摘要
叙述水环境容量基本概念,明确调查、研究和应用自然水体的生物净化作用对于保护和利用水资源的重大意义。以云南省湖泊水体的污染特征为例,在其水生生态系统中,存在极大的生物净化能力,如对各类生物体的结构稍加调整,即可提高湖泊自身的净化能力,并可获得可观的经济效益。
<Abstrcat>This paper narrates the basic concept of water environmental capacity. It is great important to research and apply biological purification of natural water body for protecting and using water resources. Taking the polluted characteristics of lake water bodies in Yunnan as an example, there is an utmost ability of biological purification in the aquicolous ecological system of the lakes. Slightly regulating composition of the living creatures, it is possible to improve self-purification ability of the lakes and to obtain considerable economic benefit.
