河流健康生物指标浅析

Analysis of biological indicators of river health

随着经济的迅速发展、城市化进程的不断加快和人口数量的快速膨胀,人类对河流的干扰日渐增加,河流的健康问题日渐凸显并已在全球引起广泛重视。河流管理从单一的污染防治及工程整治向综合考虑水体修复与生态保护的河流生态系统管理方式转变,旨在从水质、生物、生态等众多角度综合评估河流系统状况、改进河流管理的河流健康概念得以提出并受到更多的关注,已经成为河流或流域管理的国际趋势。对河流进行保护和修复的前提是必须先判断和评价河流是否处于健康状态,由此,河流健康评价研究日渐成为研究热点。

With the rapid development of the economy, the accelerating process of urbanization and the rapid expansion of the population,the interference of human to the river has been increasing,the river health problem becomes increasingly salient and has attracted wide attention in the global world. River management has evoluted from focusing on economic benefits and river construction works to a comprehensive view of river restoration and ecologieal peotection.River health has been applied to the assessment of river condition and becomes more than just a rhetorical tool. The premise of the protection and restoration of the river is must first to judge and evaluate whether the river is in a healthy state. Thus,evaluation of river health is increasingly becoming a research hotspot.
