中文摘要：
2007—09—05—2007-11-05和2008-09-03—2008-11-07期间，在云南省新平县哀牢山金山丫口（23°57′N，101°30′E）对影响秋季夜间网捕鸟类组成因素进行了调查。主要利用温湿度表和定性观察对各因素进行判断。其研究结果表明，地理特点是影响夜间网捕鸟类种类的主要因素；气象条件是影响夜间网捕鸟类种类和数量的重要因素。气象条件中的风向、风力、雾以及月相周期对夜间网捕鸟类数量和种类的影响极其显著（P〈0．01）。风向的影响比风力大，其中，在西南风大雾新月或者在西南风大雾残月期间，夜间网捕鸟类数量和种类最多；光也是夜间网捕鸟类的必要条件。然而，温湿度对夜间网捕鸟类数量和种类影响不显著。
英文摘要：
The influencing factors of birds captured at night were investigated by light trapping at Jinshan Yakou （23° 57′ N, 101° 30′E） of Ailao Mountain, Xinping County, Yunnan Province from 5th September to 5th November 2007 and from 3rd September to 7th November 2008. The influencing factors were analyzed by using hygrothermograph and qualitative analysis. Geography conditions had a great effect on the bird species captured at night. Weather was also an important factor influencing the number and species of birds captured at night. Statistical analysis showed that wind direction, wind force, fog and lunar phase had a significant effect on the species and number of birds captured at night （P〈0.01）. However, the effect of wind direction was more obvious than that of wind force. More birds and species were captured during nights with a southwestern wind, fog, crescent moon and old moon. In addition to light is a necessary condition for trapping. But temperature and humidity had no significant effect on the number and species of birds captured at night.
