海洋环境监测站位优化方法与应用

The Optimisation Method for Marine Environmental Monitoring Siting and Its Application

探讨了海洋环境监测站位优化步骤、方法和基本原则。指出了站位优化的4个步骤:明确监测目标;分析监测海域特征,给定抽样框架;确定站位优化方法,选择最优的监测站位;监测站位优化评估。分析表明:监测目标是进行站位优化的基础和切入点,也是选择确切的优化方法的前提;抽样框架是通过深入分析监测海域环境特征给出的;科学合理的空间数据分析方法是监测站位优化和监测评价的有效手段;优化后的站位更能最大限度的获取海洋环境信息,从而更客观的评价海域环境,为海域管理提供决策基础。

Optimisation of marine environmental monitoring siting was carried out in the following four steps: to define monitoring targets, to analyse features of the sea area to be monitored for presetting a sampling scheme, to determine the optimisation method for choosing optimal monitoring sites, and to evaluate the siting layout. It has indicated that the monitoring targets were the basis and initial point to conduct the siting optimisation as well as the prerequisite to select an adaptable optimisation method. The sampling scheme was obtained through a thorough analysis on environmental features of the sea area to be monitored, and a scientific and rational method for analysing spatial data was the effective means for the siting optimisation and environmental evaluation. Through using the optimised sites, the marine environmental information could be acquired to the maximum so as to evaluate the marine environment more objectively whilst providing a decision-making basis for the marine management.
