收集整理了 2011-2021 年辽宁省 47 个点位的水质理化监测数据和大型底栖无脊椎动物定量监测数据,水质理化监测数据 27 368 个,大型底栖无脊椎动物样本总量 632 个,定量监测数据 3 180 个.合计监测到大型底栖无脊椎动物4 门 9 纲 23 目 85 科 188 属 297 种,以水生昆虫为主(226 种),占总种类数的 76.1%;其次为软体动物、环节动物和甲壳动物,分别占 12.5%、7.1%和 4.0%;扁形动物仅 1 种,占 0.3%.采用累积百分位数法、直接引用法和专家经验法,修订了辽宁省 85 科 188 属(合计 273 个)大型底栖无脊椎动物耐污值.其中,通过计算法得到耐污值 135 个,直接引用其他地区已建立的耐污值 100 个,根据专家经验确定耐污值 38 个.采用参照点位和受损点位的 BI 箱线图法对该研究和以往辽宁省建立的大型底栖无脊椎动物耐污值数据进行判别能力分析,结果表明,通过计算法确定的耐污值能更好地反映不同环境梯度,其适应性好于仅仅通过专家经验法确定的耐污值.
Study on the Revised Tolerance Values of Benthic Macroinvertebrate Taxa in Liaoning Province
The water quality physical and chemical monitoring data and the quantitative monitoring data of benthic macroinvertebrate from 47 sites in Liaoning Province from 2011 to 2021 were collected and collated.There were 27 368 water quality physical and chemical monitoring data,and 3180 benthic macroinvertebrate quantitative monitoring data from 632 samples.In total,4 phyla,9 classes,23 orders,85 families,188 genera,297 species of benthic macroinvertebrate were detected.There were 226 species of aquatic insects,accounting for 76.1%of the total species.Mollusks,annelids and crustaceans accounted for 12.5%,7.1%and 4.0%,respectively.There was only one species of platyhelminth,accounting for 0.3%.The tolerance values of 273 benthic macroinvertebrate taxa from 85 families and 188 genera were revised by cumulative percentile method,direct reference method and expert experience method.Among them,135 were obtained by calculation,100 were directly referenced from other areas,and 38 were determined according to expert experience.The discriminant ability analysis of this study and previous studies about tolerance values of benthic macroinvertebrate taxa in Liaoning Province was carried out by BI boxplot of reference sites and damaged sites.The results showed that the tolerance values determined by the calculation method could better reflect the different environmental gradients,and its adaptability was better than that determined by the expert experience method only.
