潮汐河网水环境随机容量研究

根据潮汐河网水环境模型中水文及水质参数具有明显随机性的特点,本文建立了潮汐河网水环境随机模型,给出了随机参数的分布函数形式。用Monte-Carlo随机抽样法求解水项模型 当只抽一个样本时,随机模型的算法与确定性模型的算法一样。计算结果为水环境容量的分布函数,容量结果与保证率成一一对应关系。最后还对随机参数的分布函数形成进行了敏感性讨论。 

Study of Stochastic Total Allowable Loads of Tidal River Networks

Based on the stochastic characteristics of hydrologic and water quality parameters of water quality model of tidal river-network, this paper develops a water quality stochastic mathematical model suitable for calculating stochastic total allowable loads of tidal river-network. The form of stochastic distributed function have been given in this paper. The Monte-Carlo Method has been used to calculate the stochatic model. The algorithm of stochastic model is as same as the algorithm of the determined model when only one sample has been taken out. The result is the distributed function of total allowable loads, and the total allowable loads is combined with the degree of reliablity. At last we discuss the sensitive of the form of stochastic distributed function.
