    摘要:

    基于2014年5—6月对济南市4个生态区中48个采样点的底栖动物和水环境调查结果,采用多元统计分析以及干扰程度最小原则构建底栖动物生物完整性指数B-IBI的参照系统,按河流型和水库型样点分别构建IBI指数。通过对28个候选生物参数进行判别能力和相关性分析,确定了河流型B-IBI的4个构成指数:水生昆虫分类单元数、甲壳动物和软体动物个体百分比、BI指数、BWMP指数,以及水库型B-IBI的3个构成指数(水生昆虫分类单元数、优势分类单元数百分比和多样性指数)。采用比值法统一量纲,分别构建了河流型和水库型B-IBI指数,利用其B-IBI值对济南市水生态健康状况进行评价。结果表明:河流型36个样点中各有7个处于极差和较差状态,11个为一般,8个为亚健康,3个为健康。12个水库样点中有1个为健康,6个为亚健康,4个为一般,1个为极差;黄河区健康状态最好,城区最差。影响底栖动物群落的重要环境变量是水体中氮含量和城建用地百分比。

    Abstract:

    The benthic-index of biotic integrity(B-IBI)was used to evaluate the health status of aquatic ecology in Ji’nan City. Benthic macro-invertebrate assemblages and the aquatic environment were sampled from four ecoregions of 48 sites in the city from May to June, in 2014. Based on multivariate statistical analysis and the principle of least interference, the reference system of B-IBI was built. The B-IBI was developed for river points and reservoir points, respectively. The analyses of the judgment ability and Pearson correlation were conducted on 28 candidate biotic metrics. The core metrics of B-IBI for river points were determined to be four indices: the number of aquatic insect taxa, relative percentage of Crustaceans and Molluscs, BI index, and BWMP index. The metrics of B-IBI for reservoir points included the number of aquatic insect taxa, percentage of advantage number of taxa, and diversity index. The B-IBI values for river and reservoir points, which were transformed into uniform scores by the ratio score method, were obtained. The results show that of the 36 river sampling sites, seven sites were at unhealthy or extremely unhealthy status, 11 sites were at moderately healthy status, eight sites were at sub-healthy status, and three sites were at healthy status. Of the 12 reservoir sampling sites, one site was at healthy status, six sites were at sub-healthy status, four sites were at moderately healthy status, and one site was at extremely unhealthy status. The health status was best in the Yellow River ecoregion and worst in the urban region. The major environmental variables that affected the macro-invertebrate assemblages were the nitrogen content and the percentage of urban construction land.
