摘　　要：近岸海域环境监测是掌握其环境质量状况,摸清污染来源和影响范围的必要手段。监测点位是环境监测的基础,监测点位优化是提高环境监测代表性的必要手段。按照《近岸海域环境监测点位布设技术规范》(HJ 730—2014)的要求,梳理了点位优化工作的基本流程,经过试优化,预计在全国将增设122个国控监测点位。其中,76个在原有监测点位中选择增设,46个按照规范要求新设。利用2013年监测结果进行插值分析,调整前后水质总体变化小,未出现颠覆性结论,同时提高了对陆源影响区域水质的监控能力。Offshore environmental monitoring is an essential method to acquire the environmental quality conditions and find out the pollution source and its influence scope. Monitoring sites are the basis of environmental monitoring. Optimizing positions of the sites can improve the representativeness of environmental monitoring. According to the requirements of Technical specification for the layout of environmental monitoring spot location in offshore area of China（ HJ 730—2014）,the article hackled the basic process of monitoring sites optimization. After trial optimization,122 monitoring sites were increased nationwide,among which 76 were added from original sites and 46 were newly added according to the specification. In order to compare the difference,interpolation analysis was conducted by using monitoring result in 2013. The change of before and after the adjustment was slight. There was no subversive conclusion and the analysis precision of regional water quality for the areas affected by the land sources were improved.
