Inspired by observations at the Guandu Wetland near the estuary of the Tamsui River in northern Taiwan, this study investigates the relationship between wetland vegetation density and its effectiveness in mitigating air pollution, particularly in relation to the location of nearby buildings. By participating in the GLOBE Program, we compared air quality data from within and outside the school campus with GLOBE data. We also contributed to the program by installing pollution monitoring instruments. Focusing on the blocking effects of wetland vegetation on air pollution, we specifically explored the location and density of dense vegetation. To gather data, we designed wind tunnel experiments to identify the optimal placement of wetland vegetation for improving air quality. Using a self-constructed acrylic wind tunnel, we conducted 40 experiments, considering factors such as pollutant emission times, vegetation location, and vegetation density. The experimental results demonstrated consistency and reproducibility, ensuring the reliability of the findings. The analysis revealed that denser wetland vegetation, placed farther from pollution sources and closer to residential buildings, significantly improved air quality, highlighting the potential of wetlands to enhance urban environmental conditions.
