人们对城市森林的体验越来越感兴趣，因为相关研究表明，森林环境可以促进心理健康。对森林体验的心理反应可以通过面部表情来评估，但相关知识在大的地理范围内是有限的。在这项研究中，从2018年10月1日至7日在中国12个随机选择的城市的新浪微博（一种类似于中国Twitter的社交媒体应用程序）上收集了2824张照片的数据集，详细说明了城市森林游客的评估年龄（幼儿、青年、中年和老年人）和性别。采用FireFACE V1.0软件对快乐和悲伤表情进行评分，用快乐得分减去悲伤得分计算出积极反应指数（PRI）。收集区域环境因子，采用回归分析方法检测驱动因素。在森林中，快乐的得分比在城市环境中要高，而在森林中，幼儿的悲伤得分比在散步和广场中要低。女性比男性表现出更多的积极情绪表达。快乐指数的上升是由日最低气温的上升所驱动的；而PRI则随着纬度的增加而下降。总的来说，城市森林的体验可以唤起积极的情绪，这可能是由于温暖的温度下的舒适感觉。
There is increasing interest in experiences of urban forests because relevant studies have revealed that forest settings can promote mental well-being. The mental response to a forest experience can be evaluated by facial expressions, but relevant knowledge is limited at large geographical scales. In this study, a dataset of 2824 photos, detailing the evaluated age (toddler, youth, middle-age, and senior citizen) and gender of urban forest visitors, was collected from Sina Weibo (a social media application similar to Twitter in China) between 1–7 October 2018, in 12 randomly chosen cities in China. Happy and sad expressions were rated as scores by FireFACE software V1.0, and the positive response index (PRI) was calculated by subtracting sad scores from happy scores. Regional environmental factors were collected to detect driving forces using regression analyses. Happy scores were higher in forests than in urban settings, while sad scores for toddlers were lower in forests than in promenades and squares. Females showed more positive emotional expressions than males. Increases in happy scores were driven by the increase of daily minimum temperature; while PRI declined with increases in latitude. Overall, an urban forest experience can evoke positive emotions, which is likely due to comfortable feelings in warm temperatures.
