【摘要】：河口营养盐基准制定过程中,基准值的确定以参照状态为基础。在选择参考点时,可以采用两种途径:一是历史数据分析,二是实际调查数据分析。本文以辽河口为例,主要应用频数统计分析法建立了辽河口营养物总磷(TP)、总氮(TN)、活性磷酸盐(PO~(3-)_4)、溶解无机氮(DIN)及响应指标叶绿素a(Chl-a)、溶解氧(DO)的参照状态。辽河口营养物总氮、总磷、溶解无机氮、活性磷酸盐的推荐基准值为1.11、0.037、0.77和0.004 7mg/L;响应指标叶绿素a、溶解氧的推荐基准值为0.011、5.73mg/L。研究结果旨在为中国开展系统的水质基准、标准的研究提供理论和方法借鉴。
[Abstract]:In the course of establishing the nutrient standard of estuary, the determination of the reference value is based on the reference state. In selecting the reference point, two ways can be adopted: one is historical data analysis, the other is actual investigation data analysis. This paper takes Liaohe Estuary as an example. The reference states of total phosphorus (TP), total nitrogen (TNN), active phosphate (POP) (3-D), dissolved inorganic nitrogen (DIN3) and the response index (chlorophyll a Chl-a, dissolved oxygen) in Liaohe Estuary have been established by means of frequency statistical analysis, the total nitrogen, total phosphorus and dissolved inorganic nitrogen in Liaohe Estuary have been established, and the total nitrogen, total phosphorus and dissolved inorganic nitrogen in Liaohe Estuary have been established by means of frequency statistical analysis. The recommended standard values of active phosphate were 1.11 ~ 0.037 mg / L and 0.004 mg / L, respectively, and that of chlorophyll a and dissolved oxygen were 0.011 ~ 5.73 mg 路L ~ (-1) 路L ~ (-1) respectively. The results of the study were intended to provide a theoretical and methodological reference for the study of systematic water quality standards in China.
