小型公共绿地支持在地交往活动的情感 增效途径研究

小型公共绿地能支持在地交往活动，继而强化积极情感，在绿地日常使用机会减少的现实背景下，有必要提升活动者在有限活动机会中获得积极情感的能力。总结了调控活动的发起形式、强化活动的社会联系性、提升活动的空间可供性3条情感增效途径，比较了3条途径的情感增效能力，提炼了促成高、低情感增效结果的正、负空间组态，分析了组态单元中的活动特征。研究发现：在增效途径上，提升空间可供性相较于其他2条途径能更好地促成情感增效；在空间组态上，fsQCA适合提炼面向情感增效的空间组态，由此提炼得到4类正向促进组态与3类负向抑制组态；在活动特征上，正向促进组态单元活动彼此协调，公共型、低强度活动情感增效潜力被激发；负向抑制组态单元活动彼此干扰，亲密型、高强度活动情感增效能力被削弱。研究成果能为健康效率导向下的小型公共绿地建设与更新提供参考。

Research on Approaches for Synergy between Decreasing Visit Costs and Increasing Emotion Benefits from the Perspective of Small Public Green Spaces Supporting Local Interaction Behaviors

Small public green spaces increase positive emotions by supporting local interaction behaviors. In the context of the reduction of residents'' daily visits to public green spaces, it is necessary to increase residents'' emotion benefits with decreasing visit costs. This research summarizes 3 approaches for synergy between decreasing visit costs and increasing emotion benefits, which include regulating behavioral forms, strengthening social connections and improving spatial availability; compares the synergy level of these 3 approaches; concludes positive and negative spatial configurations which lead to high and low synergy results correspondingly; analyzes behavioral characteristics in positive and negative spatial configuration units of small public green spaces. Results show that: improving spatial availability can better promote the synergy level than the other 2 approaches; fsQCA is applicable to concluding spatial configurations for synergy, with which 4 positive and 3 negative spatial configurations are concluded; behaviors coordinate well and the potential for synergy of public and low-intensity behaviors is stimulated in positive configuration units, while behaviors interfere with each other and the ability for synergy of intimate and high-intensity behaviors is weakened in negative configuration units. The results shown above can provide references for construction and renewal of small public green spaces under the guidance of human health efficiency.
