广西涠洲岛珊瑚礁海域水质环境变化研究与评价

Analysis and Appraisal of Seawater Quality in Coral Reef water,Weizhou Island,Guangxi

文章根据2013—2016年广西涠洲岛珊瑚礁海域水质实际调查情况,应用单因子污染指数评价法、富营养化指数法和有机污染指数法,对近年来涠洲岛珊瑚礁海域水质环境变化进行综合分析和评价。2013—2016年,广西涠洲岛珊瑚礁海域水质大部分符合国家第一类海水水质标准,满足珊瑚礁的正常生长要求,但悬浮物含量持续偏高,对珊瑚礁造成一定影响。涠洲岛海域水体虽未出现显著的污染,根据历史数据分析,人为排污已在一定程度上影响珊瑚礁的生长,持续的监测有助于及时发现水质环境质量的变化。

Based on the data obtained from seawater in coral reef of Weizhou Island,Guangxi from2013 to 2016,seawater quality was analyzed and evaluated by means of the single-factor pollution index,the eutrophication index,organic pollution index.The results showed that most of the seawater quality in line with the national first class of seawater standards in Weizhou Island,Guangxi from 2013 to 2016,which met the normal growth requirements of coral reefs.Except for the continuous high value of suspended matter,which needs to be noticed on the impact of coral reef.There was no significant pollution of seawater in coral reef of Weizhou Island,but the combination of historical data showed that human pollution had a certain extent impact on the growth of coral reef.Continuous monitoring is helpful to detect changes in seawater quality.
