| 摘要: |
| [目的]为了促进北仑河口保护区与周边社会的可持续发展。[方法]根据2012~2014年对北仑河口保护区沿岸水域的水环境理化指标的调查,采用单因子指数法、营养水平指数法以及河口与海湾生态系统水环境健康状况评价方法评价研究区域水质的变化趋势。[结果]除无机氮外,北仑河口保护区各水质指标均符合一类或二类海水水质标准,无机氮和石油类是主要污染物。2012~2014年北仑河口保护区的营养指数分别为1.94,1.33和1.44,存在富营养化现象,且具明显的时空差异。[结论]研究期间,该海区的水环境健康指数均达到水环境健康标准,总体上处于健康状态。 |

| Abstract: |
| [Objective] In order to promote the sustainable development of national nature reserve in Guangxi Beilun estuary and the surrounding community.[Methods] Three approaches including single-factor index method,trophic level index method and water environment healthy status evaluation method of bay and estuarine ecosystem were used to evaluate the variation trend of water quality on the basis of the investigation and analysis of water physico-chemical parameters carried out in the Guangxi Beilun estuarine nature reserve during the period 2012~2014.[Results] The result showed that the water quality indexes,expect the content of inorganic nitrogen,in sampling areas were belowⅠor Ⅱ grade standard of sea water quality. The inorganic nitrogen and petroleum were the main pollutants of the sampling sites. The trophic level index of the area between 2012 and 2014 were 1.94,1.33 and 1.44 respectively,which indicated eutrophication existed there and showed significantly spatial and temporal differences.[Conclusion] During the research period,the water health indices from sampling areas met the water health standard for bay and estuarine ecosystem,which suggested the area in general is health. |
