摘    要:利用1990~2002年呼和浩特市区空气污染物TSP、SO2、NOx浓度的实际监测数据,分析了呼和浩特市大气污染物浓度变化的时空分布特征、大气污染与天气条件的关系。呼和浩特市市区主要以煤烟型污染为主,冬、春季比夏、秋季污染严重,采暖期比非采暖期污染严重,市区中心污染最严重。污染物的排放量及大气的稳定度状态是城市大气污染的主要影响因子,天气变化是城市大气污染物浓度变化的主导因素,局地环流是决定城市污染物分布的关键因素。因此,不同季节排污量的变化、天气条件是制作呼和浩特市大气污染预报的主要依据。

关 键 词:呼和浩特市  天气气候  大气污染物  时空分布特征  城市大气污染  大气污染预报  浓度变化  天气条件  空气污染物  2002年  NOx浓度  煤烟型污染  污染物分布  监测数据  非采暖期  影响因子  主导因素  天气变化  局地环流  TSP  市区  SO2

Abstract:The features of spatial-temporal distribution of air pollutants in the urban area of Hohhot were analyzed using the monitoring data of pollutant density such as TSP, SO 2 and NOx in the urban area from 1990 to 2002 to study the relationship between pollutant density and meteorological conditions. Results show that the dominant pollutant in Hohhot is smoke; pollution is more serious in spring and winter than in summer and fall, similarly more serious in the heating period than in the non-heating period. The air pollution in the central Hohhot is most serious. The amount of pollutant emission and the atmosphere stability state are major factors that influence air pollutants in the urban area. The weather change is the dominant factor of the urban air pollution density change. The local circulation is also a key factor influencing pollutant distribution. Therefore, the variations in exhaust gas in different seasons along with weather conditions constitute the basis of Hohhot air pollution prediction.
Keywords:air pollution  pollutant emission  weather condition  local circulation
