摘要:
干旱区水源不足是制约荒漠植被发展的原因。当植被衰退，径流侵蚀作用将加剧，降水仍存留于原地的量将更少，更难以维持植物的生存；而范围较广的集水地形即因淤积、蒸发作用而导致盐渍化，虽水量充裕亦难助植物繁生，有限降水的水源，反成加剧荒漠化过程的动因。研究表明：利用微集水以重建荒漠植被是化解此恶性循环的关键。
Abstract:
In arid area,insufficient water restricts the development of desert vegetation.But after the vegetation declining,erosion of the runoff will be aggravated.A little water remainded in the same place can not preserve the vegetation living.Though there has enough water resource,the runoff collecting area also can not sustain the lush growth of vegetation,because of its siltation,evaporation and salinization.So the limited precipitation may intensify desertification.The study shows that the vegetation reconstruction is the key to dispel the vicious circle.According to the data on the spot,a series of countermeasures are put forward.
