| 摘 要： | F-IBI（fish index of biological integrity，鱼类生物完整性指数）和B-IBI（benthic-macroinvertebrate index of biological integrity，底栖动物生物完整性指数）在大尺度流域范围内应用较广，但在城市水体中的应用研究较少.为了解F-IBI和B-IBI在城市水体中的适用性，分别于2014年和2015年的5月、8月和10月分6次对济南市水体进行野外采样调查，共设46个采样点（其中，12个采样点位于水库，34个采样点位于河流），采集底栖动物和鱼类，并测定了23个水环境因子.依据生物物种丰富度、种类个体数量比例、敏感性和耐受性、营养结构、繁殖共位群、物种多样性等功能属性，共计算底栖动物生物参数27个、鱼类生物参数22个.采用箱体图法和累计系数法，分别对河流型水体和水库型水体的生物参数进行筛选.根据百分位数法，共划分健康、较好、一般、较差、极差5个等级.通过Pearson相关性检验法判定鱼类和底栖动物评价结果的一致性.结果表明:①底栖动物总分类单元数、BMWP指数、鱼类物种数、鱼类个体数为河流型水体和水库型水体共同核心参数.②鱼类评价结果显示，健康样点6个、较好样点7个、一般样点9个、较差样点12个、极差样点12个，底栖动物依次分别为6、6、8、17、9个.③F-IBI和B-IBI相关系数为0.56，相关性较为显著.研究显示，济南市南部黄河区、小清河区东部生物完整性较高，城区东部及北部徒骇马颊河区生物完整性较差，鱼类和底栖动物评价结果具有较强的一致性.

| Abstract: | The fish and benthic macroinvertebrate indexes of biotic integrity (F-IBI, B-IBI) are widely used indicators showing the condition of large-scale catchment freshwater in the world. However, these indexes are less used to evaluate the freshwater condition in urban area. In order to understand the applicability of F-IBI and B-IBI for the urban aquatic system, 46 sampling sites including 12 reservoir sites were investigated in Jinan City during May, August and October from 2014 to 2015. The dataset included fish and benthic-macroinvertebrate assemblage as well as 23 physiochemical factors. Based on the attributes of richness, composition of biotic abundance, sensibility and tolerance, nutrition structure, reproductive guild and biodiversity, 27 benthic-macroinvertebrate metrics and 22 for fish were selected as the candidate metrics. The methods of box-plots and cumulative coefficient were used to determine the core metrics to evaluate the healthy condition of rivers and reservoirs, respectively. The sampling sites were divided into five classes, including excellent, good, moderate, poor and bad by the percentile method. The Pearson correlation test was used to validate the correlation between F-IBI and B-IBI. The results showed: (1) Four metrics including benthic-macroinvertebrate richness, BMWP, fish richness and fish numbers were selected as the core metrics for both rivers and reservoirs, which is reasonable; (2) In terms of F-IBI, the number of excellent, good, moderate, poor and bad sites was 6, 7, 9, 12, 12, respectively, and it was 6, 6, 8, 17, 9 for B-IBI; (3) F-IBI and B-IBI had a significant correspondence with correlation coefficient of 0.56. This study showed that fish and benthic-macroinvertebrate community exhibited higher integrity in the southern and eastern parts of Jinan City than that in other regions. However, the sites located in the northern and central part of Jinan City showed poor and bad condition depending on F-IBI and B-IBI. F-IBI and B-IBI showed a strong spatial correlation in Jinan City. |
