海南岛周围海域的水产资源和油气资源十分丰富,沿岸港湾众多,海上交通较为发达,沿海有大量的滩涂资源,是海水养殖和盐业生产的重要基地。随着沿海工业和交通的发展,尤其是莺歌海油气资源的勘探和开采,海上运输日趋繁忙,石油化学工业将蓬劲发展,这势必对海南岛沿海生态环境造成一定的危害。因此,及时了解海南岛周围海域的污染状况,为合理开发和利用海洋资源,保护海区的生态平衡提供科学依据,都具有十分重要的意义。(一)样品采集一、材料与方法
The sea area around Hainan Island is rich in aquatic resources and oil and gas resources. There are many coastal harbors, more developed maritime traffic and a large number of beach resources along the coast. It is an important base for mariculture and salt production. With the development of coastal industries and transportation, especially the exploration and exploitation of oil and gas resources in Yinggehai Sea, the maritime transportation will be increasingly busy and the petrochemical industry will develop vigorously. This will certainly cause some damage to the coastal ecological environment of Hainan Island. Therefore, keeping abreast of the pollution situation around the sea area around Hainan Island is of great significance for rational development and utilization of marine resources and protection of the ecological balance in the sea area.
