| 摘 要： | 对南极长城站附近棕贼鸥(C.s.lonnberg)、灰贼鸥(C.maccormicki)和两者的混合配对(hybrid)的食性与考察站环境质量的相关性进行研究,结果表明,贼鸥的食物结构受站区人类废弃物的直接影响。贼鸥食性构成同时与人类活动和动物生态习性相关而起到双重信息载体作用,可作为南极环境生态评价的重要指标之一,对推动实现南极环境生态评价的量化有重要意义。

| Abstract: | Based on the sea ice digital videos and photos along the investigation route in the Second Chinese National Arctic Research Expedition (CHINARE) during July and September, 2003, collections of sea ice thickness and concentration in the area of latitude range of 74.11°N - 79.56°N and longitude range of 144.17°W - 169.95°W are finished. This paper discusses the methods of obtaining ice/snow thicknesses from ship-side videos and ice concentrations from aerial photos, and illustrates the measures should be taken in analysis and in-situ investigation processes to improve the reliability of the parameters. The methods in this paper are somewhat universal and can be used in the research of Bohai Sea and Polar Regions sea ice. |
