| 中文摘要: |
| 2009年10月至2010年10月,对辽宁省大连市庄河地区3口刺参(Stichopus japonicus)养殖池塘的氮(N)、磷(P)、硅(Si)营养盐进行了初步调查。结果表明,3口池塘全年平均总溶解无机氮(DIN)浓度为17.36μmol/L,硝酸盐(NO-3-N)与DIN的变化趋势基本一致,年均值为12.61μmol/L,亚硝酸盐(NO-2-N)年均值为1.61μmol/L,氨氮(NH+4-N)年均值为3.14μmol/L,磷酸盐(PO-34-P)与硅酸盐(SiO-23-Si)年均值分别为0.40μmol/L和19.76μmol/L。氮磷比(N/P)年均值为61.41,其中冬季和春季明显高于其它季节。硅氮比(Si/N)年均值为2.08,冬季和春季均小于1,其他季节均大于1;硅磷比(Si/P)年均值为50.12。3口刺参池塘各项指标差异不大,变化趋势基本一致。 |

| The nutrients ( N，P，Si )of Stichopus japonicus pond were investigated from Oct. 2009 to Oct. 2010 in Zhuanghe Liaoning Province. The results showed that the average concentration of DIN in the three ponds was 17.36ūmol/L; The change of nitrate nitrogen was the same as DIN while the mean value was 12. 61 ūmol/L; The average nitritenitrogen was1.61ūmo1/L; The average ammonia-nitrogen o was 3.14umol/L; The mean values of phosphate and silicate were 0.40umol/L ,19.76umol/L ,respectively. The average(N/P) was 61 .41，the data of winter and spring was higher than the other seasons; The average(Si/N)was 2.08，the(Si/ N)of winter and spring was less than 1 , while more than 1 in the other seasons; The average(Si/P) was 50. 12. The change of data consistent in the three ponds.
