Variation tendency and assessment on sea environmental quality of natural reserve zone in Dugong of Hepu in Guangxi

根据2001～2004年广西沿海渔业生态环境调查监测数据，对广西合浦儒艮国家级自然保护区水域海水环境质量变迁、综合指数地理分布及年际变化特点进行了较全面的分析研究与评价。监测结果表明儒艮保护区就控制为一类海水水质而言，海水处于受到污染的状态，Zn、Cu、Pb是保护区海水中的主要污染因子，是重点监测、控制和治理的优先污染物。

According to the monitoring data from the coast fisheries ecological environment of Guangxi during 2001 -2004 years, the analysis, research and assessment were done to the Dugong national-level nature reserve of Hepu in Guangxi sea area, including the environmental quality changes, the composite index geographic distribution and the annual border change characteristics. The monitor results showed that the sea water quality in the protection zone is at the polluted condition regarding the first kind of sea water quality standard. Zn, Cu, Pb are the main pollutants, which are the preferential pollutants to be monitored, controlled and managed especially.
