| 摘 要： | 根据2005—2010年对南四湖水体水质监控资料，对N、P的分布现状、季节变化特征、NIP比值、网箱区与网围区N、P分布特征进行比较，分析与评价了湖区渔业养殖对水体TN、TP的影响．结果表明：南四湖水域营养盐多数时间为TN、TP共同限制水体，TN、TP含量有明显的季节变化，5—9月呈上升趋势，10月份明显降低．非养殖区TN、TP含量略大于养殖区，网箱养殖对N、P的影响大于网围养殖．通过水质标识指数法评价南四湖水质为V-劣V类水，明显低于功能目标要求．

| Abstract: | This study was carried out to analyse and evaluate the influence of aquatic TN and TP in fishery of lake water,according to the water monitoring data of Nansi Lake from 2005 to 2010, by comparing of the N and P distribution present situation, the seasonal variation characteristics, N/P ratio, cage culture and enclosure aquaculture area N and P distribution characteristics. The results indicated that the water body of Nansi Lake nutrition was TN and TP limited water most of the time. The content of TN and TP had obviously seasonal variation. It showed ascendant trend from May to September and obvious downtrend in October. The TN and TP contents of the non - breeding area were slightly higher than those of the culture area. The influence of the cage culture on N and P was greater than the enclosure culture. The water quality of Nansi Lake was V or inferior V by single factor water quality identification index, which is lower than the aim of the function requirements. |
