象山港生态浮标自动监测数据比对结果统计与分析

Statistics and Analysis of the Monitoring Data from Autonomous Ecological Buoys in Xiangshan Bay, Zhejiang Province

生态浮标在线监测系统目前已广泛应用于污染物监测、灾害预警等多方面,监测数据的可靠性和准确性是浮标在线监测系统推广与应用的前提和基础。选取象山港海域生态浮标近3 a同时段的水质自动监测与实验室监测数据,利用SPSS软件对比对结果进行统计与分析,结果显示,浮标自动监测数据与实验室监测数据有较好的一致性,无显著的系统性偏差,大部分监测指标的正负偏差呈正态分布,可以用于对海水水质的实时监测,为决策部门及社会公众提供准确有效的海洋生态环境信息服务。

The online monitoring systems in ecological buoys have been widely used in pollutant monitoring and disaster prediction. The reliability and accuracy of monitoring data is a premise and foundation of applying this system. Study has been conducted on the water quality monitoring data from ecological buoys and laboratories in Xiangshan Bay, Zhejiang Province over the past three years, using the SPSS software for comparison and analysis.Results show that the monitoring data from ecological buoys are consistent with those from laboratories, and that no significant systematic bias exists. Most of the positive and negative deviations of monitoring indicators show a normal distribution. The system can be applied in real-time monitoring on seawater quality, providing accurate marine eco-environment information for the decision maker and the general public.
