Based on the 2014 and 2015 amphibian monitoring data of the five regions (Dayao Mountain, Mao'er Mountain, Nonggang, Darong Mountain and Liuma) of Guangxi, site occupancy analysis was done using a site occupancy model. The data show that 21 species were recorded in the Dayao Mountain, 23 in the Mao'er Mountain, 15 in Nonggang, 26 in the Darong Mountain, and 13 in Liuma. Fejervarya multistriata, Microhyla fissipes, Microhyla pulchra, Boulengerana guentheri and Polypedates megacephalus were commonly found in all the five areas. Site occupancy models were used to analyze site occupancy probabilities of the 11 commonly seen species of amphibians for estimation of their site occupancy rates and detection rates, separately. With five habitat covariates and one detection covariate introduced in, the models were used to analyze effects of environmental factors on distribution of the site occupancy rates of the amphibians, and in turn, practicability, detectivity and investigation intensity of the models were evaluated, in an attempt to modify the models and make them more extensively applicable to investigation of amphibians all over the country, and to provide information for further policy-making for scientific protection and management.
