| 摘要: |
| [目的]探讨环境污染评价方法,以期反映广西北部湾海域污染水平的客观情况,推进海洋生态环境质量评价方法的进一步发展,为该海域的环境生态研究以及富营养化问题研究提供依据。[方法]利用水质综合污染指数和浮游植物多样性指数分别对广西北部湾海域2010年6月和2010年9月调查的数据进行污染程度评价,并讨论利用多样性指数评价的合理性。[结果]广西北部湾海域污染等级处于轻中污染至无污染之间,其中利用水质化学因子进行综合评价的结果为轻污染,利用浮游植物多样性指数进行评价的结果为轻中污染至轻污染或无污染。[结论]水质化学评价与水质生物学评价在海域污染程度上存在一定的偏差。利用浮游植物多样性指数评价海域水质污染程度,其评价标准仍有待更多的调查来验证和修正。在实际评价中不能单从指数结果就轻易下定论,应结合理化监测结果,才能得到实际结论。 |

| Abstract: |
| [Objective] Pollution evaluation method was discussed in order to reflect the objective situation of pollution level in Guangxi Beibu Gulf waters, promote the further development of quality evaluation methods for the marine environment and ecology, and provide the basis for the study on the sea environment and other pollution problems associated with eutrophication.[Methods] Two cruises were carried out, and water comprehensive pollution index and biodiversity index were used to investigate the water quality and ecological status in the Guangxi Beibu Gulf in June 2010 and March 2010.[Results] The pollution degrees of Guangxi Beibu Gulf were between moderate to non-pollution.The water comprehensive pollution index was at a light polluted status, while the phytoplankton biodiversityindex showed that the pollution degrees were between moderate to non-pollution.[Conclution] There is certain deviation in the degree of pollution in the sea waters between chemical evaluation method and diversity evaluation method of phytoplankton.The diversity index of phytoplankton in the pollution degree of water quality assessment and the evaluation standards still need more research to verify and modify, thus a simple conclusion could not be hastily educed but should be associated with physicochemical factors. |
