摘要: 根据呼玛河25个采样点(9个参照点,16个干扰点)的大型底栖动物和水体理化指标数据,采用底栖动物完整性指数(B-IBI),对寒温带山区河流进行健康评价。基于27个生物指标的分布范围、判别能力和相关性分析,最终确定由襀翅目个体相对丰度、EPT个体相对丰度(Ephemeroptera、Plecoptera、Trichoptera,EPT)、敏感类群个体相对丰度、BI指数(biotic index)和撕食者个体相对丰度构成B-IBI体系。采用比值法统一指标量纲,基于参照点B-IBI值分布的25%分位值作为健康评价标准。结果表明:25个采样点中8个为健康,8个为亚健康,6个为一般,2个为较差,1个为极差。B-IBI体系表明:呼玛河健康状况总体较好;其中干流健康状况从优至劣依次为上游、中游、下游;各支流中干部河、瓦拉干河、大西鲁嘎河、奥库萨卡埃河和西里尼西河处于健康状态,塔河、小西鲁嘎河和倭勒根河处于亚健康状态,穆五鲁河和曼拉开河处于一般状态,海莱河和塔哈河处于较差状态。Pearson相关性分析表明,B-IBI值与溶解氧呈显著正相关,与氨氮呈显著负相关(P<0.05)。冗余分析表明,B-IBI体系对环境因子具有较高的解释度。以呼玛河为例建立的BIBI体系适用于我国寒温带山区河流健康评价。

Abstract: Based on the data of benthic macrobenthos and water physicochemical indices of 25 sampling points (9 reference points and 16 disturbed points) in Huma River, the benthic index of biotic integrity (B-IBI) was deve-loped to evaluate the health of mountain river in the cold temperate zone. According to the distribution range, discriminant ability, and the correlation analysis of 27 biological indicators, the final B-IBI system was composed of the relative abundance of Plecoptera individuals, the relative abundance of EPT (Ephemeroptera, Plecoptera, Trichoptera) individuals, the relative abundance of sensitive taxa individuals, the biotic index  (BI), and the relative abundance of shredder individuals. The ratio method was used to unify the index dimensions. The 25% quantile of the B-IBI value distribution at the reference points was used as health evaluation standard. The results showed that eight out of the 25 sampling points were healthy, and the number of points with status of sub-healthy, fair, poor, and very poor was 8, 6, 2, and 1, respectively. The B-IBI system showed that the health status of the Huma River was generally good. The health status of the trunk stream from good to bad was: upstream, midstream, and downstream. Among tributaries, Ganbu River, Walagan River, Daxiluga River, Aokusakaai River and Xilinixi River were at healthy status; Tahe River, Xiaoxiluga River and Wolegen River were at sub-healthy status; Muwulu River and Manlakai River were at fair status; and Hailai River and Taha River were at poor status. Results of Pearson correlation analysis showed that the B-IBI value was significantly positively correlated with dissolved oxygen content and negatively correlated with ammonia nitrogen content (P<0.05). Results of redundancy analysis showed that the B-IBI system had a high degree of explanation for environmental factors. The B-IBI system based on the Huma River was suitable for health assessment of cold temperate mountain rivers in China.
