摘　　要：通过野外调查,筛选出适合桂林青狮潭水库消落带植被重建的植物物种钝叶草和硬骨草,并对这两种植物进行了室内培育,重点研究了所选植物根系的力学特性和水污染吸附特性等,结果表明:钝叶草和硬骨草在恶劣的生态环境中都具有很强的生态适应性,但钝叶草对水质的净化作用优于硬骨草,因此桂林青狮潭水库消落带植被重建的植物物种应以钝叶草为主。It selects the suitable species of Stenotaphrum helferi and Panicum repens for vegetation replanting in the fluctuating belt of Qingshi Tan Reservoir in Guilin through field survey,grows the two plants in a greenhouse and studies the characteristics of mechanics and absorption of polluted water of root system of the selected plant.The outcomes show that both species have strong adaptability in adverse circumstances, while on purification of water quality,Stenotaphrum helferi is better than Panicum repens.Thus,Stenotaphrum helferi should be selected as the main species of vegetation replanting for the fluctuating belt of Qingshi Tan Reservoir in Guilin.
