    摘要:

    世界范围内草地生态系统的大面积退化严重影响了其生产和生态功能,因此对退化草地进行恢复成为世界范围内的持久不衰的研究热点,同时针对恢复实践效果的评估方法也在逐渐地发展和完善。在退化草地恢复进程中及时准确地评估恢复的效果有利于指导今后的恢复实践。研究概述了退化草地恢复的措施和恢复目标,对退化草地恢复的评估方法从不同的组织尺度上进行综述。研究中大多采取指示物种、植物群落的多样性和群落结构、活力-组织-恢复力(VOR)及其改良模型以及一系列数学分析方法等来评价退化草地的恢复状况。通过述评这些方法的应用和效果可以为未来的退化草地恢复实践的实施、恢复效果的科学评估以及后续的草地管理提供理论基础。

    Abstract:

    The large-scale degradation of grassland ecosystem in the world has seriously affected its production and ecological function. Therefore, the restoration of degraded grassland has become a persistent research focus in the world. Meanwhile, the evaluation methods for the practical effect of restoration are gradually developing and improving. In the process of restoration of degraded grassland, it is helpful to evaluate the effect of restoration practice timely and accurately. This review first summarizes the measures and goals of the restoration of degraded grassland, and then summarizes the evaluation methods of degraded grassland restoration from different organizational scales. In most studies, indicator species, plant community diversity and community structure, VOR and its improvement model, and a series of mathematical analysis methods were used to evaluate the restoration of degraded grassland. By reviewing the application and effects of these methods, it can provide a theoretical basis for the implementation of future degraded grassland restoration practices and the scientific evaluation of restoration effects.
