Saxicolous macrolichen community characteristics in the Barluk Mountain National Nature Reserve,Xinjiang,China
摘要
Abstract
In this paper,in order to investigate the characteristics of saxicolous macrolichen communities and the relation between species distribution and environmental factors in Barluk Mountain National Nature Reserve,the two-way indicator species analysis(TWINSPAN)was used to numerical classification of communities and canonical correspondence analysis(CCA)was used to analyse the relations between the species distribution and environmental factors.The results were as follows:(1)There were 30 saxicolous macrolichens(including 2 varieties)belonging to 14 genera and 6 families distributed in this nature reserve,among which Parmeliaceae,Physciaceae and Verrucariaceae were the dominant families,having 25 species,accounting for 83.3%of total macrolichen species.(2)The saxicolous macrolichen communities were classified into five associations according to TWINSPAN analysis results,namely Association 1(Dermatocarpon moulinsii+Dermatocarpon miniatum var.imbricatum+Dermatocarpon arnoldianum),Association 2(Umbilicaria virginis+Physcia caesia),Association 3(Xanthoparmelia somloensis+Xanthoparmelia wyomingica),Association 4(Umbilicaria aprina+Phaeophyscia ciliata),Association 5(Physcia phaea+Melanelia stygia).(3)α diversity index showed that Association 3 had the highest diversity,while Association 5 had the lowest diversity;β diversity index between associations was relatively low.(4)The CCA ordination result showed that environmental factors such as altitude,slope,human disturbance degree,and rock size had a significant impact on the distribution of saxicolous macrolichen species,while air relative humidity and the acidity and pH of rocks had no significant impact on lichens;the aspect and light intensity were negatively correlated with the distribution of saxicolous macrolichens.In conclusion,the structure of the saxicolous macrolichen community in the protected area is complex,the distribution of lichen species is influenced by both natural and human factors,and there is no significant difference in saxicolous macrolichen species between different altitudes.关键词
