水环境非点源污染的模型模拟

The non-point source pollution model of water environment

由于水环境非点源污染问题越来越受到人们的重视 ,非点源污染模型得以快速发展 .首先简介了非点源污染模型的基本概念 ,然后把模型的研究发展历程划分为三个阶段 ,并分别进行了回顾 .为了给模型的应用者提供一个简单的选择依据 ,文中把常用的一些模型进行了比较研究 .最后还系统分析了当前模型的不足之处 ,概括了其研究和发展的趋势 。

Because the non-point source pollution of water environment is receiving more and more attention, the development of non-point source pollution models is thriving. The fundamental concepts of the models were briefly introduced in this paper, and then the course of the models' evolution, which had been divided into three phases, was reviewed. Some models, which are in common use, were compared in order to make it easy to select a suitable model. Moreover, the deficiency of the model study and the future trend were analyzed in the paper too. Finally, according to the actuality of study of non-point source pollution model in China, necessary proposals were put forward.
