人口、经济(人均GDP和第二产业产值比重)及技术(城市化率和能源强度)等影响因素是污染物(COD和SO2)排放量的主要影响因素。因此STIRPAT模型分析认为湖南省主要污染物的排放量受全省人口、经济、技术等多方面因素的影响,其中人口规模影响作用最大,能源强度次之,其它因素的直接影响较小。
Population, economy and technology are the main factors which have impact on the emissions of COD and SO2. Therefore, analysis of STIRPAT model shows that the emissions of environmental pol- lutants in Hunan Province are influenced by many factors including population, economy ,technology and so on.
