Studies On Plant Diversity Coservation Of Forest Community In Yaoluoping National Nature Reserve

Plant diversity of forest communities was analyzed and the conversation was valued in Yaoluoping Nature Reserve by field investigation in this paper. The vascular plants were recorded more than 800 species which belong to145 families. Among these species,8 new species recorded from Anhui province and 11 exotic plants were found.Based on evaluating the threatened hierarchy of plants of forest community, the results show that 6 critically endangered species,15 endangered species,41 vulnerable species,66 lower risk species and 658 safety species can be divided into among the 786 plants.The accumulative fidelity of 17 key communities was calculated and sequenced. The order of preferential right for these communities to be protected was Com. Cyclobalanopsis glauca＞Com.Alnus trabeculosa......＞Com.Sassafras tzumu＞Com. Quercus stewardii.Shannon-Wiener index H′and Pielou index J of 17 communities is shrub layer＞herb layer＞tree layer in the same forest comunnity;H′of forest comunnities is Com.Cyclobalanopsis glauca＞Com.Alnus trabeculosa＞Com.Pinus taiwanensis,Castanea seguinii,but J of communities is Com.Castanea seguinii-Quercus glandulifera var.brevipetiolata＞Com.Cyclobalanopsis glauca＞Com.Pinus taiwanensis,Castanea seguinii＞Com.Quercus aliena var.acuteserrata-Castanea seguinii in the differient communities.
