象山港海域海洋环境监测站位优化及验证分析

根据象山港海域2011年专项研究项目监测站,结合赤潮监控区站、趋势性监测站等50个测站,运用普通克立金方差分析法,对研究区现有海洋环境监测站位进行分析,优化后获得38个测站。再采用统计学中的T检验方法,对站位优化前后象山港海域环境监测数据进行方差分析,经统计检验,2组数据之间无显著性差异,说明优化后的38个监测站位所表征的监测信息量与现有50个监测站位的信息量等效,可作为今后的常规监测站位。

Optimal design of marine environmental monitoring sites in Xiangshangang Bay and verification analysis

According to the special research project of 2011, combined with the red tide and trend monitoring, the existing 50 monitoring stations were optimized for the best 38 monitoring sites by using ordinary Kriging variance analysis method. Then the variance analysis was carried out to test the original and the optimized monitoring data by using the T test method. There was no significant difference between the 2 groups of data. The result show that the amounts of information get from the optimized stations are equivalent to the original ones. So the optimized stations can be used as regular monitoring stations in the future.
