There is growing interest in air quality and air purification, due to current high pollution levels, their effects on human health, and implications for urban economies. Since the improvement of air quality carries important economic value, air-related benefits have been evaluated monetarily from two perspectives: the first relates to air quality improvements, while the second values air purification as an ecosystem function. This research opted for the second perspective, given that the study area (two Colombian municipalities) does not suffer from poor air quality conditions, but stakeholders prioritized this function as highly important to them. Contingent valuation methods were applied in order to identify the population’s probability of willingness to maintain the air purification function. Although individuals (n = 245) attribute a yearly monetary value of USD 1.5 million to air purification, it was found that, despite the high level of social importance that respondents assigned to air purification (mean = 4.7/5), this had no correlation with payment values (rho = 0.0134, p = 0.8350); that is, households do not really recognize the monetary value of all the benefits they receive or the benefits they would lose if the service suffers changes. Hence, it is posed that monetary values do not necessarily reflect the social importance that individuals assign to ecosystem services, and attention is called to the need to integrate social and monetary values into decision-making processes, so as to encompass the complexity of ecosystem services and conciliate conflicting valuation language.

关于哥伦比亚安第斯地区空气净化的货币价值与社会价值之间的不匹配：案例研究

由于当前的高污染水平、它们对人类健康的影响以及对城市经济的影响，人们对空气质量和空气净化的兴趣越来越大。由于空气质量的改善具有重要的经济价值，因此从两个角度对与空气相关的收益进行了货币评估：第一个与空气质量改善有关，第二个将空气净化视为生态系统功能。本研究选择了第二种观点，因为研究区域（两个哥伦比亚城市）的空气质量并不差，但利益相关者认为这一功能对他们非常重要。应用条件评估方法来识别人群愿意维持空气净化功能的概率。虽然个人 ( n= 245) 将每年 150 万美元的货币价值归因于空气净化，研究发现，尽管受访者认为空气净化具有很高的社会重要性（平均值 = 4.7/5），但这与支付价值没有相关性（ ρ = 0.0134, p = 0.8350); 也就是说，住户并没有真正认识到他们获得的所有福利的货币价值或如果服务发生变化他们将失去的福利。因此，提出货币价值不一定反映个人赋予生态系统服务的社会重要性，并呼吁关注将社会价值和货币价值纳入决策过程的必要性，以涵盖生态系统服务的复杂性并调和相互冲突的估值语言。
