- Abstract:
- The ecological response of subalpine meadow population to tourism disturbance on subalpine meadow on the south top of Wutai Mountain is studied by the index of niche breadth in the paper.It shows that: (1) the niche breadth of Festuca rubra，Pocygonaceae viviparum and Kobresia bellardii is more，and they are dominant species in the community.With the distance increase，tourism disturbance is weakening，species number is adding up，and their niche breadth is largening，which indicates that population is confined to the surroundings by the disturbance.The relative dominance of Festuca rubra decreases，and that of Kobresia bellardii increases.(2)Kobresia bellardii,Potentilla nivea,Anphalis henecockii,Vicia unijuga,Dendranthema chanetii and Oxytropis caerulea belong to the increasing type,Polygonum aviculare belong to the decreasing type,and Sanguisorba officim is one of the fluctuating type.
