摘  要:
针对我国内蒙古半干旱草原普遍发生的灌丛化现象,运用反映干旱和半干旱放牧系统一般动态的状态与过渡模式,建立了半干旱草原灌丛沙漠化研究的基本构架。将灌丛化作为草原沙漠化的核心过程,提出内蒙古半干旱草原灌丛化机制的假说,以及利用时空替代方法开展草原灌丛沙漠化研究的设想及其意义。

摘  要:
Sandy desertification,accompanied by the thicketization of grassland is widespread in the semiarid regions of Inner Mongolia,China.The state and transition model,a general model for the dynamics of grazing system in dry-lands,can be applied to this kind of desertification.As such,framework for the research into this process has been developed.Taking thicketization as a core component of desertification,this paper proposes a hypothesis on the mechanism of thicketization of the semiarid grasslands in Inner Mongolia.Temporal-spatial replacement is applied in order to research this kind of sandy desertification.This paper also discuses the significance of the study.
