摘要
根据我国在南极菲尔德斯半岛地区１０年的各项研究成果和南极其它相关地区的研究结果，综合分析了菲尔德斯半岛地区陆地、淡水、潮间带及浅海４个生态系统的结构和相互关系。研究结果表明，营养物质的流动使得这４个生态系统相互联系形成一个整体。在这种物质流动的过程中，动物的作用尤其关键，如海鸟（企鹅、黑背鸥等）以及海豹的繁殖、取食等活动对营养盐的搬运有利地促进和疏通了营养物质在系统间的流动。此外，物理作用（如雨水的冲刷、潮汐作用和径流的带动等）也有重要影响。
In this paper, we synthesized and analysed the structure and the interrelationship of the four ecosytems: terrestrial ecosystem, freshwater ecosystem, intertidal ecosystem, and shallow sea ecosystem in Fildes Peninsula, Antarctica, based on the research results during the past 10 years in this region, and also on the related results in other regions of Antarctica. Through our analysis, the nutrient flow integrates the four ecosystems as a whole. During the process of nutrient flow, the role of animals is very important, for example, sea birds redistribute the nutrient among the four ecosystems through their activity of breeding, feeding etc. The physical impact is also unignorable, for example, the rainfall, runoff, and tidal current bringing the nutrients from one ecosystem to another.
