[Pollution Characteristics of Snowmelt Runoff on Different Underlying Surface in Main Urban Area of Harbin].
摘要
was the least, and the significant levels (Sig.) were 0.342 and 0.631, respectively. The results of multiple comparisons showed that the MeanDiffs (Mean Difference) between two underlying surfaces of different pollutants were different, and the contribution rates of different pollution index were different too. Meanwhile, due to the influence of geographical position, for the same pollutant, there were differences in different sampling points of the same underlying surface, especially in city road and pavement. Pollution characteristics of snowmelt runoff on different underlying surface showed that the snowmelt runoff pollution in the main urban area of Harbin was mainly affected by the traffic flow, human activities, coal fired heating in winter and industrial emissions.
