松花江流域省界缓冲区典型断面水质状况分析研究

以松花江流域省界缓冲区典型监测断面数据(2007-2014年)为基础,利用内梅罗污染指数法对流域水质情况进行综合评价,结合年变异系数和相关系数探究水质年际、年内变化趋势.根据监测断面数量和Ⅲ类及以上水比例变化情况分析省界缓冲区水质状况.根据水质特点确定主要超标项目,结合单因子评价法分析主要监测断面的水质类型、年际变化情况,并对监测指标相关性和超标率进行分析.根据上述分析结果,提出针对松花江省界缓冲区的监管对策及建议.

Analysis of Water Quality in Typical Monitor Section on Provincial Boundary Buffer Area of Songhua River Basin

Taking basin monitoring data of the typical monitoring section on provincial boundary buffer area of Songhua river from 2007-2014 as the foundation of data, this paper evaluates the water quality by using Nemerow pollution index.Variation co-efficient and correlation coefficient were used to explore the inter-annual variation of water quality and analyze the water quality from the number of monitoring sections and the ratio of Ⅲ category and above .Major pollution projects were determined according the characteristics of the provincial boundary buffer area. The study analyzes the type and the inter-annual variations of the moni-tored water with single factor evaluation method and analyze the relevance and exceeding standard rate of monitoring indicators . Based on the above consequence, it proposes appropriate regulatory measures and suggestions to the Songhua River provincial boundary buffer area regulatory.
