摘　　要：2010年11—12月,在广西九万山国家级自然保护区对白眉山鹧鸪冬季觅食地选择进行研究。发现觅食点34个,设置利用样方和对照样方各25个,测量并分析19个有关参数。结果显示,白眉山鹧鸪对阔叶林、针阔混交林、阔叶摆竹混交林和摆竹林表现为随机利用,对毛竹林和杉木林表现为避开选择;其偏向选择面朝东南方向的山坡,觅食地坡度在20～44°之间,觅食地摆竹灌丛密度和摆竹灌丛盖度、草本密度和草本盖度都显著低于对照样方,落叶盖度显著高于对照样方。逐步判别分析结果表明,落叶盖度、坡度和摆竹灌丛盖度是区分冬季觅食地和对照样方的主要参数,判别准确率达86.0%。白眉山鹧鸪冬季对觅食地的选择与食物资源和躲避危险有关。因此,建议在保护白眉山鹧鸪时应着重关注这两个因素。The winter feeding sites of White-browed Hill Partridge（Arborophila gingica） was investigated in Jiuwanshan National Nature Reserve in Guangxi from November to December 2010.With the 34 found feeding sites,the used sites（n=25） were compared with the control sites（n=25）,and 19 parameters were measured at each site.The results showed that White-browed Hill Partridge randomly use broadleaved forest,mixed coniferous-broadleaved forest,mixed broadleaved-bai bamboo（Indosasa shibataeoides） forest and bai bamboo forest,while they rarely occurred in mao bamboo（Phyllostachys edulis） forest and China fir（Cunninghamia lanceolata） forest.The birds prefer to select the southeast-facing slops of 20 ？ 44 degrees,with smaller bai bamboo-shrub and grass density,lower bai bamboo-shrub and grass coverage,and greater shatter coverage.We found that the main selection factors at the used and control feeding sites,using the Step DA,were the shatter coverage,slope,and bai bamboo-shrub coverage.The veracity to distinguish was 86.0%.The feeding sites selection of White-browed Hill Partridge is associate with food resources and safety index,thus,we suggest that the protection should focus on these two aspects.
