摘　　要：为了探讨生态覆盖膜的优化施工参数,采用二因素实验设计,另设对照组,进行16组不同生态覆盖膜浓度、用量的扬尘抑制研究。施工结束4h、1个月、3个月时,16个处理的PM10和PM2.5排放量均小于对照组。施工结束4h和1个月时,不同生态覆盖膜浓度、用量对PM10和PM2.5排放量均具有极显著影响(P<0.01),随着生态覆盖膜浓度、用量的增加,PM10和PM2.5排放量呈现出减小的趋势。施工结束3个月,由于生态覆盖膜的降解,不同生态覆盖膜浓度对PM10、PM2.5排放量没有显著影响(P>0.05),单位面积用量对PM10、PM2.5排放量具有极显著影响,PM10和PM2.5排放量随着单位面积用量的增加而减小。生态覆盖膜浓度为2%,单位面积用量为20L/m2的处理抑尘效果最好,其施工完成4h、1个月和3个月的PM10和PM2.5排放量分别为:118和18,101和15,99和17μg/(m^3·h)。In order to explore the optimal construction parameters of the ecological cover film,a two-factor experimental design was adopted,and a control group was set up to conduct 16 dust suppression studies on the concentration and dosage of different ecological film.The discharge of PM 10 and PM 2.5 in all 16 treatments at 4 h,1 month and 3 months after construction was smaller than that of the control group.At 4 h and 1 month after the end of construction,the concentration and dosage of different ecological film had a significant effect on PM 10 and PM 2.5 emissions(P<0.01).With the increase of the concentration and dosage of ecological film,PM 10 and PM 2.5 emissions showed a decreasing trend.Three months after the completion of the construction,due to the degradation of the ecological cover film,different ecological cover film concentrations had no significant effect on PM 10 and PM 2.5 emissions(P>0.05),and the unit area consumption had a significant effect on PM 10 and PM 2.5 emissions,PM 10 and PM 2.5 emissions decreased as the amount of unit area increases.When the ecological covering film concentration is 2%,and the unit area dosage is 20 L/m 2,the dust suppression effect is the best.Its construction is completed in 4 hours,and the PM 10 and PM 2.5 emissions in 4 hours,1 month,and 3 months are 118 and 18,101 and 15,99 and 17μg/(m 3·h),respectively.
