摘要
本文简要介绍了南极洲的漂移演变、地理景观、气候状况和自然资源。对南极发现过程及科学考察历史亦作了简短论述。中国南极长城站位于西南极菲尔德斯半岛西南端 (58°57′52″W ,6 2°12′59″E) ,中山站则位于东南极拉斯曼丘陵的米勒半岛北端 (76°2 2′2 4″E ,6 9°2 2′2 4″S) ,两者相距 50 0 0km。作者以1991- 1995年实地考察结果为据 ,对长城站和中山站地区湖泊、溪流、雪地等淡水生态系统的理化环境、生物群落结构与功能现状进行比较研究 。
This paper briefly reviews same aspects of the Antarctica,mainly involving its evolution,geographic scenery,climate condition and nature resource.The history of scientific research in the Antarctica is also roughly retrospected.Especially,a review on its freshwater ecosystem studies is emphasized herein. The Chinese Great Wall Station (58°57′52″W,62°12′59″S) lies in southwest end of the Fildes Peninsula,West Antarctic.And the Chinese Zhongshan Station (76°22′24″E,69°22′24″S) is located at the north end of the Mirror Peninsula,Larsemann Hills,East Antarctic.The two stations are off 5000 km.In 1991-1995,field investigations were carried out,mainly including lakes,rivulets,and ice-snows in the victory of the two stations.Based on collected data,a comparative study of physico-chemical factors and organic communities in these freshwaters is made.The difference between in these waters is also analyzed.
