This study aims to develop a multi-metric, fish-based Index of Biological Integrity (IBI) for assessing the environmental quality of rivers in Hechi Prefecture, Guangxi Province, South China. Data on fish assemblage were collected via electrofishing We screened 21 candidate metrics representing attributes of fish assemblage. Among these, six metrics were finally selected for the IBI. It was shown that the fish-based biological integrity was good in Xiaohuanjiang River , fair in Hongshuihe, Longjiang and Dahuanjiang Rivers, but poor in Diaojiang River. The results of assessment were consistent with the actual situation of human disturbance. The assessment system constructed by this study could be used or used for reference in the area around Hechi. Biotic integrity assessment was an important means of water environment quality monitoring. To enable the biotic integrity assessment more scientific and more objective, much more research work is required to focus on the relationship between biotic integrity and environmental factors.
本研究旨在开发一种基于鱼类的多指标生物完整性指数（IBI），用于评估中国南方广西壮族自治区河池市河流的环境质量。通过电鱼法收集鱼类群落数据。我们筛选了21个代表鱼类群落属性的候选指标。其中，最终为IBI选定了6个指标。结果表明，小环江的鱼类生物完整性良好，红水河、龙江和大环江的鱼类生物完整性一般，而刁江的鱼类生物完整性较差。评估结果与人类干扰的实际情况一致。本研究构建的评估体系可在河池周边地区使用或供参考。生物完整性评估是水环境质量监测的重要手段。为使生物完整性评估更加科学、客观，还需要开展更多研究工作，重点关注生物完整性与环境因素之间的关系。
