| 摘 要： | 在滇池福保湾不同区域应用Peeper(渗析膜式)技术,分析了底泥间隙水NH4 -N、Po43--p的垂向分布特征和近表层10cm内底泥的微生物活性(FDA)、碱性磷酸酶活性(APA),并对它们之间的相互关系进行了统计分析.结果表明,NH4 -N和Po43--p浓度自上覆水向下层间隙水呈先升后降趋势,反映它们有自间隙水向上覆水扩散的潜在危害;底泥有机质(Loss-on-Ignion,LOI)、APA和FDA活性也有从表层底泥向下层逐步降低的趋势.在空问分布上,Po43--p浓度变化为河口区>湾心区>西部沿岸区>东部沿岸区,与沉积物中LOI、APA和FDA活性的大小顺序基本相同.间隙水NH4 6-N浓度与表层10cm内底泥的APA和FDA活性具有显著正相关性(α＝0.01).Po43--p浓度与底泥APA和FDA活性具有负相关性.但相关系数很低. |

| Abstract: | Peeper technique was used to sample the interstitial waters in the sediments of Fubao Bay in Lake Dianchi, and the vertical distributions of NH4+-N and PO43--P in the waters were analyzed. The activities of microbe (the activity of FDA) and alkaline phosphatase (APA) in the surface sediments were also studied. The results showed that concentrations of NH4+-N and PO43--P in the interstitial waters generally increased, then decreased, with the depth, reflecting a possible diffusion trend for these nutrients. ... |
| Keywords: | Peeper nutrients sediment activity of microbe alkaline phosphatase Lake Dianchi |
