An ENVI-met Simulation Study on the Influence of Urban Vegetation Congestion on Pollution Dispersion abstract
The goal of the present study is to assess the impact of the vegetation accumulation on the air pollution dispersion. The influence of vegetation on two scales of parks that are in the same distance from the pollution source is the main factor in this paper. The method of this paper is simulating with Envi-met (version 3). two parks with various scales (local and urban scale) and equal vegetation accumulation were simulated in 3 cases (status qua or 12%, 37% and 62% vegetation density). The results revealed that vegetation congestion impact on CO concentration is more impressive for urban scale compared to local scale and the decrease of CO concentration in urban scale is going under a regular process, otherwise, the relationship between vegetation congestion and CO concentration will convert in 62% vegetation congestion. The conclusion of this paper is that vegetation may sometimes intensify air pollution under certain circumstances.
