基于空间自相关的江苏省城镇化水平空间格局研究

Spatial Pattern of Urbanization Level Based on Spatial Autocorrelation in Jiangsu Province

从人口、经济、社会生活三个方面,选取12项指标构建了江苏省县域城镇化水平的评价指标体系,采用主成分分析法提取主因子并计算各县域城镇化水平的综合得分,以综合得分为变量进行空间自相关分析.结果表明,江苏省县域城镇化水平在整体上呈现出较强的空间自相关性,城镇化水平高的县域和城镇化水平低的县域分别在空间上相邻;同时也反映出江苏省各区域中心城市对其周边县域城镇化的辐射作用还比较弱.

Virtual reality technology is one of the important theory of practice and application, which have a wide range of applications in many fields. 3Dmax was introduced as the modeling and mapping software and unity3d was used as development platform, and the key technologies to construct the virtual indoor wandering system were demonstrated, such as free walking flying, object reset, voice and video control, and finally the concrete solution was put forward. Then unity3d-based technology virtual indoor wandering system scene modeling and its application was presented. An extensible user-interactive platform was put forward. Which platform allowing users design virtual indoor wandering system according to their personal choice.
