摘要
对湖泊富营养化状态的有效评价是对湖泊进行有效管理的重要手段之一。针对富营养化评价中的不确定性,拟采用概率方法——贝叶斯方法对富营养化状态进行评价。以水利部水利水电规划设计总院提出的《地表水富营养化控制标准》为评价标准,选取Chla、TP、TN、CODMn、SD5个指标,对我国19个湖泊应用贝叶斯方法进行富营养化评价,并应用两个实例对该方法在富营养化评价中的有效性进行了验证。结果表明,贝叶斯方法应用于湖泊富营养化评价具有简单、实用的特点。
The evaluation of the lake eutrophication state is one of the important and efficient supervision means. The Bayes method is used to the indetermination of the lake eutrophication evaluation. Nineteen lakes in China are evaluated with five indicators including Chla, TP, TN, CODMn and SD. The water quality control standard for the surface water eutrophication is put forward by the Planning and Design Institute of the Water Resources and Hydropower. Two examples are checked for the validity of Bayes method in the evaluation of the lake eutrophication. As a result the Bayes method is easy and practrical in the evaluation of the lake eutrophication.
