【摘要】 以阳泉市山底河流域四种常见的湿地植物水葱、芦苇、香蒲和莎草为例，通过盆栽试验，对比其在自来水和酸性老窑水中的生长和生理状况及体内S、Mn、Zn含量，并选用熵权TOPSIS评价法综合评价其对酸性老窑水的耐受性和污染物吸收能力，以此来探究四种植物对酸性老窑水的修复潜力。结果表明，在酸性老窑水的影响下，四种植物体内的S、Mn、Zn含量均高于对照组，香蒲和水葱的生长受到促进，芦苇和莎草的生长受到抑制；通过熵权TOPSIS评价法来评价四种植物的耐受性和对老窑水中污染物的吸收能力，有效避免了主观因素的影响，在四种植物中，香蒲对酸性老窑水的修复潜力最强。更多还原

【Abstract】 Four kinds of common wetland plants, Scirpus validus, Phragmites australis, Typha orientalis, Cyperus glomeratus Linn in Shandi River Basin of Yangquan City were taken as the research objects. By the pot experiment, to compare the growth and physiological conditions, as well as the contents of S, Mn and Zn in tap water and acid mine drainage, entropy weight TOPSIS was used to comprehensively evaluate the tolerance and pollutant absorptive capacity. And then the remediation potential of the four plants to acid mine drainage was discussed. The results show that under the influence of acid mine drainage, the contents of S, Mn and Zn in the four plants were higher than those in the control group, and the growth of Typha orientalis and Scirpus validus were promoted, while that of Phragmites australis and Cyperus glomeratus Linn were inhibited. The tolerance of the four plants and the ability to absorb pollutants in the acid mine drainage were evaluated by entropy weight TOPSIS, which effectively avoided the influence of subjective factors. The Typha orientalis had the strongest repairing potential to acid mine drainage among the four plants.更多还原
