摘要
作者根据亲自参加中国第五次南极考察的经历,从地理环境尤其是气候对航空、航海的影响方面讨论了中国南极长城站所在地——乔治王岛菲尔德斯半岛区的战略意义。根据对地质基础、金属矿产、火山活动以及冰川侵蚀历史和地貌现象的讨论,指出该区是研究古气候、古环境、大陆漂移和冰川冰缘地貌的极好场所。最后指出,该区种类齐全、数量众多的具有南极特征的动植物和动物间奇特的食物链关系是该区成为重要的生物资源区和受南极条约保护的特别科学兴趣场所的主要原因。
Based on his own experience to take part in the fifth Chinese Antarctic expedition, this author first discussed a strategical significance of Chinese Gre- at Wall Station, Fildes Peninsula, King George Island, Antarctica according to influence of geographical environment, especially climate to aviation and navigation. Then, he discussed the geological base, metallic mine, volcanic activities, geomorphological phenomena, as well as the history of the glacial erosiop in the region, and point out that the region is an excellent place to study paleoclimate, paleoenvironment, continent drift as well as glacial and periglacial geomorphology. At last, the author indicated it is a main reason that the complete species, numerous animal and plant with Antarctic characte-ristics, as well as the animal＇s peculiar foodchain each other in the region made it to become an important biological resourceful area and a special scientific interesting place protected by Antarctica Treaty.
