| 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.

| Abstract: | 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 replacement is app cance of the study mechanism of thicketization of the semiarid grasslands in Inner Mongolia. Temporal-spatial lied in order to research this kind of sandy desertification. This paper also discuses the significance of the study. |
