白颈长尾雉栖息地的植被特征研究

Vegetation characteristics of habitats used by Elliot's pheasant.

构成白颈长尾雉阔叶林型栖息地的植被乔木层主要树种为壳斗科植物 ,灌木层植物以山茶科、禾本科和樟科等科的种类为主 ,草本层植物以蕨类、禾本科和莎草科为主 .在针阔混交林型栖息地 ,壳斗科植物仍占乔木层主要树种的相当比例 ,但针叶树种的比例明显上升 ,该类型栖息地的灌木层和草本层植物组成特征与阔叶林型栖息地相似 .在针叶林型栖息地中 ,乔木层的主要树种为马尾松、杉木、福建柏和圆柏等 ,并有较多的阔叶灌木树种构成灌木层 ,草本层中以蕨类为主 .白颈长尾雉栖息地选择的最主要影响因素是乔木层盖度 .

In habitats of the broad\|leaved forest, the dominant tree species are the species of \%Fagaceae\% in tree layer, \%Theaceae, Poaceae \%and \%Lauraceae\% in shrub layer, \%Dryopteris\% spp., \%Poaceae\% and \%Cyperaceae\% in herb layer. As for habitats of the coniferous and broad\|leaved mixed forest, \%Fagaceae\% grow as the main tree species, but the increase of coniferous tree species is recorded. The dominant species of the shrub and herb layers in the coniferous and broad\|leaved mixed forest have the same characteristics as in the broad\|leaved forest. In habitats of the coniferous forest, the dominant tree species are \%Pinus massoniana, Cunninghamia lanceolata, Fokienia hodginsii\% and \%Sabina chinensis\%. The shrub layer is composed of many species of broad\|leaved trees, and the shrub layer--of \%Dryopteris\% spp. The tree layer cover is the key factor for \%Elliot's pheasants\% to select their habitat.
