Air pollution in the mountains occurs from time to time. Because of its serious harm, it has attracted widespread and high attention from the whole society. In this regard, many fruitful researches have been carried out at home and abroad and have been widely used. In the development of the analysis theory of the causes of traffic accidents, the theory of system causes is a relatively comprehensive theory, which systematically analyzes the causes of traffic accidents from many aspects in order to find its internal connections. The rise and development of data mining provide powerful tools for the practical application of this theory. There are many small cities and they are facing serious air pollution problems, but there are few studies on the characteristics of air pollution in mountainous urban and rural areas and their influencing factors. Taking the deep mountain area as an example, this paper analyzes the temporal and spatial characteristics of air environmental quality in mountainous urban and rural areas with SO₂, PM10, PM2.5, NO₂, CO, and O₃ as the main analysis indicators, and compares them with plain cities at the same latitude and studies the characteristics of urban and rural air pollution in mountainous areas and its relationship with terrain and meteorological conditions. Based on the analysis results of the temporal and spatial variation characteristics of air pollution factors, topography and meteorological effects on air pollution and human activities, the characteristics of air pollution in mountainous areas are summarized, and prevention and control measures adapted to local conditions are proposed. Finally, as an important form of artistic expression in urban public spaces, urban public art plays an important role in improving the level of urban cultural construction. At present, the public’s demand for participating in urban public art is becoming stronger and stronger. Taking technological development as the starting point, this article explores the innovative path of urban public art design based on interactive experience.

山区空气污染时有发生。由于其危害严重，引起了全社会的广泛和高度关注。对此，国内外进行了许多卓有成效的研究，并得到了广泛的应用。在交通事故原因分析理论的发展过程中，系统原因理论是一个相对综合的理论，它从多方面系统地分析交通事故的原因，以寻找其内在联系。数据挖掘的兴起和发展为这一理论的实际应用提供了有力的工具。小城市众多，面临严重的空气污染问题，但对山区城乡空气污染特征及其影响因素的研究较少。₂、PM10、PM2.5、NO ₂、CO和O ₃为主要分析指标，与同纬度平原城市进行比较，研究山区城乡空气污染特征及其与地形、气象条件的关系。根据大气污染因子时空变化特征、地形气象对大气污染和人类活动影响的分析结果，总结山区大气污染特征，提出因地制宜的防控措施。 . 最后，作为城市公共空间重要的艺术表现形式，城市公共艺术对于提升城市文化建设水平具有重要作用。当前，公众参与城市公共艺术的需求越来越强烈。
