摘要：

综合运用加权平均旅行时间模型、修正后的引力模型、主成分分析、地统计分析、空间探索性分析、多元线性回归分析等技术模型和方法,对山西省107个研究单元的可达性及城市经济联系格局进行分析。结果表明：①整体来看,山西省可达性水平形成以太原盆地城镇密集区为核心,向外围逐渐递减的核心—边缘分布格局;局部来看,东部可达性优于西部,南部优于北部。②县际经济联系空间结构呈“大”字形,初步形成“一核一圈三群”的空间联系格局;城市对外联系总量差异较大,空间上表现为以省会和个别综合实力较强的单元为主的中心—外围格局,西部沿黄河一带的边缘单元与全省其他单元联系微弱,对外联系强度小;各省辖市与北京、石家庄、西安、济南、郑州联系紧密,与银川、兰州等西部省会城市联系较弱。③县际经济联系受城市基础规模、交通优势度、区位、城市化水平、地形等因素影响。

Abstract:

Using weighted mean travel time model, gravity model, principal component analysis, geostatistical analyst, exploratory spatial data analysis, and correlation and regression analysis methods and techniques, this study conducted an in-depth analysis of accessibility and urban spatial connections of 107 county-level administrative units in Shanxi Province. The results are as follows. First, accessibility of cities in Shanxi Province is highest in the highly urbanized area of the Taiyuan Basin and gradually decreases outward, which presents a core-periphery distribution pattern. Locally, accessibility in the eastern part is better than the west, and the south is better than the north. Second, economic connections at the county scale form an one core, one circle, and three groups spatial pattern; the overall linkages of cities differ and show a provincial capital and cities with higher overall strength centric distribution pattern. Peripheral county-level units along the Yellow River in the west present weak connections with other units and the overall linkages are small too. Cities in Shanxi Province have close connections with Beijing, Shijiazhuang, Xi'an, Ji'nan, and Zhengzhou and have weak connections with Yinchuan, Lanzhou, and other western provincial capital cities. Third, economic strength, transportation condition, location, urbanization level, and relief of land surface are the main influencing factors of economic connections at the county scale in Shanxi Province.

Key words: accessibility, economic linkage at county scale, spatial pattern, influencing factor, Shanxi Province
