摘要
用综合指示生物评价法、4种常用藻类生物评价法及6种常用底栖动物评价法对2014年齐齐哈尔市水体进行评价进行Jaccard相似系数计算分析,比较评价结果的相似性。对评价结果相同的水体与理化指标确定的水体功能进行归纳,确定Ⅱ-Ⅲ类水体为轻污染;Ⅳ类水体为中污染;Ⅴ类-劣Ⅴ水体为重污染。
We calculated and analysed Jaccard similarity coefficients of evaluation results of water body of Qiqihaer city in 2014 with synthetic indicator biological evaluation method,four normal evaluation methods of alga and six normal evaluation methods of benthic animals. We summarized water body of same evaluation re-sults and water function determined by physical and chemical indicators to determine class Ⅱ-Ⅲ water as light pollution,class IV water as pollution,class V and worse as heavily polluted.
