摘要
以湖南省1990-1999年的SO2监测和统计数据为基础,对湖南省排放SO2的现状进行了分析,计算了湖南省各地区SO2排放强度,并对湖南省今后SO2排放趋势进行了预测.结果表明,湖南省SO2污染最为严重的地带是处于沅江和澧水流域的吉首和洪江南北走廊带,其次是以长沙为中心的湘江谷地;排放强度最大的区域位于湖南省中部的娄底、湘潭和株洲等地,排放强度大于10.0t/km2·a,其次是岳阳,排放强度在7.50～10.0t/km2·a之间.预测结果显示,湖南省SO2排放量在2005年将达到77.15×104t,到2010年将达到92.41×104t.
Hunan Province, situated in central-south China, is the key region of sulfur dioxide control zone and acid rain control zone. The present situation and the intensity of sulfur dioxide emission were analyzed and estimated in this paper based on the monitoring data and the statistical data from 1990 to 1999. Also, the trend of sulfur dioxide emission in the future in Hunan Province was predicted. The results show that the severest pollution regions are Jishou and Hongjiang Cities, which are situated in the upper reach of the Yuanjiang River and the Lishui River. The second most severly polluted region is the Xiangjiang River valley surrounding Changshacity. The regions with the greatest intensity of sulfur dioxide emission are Loudi, Xiangtan and Zhuzhoucities, which are situated in the central part of Hunan Province, with an intensity larger than 10.0 t/km^2·a, and the next is Yueyangcity with an intensity from 7.50 to 10.0 t/km^2·a. The predicted results show that the amount of sulfur dioxide emission in Hunan Province will rise up to 771.5 thousand tons in 2005, and 924.1 thousand tons in 2010.
