摘要
采用模糊数学理论,有针对性地建立评价模型,对海城河上、中及下游水质进行模糊评价,分析海城河水质变化的趋势;研究中将劣Ⅴ类水质拟为Ⅵ类进行评价,突出水质评价的完整性和连续性,并与传统的综合污染指数法进行比较,体现出模糊数学理论在洁净水体评价中采用多因子贡献率来判定断面水质隶属度更为科学和客观;为环境管理、流域治理和"十二五"环境目标远景规划提供了数据信息和重要的技术支持。
Based on fuzzy mathematics theory, this study constructs a target - oriented evaluation model to conduct fuzzy evaluation on the water quality of the upper, middle and downstream of Haicheng River with a view to analyze the water quality change trends of Haicheng River. The water quality of the inferior V class is defined as the assessment of Grade VI in the research in order to highlight the integrity and continuity of water quality assessment, and to compares with traditional integrated pollution index. It is scientific and objective for the fuzzy mathematics theory to use multi - factor evaluation of the contribution rate to determine the section of water in clean water area. It provides data information and important technical support to environment management, watershed management and realization the long - range plan during the Twelfth National Five - Year Plan.
