湖北地处亚热带,位于我国第二阶梯东部边缘。在植物起源上,处于古北极和古热带两个植物区系相交接的地带范围,由于这里直接受第四纪冰川影响较小,植物区系较为繁杂、植被类型丰富。群山环抱的微域地形,成了植物的“避难所”,保存了较多的古老孑遗植物。这些幸存的植物,在系统发育过程中,经受了各种生态条件而形成的遗传特性,对目前的自然条件有较强的适应性。按照它们对生态环境的要求,进行引种栽培,不但容易成功,
Hubei is located in the subtropical zone, located on the eastern fringe of China’s second ladder. In the origin of plants, in the ancient Arctic and Paleozoic flora of the two areas of the junction of the strip, because here directly affected by the Quaternary glacier less affected flora is more complicated, rich vegetation types. The micro-area terrain surrounded by mountains has become a “shelter” of plants, preserving more ancient relict plants. These surviving plants, inherited from a variety of ecological conditions during their phylogeny, inherit their genetic traits and are well adapted to current natural conditions. According to their requirements on the ecological environment, the introduction of cultivation, not only easy to succeed,
