摘要
探讨灰色聚类法在水质评价中的科学性,为大庆市油田开发区湿地水环境质量评价提供了方法学参考,并为松花江中下游水环境保护提供了相关依据。首先,分析了灰色聚类法、单因子污染指数法的基本原理,然后采用相关数学方法对各监测断面水质监测数据进行评价。结果表明,除万宝泡东北侧进水口、出水口桥下的水质为Ⅱ类水质标准,龙凤湿地安肇新河为Ⅲ类水质标准,水质较好外,其余监测点水质均为Ⅴ类水质标准,水体污染严重。研究实例表明,相对于单因子污染指数法,灰色聚类法对水环境质量数据具有更高的利用能力及客观性。由于大庆市油田开发区周边有很多重要的湿地保护区,因此大庆市油田开发区湿地水质污染问题已不容忽视。
Discussing the scientific natural about using grey clustering method to evaluate water quality to provide the methodology reference for evaluation on water environment quality of wetlands in Daqing oil development zones,as well as for relevant foundation of environmental protection in midstream and downstream of the Songhuajiang River.The research explained the basic principle of grey clustering method and single factor pollution index method.The monitoring datum of water quality compared by some related math method.The results showed that Wanbao pool northwestern inlet and outlet side reached the quality assessment standard of the second-class,and the water quality of Anzhao river of Daqing Longfeng wetland reached the quality assessment standard of the third-class,and the water quality was better.The water quality of the other monitoring points was the fifth-class,and water pollution was quite serious.The research indicated that the grey clustering method about research datum was superior to that of single factor pollution index method.People should not ignore the environment protection of wetlands in Daqing oil development zones.
