由于该生态系统的独特性及其动态特性，河口及其邻近水域的数值营养标准的制定非常复杂。为控制和改善长江口及邻近海域水质，以1984 ~ 2014年的水质数据为基础，采用种群分布法建立了长江口及邻近海域的数值营养标准。根据自然地理特征、水流效应和生物群落特征，将长江口及邻近海域划分为过渡带（段I）、杭州湾（段II）、河口外海岸带（段III）和舟山邻近海域（段IV）四个海分区。溶解无机氮（DIN）和磷酸盐（PO4-P）的推荐标准分别为河口I段和河口II段的1.05-1.24 mg/L和0.03-0.036 mg/L，邻近的III和IV段的约为0.2 mg/L和0.01 mg/L。溶解氧（DO）的标准相似，即6-7 mg/L。III段和IV段的化学需氧量（CODMn）标准（0.56 ~ 0.59 mg/L）远低于I段和II段的标准（1.04 ~ 1.15 mg/L）。ⅰ段和ⅱ段的总氮（TN）和总磷（TP）标准分别为1.56 ~ 1.85 mg/L和0.060 ~ 0.072 mg/L，远高于ⅲ段和ⅳ段的0.27 ~ 0.29 mg/L和0.023 ~ 0.028 mg/L。通过对营养物-藻华敏感性的验证，并与现行的海水水质标准和以往的研究进行比较，提出的标准是合理可靠的。
Developing numeric nutrient criteria for estuaries and adjacent waters has been exceedingly complex due to the uniqueness of this ecosystem and its dynamic properties. To control and improve water quality, based on data from 1984 to 2014, a population distribution approach was applied to establish the numeric nutrient criteria for the Yangtze River Estuary and adjacent waters. Based on the natural geographical characteristics, currents effects and biological community features, the Yangtze River Estuary and adjacent waters are divided into four sea subareas: the transitional zone (segment I), Hangzhou Bay (segment II), the coastal zone outside of the estuary (segment III) and Zhoushan adjacent area (segment IV). The respective recommended criteria for dissolved inorganic nitrogen (DIN) and phosphate (PO4-P) were 1.05–1.24 mg/L and 0.03–0.036 mg/L for estuary segments I and II and approximately 0.2 mg/L and 0.01 mg/L for the adjacent water segments III and IV. The dissolved oxygen (DO) criteria are similar for the four segments, i.e., 6–7 mg/L. The chemical oxygen demand (CODMn) criteria for segments III and IV (0.56–0.59 mg/L) are much lower than those for segments I and II (1.04–1.15 mg/L). The total nitrogen (TN) and total phosphorus (TP) criteria for segments I and II (1.56–1.85 mg/L and 0.060–0.072 mg/L, respectively) are much higher than those for segments III and IV (0.27–0.29 mg/L and 0.023–0.028 mg/L, respectively). The proposed criteria were reasonable and reliable based on validation using nutrient-algal bloom sensitivity and comparison with current sea water quality standards and previous studies.
