摘要
根据1983—1987年间对京津及邻近地区河流、水库、湖泊的大型底栖无脊椎动物调查资料,利用Shannon多样性指数和指示生物类群进行水体质量生物学评价,可以比较准确地把水域划分成清洁、轻污、中污、重污和严重污染五个等级。其中清洁、轻污水体主要分布在本区西、北部的山区,而中污、重污和严重污染水体则主要分布在本区东南部分的平原地区。京津城市化活动是水质恶化的主要影响因素,因此强调城市污水和工业废水排入环境前应当加以处理。
The bioassessments of water quality by using Shannon's diversity index and indicator organisms of macroinvertebrates have been carried out around Beijing, Tianjin and adjacent area during 198S'-1987. The results obtained indicate that the joint indicator of diversity index and species indicator of benthic macroinvertebi ates can be satisfactorily used to evaluate and classify the status of water quality into 5 classes i.e. clean water, light pollution, moderate pollution, henvy pollution and serious pollution in this area. Most of the clean and light polluted waters are distributed in mountain area in the north-western and the heavy and serious pollution in the plain area in the south-eastern of this research scope. The urbanization is the major influence factor on water quality. So to treat and improve the urban sewage and industrial waste water quality come from Beijing and Tianjin city before discharging into environment must be emphasized.
