- 摘要：
采用年度社会经济数据和SPSS软件的降维分析方法，改进引力模型中的“城市质量指数”与“时空间距离”。应用该模型，对“高铁时代”来临前后的武汉城市圈内部空间经济联系强度进行度量和对比，并使用GIS对域内各城市间经济联系的空间分布特征进行可视化分析。最后，引入交通流量位置大数据对模型结果进行验证。对“高铁时代”来临前后的区域联系及协调发展状况进行科学评估，并基于此对城市圈发展规划提供可行政策建议。 - 关键词：

The new model is applied to measure and compare the spatial economic links within Wuhan city circle before and after the advent of¡°high-speed rail era¡±, and to visually analyze the spatial distribution characteristics of economic links among cities in the region by using GIS. Furthermore, location-based big data has been introduced to verify the model results. Finally, the big data of traffi c fl ow location is introduced to verify the model results. It scientifi cally evaluates the status of regional connections and coordinated development before and after the ¡°high-speed rail era¡±, and provides feasible policy recommendations for the development plan of the city circle based on this.
