广州大学城环境因素对学生安全感的影响研究

深入理解环境特征与心理感知的关联对提升城市空间品质具有重要意义。通过在广州大学城内随机抽取300 张 街景照片进行打分，研究安全感评价的空间分布，及多种环境因素对学生安全感的影响。结果表明学生安全感评价在 不同土地利用类型中分布不均，高校用地的评价最高，公园绿地次之，城中村的评价最低；“他人的存在”对安全感 无显著影响，高管理水平的环境在高校校园、城中村、公园绿地三类用地中都能显著提升学生的安全感；高校校园和 公园绿地中，可视性强的环境对安全感的提升有显著的积极作用；校园环境美观程度越高、绿视率越低，学生的安全 感评价更高。并计算环境因子指标权重，建立初步的大学城校园环境安全感评分体系。

The Impact of Environmental Factors on the Perceived Safety of Students in the Guangzhou Higher Education Mega Center

Developing a deeper understanding of the relationship between environmental characteristics and the perceptions of individuals is of great significance for improving urban spatial quality. In the present study, the spatial distribution of perceived safety and the relationship between perceived safety and multiple environmental factors were investigated by scoring 300 random streetscape photos of the study area. Results showed that the perceived safety of students is unevenly distributed among different land-use types, with the highest safety perceptions being observed at the college campus, followed by the green space. On the contrary, the urban village had the lowest safety perception. 'The existence of others' had no significant impact on perceived safety, and environments with high levels of management were found to have significantly increased safety perceptions in the three land-use types, including college campuses, urban villages and green space. In college campuses and green space, visibility was found to have a significantly positive effect on perceived safety, while the campus environment with a high aesthetic level and low visible green index indicated higher perceived safety. Moreover, the weights of different environmental indicators were calculated, and a preliminary scoring system of environmental perceived security in university towns was established.
