本文下2011年8月连续采集了青岛近岸大气气溶胶TSP（总悬浮颗粒物）样品，运用离子色谱法（IC）测定了可溶性无机氮磷组分的浓度，并估算了其干沉降通量，分析了天气过程对无机氮磷浓度的影响，讨论了大气干沉降对黄海初级生产力的影响。结果表明，夏季青岛沿海地区气溶胶颗粒物、NH4^＋-N、NorN的平均浓度分别为139．96、9．70、3．08μg／m^3，NO2^-—N和PO4^3-浓度很低，分别存0．15和1.00μg／m。以下；NH4＋-N含量约为NO3^-N的3倍，二者之和占总无机氮的99％以上。天气过程显著影响颗粒物及无机氮的浓度和组成，雾天时，颗粒物、NHjN、N（EN的浓度分别升高到晴天时的1．48、1.98和2．21倍，大风天气下分别为晴天时的1．85、2．84和4．50倍；降雨对气溶胶存在明显的清除作用，对颗粒物和无机氮的清除率分别为7．70％～32．97％和54．16％～64．49％。气象要素和气团来源、路径对气溶胶浓度和组成的影响也十分显著。颗粒态兀机氮磷的沉降通量分别为0．55和96．14μg／（m^2·d），输入黄海后呵产生94．51～138．30mg／（m^2．month）的新生产力，对总初级生产力的贡献不大，但特殊天气下大气f沉降引起的新生产力可以在短时间内迅速增加。颗粒态无机氮磷的沉降通量之比为13．7，沉降后不会使黄海磷限制的营养盐结构产生明显变化。

英文摘要：

TSP （Total Suspended Particles） samples were collected in Qingdao coastal areas during Au- gust, 2011, and the concentration of dissolved IN （NH4^＋ , NO3^-, NO2^-） and IP （PO4^3-） components were measured using IC （Ion Chromatography）. The dry deposition fluxes of nitrogen and phosphorus were estimated using concentration and dry deposition velocity. The variation of TSP, IN and IP in different weather conditions and their impacts on the primary productivity of the Yellow Sea were discussed. During the summer period, the average concentrations of TSP, NH＋-N and NO3^--N were 139.96, 9. 70 and 3. 08 μg/m^3, respectively, while NO2^--N and PO43- were less than 0.15 and 1.00μg/m^3 respectively in Qingd- ao. The ammonium and nitrate contributed up to 99% of the total IN, and the concentration of NH＋ N was about 3 times as high as that of NO3^--N. The concentration and composition of TSP and IN were influenced by different weather conditions significantly. Compared with the sunny days, the concentrations of TSP, NH4^＋-N and NO3^--N increased by 0.48,0.98 and 1.21 times respectively on the foggy days and 0. 85, 1.84 and 3. 50 times respectively under the influence of typhoon. However, the rainfall could obviously remove the particles from the atmosphere, with clearance rates being 7. 70-32. 97% and 54. 16- 64.49% for TSP and IN, respectively. In addition, the meteorological parameters, the source and the path of air mass also played important roles on the concentration variation of IN and IP. The estimated fluxes of IN and IP were respectively 0. 55 mg/（m^2.d） and 96. 14μg/（m^2.d）, which could support 94. 51-138. 30 mg/ （m^2. month） of the new production in the Yellow Sea. Though the small contribution of dry deposition of IN and IP to total primary production, the value may rise significantly within a short period in special weather conditions. The IN/IP molar ratio of dry deposition was 13.7, but the P-limition of the Yellow Sea could not be changed by their deposition because of
