水环境容量计算方法研究

The Comparison of the Environmental Capacity Calculation Methods

提出了一维稳态条件下计算水环境容量的３ 种方法，即段首控制方法、段尾控制方法和功能区段尾控制方法。通过对渭河干流环境容量的计算，分析比较了各方法的优劣及其相互联系，阐明了各方法的物理含义及其适用条件。计算结果证明了各方法的可靠性。

This paper suggests three kinds of methods for dalculting water environmental cpacity in the case of one demensional ie. the section endig control method in the functional section. Through the comptation of the environmental capacity of the main stream of the Wei River and the analytical coparison of the dvantages and disadvantages of each method and their interconnections, it also deals with the physical connotations as well as the adoptable conditions of each method. Meanwhile, the calculated results are used to check and identify each method, indicating that all the methods are feasible reliable.
