中国海洋入侵种的大海洋生态系空间分布

通过对中国海洋入侵种在大海洋生态系空间分布规律的分析,发现中国海洋入侵种的空间分布存在如下规律:(1)东海大海洋生态系海洋入侵种的种类最多,其次是南海和黄海;(2)植物性海洋入侵种种类最多,其次是动物和微生物;(3)多数海洋入侵种存在跨大海洋生态系分布的特点,较少海洋入侵种存在单一的大海洋生态系中。本文认为,保持良好的海洋生态环境是促进人类社会可持续发展的关键,以大海洋生态系为重要坐标和参照,对中国海洋入侵种空间分布规律的研究有利于我国海洋入侵种防治工作有的放矢的开展。

Spatial distribution of marine invasive species in the large marine ecosystems of China

The paper investigates the spatial distribution of marine invasive species in China from the perspective of large marine ecosystems and administrative divisions. Following results are concluded: frist, marine invasive species are primarily located in the large marine ecosystem of the East China Sea, secondarily located in the South China Sea and the Yellow Sea; second, floral marine invasive species are the most, then are the fauna and microorganisms; third, most marine invasive species are located acorss the large marine ecosystems with few marine invasive species disperse in the single ecosystem; finally, the varieties of marine invasive species increase from the high latitude to the low latitude area. Human activities are the main reasons to cause the spread of marine invasive species in China. 21st century is the Ocean's century. It is important to promote the sustainable development of human being. Taking the large marine ecosystme as the important coodinates, the research about the spatial distribution and the spread of marine invasive species in China reflects its significance and practical meanings.
