| Abstract: | The paper expatiated Alnus nepalensis' biological and ecological characteristics and geographical distribution in detail.The biological characteristics of this species were described from the aspects of morphological characteristics,phonological characteristics and growth characteristics.In correspondence,the ecological characteristics was from the aspects of its suitable environmental condition,wood characteristics and main ecological functions;and geographical distribution from horizontal and vertical distribution.Alnus nepalensis played an important role in meliorating soil,and it was an excellent species for afforestation,promoting commercial and non-commercial forest.Therefore,the paper suggested fine species selection and origin comparative test to establish base for varieties' breeding. |
