摘要
美国环保局(EPA Environment Protection Agency)最早于1972年的《清洁水法》中提出 TMDLs(Total Maximum Daily Loads),TMDL为最大日负荷总量。在美国实施TMDL计划后,在点源和非点源污染综合控制方面成效显著;重点介绍其计划背景、发展进程、组成框架。
TMDL （Total Maximum Daily Loads） was required by the Clean Water Act since 1972. It is playing a more and more important role in maintaining and regaining sound water quality. The background, development and framework of a TMDLs program are introduced in this article.
