海南东寨港水鸟多样性的动态变化研究

Dynamic changes in waterbird diversity at Dongzhai Harbor in Hainan

  • 摘要: 为了解海南东寨港国家级自然保护区水鸟多样性的现状及其季节动态变化,以便为海南省的生物多样性保护管理提供科学依据,本研究于2021年1月—2022年12月,利用分区直数法对该保护区及周边区域的水鸟进行了为期2年的月度调查,并与该保护区以往的调查数据进行了对比分析.结果显示:本次调查共记录水鸟6目13科72种,总数量62703只次;水鸟物种多样性的季节变化趋势由多到少依次为冬季、秋季、春季、夏季;不同生境的水鸟多样性存在明显差异,其中滩涂红树林和养殖塘是研究区2种最重要的鸟类生境.对比不同历史时期的调查结果,发现东寨港水鸟种类和数量以及优势种类发生了明显变化.建议海南东寨港国家级自然保护区今后应对水鸟资源开展长期调查和监测,制定有针对性的保护管理措施,并因地制宜地开展生态修复工作.

     

    Abstract: A zonal synchronous survey was conducted from January 2021 to December 2022 at Hainan Dongzhaigang Harbor National Nature Reserve, to examine waterbird diversity, seasonal dynamic changes and trend of changes, to provide scientific and technical support for biodiversity conservation and habitat management. A total of 72 species, 13 families, 6 orders of waterbirds were recorded, out of 62703 waterbirds recorded. The seasonal changes of species diversity was winter > autumn > spring > summer. Significant differences were noted in the diversity and seasonal dynamics of waterbird in different habitats; tidal mangroves and breeding ponds were found to be the two most important habitats. Human disturbance and habitat change were important factors affecting the survival of wintering waterbirds. We suggest that conservation measures and ecological restoration strategies be formulated according to the characteristics of bird communities in different habitats, ecological restoration be carried out according to local conditions. Longer term investigations are needed.
