Global climate change and the deteriorating quality of urban air are the major issues affecting the atmospheric ecosystem of Pakistan. To avoid poor monitoring and management of air pollution, improvements through the latest technologies such as GIS and remote sensing are required. This research involves spatial analysis, which discusses the impact of vegetation on air quality and public health. Data of air quality at 20 different points, showing the concentration of four pollutants, namely NOx, CO, SO, and PM, with mean observations for 24-h, are taken from EPA, Lahore. The results show that the concentrations of SO2, CO, and PM are exceptionally high at the site of the Badshahi Mosque. The analysis shows that the highest polluted areas have the lowest vegetation levels, whereas areas with low pollution concentration have more vegetation cover. Moreover, less vegetation has a higher death rate attributable to household air pollution. The study suggests that greening strategies, vegetation screens, and vegetation barriers should mitigate urban heat air pollution and minimize the air pollution attributable deaths. For pollution and vegetation monitoring, strict laws and monitoring programs must be implemented in major cities.
全球气候变化和城市空气质量恶化是影响巴基斯坦大气生态系统的主要问题。为了避免对空气污染的监测和管理不善，需要通过 GIS 和遥感等最新技术进行改进。本研究涉及空间分析，讨论了植被对空气质量和公众健康的影响。空气质量数据来自 EPA，拉合尔，共有 20 个不同地点，显示了四种污染物（NOx、CO、SO 和 PM）的浓度，平均值为 24 小时。结果表明，巴德夏希清真寺所在地的 SO2、CO 和 PM 浓度异常高。分析表明，污染最严重的地区植被水平最低，而污染浓度较低的地区植被覆盖更多。此外，较少的植被导致更高的归因于家庭空气污染的死亡率。该研究表明，绿化策略、植被屏蔽和植被屏障应该可以减轻城市热空气污染，并最大限度地减少归因于空气污染的死亡人数。为了进行污染和植被监测，必须在主要城市实施严格的法律和监测计划。
