区域水环境自净能力的定量评价

根据地震等级和风力等级的计算原理 ,提出了区域水环境自净能力等级的概念。它是描述一个地区水环境自净能力大小的定量指标。自净能力等级越高 ,区域水环境的自净能力越强。该指标从理论和应用方面来说都具有许多优点 ,概念明确 ,简单易行 ,具有重要的现实意义

Quantitative Evaluation on Self-purification of Water Environment of Area

According to the calculating principle of wind scale and earthquake magnitude,the concept of the magnitude of self-purification capacity of water environment of area was put forward.It was a quantitative target for describing of self-purification capacity of water environment of area.The higher the magnitude of self-purification capacity was,the greater the self-purification capacity of water environment of area was.It had a great many of merits in regard to theory and application.Its concept was explicit and its application was easy,which had practical significance.
