摘　　要：在探讨目前国内外水生态系统评价方法的基础上,采用B-IBI法评价鄱阳湖水生态系统健康性,分析认为,底栖生物参数差异性与水体理化环境相关性不明显,提出将GIS与B-IBI法耦合使用进一步提高评价结果的精度,并以鄱阳湖为研究对象验证此法的精度,结果表明:GIS与B-IBI法耦合使用评价结果较好,误差在±10%范围内;鄱阳湖水生态系统总体处于亚健康-健康状态;长江口段及周溪镇段水生态系统较差,处于病态-亚健康状态,说明开展水生态修复工程迫在眉睫。评价结论对鄱阳湖管理部门制定水生态修复方案具有一定参考意义。Based on the discussion of present domestic and international evaluation methods for aquatic ecosystems,method of B-IBI is applied to the ecosystem health evaluation of Poyang Lake. Since correlation is not obvious between benthic parameter differences and physical-chemical environment. Therefore,method that GIS combined with B-IBI used in Poyang Lake in order to improve the accuracy of evaluation results. The results show that the combination of GIS and B-IBI can give arelatively accurate result with the error of ± 10%. The aquatic ecosystem of Poyang Lake is overall in sub-healthy to healthy status. The ecosystems of Yangtze estuary section and Zhouxi Town section are in morbid to sub-healthy status,which indicate that carrying out aquatic ecosystem restoration project is imminent. The evaluation results have a certain reference significance for management departments of Poyang Lake to develop ecological restoration programs.
