摘要
根据1992年8月辽河口水域营养要素的实测结果,讨论了辽河口水域溶解态无机氮（NO_3 N、NO_2 N、NH_4^+-N）、活性磷酸盐（PO_4~3 P）和活性硅酸盐（SiO_3~2 -Si）的含量、分布与变化特征。结果表明:辽河口水域溶解态无机氮含量范围为12.06～98.93μmol/L,活性磷酸盐含量范围为0.71～2.8μmol/L,活性硅酸盐含量范围为3.60～47.01μmol/L。各营养盐的含量均是淡水端高于海水端,即呈现随着水体盐度值的增大而递减的变化,并均呈现保守性行为的特征。
The contents, distribution and characteristic of inorganic nitrogen (NO3--N, NO2--N, NH4+-N), active phosphat (PO43--P) and active silicate (SiO32--Si) in dissolved state in Liaohe water are discussed based on the survey data in 1992. The results show that the ranges for dissolved inorganic nitrogen, active phosphate and active silicate in Liaohe estuary water are 12. 06～98.83μmol/dm3, 0.71～2.8μmol/dm3 and 3.60～47.01μmol/dm3, respectively. The contents of every nutrients are higher in the fresh water end than in the seawater end and show the conservative properly.
