摘　　要：2005年12月对大亚湾大辣甲岛空气环境、声环境、地下水、陆域生态环境和西南面的近岸海域水环境进行了监测和调查,结果表明:无论1 h平均浓度范围或日平均浓度,大辣甲岛目前空气中的SO2、NO2浓度均远低于一级标准限值,环境空气质量优良;声环境较简单,基本以自然声(风和海浪)为主,环境安静;近岸海域水质监测因子:pH、DO、COD、PO4-P、D IN、石油类、总Hg、Cu、Pb、Cd、Zn等要素的浓度远低于一类海水水质标准,海水质量良好;但地下水质量较差,主要是总大肠菌群和细菌总数严重超标,不适宜直接饮用;陆域生态环境脆弱,应该加强海岛绿化造林。Based on the survey and monitoring of Dec. 2005, the environmental quality of air, sound, groundwater, land and inshore seawater in the Dalajia Island in the Daya Bay was analyzed. The results showed that the environmental quality of air, sound and inshore seawater was better, but the environment quality in groundwater was worse and the land ecosystem was frail. The SO2 and NO2 concentration in air reached the first Air Quality Standard, and the noise pollution was not found in this Island. pH, DO, COD, PO4- P, DIN, oil, Hg, Cu, Pb, Cd and Zn in the inshore waters are the first Sea Water Quality Standard, and the amount of total coliforms and total bacteria in the ground water exceeded the fifth Groundwater Quality Standard seriously and could not drink directly.
