Baotou Section Of The Yellow River Water Quality Change And Economic Development Grey Correlation Analysis

This paper is mainly research for the water quality monitoring data of Baotou section of the Yellow River from2001to201O.We choose chemical oxygen demands five day biochemical oxygen demand、ammonia-nitrogen、potassium permanganate index、fluoride、petroleum、sulfate,the7monitoring project, as the evaluation index and use the water quality comprehensive pollution index method to analysis and calculate the water quality data. The calculation result shows that from2001to2010, during these10years the three main pollutants of Baotou section of the Yellow River is potassium permanganate index、ammonia nitrogen and chemical oxygen demand (cod).The most serious pollution in three parts of Baotou section of the Yellow River is Dengkou exit. Comprehensive pollution index showed a downward trend year by year.Select the2001-2010year’s statistical data to reflect the city’s economic development. Main investigation of the scale and level of economic activity> industrial structure、environmental management and protection input and urbanization process. Specific indicators for GDP、Per capita GDP、Industrial proportion、the proportion of the third industry、Industrial wastewater treatment projects into the forehead、Drainage pipe length、The proportion of the total population of the urban population and Life water consumption. We use this eight projects as evaluation index. We use Deng’s model as our Calculation model, and distinguish coefficient0.5,each by2001-2010potassium permanganate index monitoring data、Ammonia nitrogen monitoring data and Chemical oxygen demand (cod) monitoring data as a reference sequence. The2001-2010year’s statistical data has constituted comparison sequence, calculated each correlation and get the main influence factors. As a whole, Industrial structure and Urbanization process are the most important influence factors of the three major pollutants.Based on this, strengthen economic and social developments adjust industrial layout.To actively respond to the urbanization process and the prevention and control of pollution suggestions.
