| 摘 要： | 依据2004～2010年对广西合浦廉州湾增养殖区水质连续调查监测结果,选择高锰酸盐指数（CODMn）、无机氮（DIN）、活性磷酸盐（DIP）3个代表性指标作为评价因子,采用Danniel趋势检验的Spearman秩相关系数法对该增养殖区水质状况变化趋势进行研究分析。结果表明,合浦廉州湾增养殖区水质CODMn、DIP含量保持较平稳状态,而DIN含量则呈上升趋势。削减、控制外源性氮源施入仍然是今后环境治理工作的主要任务。

| Abstract: | Based on the investigation and monitoring results of water quality in fisheries area of Lianzhou Bay,Hepu County,Guangxi during 2004-2010,the permanganate index(CODMn),the inorganic nitrogen(DIN) and the reactive phosphate(DIP) 3 representative targets were chosen as appraisal factors,change tendency of water quality condition in this reproduction area were studied and analyzed by adopting Spearman rank correlation coefficient method of Danniel tendency examination.The results showed that the CODMn and the ... |
