摘　　要：以重庆市渝中区12个城市公园为例,通过自然语言处理、皮尔逊相关系数、IPA分析等方法提取影响使用者正、负情感倾向的公园质量要素。研究结果表明,公园质量要素中景观和环境要素最易被感知,游憩服务设施是影响公园正面感知的关键因素,植被覆盖率与情感倾向呈负相关,公园植被覆盖率过度会引发使用者的消极情绪。基于IPA的感官感知特征分析表明,视觉体验是公园感知中最重要的感官要素,由蚊虫叮咬产生的不适是消极感知的主要来源。Taking 12 city parks in Yuzhong District,Chongqing as an example,the park quality factors affecting users′positive and negative emotional tendencies were extracted by natural language processing,Pearson correlation coefficient,IPA analysis and other methods.The results showed that the landscape and environmental elements were the most easily perceived among the quality elements of the park,and the recreational service facilities was the key factor affecting the positive perception of the park.Vegetation cover was negatively correlated with emotional tendencies,and excessive vegetation cover in parks could trigger negative emotions among users.The analysis of sensory perception characteristics based on IPA showed that visual experience was the most important sensory element in park perception,and discomfort caused by mosquito bites was the main source of negative perception.
