摘要: 两栖动物对环境变化非常敏感,可作为生物多样性监测的指示物种。为了解两栖动物种类、种群数量、生存状态以及受威胁状况,于2016-2018年的4、6和8月对广西大明山样区两栖动物多样性的时空格局进行观测。观测方法主要采用样线法(共布设10条样线),并以人工庇护所法作为补充。观测结果表明,广西大明山样区的两栖动物总计5科14属18种,其中鸭嘴竹叶蛙(Odorrana nasuta)、金秀纤树蛙(Gracixalus jinxiuensis)和红吸盘棱皮树蛙(Theloderma rhododiscus)是该保护区的新增物种。不同样线观测到的物种数或个体数略有差异,不同月份的物种丰富度和香农-威纳指数均呈显著性差异,而Pielou均匀度指数差异不显著。不同年份间的物种丰富度、香农-威纳指数和Pielou均匀度指数均无显著性差异。此外,保护区内和保护区外的物种丰富度和香农-威纳指数呈显著性差异,而Pielou均匀度指数无显著性差异。方差分析结果显示,物种丰富度、香农-威纳指数分别与海拔相关性显著,而Pielou均匀度指数与海拔没有显著相关性。物种丰富度、香农-威纳指数、Pielou均匀度指数与生境类型均无显著相关性。总体来说,大明山样区的两栖动物物种数和个体数趋于稳定,意味着其受保护状况较好。在人为干扰较弱的常绿阔叶林、草本泥泽、竹林区,两栖动物种类和数量分布比较均匀,而在低海拔山区和农田,两栖动物物种数和香农-威纳指数较高。

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.
