基于大学生认知地图的长江中游城市群空间范围认知

国务院《长江中游城市群规划》的颁布虽然结束了一直以来的“中三角”和“中四角”的争论,但与公众对其空间范围的认知仍然存在一定的差异。通过问卷获取武汉、长沙和南昌三市大学生对长江中游城市群空间范围的认知地图,并绘制认知范围集成图、密度图和认知比例图等分析其认知特性;通过构建面积偏差系数和中心偏差系数度量了认知地图与规划地图的差异,探究个体社会属性对认知差异的影响。研究发现：① 三市大学生的认知地图呈“武汉+”的特色,长沙市有“南向偏移”的趋势、南昌市“东南向偏移”趋势明显;② 三市大学生的空间认知范围与《长江中游城市群规划》的范围存在差异,其中南昌市大学生差异最大,长沙次之,武汉最小;③ 个体社会属性与认知差异存在关联,其中性别、居住地、专业和居住时间变量为显著影响因子。公众空间认知的差异及其影响因素在一定程度上会影响到城市群发展的政策偏好,研究结论可为未来城市群的构建和城市政策的制定提供新的参考。

Spatial scope cognition of urban agglomeration in the middle reaches of the Yangtze River from the perspective of college students

The promulgation of Development Plan of Urban Agglomeration in the Middle Reaches of the Yangtze River (2015-2030) by the State Council of the People's Republic of China delimited the scope of Urban Agglomeration in the Middle Reaches of the Yangtze River (UAMRYR) and put an end to the dispute of "triangle" or "quadrilateral" (i.e. , whether Anhui province is included in UAMRYR or not). However, as the UAMRYR is an administrative scope, some distortions still exist in contrast to the scope cognized by the public. The advancement of information technologies strengthens the weight of public in the interests game, and reshapes the diversified pattern of "government + market + public" in public policies. To a certain extent, public cognition and its determining factors have exerted substantial impact on the policy orientation of the development of UAMRYR. Nevertheless, the public are overlooked in the existing studies on the delimitation of urban agglomeration. Hence, it is necessary to illustrate the scope delimitation of UAMRYR from the public perspective. Taking into account college students' diversified individual attributes, comprehensive knowledge, and the "main labor force" role in the forthcoming years, they are selected as the representative of the public. Survey questionnaires are conducted on the junior and senior college students in Wuhan, Changsha and Nanchang to acquire their cognitive maps of UAMRYR and individual socio-economic information. Area distortion index and center distortion index are introduced to quantitatively measure the scope distortions between the cognitive maps and the Plan map. Furthermore, a binary logistic regression model is applied to explore how individual socio-economic attributes impose influence on the cognition distortions. The research findings reveal that: (1) Cognitive maps of UAMRYR drawn by college students in the three cities are generally characterized by "Wuhan +" (i.e., Wuhan-centered), and that of Changsha and Nanchang has a distinct distortion tendency towards south and southeast respectively; (2) In contrast to the Plan map, the cognitive maps in the three cities have various degrees of distortion, among which Nanchang holds the largest distortion degree, followed by Changsha and Wuhan; (3) Individual socio-economic attributes generate different impacts on the cognition distortions. Gender, residence place, major and residence time are the significant determining factors in the study.
