| 中文摘要 | 安西极旱荒漠国家级自然保护区位于甘肃河西走廊，为了解该保护区鸟类群落结构的季节性变化及其原因，采用样线法于2002～2004年按季节调查了保护区鸟类的种类和数量，共见到鸟类103种。秋季种类最多，达69种；冬季最少，仅29种。夏季和春季的相似性指数最高，0.46；夏季和冬季的最低，0.31。秋季的鸟类数量最高，为37.60只/km；春季最少，9.64只/km。夏季群落多样性最高，冬季的最低。冬季优势度最高，夏季的最低。四季的优势种各不相同，优势种的数量影响各季节鸟类数量。影响安西自然保护区鸟类群落结构季节性变化的主要因素是鸟类迁徙和人类活动。 |
| 英文摘要 | The Anxi Extra-arid Desert National Nature Reserve, situated in the western of Hexi Corridor in Gansu Province, is a nature reserve for desert ecosystem. In order to find out the seasonal changes of bird communities in this reserve, line transect method was used to investigate the bird species, amount and environmental condition in different seasons during 2002 to 2004. A total of 103 species of birds were recorded in this reserve during that period. 69 species were encountered in autumn, which was the most species season throughout the whole year. However, only 29 species were met in winter. The similar index between summer and spring was the highest, up to 0.46 and at the same time, the index between summer and winter was the lowest, merely 0.31. The amount of birds in autumn was 37.60 ind./km, however, in spring was 9.64 ind./km. Community diversity was the highest in summer, and the lowest in winter. On the contrary, dominant index was the highest in winter, and the lowest in summer. The dominant species were different in each season. The amount of dominant species influenced the amount of bird in the four seasons. The main factors which led to the seasonal changes of bird communities in Anxi Extra-arid Desert National Nature Reserve were bird migration and human activities. |
