Detaining dust law of landscape greening plants leaves in urban area of Fuxin
In this study, ten main greening plants in urban area at Fuxin are selected for determining the amount of detaining dust on their leaves in different seasons, and also the amount of detaining dust on their leaves at different heights in a close environment and an open environment. Variation coefficient of the amount of detaining dust on their leaves changes greatly because of the interference of external natural factors, which presents an order relationship of dust detention: spring > autumn > summer. The amount of detaining dust on leaves of the same plant with the same height in an open environment is higher than that in a close environment. The amount of detaining dust on leaves of the same plant with the different height in a close environment shows no significant difference, and the one in an open environment shows significant difference, which indicates that detaining dust effect of low height leaves are better. The dust detention amount of plant leaves is relatively more at 8:00-10:00am in the morning and 16:00-18:00pm in the afternoon respectively than that at other periods.
