摘要

本研究首次评估了Chabahar湾两次季风期间近海水柱浮游生物和叶绿素a和叶绿素b的物理化学特征和生物多样性的变化,以评估水质。为此,分别从Chabahar湾3.8至13.6米深度的9个和10个站点采集了27个季风前(2012年5月)的地表水样本和60个季风后(2012年12月)的表层水和深层水样本。结果表明,后季风期盐度和pH值变化较小,相对较高。季风前(2.42±0.02 mmol H+/kg)和季风后(2.44±0.01 mmol kg-1)的平均碱度水平与海洋表层水(2-2.5 mmol H+/-kg)相当。在这项研究中,共鉴定出前季风时期的浮游植物属和种,分属13个类群。结果表明,Chabahar湾内的营养物质含量较高。此外,还对水样的物理化学参数进行了调查,并与国际标准和其他海洋生态系统的数据进行了比较。结果表明,水质在规定的可接受范围内,采样区可划分为良好、稳定、健康的水生生态系统。

Assessment of Environmental Parameters in Pre- and Post-Monsoons at Chabahar Bay, Gulf of Oman
This study is the first investigation to assess the variations of physical and chemical characteristics and biodiversity of planktons in offshore water column and chlorophyll-a and b, during the two monsoons at Chabahar Bay, to evaluate the water quality. To this end, 27 surface water samples in pre-monsoon (May, 2012) and totally 60 surface and deep water samples in post-monsoon (December, 2012) were collected from 9 and 10 stations at depths between 3.8 to 13.6 m in Chabahar Bay, respectively. The results showed that water salinity and pH with low variations were relatively higher in post-monsoon. The averages of water alkalinity levels in pre- (2.42±0.02 mmol H+/kg) and post- (2.44±0.01 mmol kg-1) monsoons were comparable to that of oceanic surface water (2-2.5 mmol H+/kg). In this study, 66 phytoplankton genus and species belonging to 13 groups were identified in pre-monsoon. Results demonstrated that nutrients were at higher levels inside the Chabahar Bay. Moreover, the physicochemical parameters of water samples were investigated and compared with international standards and data from other marine ecosystems. The results indicated that the water quality falls within the stipulated range of acceptability and sampling area can be classified as a good, stable, and healthy aquatic ecosystem.
