尺度、单峰—中长尺度、单峰—小尺度等5种模式。

SPATIAL EVOLUTION AND VARIATION TAPES OF NEARBY URBANIZATION IN CENTRAL AND WESTRN CHINA

Nearby urbanization is a realistic path choice for the central and western regions to promote newtype urbanization and rural revitalization strategy. By constructing the classification method of spatial evolution types of nearby urbanization, this paper divides the spatial types of nearby urbanization in the central and western regions in 2000-2015. On this basis, from the scale of the whole central and western regions to the scale of the urban agglomerations, this paper systematically analyzes the spatial variation types of nearby urbanization in central and western regions. The study finds that: 1) From the scale of the whole regions, the level of urbanization in the central and western regions continues to rise, the diversity between the east and the west continues to increase, and the difference between the north and the south continues to decrease, and the advantageous spatial units of the county occupies the main part. 2) From the scale of the urban agglomerations, the development level and growth rate of nearby urbanization in the central and western urban agglomeration areas are much higher than those in non-urban agglomeration areas, and they show obvious inter-group differentiation and intra-group differentiation.
