Comparison of biodiversity among different vegetation landscape districts under tourism disturbance on Luya Mountain

The biodiversity among different vegetation landscape districts on Luya Mountain was compared by 12 indices.It was showed that:(1) With decrease of tourism disturbance,species evenness and total diversity increase gradually.As of richness,moderate disturbance makes species be abundant;however,few or serious disturbance doesn't help to increase.(2) There are clear positive correlation between richness and slope,evenness and elevation and road width,and total diversity and landscape important value.However,there are clear negative correlation between evenness,total diversity and tourism impacting index.(3) About richness indices,Patrick index and Margalef index behave preferably,but Menhinick index doesn't.Among evenness indices,Pielou index,Sheldon index and Heip index belong to one group,and Hill index and the revised Hill index belong to the other group.As of total diversity indices,Shannon-Wiener index,the N1 and the N2 of Hill index have a consistent trend.However,Simpson index is different with them because of its calculating manner and the especial ecological meaning.
