| 摘要: |
| [目的]对莱州湾西部海域的无机氮和磷酸盐分布情况进行分析,了解和掌握莱州湾西部海域的环境质量状况。[方法]以2011年8月该海域的监测数据为基础,分析该海域水质营养盐分布特征,并对营养化情况进行评价。[结果]莱州湾西部调查海域营养盐总体呈自西向东递减的趋势,河口附近为营养盐的高浓度区;相关性分析表明,盐度与无机氮、磷酸盐、COD呈显著负相关性(P<0.01),而COD和无机氮、磷酸盐呈显著正相关性(P<0.01);莱州湾西部调查海域无机氮污染较严重,调查海域所有调查站位的无机氮含量超《海水水质标准》(GB 3097-1997)的第一类海水水质标准,而磷酸盐含量则有37%调查站位超《海水水质标准》(GB 3097-1997)的第一类海水水质标准。[结论]莱州湾西部调查海域富营养化较严重,相关环保部门应加强监管,严格控制陆源污染。 |

| Abstract: |
| [Objective] The analysis of the distribution of inorganic nitrogen and phosphate in west sea area of Laizhou Bay was carried out to understand and grasp the environmental quality of west sea area of Laizhou Bay.[Methods] Based on the monitoring data in August 2011,we analyzed the distribution of nutrients and evaluated the water eutrophication.[Results] The nutrients concentration in west sea area of Laizhou Bay showed a decreasing trend from west to east,and near the mouth of rivers were the high concentration areas of nutrients.Inorganic nitrogen,phosphate and COD concentration showed a significant negative relationship with salinity (P<0.01),while COD showed a significant positive relationship with inorganic nitrogen and phosphate.The inorganic nitrogen pollution in west sea area of Laizhou Bay was more serious.All the inorganic nitrogen investigation stations exceeded the first water quality standard of "Sea water quality Standard" (GB 3097-1997),and 37% of the phosphate investigation stations exceeded the first water quality standard of "Sea water quality Standard" (GB 3097-1997).[Conclusion] The eutrophication in west sea area of Laizhou Bay was serious.The relevant environmental protection department should strengthen supervision,strict control of land based pollution. |
