摘要：酸性矿山废水中低的pH和高浓度的重金属对水生态系统影响巨大。依据"参照(Control)-受损(Impaired)-恢复(Recovery)"的设计方法,对高岚河受酸性矿山废水影响的河段、不受影响的河段及恢复河段进行对比分析。结果表明底栖藻类密度、叶绿素a浓度、无灰干重及自养指数等受酸性矿山废水影响明显,且枯水期酸性矿山废水的影响更显著。相关分析表明自养指数与各金属显著正相关而与pH值显著负相关,可以很好地指示矿山酸性废水对底栖藻类的影响。
The combination of low pH and high concentrations of metals associated with acid mine drainage would have severe toxicological effects on aquatic ecosystems. In order to evaluate the potential impact of acid mine drainage on the benthic algal communities in Gaolan River, which is one of the three main tributaries of Xiangxi River, we chose three sites in pyrite mining area as impaired group （ I）, four uninfluenced sites were taken as control group （ C ） and five sites as recovery group （R）. The results showed that benthic algal density, chlorophyll a concentration, ash free dry mass （AFDM） and autotrophic index （AI） were significantly affected by acid mine drainage from pyrite in the upstream of Gaolan River, while dry season affected seriously than flood season. Correlation analysis showed autotrophic index was positively correlated with metals and negatively correlated with pH, so AI could be a better indicator in the case where a pollutant such as acid mine drainages.
