Abstract:
PM10 in the atmosphere was taken as test object，and the mass concentration of the air PM10 was measured continuously by using the portable hand-held particulate matter concentration monitor Dustmate，diurnal variation and monthly variation of the PM10 concentrations from in different forest margins and road distance were researched.The results showed that diurnal variation of PM10 concentration presented that first decreased and then increased in different forest edge distance.In June,July and October the maximum value appeared at 07:30.In August and September the maximum value appeared at 05:30.In different month，the minimum value appeared at 13:30 or 15:30.The monthly variation showed that first decreased and then increase.With the increase of the distance from the forest edge，30 m away from the forest edge was an important turning point in the change of PM10 concentration.The diurnal variation of PM10 concentration in different road was the same as that of different forest margins，but the time of peak value was different.The minimum value appeared at 13:30 or 15:30.In June,August,September，maximum value appears at 05:30.In July，the maximum value appeared at 07:30.In October，the maximum value appeared at 09:30.Monthly variation showed that the sharp decline in the distance from the road 0-30 m and the trend was slower in away from 30 m.Reduction rate of PM10 concentration was maximum in distance from the road 30 m.With the month increased，reduction rate of PM10 concentration showed first increased and then decreased at a distance of road and forest edge 0-30 m.The results of this study could provide data support for the air pollution in Beijing area.
