都市公園綠地建設對粒狀空氣污染物質之改善效果研究

The Effects of Urban Park Development for Improving Particle Air Pollutants

本研究目的在於瞭解台北市與高雄市之公園綠地對粒狀空氣污染物質之改善效果。本研究以空氣品質監測站半徑500m有效範圍為調查範圍，調查區內的公園綠地面積、行道樹、車流量、工業區面積、及粒狀空氣污染物質（落塵、TSP、PM10），採迴歸分析法進行公園綠地對粒狀空氣污染物質之改善效果分析。結果顯示，公園綠地與行道樹有無，對於淨化落塵與TSP的成效最為顯著，即公園綠地面積越多、或設置有行道樹時，則落塵與TSP濃度會越低。因此建議於污染較嚴重之道路或工業區旁，增設公園綠地或行道樹，進而提升都市環境品質。 The purposes of this study were to explore the improvement effect of urban park development for particle air pollutants in Taipei and Kaohsiung cities. The study areas were the 500m effective monitoring radius of air quality monitoring stations in Taipei and Kaohsiung cities. We investigated the areas of urban park and industry park, roadsides trees, traffic flow, and particulate matters quality (Dust-fall, TSP, PM10). Then we used the regression analysis method to analyze the improvement effect of urban parks and roadsides trees for particle air pollutants. The results suggest that there is a significant effect between the urban parks or roadsides trees and Dust-fall and TSP. It shows that the more urban parks or roadsides trees, the less concentration of Dust-fall and TSP. It concludes that the governments should development more urban parks or roadsides trees near the industry areas and the main roads for improving urban environmental quality.
