河流健康研究进展与前瞻

河流健康研究是目前河流生态学领域研究热点之一。首先介绍了河流健康概念的产生、发展及其不同的内涵，辨析了河流生态系统健康、流域生态系统健康概念与河流健康概念的区别与联系，认为河流健康是指河流既能保持河流生态系统完整性，又能维持其对人类社会提供的各种服务功能。在分析河流健康内涵的基础上，着重回顾分析了国内外河流健康评价的实践情况以及河流健康评价方法，根据河流健康评价方法的评价原理，河流健康评价方法主要分为预测模型法和多指标方法。针对目前河流健康研究领域存在的主要问题，提出了河流健康研究的发展方向，认为今后开展河流健康评价研究还需在评价指标选取、评价标准确定、评价尺度选取以及河流健康评价与河流管理集成等方面进一步加强。

RESEARCH ADVANCE IN RIVER HEALTH

The research of river health is one of the hotspots in the current field of river ecology research.The generation,development and various connotations of river health are introduced firstly and the concepts of river ecosystem health,watershed ecosystem health and river health are distinguished.River health is that river can both keep its integrity and maintain various service functions providing the society.This review focuses on the practical research and the methods of river health assessment based on the analysis of the connotation of river health.The methods of river health assessment are divided into predictive model method and multivariate statistical method based on their principle.Aiming at the main existent problems in this field,the future development trend of river health research is put forward.It is suggested that the further study of river health should be emphasized on aspects of choice of assessment indicators,establishment of assessment standards,choice of assessment scale and the integration of river health assessment and river management.
