摘要
选取2001—2015年的相关数据,根据生态位态势理论,建立重点行业的大气环境经济综合效率生态位模型,分析了电力行业等江苏省大气污染重点行业SO2和烟粉尘的环境经济污染综合效率生态位,同时利用适宜度模型,基于生态位模型,对江苏省大气环境负荷的程度进行了评价。结果表明:①2002—2015年,重点行业SO2生态位较低的行业为电力行业、非金属行业和化学工业,烟尘生态位较低的行业为电力行业、非金属行业和木材加工行业;②与2002年相比,2015年三大产业的SO2和烟尘生态位均呈上升趋势,烟尘生态位的“绝对值”呈上升趋势;③对SO2、烟尘生态位较低的产业与生态位较高的产业进行对比分析,二者的生态位差呈现出波动上升趋势;④江苏省“十一五”期间大气环境负荷较高,“十五”和“十一五”呈下降趋势,“十二五”呈上升趋势,2015年达到理想状态。
Based on thedata of 2001-2015, according to the theory of niche situation, a comprehensive ecological niche model associated with air environment for key industries was established, the comprehensive efficiency of the key industries of air pollution was analyzed, at the same time, based on the fitness model, the atmospheric environmental load based on niche model was evaluated. The results showed that in the past 2002-2015 years, the low niche industries of SO2 in the key industries are electric power industry, non-metallic industry and chemical industry, the lower ecological niche of smoke and dust is power industry, non-metal industry and wood processing industry.Compared to 2002, the SO2 and smoke dust niche of three industries increased and the "absolute value" of the niche was on the rise in 2015. A comparative analysis was conducted between the industries with lower SO2 and smoke dust niche and higher niche industries, the ecological potential difference of the two showed a trend of fluctuation and became bigger and bigger year by year.The atmospheric environment load of Jiangsu during the 11th Five-Year was relatively high, the 10th and the 11th Five-Year showed a downward trend, the 12th Five-Year was the rising trend, and reached the ideal state in 2015.
