摘要
影响环境质量的因素很多,如何选择合理的模型并充分地利用有限的监测数据,客观地描述环境质量优劣状况,为环境整体规划及环境污染防治提供依据,是环境质量评价的基本任务。本文运用模糊数学方法,选用溶解氧、五日生物需氧量、化学需氧量、总磷、氨氮作为评价因子,参照地表水环境质量标准,通过计算污染因子权重、权重分配系数和隶属度对大燕河水环境质量进行评价。
As many factors affect the environmental quality,it is a basic task to select a rational valid pattern and make full use of limited information from monitors so as to describe the environment quality objectively and provide a basic for general environment planning and preventive treatment of environment pollution.In this paper,the water environment quality of Dayan River was evaluated properly by applying the method of fuzzy mathematics,selecting DO,BOD5,COD,TP and NH3-N as evaluation factors,consulting the standards relevant to water environment and calculating the weight,distribution coefficients of weight,and affiliated grade of water pollution factors.
