运用主成分分析法有效地评价鉴江河水环境状况,提供科学、准确的评价。以鉴江具代表性的4个监测断面为监测对象,对7项水质理化指标进行评价,结果显示该河流的水质受工业污染较少。化州监测点在调查期综合污染均为中等,说明中上游断面受到了农业灌溉、氮磷和生活污水的影响。
The method effectively evaluate Jianjiang water environment, providing scientific and accurate evaluation of the use of the main ingredients. In view of the Jianjiang four representative monitoring section for monitoring the target of seven physical and chemical indicators of water quality evaluation results show that the water quality of the river is less affected by industrial pollution. Huazhou monitoring points in the investigation of the state of integrated pollution are moderate, indicating that the upstream section affected agricultural irrigation, nitrogen and phosphorus, and sewage.
