摘要
为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,运用模糊数学方法,选用溶解氧、五日生化需氧量、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同沙水库水环境质量进行评价。3种模型计算结果均表明,同沙水库水环境受污染程度为轻污染。
As a great many of factors affect environmental quality,it is a basic task to select a rational pattern and make full use of limited information from monitors so as to describe the environmental quality objectively and provide a basis for general environment planning and preventive treatment of environment pollution.The water environmental quality of Tongsha reservoir was evaluated by applying the method of fuzzy mathematics,selecting DO,BOD5,CODCr,TP and NH3-N as evaluation factors,consulting the environmental quality standard for surface water and calculating the weight,distribution coefficients of weight and membership grade of water pollution factors.The calculating results by three patterns showed that,Tongsha reservoir was in slight pollution.
