Research on Temporal and Spatial Distribution of PM₁₀ in Yantai Urban Areas from 2006 to 2010

Abstract:

The purpose of this thesis is to study the characteristics of PM10 concentrations in the atmosphere over time granularity and spatial distribution in Yantai city. The concentration of PM10 is investigated in the daily from 2006 to 2010. The result shows that the characteristics of PM10 concentration in each time granularity are different: the interannual variation can be divided into two stages and the highest is approximately equal twice times of the lowest. The seasonal changes is distinct and the PM10 average concentration presents a feature that spring > winter > autumn > summer. And the highest month of PM10 is April, followed in March and May. The geographical distribution of PM10 is the center of pollution has been located in region A. Each region getting lowest in summer and the minimum one is region H where the concentration is 0.052mg/m3. The function regions can be divided into two categories: most regions show same as the seasonal changes but the region A and G’s characteristics change dramatically and the concentration of PM10 has come to 0.156 mg/m3 in the winter.
