【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。
[Abstract]:Environmental monitoring in coastal waters is a necessary means to grasp the environmental quality and to find out the source and scope of the pollution. Monitoring point is the basis of environmental monitoring, and the optimization of monitoring point position is a necessary means to improve the representativeness of environmental monitoring. According to the requirements of offshore environmental monitoring point layout technical specification (HJ 730 - 2014), the basic process of point optimization is carding out. After trial optimization, it is estimated that 122 national control monitoring sites will be added nationwide. Among them, 76 are selected in the original monitoring points, and 46 are set up according to the requirements of the standard. Based on the monitoring results in 2013, interpolation analysis was carried out. Before and after adjustment, the overall change of water quality was small with no subversive conclusions. At the same time, the monitoring ability of water quality in the terrigenous area was improved.

【正文快照】： 近岸海域是陆海交互地带,为人类提供了丰富的生态系统服务价值,其作为陆源污染物进入海洋的通道,也最容易受到陆源污染的影响。近年来,随着沿海开发力度加大,围海造地、污染物排放、海水养殖、石油开发、海上运输等活动给近岸海域环境带来直接或间接影响,导致近岸海域生态环境
