    Root system is the most important bridge connecting the above-ground and underground ecosystems, and plays an im portant role in the energy flow and material circulation of ecosystems. Heterogeneous environment caused by intense water-salt exchange in coastal wetlands is one of the most important factors affecting the structure and function of plant roots. This paper reviewed the re search progress of water and salt stress on wetland plant root system in the past few years, previous studies focused on the response mechanism of plant roots under constant stress simulation, however, the heterogeneous habitat characteristics in nature was ignored. The research on plant adaptation to habitat heterogeneity is mostly focused on the acquisition of resources by roots, but the research on root response mechanism in heterogeneous stress habitats is still scarce. The coastal wetlands in the Yellow River Delta have the characteris tics of river-sea interaction, land-sea transition and newly-formed. It is natural ideal experimental site for studying the root response mechanism under the condition of habitat heterogeneity. However, there are few studies on plant roots in the coastal wetlands of the Yellow River Delta. Based on the research progress of plant root of coastal wetlands in the world, three aspects of future research on root ecology of coastal wetlands in the Yellow River Delta were suggested: 1) Effects of time heterogeneity of water and salt on vegetation of coastal wetlands; 2) the relationship of clonal integration of root system and community and ecosystem under heterogeneous habitat; 3) root response of wetland clonal plants to climate changes.</p

    由于气候变化和人类活动的影响,世界许多海区尤其是近岸海区发生了不同程度的低氧现象,导致海洋动物大量死亡,对海洋生态系统产生了不同程度的影响。为明确烟台牟平海洋牧场低氧对大型底栖动物的生态效应,我们于2016年夏季(6月、8月、9月共3个航次)在该海域进行现场调查,分析低氧对大型底栖动物群落时空变化的影响。结果表明:牟平海洋牧场8月低氧事件发生时,大型底栖动物群落的优势种为短叶索沙蚕(Lumbrinereis latreilli)、不倒翁虫(Sternaspis scutata)和内肋蛤(Endopleura lubrica)。低氧在一定程度上改变了大型底栖动物的群落结构,表现为物种组成和优势种变化上。例如,耐受低氧的机会种数量增加,如短叶索沙蚕;敏感种数量减少,如微小海螂(Leptomya minuta)、长吻沙蚕(Glycera chirori)、大蝼蛄虾(Upogebia major)、极地蚤钩虾(Pontocrates altamarimus)、塞切尔泥钩虾(Eriopisella sechellensis)等。同时,低氧也导致了物种多样性的降低,但丰度和生物量受其影响不明显,这主要是由于机会种短叶索沙蚕丰度和生物量的剧增所致。大型底栖动物不同物种耐受低氧的阈值不同。例如,短叶索沙蚕在溶解氧(DO)<1.0 mg/L受影响最大,在DO=2.0 mg/L时受到的影响不明显,而其他敏感种如微小海螂、大蝼蛄虾、极地蚤钩虾、塞切尔泥钩虾等在DO<2.5 mg/L时,已表现出明显的不适。低氧事件之后,大型底栖动物群落得到一定程度的恢复,其恢复程度和需要的时间长短与低氧发生的程度有关
