Investigation and Potential Evaluation of the Natural Restoration Ability of Trees,Shrubs,and Herbs in the Burned Areas of Tianzhu Area
The germination rate and germination index of different trees,shrubs,and perennial herba-ceous plants in burned areas were investigated.The results showed that the overall post disaster regenera-tion potential of the trees was the lowest,with germination rates ranging from 0 to 28.36％and germina-tion indices ranging from 0 to 0.28.Among the trees,poplar had the highest germination rates and ger-mination indices,at 28.36％and 0.28 respectively.The overall post disaster regeneration potential of shrubs is moderate,with a germination rate of 36.21～60.18％and a germination index of 0.48～0.64.Among the shrubs,Qinghai Rhododendron has the highest germination rate and germination index,with 60.18％and 0.64 respectively.The overall post disaster regeneration potential of perennial herbs is the highest,with a germination rate of 96.02～100％and a germination index of 0.84～0.98.Among pe-rennial herbs,Gansu Iris has the highest germination rate and germination index,with 100％and 0.98,respectively.
