摘要:

糙隐子草(Cleistogenes squarrosa)是内蒙古草原的优势C4植物。其对全球变化和人为干扰的响应将会影响内蒙古草原生态系统的结构、功能和服务。本文总结了糙隐子草的光合特征、水分利用特征和氮素利用特征,并阐明了这些生理生态特征对放牧、降水改变、氮添加、沙化等的响应。建议今后对糙隐子草相关生态学研究应注重于其水分利用效率对全球变化的响应及内在机制、其与共存植物的养分竞争关系、其在群落中比重的改变对草地生态系统碳循环的影响等几个方面。

Abstract:

Cleistogenes squarrosa is a dominant C4 species in the Inner Mongolia grassland. Its responses to global change and human disturbance can influence the structure, function, and service of the Inner Mongolia grassland. In this paper, we reviewed the photosynthesis, water use, and nitrogen use characteristics of this species and illustrated its physiological and ecological responses to grazing, precipitation variation, nitrogen addition, and desertification. Further ecological studies was required to examine the response of water use efficiency to global change and the underlying mechanisms, explore the nutrient relations with other plants, and the effect of the change of the biomass proportion in community on ecosystem carbon cycle.

Key words: Cleistogenes squarrosa, Grazing, Drought, Nitrogen addition, Photosynthesis, Water use
