漓江中下游基于鱼类生物完整性指数的河流健康评价体系
Application of Index of Biological Integrity Based on Fish to Assess the River's Health in the Middle and Lower Reaches of Lijiang River

中文摘要：2014年4月-2015年1月,按季度对漓江中下游进行了4次鱼类物种采样调查,通过对22个初选指标的筛选,建立了基于鱼类生物完整性指数(IBI)的河流健康评价体系,最终确定了7个评价指标,即鱼类总物种数、鲤科鱼类占总类数的百分比、亚科鱼类种数、亚科鱼类种数、杂食性鱼类数量百分比、敏感性鱼类占总类数的百分比、耐受性鱼类占总类数的百分比。采用1、3、5赋值法计算各采样点IBI值,并将鱼类完整性划分为6个等级对河流进行评价,具体为:极好(58~60)、较好(48~52)、一般(40~44)、较差(28~34)、极差(12~22)、无鱼(0)。结果显示,漓江中下游以及各分段河流(桂林段、阳朔段、平乐段)的鱼类IBI总分均在40分以上,处于一般或一般以上水平。
英文摘要：Four quarterly samplings for fish species were carried out during the period from April 2014 to January 2015. By the filtration of 22 primary indices, the evaluation system was established on the basis of index of biological integrity (IBI) with 7 evaluation indices selected, including total number of species, ratio of cyprinid species with total number of species, the number of Gobioninae, the number of Coltrinae, ratio of omnivorous species with total number of species, ratio of sensitive species with total number of species, and ratio of tolerant species with total number of species. The IBI value of each sampling site was then calculated using 1, 3, 5 approximation of value assignment, and the values were classified into 6 levels to assess the biological integrity of fish: extremely good (58~60), good (48~52), normal (40~44), bad (28~34), and extremely bad (12~22), no fish (0). The results showed that, the IBI score of the middle and lower reaches of Lijiang River was over 40, as well as that in each river segment (Guilin segment, Yangshuo segment, and Pingle segment), indicated that an average level and above. 2016,(35): 288-293 收稿日期：2015-09-21 DOI：10.11984/j.issn.1000-7083.20150289 分类号：Q959.4 基金项目：国家自然科学基金(51379038, 51509042); 广西科学研究与技术开发计划项目(桂科攻1355007-14); 广西教育厅高校科学研究项目(YB2014151); 广西自然科学基金(2014GXNSFBA118072); 广西高等学校高水平创新团队及卓越学者计划项目(002401013001) 作者简介：丁洋(1991-), 男, 硕士研究生, 主要从事环境生态研究, E-mail:1101882622@qq.com *通讯作者：吴志强, 教授, 博士生导师, 主要从事鱼类生态学研究, E-mail:zqwu@glut.edu.cn 参考文献： 蔡德所, 王备新, 赵湘桂. 2009. 漓江流域水生态系统健康监测和评价体系研究[J].广西师范大学学报(自然科学版), 27(2): 148-152. 广西水产研究所, 中国科学院动物研究所. 2005. 广西淡水鱼类志 第二版[M]. 南宁: 广西人民出版社. 黄亮亮, 吴志强, 蒋科, 等. 2013. 东苕溪鱼类生物完整性评价河流健康体系的构建与应用[J]. 中国环境科学, 33(7): 1280-1289. 乐佩琦. 2000. 中国动物志 硬骨鱼纲 鲤形目(下卷)[M]. 北京: 科学出版社. 廖静秋, 黄艺. 2013. 应用生物完整性指数评价水生态系统健康的研究进展[J]. 应用生态学报, 24(1): 295-302. 刘恺, 周伟, 李凤莲, 等. 2010. 广西河池地区河流基于鱼类的生物完整性指数筛选及其环境质量评估[J]. 动物学研究, 31(5): 531-538. 孟伟, 张元, 渠晓东, 等. 2011. 河流生态调查技术方法[M]. 北京: 科学出版社. 郑海涛. 2006. 怒江中下游鱼类完整性评价[M]. 湖北: 华中农业大学.
