摘要缺乏空间精度高、便于获取的教学实例数据,是城市空间结构教学质量难以提高的关键瓶颈问题。为提高教学质量,本文对基于POI大数据的城市空间结构教学改革进行了探讨。首先,阐述了POI大数据的基本特点,及其在可视化、精细化和定量化分析中的突出优势;并以郑州市中心城区为案例,介绍了基于POI大数据的教学改革实践。实践表明,将POI大数据引入城市空间结构的教学,可以有效地提升教学质量。

AbstractThe lack of teaching case data, which has high spatial accuracy and can be easily to obtain, is the key bottleneck of improving the teaching quality of urban spatial structure. To improve the teaching quality, we discussed the teaching reform of urban spatial structure based on POI big data.This paper firstly described the basic characteristics of POI big data and its outstanding advantages in visualization, refinement and quantitative analysis. Then, taking the downtown area of Zhengzhou as a case, this paper introduced the teaching reform practice of POI big data. Practice showed that the introduction of POI big data into urban spatial structure teaching can effectively improve the teaching quality.

城市空間结构是城乡规划专业的“城市地理学”课程的核心内容,主要讲授城市的形态和功能在空间布局上的结构特征,这是教学中的重点内容、也是教学难点。从课堂测验和期末考试的成绩,以及规划设计院等用人单位的反馈来看,城市空间结构部分是“城市地理学”课程中教学质量较差的主要环节。为探究教学质量较差的症结所在,笔者梳理了多年来的教学经验,并与相关院校的课程主讲教师进行了深入的沟通和研讨。我们发现,城市空间教学质量难以提高的重要瓶颈问题是缺乏丰富的教学实例数据。教学实例的缺乏使得学生对城市结构的感性认知较为匮乏,难以在有限的感性认知的基础上建立系统的理性认识。究其原因,首先是由于常规统计资料的统计单元尺度较大,往往只公布城市的总量数据;在更为精细的城市尺度上,很难收集到统计数据。……
