摘要: 基于灾害的链式理论对现今土地沙漠化问题进行了分析,指出土地沙漠化无论在成因上还是在危害性的表现 结果上都呈现出复杂的链式效应,并依据灾害链式效应指出不合理耕作、开采地下水、砍伐树木、过度放牧及日益恶 化的生态环境是形成土地沙漠化灾害链的源头因素.根据孕源断链的治灾思路,提出治理沙漠化应从其孕育初期的 源头上控制灾害蔓延,切断灾害传播链,并从工程实践人手对其成效进行剖析。

关键词: 灾害链, 土地沙漠化, 孕源断链

Abstract: Land desertification at present was analyzed on the basis of the disaster chain theory.The cause of formation and the hazardness of land desertification presented a chain-form,and the source factors of disaster chain-form in land sandy desertification were revealed.And the factors includes illogical cultivating,groundwater overdraft,excessive felling,over grazing and the deteriorating ecological environment.According to chain-cutting disaster mitigation from gestation source,the mode of controlling spread of land desertification from the headstream was developed.The effects of the mode mentioned above were discussed in practice.

Key words: disaster chain, land desertification, chain-cutting disaster mitigation from gestation source
