This study investigated the structure and function of macrobenthic community in Bohai Bay upon improvement of water quality due to pollution abatement. A total of 166 species were collected in the summer and autumn sampling, with an increase in sensitive species recorded as compared to data from previous studies. While historical variations in species richness indicated signs of improvement in community structure, results of functional diversity indices revealed that the macrobenthic community in Bohai Bay was still in an early stage of recovery. From BIO-ENV analysis, habitat instability may hinder how community responded to water quality improvement. Results of the benthic habitat quality assessment also indicated that the ecological status in most areas of Bohai Bay was classified as good, while a few estuarine regions were categorized in a poor status.
本研究调查了由于污染减排而导致水质改善后渤海湾大型底栖动物群落的结构和功能。在夏季和秋季的采样中共采集到 166 种，与以往研究的数据相比，记录到敏感物种有所增加。虽然物种丰富度的历史变化表明群落结构有所改善，但功能多样性指数的结果表明，渤海湾的大型底栖动物群落仍处于恢复的早期阶段。从 BIO-ENV 分析来看，生境的不稳定性可能会阻碍群落对水质改善的响应。底栖生境质量评估的结果还表明，渤海湾大部分地区的生态状况被评为良好，而少数河口地区则被归类为较差。
