| 河口富营养化与流域氮、磷营养物的输入直接相关，制定河口营养物基准，可用于控制河口及其近岸海域富营养化，为环境管理的科学决策提供依据。大辽河是渤海最大的入海河流之一，河口污染较为严重；本文采用频数分布法、非参数分析法和实验室模拟压力响应关系法探讨大辽河口及近岸海域营养物基准的推导，最终得到大辽河口总氮（TN）、总磷（TP）及叶绿素a（Chl a)推荐基准值分别为1.008mg/L，0.067 mg/L和1.175mg/m3，以期为大辽河口及其近岸海域富营养化评估和营养物标准制定提供科学依据。 |

| Abstract: |
| Estuarine eutrophication is closely related to the input of nitrogen and phosphorus nutrients. Establishing estuary nutrient can provide technical support and management decisions information for avoiding eutrophication of estuaries and coastal waters, and protect sensitive and vulnerable estuaries ecosystem. The Daliaohe is one of the largest rivers entering the Bohai Sea, which estuarine pollution is serious. In order to provide a basis for the governance of the Daliaohe Estuary, this paper used the frequency distribution curve method, nonparametric analysis method, and laboratory simulated stressor-response relationship method to derive the nutrient criteria:total nitrogen (TN) and total phosphorus(TP), and the response variable criteria: chlorophyll a (Chl a) in Daliaohe estuary. The final results of the as follows :TN: 1.008 mg/L, TP: 0.067 mg/L, Chl a: 1.175 mg/m3. |
