摘要
从生态系统健康的概念入手,通过对生态系统健康评价方法的研究和分析,对底栖动物尤其是大型底栖无脊椎动物在生态系统健康评价中的作用进行了分析和总结。生物监测法和多指标评价法是水生态系统健康评价的主要手段,而利用指示物种、预测模型和底栖生物的完整性指数等多种方法可以对水生态系统健康进行快速和准确的评价。如何完善底栖动物在生态系统健康评价中的作用并综合运用其他评价技术,以及结合评价结果对受损水生态系统进行生态修复和重建将是这一领域未来研究的重点所在。
Based on the conception of ecosystem health, the roles of benthos, especially for macroinvertebrates in the aquatic ecosystem health assessment are summarized and presented in the paper. Results showed that biological monitoring and multi-indicators method are the two primary methods for aquatic ecosystem health assessment. Methods of indicative species, predictive models and biological integrity of benthos can be employed to assess aquatic ecosystem health rapidly and precisely. Furthermore, it is important to strengthen the multidisciplinary comprehensive approaches, consummate the applications of benthos for ecosystem health assessment. And based on the assessment conclusion, an applicable restoration and rebuilt for the impaired ecosystem may be the keypoint in the future studies.
