2011年9月于大亚湾南澳东山码头附近海域设置生态围隔,通过人为对围隔水体中N、P营养元素的加富试验,进一步分析营养盐添加对浮游细菌的丰度影响。结果表明:营养盐添加能促进生态围隔中浮游细菌丰度的增加;并且N、P同时添加于围隔中的效果要比单独添加的效果好,即能更快促进浮游细菌对营养盐的吸收和利用;浮游细菌对氨氮的吸收利用效率最高,其次是硝酸盐;N、P营养盐的添加影响生态围隔中叶绿素a以及溶解氧浓度的变化,从而间接影响浮游细菌的丰度。
2011年9月于大亞灣南澳東山碼頭附近海域設置生態圍隔,通過人為對圍隔水體中N、P營養元素的加富試驗,進一步分析營養鹽添加對浮遊細菌的豐度影響。結果錶明:營養鹽添加能促進生態圍隔中浮遊細菌豐度的增加;併且N、P同時添加于圍隔中的效果要比單獨添加的效果好,即能更快促進浮遊細菌對營養鹽的吸收和利用;浮遊細菌對氨氮的吸收利用效率最高,其次是硝痠鹽;N、P營養鹽的添加影響生態圍隔中葉綠素a以及溶解氧濃度的變化,從而間接影響浮遊細菌的豐度。

A ten-day mesocosm experiment was carried out in Nan’ao of Daya Bay in September of 2011. In total, seven mesocosms (M0~M6) were operated in the study by adding different combinations of N and P on the first day only or daily enrichment, in order to assess the biomass and richness of bacterioplankton with nutrient enrichment. The results showed that nutrient enrichment benefited the growth of bacterioplankton. N and P enriched together increased the biomass of bacterioplankton more efficiently than N and P enriched separately. Bacterioplankton was more eager to uptake ammonium than nitrate as N source. Concentration of chlorophyll a has changed due to nutrient enrichment , which resulted in the changes of bacterioplankton growth.
