摘要:
凋落物作为草原生态系统的重要组成部分,直接参与调控生态系统微环境、种子萌发和植被更新过程. 然而目前研究主要关注凋落物自身特性对幼苗建植的影响,而凋落物管理方式对生态系统微环境和植物群落幼苗建植及其交互作用的影响却鲜见报道. 以内蒙古半干旱草地为研究对象,采用野外原位盆栽控制试验,探讨凋落物添加和去除对自然草地植物幼苗建植的影响机理. 结果显示,(1)凋落物添加和去除显著降低了植物群落幼苗建植数,分别降低22.99%和22.19%;(2)幼苗建植数与土壤含水量存在正相关关系,而幼苗建植数与近地表光合有效辐射和土壤温度呈负相关关系;(3)尽管凋落物添加通过降低光合有效辐射和土壤温度对幼苗建植有潜在的间接促进作用,但凋落物添加可能通过凋落物自身特性(机械覆盖或化感作用等)最终直接抑制幼苗建植,而凋落物去除是通过提高地表辐射和土壤温度间接抑制幼苗建植. 本研究表明,过多或过少的凋落物累积量通过改变幼苗建植所需微环境以及引起生态系统资源配置失衡,对群落幼苗建植过程产生负效应;结果可为该地区草地生态恢复与持续利用模式提供理论支持.

Abstract:
As an important component of grassland ecosystems, plant litter directly affects ecosystem microclimate, seed germination, and vegetation regeneration. However, previous research mainly focused on the effects of litter characteristics on seedling establishment, but the effects of litter management on ecosystem microclimate, plant community, seedling recruitment, and their interactions have rarely been reported. The field pot experiment was established in Inner Mongolia, China to explore the mechanism and effect of litter addition and removal on plant seedling recruitment under natural conditions. The results showed that (1) litter addition and removal significantly reduced the plant community seedling recruitment by 22.99% and 22.19%, respectively; (2) soil water content had a positive correlation with seedling recruitment, whereas photosynthetic active radiation and soil temperature had a negative correlation with seedling recruitment; (3) litter addition directly inhibited seedling recruitment by mechanical damage or allelopathy, although litter addition had an indirect potential stimulating effect on seedling recruitment by decreasing photosynthetically active radiation and soil temperature, while litter removal indirectly inhibited seedling recruitment by increasing photosynthetic active radiation and soil temperature. These results suggested that the excess or lack of litter accumulation has a negative effect on the recruitment of plant seedlings by altering the microclimate required for seedling regeneration and by causing imbalances in ecosystem resource allocation. The conclusions of this study can provide theoretical support for grassland ecological restoration and sustainable use of grassland habitats in the investigated region.
