摘要
根据百法、百色断面2004年常规水质监测资料,采用单因子污染指数法对右江百色城河段的水质现状进行分析评价,并根据该河段1999年至2004年的监测资料,利用Spearman秩相关系数法进行水质变化趋势分析。结果表明,该河段水体己受污染,主要污染因子为CODMn、NH-N3和挥发酚。由此提出了污染防治的对策措施。
Based on the routine quality monitoring data of 2004 from the section of Baifa and Baise, the present situation of water quality in Baise reach of Youjiang river is evaluated by the method of single factor pollution index, and we draw a conclusion through the trend analysis of water conditions from 1999 to 2004 using Spearman＇s rank correlation coefficient method. Results show that water in the investigated area has been polluted and the main contaminative factors include CODMn, NH3 -N and volatile phenol. Some countermeasures are brought forward as well.
