Abstract:

In this study,8 sample plots were selected from the Daigu landform group,including the periphery plots represented by Baodugu,Menglianggu,Jiwanggu and Wuwanggu and the core plots represented by Daigu landform were Wolonggu,Daigu,Bangu and Tangwanggu.The community structure and plant species diversity of the Daigu landform were investigated.The results showed that the main vegetation types of Daigu landform were Platycladus orientalis forest,Quercus acutissima forest and Robinia pseudoacacia forest.The vegetation of Daigu landform was in the early-middle forest succession stage.The flora in the periphery area of Daigu landform is more reasonable than the core area of Daigu landform,and the vegetation at the top of Daigu landform is superior to that at the slope of Daigu landform.On the whole,the diversity indexes of tree layers,shrub layers and herb layers ranked in descending order:Daigu>Jiwanggu>Baodugu>Menglianggu>Bangu>Wolonggu>Tangwanggu>Wuwanggu.

Key words: Daigu landform, plant diversity, community structure, community succession, Baodugu, Menglianggu, Jiwanggu
