能源消费产生的SO_2和工业烟尘排放量时空演变分析

能源消费产生的大气污染问题已严重危及人类的生存和发展,研究我国空气污染的时空变化,关系到国计民生问题。论文利用重心模型研究发现:①如果以1990年的SO2污染物重心(113.83°E、34.03°N)为起点,17 a来我国SO2污染物重心差不多是沿西南45°方向运动;②如果以1990年的烟尘污染物重心(115.52°E、36.18°N)为起点,17 a来我国烟尘污染物重心差不多是沿西南45°方向运动;③上述两大污染物运动规律是由于17 a来我国能源消费重心差不多也是沿西南45°方向运动,同时还与中西部地区技术水平落后有关。

Analysis of Temporal and Spatial Evolution of SO_2 and Industrial Dust Emissions of Energy Consumption

Air pollution resulting from energy consumption has been a serious problem threatening human survival and development, the research which is about time and spatial change of air pollution is related to people's livelihood. Based on centre of gravity model, the study draws the following conclusions: 1) If we take centre of gravity of SO_2 pollutant in 1990 as a starting point, which is located at 113.83°E and 34.03°N, then we can find that centre of gravity of SO_2 pollutant of China has been moving towards southwest at 45° among the 17 years. 2) If taking centre of gravity of smoke pollutant in 1990 as a starting point, which is located at 115.52°E and 36.18°N, then we also find that the centre of gravity of smoke pollutant has been moving towards southwest at 45° during the 17 years. 3) The two laws of centre of gravity came into being because centre of gravity of China's energy consumption has been moving towards southwest at 45°, and also caused by the technical level lagging behind in central and western regions compared to that in eastern region.
