摘要
武汉墨水湖30多年来因湖周大量城市污水的排入,造成湖泊严重富营养化,急需综合规划治理,因此需研究墨水湖水体污染变化规律,开展水质模型的研究。针对墨水湖水文、水质、地貌状况,把整个湖区划分五块（子湖区）,建立分散结构N/P水质模型,提出了一套可行的模型参数识别方法,并作了模拟检验,精度令人满意。在分析中运用系统论方法,并应用计算机现编程序操作。
Located in the southeast of Hanyang Prefecture of Wuhan, Moshui Lak e is a small-median-size lake with an area of 3. 35 km2 Being important water resources in local areas, it plays a key role in aquatic farming, irrigation and water supply. In the past 30 years, nearly 8000 tons of waste water per day was discharged into the lake as a result of industrial, agricultural development and population increase. The water quality in the lake is seriously deteriorated, which leads to growing eutrophication. Some parts of the lake are even getting dark or stenched. The neighboring peopie's health and the entertainments of Wuhan Zoo are threatened consequentially.To meet the urgent needs of comprehensive regulation, control and planning for Moshui Lake, we set up here a N/P water quality model after the pollution sources in Moshui Lake surveyed and its water quality assessed. First Moshui Lake is divided into 5 subareas, each of which contains several small parts. Then in each subarea a scattered structure of N/P model is built, and the parameters of each model are identified respectively. The accuracy of calculation by means of PC-1500A is satisfactory. Finally the systematical theory is introduced in the analysis. The whole calculation is operated by programming computer language.The model building and parameter Identification are advantageous in this method, so it is hopefully convenient for more practical applications.
