| 中文摘要: |
| 2008年至2011年在丰水期和枯水期对鄱阳湖区都昌县水域蚌类养殖水体进行调查，探究理化环境参数的变化特征，运用SPSS16.0进行环境因子与营养盐的相关性分析。结果表明，水温、pH和DO随季节性变化明显，丰水期和枯水期平均水温为29.4℃和8.6℃，pH为7.43、7.22，DO均值为7.11mg/L和10.84mg/L，符合国家渔业水质标准；环境因子的年际变化趋势不一，水温升高趋势明显，DO经历缓慢下降的过程，pH有升高趋势；环境因子之间相关性不明显，营养盐与环境因子相关性中，TP与水温极显著负相关，相关系数最大（r=-0.7102）。 |

| In wet and dry seasons between 2008 and 2011, surveys were conducted in typical mussel aquaculture waters in Duchang Waters of Poyang Lake. Characteristics of physicochemical environment parameters in major mussel culture areas were revealed by analyzing correlations between environmental factors and content of nurients using SPSS 16.0 sofeware.The results showed that water temperatures , pH and DO significantly varied in different seasons. In wet seasons, the average water temperature, values of pH and DO were 29.4℃,7.43 and 7.11mg/L, respectively. While in the dry seasons, they were 8.6℃,7.22 and 10.84mg/L，respectively. The water quality met the national fisheries water quality standards. Environmental factors varied between years, the water temperature increased significantly, DO experienced a process of falling slowly and pH tended to increase.There was no obvious correlation among environmental factors, but the correlation of some nutrients and environmental factors were obvious, for example, the water temperature and the TP were in a strong negative correlation, with the maximum correlation coefficient r=-0.7102. |
