基于多模态时空数据的大学校园户外公共空间形态与活力的关联机制及优化模式研究 ——以南京为例

大学校园户外公共空间是我国高等教育实现内涵式发展的重要载体，空间优化和活力提升已经成为其在当代所面临的重要问题之一，但是在实际操作中由于许多大学校园户外公共空间存在着数量不足、活力不够以及适应性不强的问题而遇到诸多困难，直接影响到教书育人目标的实现。本研究聚焦大学校园户外公共空间的形态和活力问题展开专题研究，以南京地区为例，通过系统实证调研与量化研究建立大学校园户外公共空间形态与活力信息数据库，揭示形态和活力各自的关键性指标体系以及核心影响因素，基于多模态时空数据，通过人本尺度的人体感知数据实测和分析，建立空间形态—人体感知—空间活力之间的动态模型，研究空间形态与空间活力的关联机制，凝练大学校园户外公共空间优化模式。研究拓展了现有空间形态与活力的研究，有助于提升大学校园公共空间形态和活力研究的精确性、科学性和预见性，研究成果对于我国城市公共空间的精细化设计也具有积极的参考价值。

The campus exterior public space is an important supporter to realize the connotative development of higher education in China. The optimization of space and the promotion of vitality have become one of the important issues that it faces now. However, in practice, many difficulties are encountered due to the shortage of quantity, vigor and adaptability in the campus exterior public space, which directly affects the realization of the goal of teaching and educating students. This study focuses on the morphology and vitality of campus exterior public space. Taking Nanjing area as an example, this paper establishes the information database of exterior public space morphology and vitality through systematic empirical research and quantitative research. Based on multi-modal spatio-temporal data analysis, the dynamic model of spatial form-human perception-space vitality is established, and the correlation mechanism between spatial form and spatial activity is studied. The research has expanded the existing space form and vitality research, helps to enhance the campus exterior public space form and vitality research precision and the scientific nature, also has the positive reference value for our country city public space optimization design.
