摘　　要：为系统评价温榆河公园流域水生态状况,2021年对温榆河公园大型底栖动物进行了调查,分析了大型底栖动物的群落特征及时空分布,利用生物指数(BI)、生物多样性指数和大型底栖动物完整性指数(B-IBI)3种方法分别评价了温榆河公园水生态状况。结果显示,温榆河公园共采集到大型底栖动物56属种,隶属5类,不同物种大型底栖动物的密度与物种数在时空分布上存在差异,水生昆虫类具有显著优势,在多数点位占比超过50%;研究区域的多样性指数评价显示温榆河公园的物种组成相对比较丰富,而且已经有多个点位出现了指示清洁的优势种,说明温榆河公园的水生态状况在逐渐变好。通过对比与相关性分析,总结出适合评价温榆河公园的水生态状况的方法为多样性指数评价法。To systematically evaluate the water ecological status of the Wenyu River Park basin,the macrobenthos in Wenyu River Park were investigated in 2021.The community characteristics and temporal and spatial distribution of benthos were analyzed.3 methods were used to evaluate the water ecological status of Wenyuhe River Park,namely,biological index(BI),biodiversity index,and benthic integrity index(B-IBI).The results showed that a total of 56 genera and species of benthos were collected in Wenyuhe Park,belonging to 5 categories.The density and number of benthos of different species were different in temporal and spatial distribution.Aquatic insects had significant advantages,accounting for over 50%in most points;The evaluation of diversity index in the study area showed that the species composition in Wenyu River Park was relatively rich,and several sampling sites had already shown the presence of indicator species for clean water,suggesting an improvement in the water ecological condition of the Wenyuhe Park.Through comparison and correlation analysis,the method suitable for evaluating the water ecological status of the Wenyu River Park was concluded as the diversity index evaluation method.
