　　为了探究林下鸟类调查时雾网放置场所选择的问题，2011年9月-2012年8月用网捕法对贵州省云台山林下鸟类进行调查．将雾网放置在林缘、林窗和林下3类生境中，共捕获鸟类3目12科25种231只．全年3种生境之间的鸟类数量（P＝0．033）、种类（P＝0．005）和生物量（P＝0．007）3个特征数存在显著差异，3个特征数均表现出林缘和林窗生境之间无显著差异，但林缘和林窗生境均显著高于林下生境．Shannon-Wiener指数和专有种（指仅在某种生境被捕获的鸟类）均表现为从林缘、林窗、林下依次下降的特点．对森林林下鸟类进行网捕法调查时，应该将更多的网场选择在林缘和林窗生境，而不是林下生境．

In order to explore the best sites for mist-net placement when we surveyed the forest understory birds ,a mist-net survey was conducted to understory birds at Mt .Yuntaishan of Guizhou Province from Sept .2011 to Aug .2012 . Mist-nets were placed in three habitats of canopy gap , understory ,and forest edge .A total of 231 avian individuals of 25 species ,which belonged to 12 families and 3 orders were captured . Three eigenvalues of avian number ( P= 0.033) ,species ( P=0.005) and biomass(P=0.007) were of significant difference among the 3 habitats of the whole year . No significant differences were detected between forest edge and canopy gap of the 3 eigenvalues ,but eigenvalues of forest edge and canopy gap were significant higher than those of understory's . The values of Shannon-wiener index and exclusive species (refers to the captured only in some a habitat ) were both in descending order from forest edge ,canopy gap to understory habitat .Therefore ,more sites should be considered to set in habitat of forest edge and canopy gap but not in understory habitat , when we use mist-net to survey understory birds of the forest.
