摘要
以阜新城区10种主要绿化植物为研究对象,测定了其不同季节叶片滞尘量,研究了在封闭式和开敞式两种环境不同高度的叶片滞尘量。结果表明:叶片滞尘量的变异系数受不同季节外界自然因素的干扰变化较大,呈现出春季>秋季>夏季的趋势。同种植物在相同高度叶片滞尘量开敞式环境大于封闭式环境,同种植物在不同高度叶片滞尘量封闭式环境没有明显差异,开敞式环境差异显著且低处叶片的滞尘作用最大。一天内植物叶片滞尘量分别在早上8∶00-10∶00和傍晚16∶00-18∶00相对较大。
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.
