2003年，我省海洋环境保护工作在省委、省政府领导下，在国家海洋局指导下，各级海洋环境监测单位利用多种技术手段在我省管辖的海域开展了全方位动态监测。主要内容包括水环境、海洋沉积物和海洋生物质量的全海域环境趋势性监测，同时加强了海水浴场、海洋保护区、海水增养殖区等功能区监测；首次在平潭和云霄海域设置了贝类监控区；开展了围填海、海砂开采、互花米草、陆源排污口统计监测；并在闽江、九龙江、厦门杏林工业排污口、宁德蕉城市政排污口邻近海域开展污染物入海总量监测；在全省近岸海域开展赤潮监视监测，对三都湾、闽江口、厦门近岸海域赤潮监控区实施高频率、高密度的定时定点连续监测。

In 2003, under the leadership of Fujian Provincial Committee of the Communist Party of China and Fujian Provincial People’s Government as well as the instructions of State Oceanic Administration, oceanic monitoring units of all levels carried out omnidirectional and dynamic monitoring in the sea areas in charge of Fujian Province, by using various technical means. The main contents include: water environment, marine sediment and the trend monitoring of marine life quality; at the same time, to consolidate the monitoring of the functional zones, such as seashore bathing places, oceanic reserves, marine aquafarms; to set up the seashell monitoring and controlling zones in the sea areas of both Pingtan and Yunxiao at the first time; to carry out the statistical monitoring of polder, exploiting sea sand, Spartin aallerni flora, terrestrial sewages, etc., to carry out monitoring of the total quantity of pollutants into the offshore marine areas in the Min River, the Jiulong River as well as the municipal sewages of Xinlin industry in Xiamen and Jiaocheng in Ningde; to carry out the red tide monitoring in the offshore marine areas of Fujian Province; to implement time-lapse, pointing and continuous red tide monitoring of high frequency and high intensity in the Sandu Gulf, the Min River Estuary and offshore marine areas of Xiamen.

监测结果表明：

▲ 大部分海域海水水质基本良好，符合清洁、较清洁海水水质标准，远海、近海海水水质优于近岸；与2002年相比河口、港湾等近岸海域污染范围有所扩大，主要污染物是石油类、无机氮、活性磷酸盐和汞等。

▲ 海洋沉积物环境质量总体状况良好，符合《海洋沉积物质量》标准，个别港湾有机碳、铜、镉含量超一类标准。

▲ 部分港湾海洋生物（贝类）体内的部分污染物含量仍然较高，超过一类和二类《海洋生物质量》标准的污染物有：镉、砷、铅、DDT、石油烃和粪大肠菌群。

▲ 闽江口和九龙江口污染物排放量较去年有所增加，邻近海域水环境污染仍然严重，主要污染物是化学需氧物质、无机氮、石油类和重金属等。

▲ 2003年共发生赤潮29起，其中13起造成水产养殖业直接经济损失4248万元；风暴潮灾害2次，损失7.95亿元；海浪灾害5起，死亡（含失踪）7人，直接经济损失53万元。

▲ 2003年互花米草和大米草继续蔓延。仅闽东海域侵占滩涂面积已达1.07万公顷，而且每年以5％的速度扩展。

▲ 2003年围填海15处，面积1954公顷；海砂开采点1000余处，年开采量2030万吨。对海洋环境造成一定影响。

The results show that:

▲ Most of the sea water quality was good on the whole, reaching the standard of Grade “Clean” or “Less Clean”. The open and offing sea waters quality is better than that of the offshore sea waters. Compared with the year of 2002, the polluted ranges of offshore marine areas, such as the estuaries and loughs expanded to some extent in 2003, with the main pollutants including: petroleum, inorganic nitrogen, activated phosphate, hydrargyrum and so on.

▲ The overall environmental quality of marine sediment was good and reaching the standard of < Quality Standard for Marine Sediment >, though with the concentrations of organic carbon, Cu and Cd in some loughs exceeding the standard of GradeⅠ.

▲ The concentrations in the marine lives (seashells) are still relatively high in parts of the loughs. The pollutants exceeding the standard of GradeⅠor Ⅱ of < Quality Standard forMarine Life > include: Cd, As,Pb, DDT petrolic hydrocarbon and fecal coliform bacteria.

▲ The quantity of discharged pollutants was somewhat larger than that of last year. The environmental pollution of offshore marine areas was still serious with the main pollutants such as COD, inorganic nitrogen, petroleum, heavy metal and so on.

▲ There were totally 29 cases of red tides in 2003, 13 of which caused direct economic loss of 42.48 million RMB to aquiculture. There were two storm tides with a loss of 0.795 billion and five ocean wave disasters which caused disappearance of 7 people as well as direct economic loss of 530,000 RMB.

▲ Spartin aallerni flora and Common Cordgrass (Spartina anglica CE Hubb) continued to overspread in 2003. Just in the marine areas of eastern Fujian province, they invaded and occupied an area of 10,700 hektares in the tidal-flat of Mindong sea areas, with a spreading speed of 5% annually.

▲ 15 locations of marine areas were enclosed and filled in for farmland (polder) in 2003, reaching up to an area of 1954 hektares. More than 1000 spots were employed for sea sand with an output of 20,300,000 tons every year. Both of them had some bad effects on the marine environment.
