| 中文摘要: |
| 为研究白洋淀网箱养鱼对北方浅水草型湖泊水质的影响,选取不同养殖年限下的网箱进行采样监测,分析白洋淀有关环境因子与养殖时间的相关性,并建立相应的回归方程。结果表明:白洋淀网箱养鱼的养殖时间与湖泊水体的环境因子DO、Chl.a显著负相关,与COD显著正相关;养殖时间与NH4+-N、NO3-N和TN显著正相关,与NO2-N无显著相关关系,与TP呈一定的正相关关系。随着养殖时间的增加,网箱养鱼加重了白洋淀浅水草型湖泊CODCr、N和P的污染负荷,在一定程度上加快了白洋淀湖泊水体的富营养化进程。 |

| To studied the water quality impaction on boreal shallow weedy lake by cage culture in Baiyang Lake，Selected the cages under different aquaculture time to Sampling and monitoring. The correlation between aquaculture time and some environmental factors ( DO，chlorophyll-a，COD，TN and TP ) was studied，and the regression equations were created. Significantly negative correlations were found between aquaculture time and dissolved oxygen，chlorophyll-a. And the significantly positive correlations were found between aquaculture time and chemical oxygen demand，ammonia nitrogen，nitrate nitrogen，total nitrogen，but not for nitrite nitrogen. However, positive correlation was found between aquaculture time and total phosphorus. With increasing aquaculture time，the results indicated that the pollution loads of chemical oxygen demand and nitrogen and phosphorus were weighted by cage culture in shallow weedy lake of Baiyang Lake，and the process of lake eutrophication was accelerated to some extentin Baiyang Lake. |
