2003～2010年铁山港湾营养盐的变化特征
Variation Characteristics of Nutrient Concentrations in the Tieshangang Bay
摘要
Abstract
Based on the data obtained from twenty-two cruises in the last eight years from 2003 to 2010 , long-term variations of nitrate,nitrite,ammonia,inorganic nitrogen,reactive phosphate and silicate in the Tieshangang bay were studied. The result showed,that concentration of inorganic nitrogen ranged from 0. 21 to 47. 86 μmol/L, reactive silicate ranged from 0. 01 to 0. 71 μmol/L and phosphate ranged from 4. 29 to 124. 29 μmol/L,respectively. Spatial distribution of nutrient concentration among stations and the changes in different seasons were variable during the last eight years,and consistent changes in nutrient distribution and seasonal variation were not observed among those years in the Tieshangang bay. Long-term variation of nutrition concentration showed increasing trend from 2003 to 2008 and then decreased, which was a little different from that in the Qinzhou bay. Long-term variations of nutrition in the Tieshangang bay were mainly influenced by river run-off,land pollution and nutrient regeneration.关键词
