摘　　要：借助网捕方法进行鸟类群落的研究表明：至少连续３ｄ的网捕才能获得鸟群落中绝大多数的物种，在网捕中应特别注意在鸟早、中、晚的３个活动高峰期间检查粘网，以及天气的影响，通过连续８ａ对北京小龙门林场小型森林鸟类群落的研究，发现其鸟群落物种数和生物量的年际变化不大，保持稳定，而群落的多样性和均匀性逐年上升。By using mist-net method to study the bird community in the forest, it was found that it was necessary to work at least 3d in order to catch the most species of the community and should make more careful checks of nets at the three peaks of daily activity rhythm of birds which in the morning, around noon and in the evening. It was also found that the number of captured bird by mist-net was affected by the weather. The successive 8a studies during summer at Xiaolongmen Forest Farm of Beijing indicated that the community species and biomass of small forest birds remained relatively stable at a not-disturbed and preserved forest farm, and the indices of species diversity and equitability increased gradually.
