| 摘 要： | １９９５年冬季，测定了青岛地区四个池龄１０年以上的对虾养殖池不同层次沉积物中有机碳（ＴＯＣ）、总氮（ＴＮ）、总磷（ＴＰ）和ｐＨ并研究了其垂直分布。结果表明，沉积物中的ＴＯＣ和ＴＮ污染较底层严重，泥质虾池表层污染较泥沙质更严重。沉积物中ＴＰ为输出过程而导致缺乏，ＴＰ的受扰动层与ＴＯＣ和ＴＮ的污染层基本一致。沉积物的ｐＨ无规律性变化。

| Abstract: | In winter of 1995, the concentration of total organic carbon(TC), total nitrogen(TN), total phosphorus (TP)and pH in bottom sediments of each of four, 11-, 16-, 13-yr-old shrimp ponds in Qingdao of China were determined and the vertical distribution of them was studied. The results showed that the concentrations of TOC and TN in bottom sediment were increased with pond age, polluting depth were 20-30 cm for clay soil, were 40 cm for silt. The pollution of surface sediment is more serious than that of deep sediment, and pollution of surface sediment of clay soil is more serious than that of silt soil. The concentrations of TP in bottom sediment were decreased with pond age, so that TP was absent. The depth of disturbed layer of TP was equal to the depth of polluted layer of TOC and TN. The pH of bottom sediment does not have regular change. |
