自然界生长着很多冬季落叶的树木,尤其在东北、西北、华北,落叶树种更多。一到冬天,这些树木的叶、花、果都没了,只剩下光秃秃的树干、枝丫,我们把树木的这种形态,称为树木冬态。依椐树木的冬态来鉴定和识别树木,比依据春夏秋形态来识别要难得多。《落叶树木冬态检索图志》(黄健秋著)依据冬天树木的树形、树皮、一二年生枝、冬芽、叶痕、叶迹、宿存的枯叶、果序等形态,来鉴定和识别树木。对林业科研、教学以及冬季林业生产都有着积极的意义,同时填补了树木冬态识别和鉴定的空白。
In nature, there are many trees with deciduous trees in winter, especially in northeast, northwest and north China. There are more deciduous trees. In winter, the leaves, flowers and fruits of these trees are gone, leaving bare tree trunks and branches. We call this form of trees the winter state of trees. According to the winter trees to identify and identify the trees, compared with the spring, summer and autumn to identify the form is much more difficult. “Deciduous tree winter state search map” (Huang Jianqiu) According to the winter tree tree shape, bark, one year branches, winter buds, leaf marks, leaves, dead leaves, fruit and other pre-order to identify and identify Trees. It has a positive meaning for forestry research, teaching and winter forestry production, at the same time, it fills the blank of identification and identification of trees in winter.
