| 摘 要： | 为解决表观污染成因的问题，以苏州市区河网为主要研究对象，采集796个数据样本，对景观水体的表观污染类型进行划分界定，并通过对数据样本的统计分析，探究水体表观污染类型和水质指标之间的关系。结果表明:氧化还原电位、溶解氧、叶绿素a、高锰酸盐指数和浊度对不同污染类型的水体具有很好的区分度，可作为主要特征指标；景观水体可分为有机主导型、无机主导型、营养主导型和混合型4种表观污染类型；不同表观污染水体判别的优先次序为有机主导型、无机主导型、营养主导型、混合型。

| Abstract: | In order to solve the problem of apparent pollution causes, 796 data samples were collected from Suzhou urban river network. The types of apparent pollution of landscape water were divided and defined, and the relationship between the types of apparent pollution of water and water quality index was explored through statistical analysis of data samples. The results show that oxidation-reduction potential, dissolved oxygen, chlorophyll-a, permanganate index and turbidity have good discrimination for different types of water pollution, which can be used as the main characteristic indexes. The landscape water can be divided into four types of apparent pollution: organic-dominated type, inorganic-dominated type, nutrient-dominated type and mixed type. The order of priority discrimination for different types of surface polluted water bodies is determined, which is organic dominant type, inorganic dominant type, nutrient dominant type, mixed type. |
