Habitat selection of Mrs. Hume Pheasant (Syrmaticus humiae) was studied respectively in fall and winter, spring and summer in Dazhongshan in Yunnan Province by the methods of used and available plots. The results of test and Bonferroni confidence interval showed that the pheasant prefer to select broadleaf evergreen forest as habitat category throughout the year, although the dominant species of tree, shrub or herb in habitat differed in seasons. The tests of differences of the factors between used and available plots indicated that there was no obvious selection for the terrain factors in the whole year except the factor of distance to the water in summer. Among all the vegetation factors that the significant different ones were listed as canopy tree coverage in spring; canopy tree density, canopy tree coverage, leaf litter coverage and herb coverage in summer; canopy tree coverage, herb coverage and liana density in autumn and winter. The results of principal component analysis of the factors in used plots revealed that the factors with large loads in principal components differed in different seasons, in other words, the key factors of habitat selection differed with seasons. One-way ANOVA and stepwise discriminant analysis validated that the features of habitat were similar between spring and autumn and winter with comparison to summer.
采用利用样地和对照样地法，分别于秋季、冬季以及春季、夏季，在云南省大中山对黑颈长尾雉（Syrmaticus humiae）的栖息地选择进行了研究。检验结果和Bonferroni置信区间表明，尽管栖息地中乔木、灌木或草本的优势物种随季节有所不同，但该雉类全年都倾向于选择常绿阔叶林作为栖息地类型。利用样地和对照样地之间各因子的差异检验表明，除夏季距水源距离这一因子外，全年对地形因子均无明显选择。在所有植被因子中，春季显著不同的是乔木郁闭度；夏季是乔木密度、乔木郁闭度、落叶覆盖度和草本覆盖度；秋季和冬季是乔木郁闭度、草本覆盖度和藤本密度。对利用样地中各因子进行主成分分析的结果显示，主成分中载荷较大的因子在不同季节有所不同，也就是说，栖息地选择的关键因子随季节而异。单因素方差分析和逐步判别分析证实，与夏季相比，春季和秋冬季节的栖息地特征相似。
