摘　　要：为定量分析区域水环境污染压力的大小,构建了污染足迹计算模型,针对山西省的水环境污染问题,计算了山西省2011-2020年水污染足迹和水污染承载力,并对山西省的水环境污染压力进行了研究分析。结果表明:10年间,山西省人均水污染足迹波动下降,总降幅34.3%;氨氮的排放对水域生态空间的占用大于化学需氧量;人均水污染承载力逐年上升;水污染呈现赤字状态,但总体呈下降趋势;万元GDP水污染足迹在2011-2015年有所上升,2015-2020年快速下降,降幅达60.6%;水污染生态压力指数均?3,处于重度压力状态,但2015年之后明显缓解。In order to quantitatively analyze the size of regional water environment pollution pressure,a pollution footprint calculation model was constructed.Aiming at the water environment pollution problem in Shanxi Province,the water pollution footprint and water pollution carrying capacity of Shanxi Province from 2011 to 2020 were calculated,and the water environmental pollution pressure of Shanxi Province was analyzed.The results show that:in the past 10 years,the per capital water pollution footprint of Shanxi Province fluctuated and decreased by 34.3%;Ammonia nitrogen emissions occupied more ecological space than chemical oxygen demand;the per capita carrying capacity of water pollution increased year by year;water pollution is in deficit,but the overall trend is downward.The water pollution footprint per 10,000 yuan GDP increased from 2011 to 2015,and decreased rapidly from 2015 to 2020,with a decrease rate of 60.6%.The ecological pressure index of water pollution was greater than 3,which was in a severe pressure state,but it was significantly relieved after 2015.
