摘　　要：垂盆草是中国南方喀斯特地区典型的石生耐旱药食植物,具有药用价值、经济价值和生态价值。为了掌握垂盆草的抗逆性,挖掘垂盆草的潜在价值。从耐旱、耐寒、耐高温、光照适应性和重金属与盐碱化适应性五个方面综述了垂盆草抗逆性。经分析,垂盆草抗逆性机制研究较少,今后要进一步深入研究垂盆草抗逆性的机制。垂盆草在耐旱、耐高温、耐低温上的综合表现明显,考虑石漠化缺水易干旱的环境,建议将垂盆草与苔藓结皮组合用于石漠化环境的裸岩植被生态修复,可以减轻裸岩加热效应,改善石漠化生态系统,开创新的土地资源。Sedum sarmentosum is a typical drought-tolerant edible and medicinal plants in the karst area of South China.It has Medicinal Value,economic values and ecological values.In order to grasp the stress resistanceand explore its potential value of Sedum sarmentosum Bunge.This paper reviews the stress resistance of Sedum sarmentosum Bunge,based on drought resistance,cold resistance,high temperature resistance,light adaptability,and heavy metal and salinization adaptability.After analysis,there is relatively little research on the stress resistance improvement mechanisms of Sedum sarmentosum Bunge.In the future,further in-depth research is needed on the stress resistance mechanism of Sedum sarmentosum Bunge.It is obvious that the comprehensive performance in drought resistance,high temperature,and low temperature resistance.Considering the water scarcity and drought prone environment of rocky desertification,Sedum sarmentosum and moss crust use for vegetation ecological restoration of bare rock in rocky desertification environment,it has reduce the heating effect of bare rock,improve the rocky desertification ecosystem and create new land resources.
