【摘要】 本文就荒漠区一些植物急剧衰退的原因进行了剖析,发现除开垦过程直接导致一些物种消失外,多因资源被掠夺利用、生境被破坏或由于水资源的量和时空分布的改变所导致。注意到一些物种常因其生活周期的某一环节受胁迫而致危,故对具体物种生活周期的某一阶段或受作用的关键部位,采取适当的保护或替代措施,将能使其摆脱厄运。
【Abstract】 In recent years,some deserts are ecologically declining rapidly.The main reasons may lie in the overuses of natural resources,the destroy of desert habitats as well as the changes in amount and temporal and spatial distribution of water resources.These changes cause certain links of the life history of some desert plants to be imperiled and then become endangered.In addition,exploitation may directly cause some species to be extinct.Therefore,it is possible to conserve these desert plants by taking proper measures to protect certain critical phases of the life cycle of the endangered species
