Abstract:The forests of Populus euphratica are endemic and valuable forest resource in desert region of Gansu Province.However,for the last two or three decades,they have been destroyed seriously because people cut off the trees disorderly and denude them, and destory forests for reclaiming wasteland. Now, the remaining forests of Populus euphratica are few. The obvious declination of some Populus euphratica forests has also happened among the remaining ones because the water table comes to a lower level and result in a deterioration of the habitat. These are serious problems of the n0waday Populus euphratica forests in Gansu Province. If we do not pay special attention to such condition, the Populus euphratica forests will be extincted before long from this region.People will have to manage them properly, so that this valuable forest resource will not be extirpated from desert region of Gansu Province. Methods of proper management include to forbid strictly cutting off this tree disorderly, denuding and destroying forests for reclaiming wasteland, to irrigate and nurture the obviously degenerating Populus euphratica forests owing to the falling of ground-water table and so on. At the same time people also ought to develop actively afforestation of Populus euphratica and gradually enlarge area of this forests.
