| 中文摘要: |
| 为给水源地水库的生态风险评估提供科学依据和决策支持,根据浙江省和湖北省几个典型水库的调查数据,构建了底栖动物完整性指数（B-IBI）。参考相关文献及调研选取了32个备选参数,经统计分析筛选出8个指示能力较强的参数,构建B-IBI指标体系,分别为香侬-维纳多样性指数（Shan2）、捕食者类群数量百分比（Pred-Pct）、寡毛类物种数百分比（%OligoTax）、非水生昆虫数量百分比（NonInPct）、Hilsenhoff生物指数（HBI）、收集者物种数百分比（%CllctTax）、收集者数量百分比（CllctPct）和平均物种数量（RichnessPerTaxon）。确立了水库生态系统健康评价标准,并与潜在环境梯度进行了相关性分析。结果表明,该指数很好地反映了潜在环境梯度,用于供水型水库的水生态系统健康评估较为合适。 |

| Based on the survey data collected in the several typical reservoirs，the authors developed a zoobenthos-based index for biological integrity with the aim to provide scientific and decision-making supports for ecological risk assessment on drinking water resources-based reservoirs. A total of 32 candidate metrics were involved in the process of developing the B-IBI index system according to the published literatures. Eight metrics were selected by statistical analysis and joined into the final index system due to having good abilities on detecting stressor gradients，including Shannon-Wiener diversity index(Shan_ 2)，the percentage of predator individuals(PredPct)，the percentage of oligochaetestaxa(%OligoTax)，the percentage of non-aquatic insects individuals(NonInPct) ，Hilsenhoff biotic index(HBI)，the percentage of collector taxa(%C11ctTax)，the percentage of collector individuals(C11ctPct) and the average number of species(RichnessPerTaxon).The evaluation criteria about reservoir ecosystem health were established and the relation analysis was performed between the B-IBI scores and latent environ-mental gradients. The results indicated that this index worked well to reflect the latent environmental gradients，and would be suitable to the assessment study on ecosystem health of drinking water resources-based reservoirs. |
