Abstract: Amphibians are sensitive to environmental perturbations and can be used as indicator species for biodiversity monitoring. In order to understand species composition, population, survival and threatened status, the spatial and temporal patterns of amphibian diversity in Damingshan National Nature Reserve of Guangxi were observed in April, June and August of 2016, 2017 and 2018, respectively. Ten line transects supplemented with PVC pipe refugia were monitored. In total, 18 species belonging to 5 families, 14 genera were observed, among which Odorrana nasuta, Gracixalus jinxiuensis, Theloderma rhododiscus were newly recorded in the reserve. The results show that species richness and individuals observed by different transects were slightly different. There were significant differences in species richness and Shannon-Wiener index in different months, but no significant difference in Pielou evenness index. However, there were no significant differences in species richness, Shannon-Wiener index and Pielou evenness index among different years. In addition, there were significant differences in species richness and Shannon-Wiener index between inside the reserve and outside the reserve, while Pielou evenness index showed no significant difference. The results of ANOVA show that species richness and Shannon-Wiener index were significantly different with different altitudes, while Pielou evenness index had no significant difference with different altitudes. There was no significant difference in species richness, Shannon-Wiener index, Pielou evenness index with different habitats. By three consecutive years of monitoring, it could be concluded that the amphibian species richness and individuals in Daming Mountain plots tended to be stable, which means that it has been well protected. The species richness and quantity of amphibians distributed in evergreen broad-leaved forest, herbaceous mirze and bamboo forest with relatively weak human disturbance are relatively uniform, while the number of amphibian species and Shannon-Wiener index in low-altitude mountainous areas and farmland are all higher.
