- Abstract:
-
By using plot investigation, the species diversities under secondary forest communities were studied on different slope aspects in national forest park of Tongtianhe river by Importance value, Species richness index, Species diversity index, Evenness index and Similarity coefficient index. The results showed that: (1) The highest importance value of tree layer, shrub layer and herb layer shady slope is Pinus armandi, Salix matsudana and Chloranthus japonicus. The highest importance value of tree layer, shrub layer and herb layer sunny slope is Quercusa liena, Lonicera japonica and Cacalia tsinlingensis; (2) The species diversity is significant difference between the shady slope and the sunny slope; (3) The Similarity coefficient index of shrub layer on the sunny slope was significantly less than on the shady slope. The Similarity coefficient index of herb layer on the shady slope was significantly less than on the sunny slope.
