-
摘要: 由于我国现行水质标准中关于富营养化指标的制定缺乏基于营养物基准的分析研究,急需通过借鉴国外经验,找出适宜方法。介绍了美国和其他发达国家的营养物标准体系,回顾了美国国家环境保护局(US EPA)及各州和部落采用的不同营养物标准的制定程序和技术方法,重点分析了国外营养物标准指标的选取和确定标准值的方法。从湖泊营养物基准入手,探讨了制定我国湖泊营养物标准的方法及技术。Abstract: Lake eutrophication has been one of the most prominent environmental problems in China in recent years. Current water quality standard in China is short of nutrient standard system on account of nutrient criterion. It is badly in need of establishing nutrient standard system appropriate to China’s socioeconomic situations. Due to the lack of research on nutrient criteria in water quality, foreign experience may be helpful. The nutrient standard systems of the USA and other developed countries were introduced, and the procedure and technical methods to develop lake nutrient standards of USEPA and several states reviewed. The methods to select the nutrient variables and to determine the standard levels in foreign countries were focus. Finally, the methods and techniques of nutrient standard establishment based on nutrient criteria in China were discussed.
