流域动态性事故污染源最优搜索对策

Countermeasures for the Optimal Searching for the Dynamic Accidental Pollution Sources in a Drainage Basin

基于流域事故污染源最优搜索理论,在对流域内污染源的相对位置特点、各污染源排污口的规范化程度和流域受污染特征等因素分析的基础上,将流域搜索区域划分为四种类型,并针对事故污染源间歇排放的情况,提出了四类搜索区域内的事故性污染源初始概率分布函数,进而建立了相应的四类搜索区域中的动态性事故污染源探测函数。

Based on the analysis of the characteristics of the locations of pollution sources,the legitimacy of the sewage outlets and the pollution characteristics in a drainage basin,this paper classifies the search area into four types. In view of the presence of the intermittent discharge of accidental pollution sources, the pa per proposes four kinds of initial distribution functions for searching the accidental pollution sources and establishes the detection functions of dynamic accidental pollution sources correspondingly.
