| 摘 要： | 青岛地区大气沉降物中溶解态碳水化合物平均浓度为３．３ｍｇ／Ｌ，明显高于河水与海水。１９９１年６－１２月ＤＣＨＯ通过大气向海洋输送的通量为８４０．９ｍｇ／ｍ＾２，ＤＣＨＯ浓度与降雨量呈岁相关，且ＤＣＨＯ浓度及沉降量的季节变化明显。酸雨使得ＤＣＨＯ浓度升高，改变了碳水化合物在液固相间的分配。

| Abstract: | The average concentration of dissolved carbohydrates (DCHO) in atmospheric deposition at Qingdao was 3. 3 mg/L, and particulate carbohydrate (PCHO) ranged from 1. 7 to 18. 1 mg/L, which are higher than those in the seawater and river water. The flux of DCHO is to the NW. Yellow Sea via atmosphere is estimated ca. 840. 9 mg/m2 from June, 1991 to December, 1991. Negative correlation between DCHO and rain fall (mm) was observed during our study, acid deposition corresponds to the higher DCHO level. Seasonal variations of both DCHO ed PCHO were observed. Ratio of DCHO and PCHO (Kd) averages 1. 5. It has: been recognized that the Kd falls with increasing of rain pH. |
