宁波姚江藻类生长规律的探讨

Growth Rules of Algae at Yaojiang,Ningbo

随着水体富营养化的不断扩大,其恶果也越来越显严重了,为了更好的保护宁波"母亲河",需要针对宁波姚江的水质建立模型。因为防止水体富营养化的唯一办法是维持水体氮、磷等主要营养元素收支平衡,所以治理富营养化的根本办法是从水体中移走过量的氮、磷等主要营养元素。建立了一个可以较准确的模型解释姚江藻类生长规律,但很多因素不同,导致刘载文等的模型缺乏针对性,无法很好解决姚江水体问题。因此针对姚江作了一些纠正和修改,提取一些措施。

With the expansion of water- body eutrophication, the consequences have become increasingly serious. To better protect our mother river, a model of water quality at Yaojiang, Ningbo is called for. It is believed that the only way to prevent water eutrophication is to keep in balance water nitrogen, phosphorus and other major nutritional elements. Therefore, the fundamental way to control the eutrophication is to remove excessive main nutrient elements such as nitrogen and phosphorus. This paper establishes an accurate model to explain the algae growth rules there. As the original models by Liu Zaiwen and others are inaccurate and fail to solve the water body problems, some corrections and modifications are made and measures introduced in the paper.
