为建立一套海洋沉积物监测频率的设计方法体系,作者根据中国海洋沉积物趋势性监测的特点和存在的问题,结合国内外海洋沉积物监测方案的设计理论和经验,建立了依据沉积速率确定海洋沉积物监测频率的方法和标准；基于210Pb 测年法和IDW空间插值法,绘制了中国监测海域的沉积速率空间分布图,并设计了不同空间尺度的海洋沉积物监测频率优化方案。结果显示,中国近岸区域沉积速率高于远海,河口区域沉积速率高,海湾沉积速率差异显著。其中,沉积速率高于1 cm/a的海域,监测频率为每年1次,如黄河口、长江口等河口区域；沉积速率低于1 cm/a的海域,监测周期为5 a,如渤海中部,黄海、东海远海区域等；个别沉积速率极低的海域,监测周期为10 a,如南沙海域(≤2 cm/1000 a)。监测频率高的区域主要集中在近岸沉积速率高的海域,而近海和远海沉积速率低的区域监测频率可适当降低。

According to the characteristics and the main problems of marine sediment monitoring in China, using the theory and experience of foreign and domestic marine sediment monitoring, the optimal design method and standard of marine sediment monitoring frequency were primarily established by sedimentation rate. Based on210 Pb radioactive dating and IDW interpolation, this paper put forward sedimentation rate distribution of Chinese ma-rine monitoring areas, and the optimization scheme of marine sediment monitoring frequency in different spatial scale. The results shows the deposition rate of offshore areas is higher than the open seas, and the deposition rate in Estuary is higher, it show significant differences in gulf. Monitoring frequency should be one time a year where deposition rate is higher than 1 cm/a, such as Yellow river estuary and Yangzi river estuary, and monitoring fre-quency should be one time per five year where deposition rate is lower than 1 cm/a, such as center of Bohai sea. Monitoring frequency should be one time per ten year where deposition rate is much lower than 1 cm/1000 a, such as the Nansha sea area (≤ 2 cm/1000 a). High frequency monitoring is mainly concentrated in the offshore area where there is a high sedimentation rate, and monitoring frequency can be appropriately reduced in open seas.
