甘肃省的胡杨林

THE POPULUS EUPHRATICA FORESTS IN GANSU PROVINCE

  • 摘要: 胡杨(Populus euphratica)林是荒漠地区特有的珍贵森林资源,甘肃省的荒漠地区也有分布,但最近几十年来由于遭到人们乱砍滥伐和毁林开荒的严重毁坏,如今所剩下的胡杨林已经不多。在所剩下的胡杨林中,不少地段又因为地下水位的下降导致生境恶化,又使得某些胡杨林产生了明显的衰退。这便是当今甘肃省胡杨林面临的严重问题。如果听之任之,让其这样发展下去,甘肃省的胡杨林势必遭到灭绝。为了使甘肃省荒漠中这项珍贵的森林资源免遭灭绝,就必须对它们进行妥善管理,包括严禁乱砍滥伐和毁林开荒,并对那些因地下水位下降而产生了明显衰退的胡杨林进行灌溉和抚育等,与此同时,还应积极进行胡杨的造林,使胡杨林的面积逐渐扩大。

     

    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.
