摘要

目标评估将恰巴哈尔湾海岸划分为海洋和沿海保护区的潜力地点恰巴哈尔湾，阿曼湾东北部时期2017年至2019年的两个季节研究的主要分类群大型底栖无脊椎动物方法评估基于2008年世界自然保护联盟（IUCN）生态模型类别和标准/次级标准。研究调查了生物多样性、自然性、依赖性、代表性、独特性、生产力、脆弱性和完整性等标准；研究在三个地区的三个站点的四个区域进行。在恰巴哈尔湾北部地区观察到的大型底栖无脊椎动物的丰度最高，而在科纳拉克观察到的丰度最低。发现大型底栖生物的丰度、盐度和导电率（EC）会影响大型底栖生物的群落结构；对每个区域进行了评分，将其归类为世界自然保护联盟第二类保护区。

Ecological assessment of macrobenthic communities in Chabahar Bay, the Gulf of Oman

Aim

Assessing the potential of the Chabahar Bay coasts for classification as marine and coastal protected areas.

Location

Chabahar Bay, northeast of the Gulf of Oman.

Period

Two seasons from 2017 to 2019.

Major taxa studied

Macrobenthic invertebrates.

Methods

The evaluation was based on the 2008 International Union for Conservation of Nature (IUCN) ecological model categories and criteria/sub-criteria. The study investigated criteria such as biodiversity, naturalness, dependency, representativeness, uniqueness, productivity, vulnerability, and integrity; the study was conducted at four zones of three stations within three regions.

Results

The northern region of Chabahar Bay showed significant differences in community structure compared to the other two regions. The highest abundance of macrobenthic invertebrates was observed in the northern area of Chabahar Bay, whereas the lowest abundance was observed in Konarak. Macrobenthic abundance, salinity, and electrical conductivity (EC) were found to influence the community structure of macrobenthic organisms; each region was assigned a score, categorizing it as an IUCN Category II protected area.

Main conclusions

The AMBI analysis revealed that some ecosystems in the studied regions were alarmingly disturbed, indicating the need for management attention to protect and conserve these ecosystems.

期刊介绍： Continental Shelf Research publishes articles dealing with the biological, chemical, geological and physical oceanography of the shallow marine environment, from coastal and estuarine waters out to the shelf break. The continental shelf is a critical environment within the land-ocean continuum, and many processes, functions and problems in the continental shelf are driven by terrestrial inputs transported through the rivers and estuaries to the coastal and continental shelf areas. Manuscripts that deal with these topics must make a clear link to the continental shelf. Examples of research areas include: Physical sedimentology and geomorphology Geochemistry of the coastal ocean (inorganic and organic) Marine environment and anthropogenic effects Interaction of physical dynamics with natural and manmade shoreline features Benthic, phytoplankton and zooplankton ecology Coastal water and sediment quality, and ecosystem health Benthic-pelagic coupling (physical and biogeochemical) Interactions between physical dynamics (waves, currents, mixing, etc.) and biogeochemical cycles Estuarine, coastal and shelf sea modelling and process studies.
