Abstract:

Field survey on bird community was conducted by line transect method in Dazhangshan Mountain,Jiangxi Province from June,2009 to August,2010.Species diversity,evenness,dominance and the comparability index between different habitat communities were analyzed.Birds of 87 species were recorded in the zone,which belong to 13 orders,31 families.Among them 45 species are residents including 21 species of summer migrants,7 species of winter migrants and 5 species of migrant birds.Among them,6 species are listed as Rank Ⅱ species of the National protected species,22 species are listed as protected animals at provincial level.Of the total species,half of species distribute in the Oriental realm,282% occur species in the Palaearitic realm and 218% species in both.〖WTBX〗Pycnonotus sinensis and Lonchura striata were dominant speices in summer.In six typical communities,both ShannonWeiner index and Simpson index were ranked by broadleaved forest>farmland and village>coniferousbroad leaved mixted forest>ghyllvalley>shrubgrassland>coniferous forest of bamboo grove.Pielou index was ranked by coniferousbroad mixted leaved forest>ghyllvalley>broadleaved forest>farmland and village>shrubgrassland>coniferous forest of bamboo grove.Sorenson index between broadleaved forestsconiferousbroad mixted forest leaved (S=048) was highest.Results indicated a new concern in local forest managements and bird conservation
