在渤海泥质沉积区采集柱状沉积物样品，分析其黑碳含量和沉积通量，结合210 Pb年龄测定，探讨百年尺度黑碳沉积通量的时间序列变化对区域人类活动的响应。结果表明：（1）研究区黑碳含量和沉积通量分别为0.24～0.49 mg/g [平均为（0.32±0.07） mg/g]和0.026～0.053 mg/（cm2· a）[平均为（0.040±0.008） mg/（cm2· a）]，黑碳含量与我国东海内陆架等海区相当，但远低于美国港湾和瑞典大陆架等污染较严重地区；（2）黑碳通量在20世纪50年代-70年代中期和90年代初-90年代末出现两个明显的峰值，分别对应于两个阶段的生物质燃烧量和煤炭、石油等化石燃料燃烧量的急剧增加；而20世纪70年代末-80年代末较低的黑碳通量以及21世纪初黑碳通量下降的趋势则分别与黄河改道事件、我国能源利用技术提高及污染控制减排措施逐步实施等有关；（3）通过比较本文结果以及国内外其它海域和湖泊的研究资料，证明黑碳沉积记录可以作为一个良好的地球化学指标，用于评估人类活动对生态环境的影响历史。

Core sediment samples collected from the mud area of Bohai Sea (BS) were analyzed for the concentration and depositional flux of black carbon (BC) .By combining with 210 Pb radionuclide dating ,the relationship between centennial scale variation of BC depositional flux and human activities adjacent to the BS w as discussed .T he results showed that :(1) the concentration and flux of BC ranged from 0.24 to 0.49 mg/g and from 0.026 to 0.053 mg/(cm2 · a) ,with mean values of (0.32 ± 0.07) mg/g and (0.040 ± 0.008) mg/(cm2 · a) ,respectively .BC con-centration was equivalent to those in other China seas (like the East China Sea) ,but significantly lower than the heavily polluted areas ,such as America bays and Swedish continental shelf ;(2) BC flux peaked around 1950s to mid-1970s and early 1990s to late 1990s ,which each could be attributed to the sharply increased biomass burning and fossil fuels (coal and oil) combustion .However ,the lower value and the decreasing trend of BC flux occurred in the period of late 1970s to late 1980s and the initial period of the 21st century could be explained by the diversion of the Huanghe River and the utilization of clean technology for energy consumption as well as pollution control strategies ,respectively ;(3) By comparing the present results and other studies in various seas and lakes around the world ,it was confirmed that BC sedimentary record in core sediment could be used as a good geochemical indicator to reveal the influence history of anthropogenic activities on regional ecological environment .
