Abstract: From June to September 2011 and April to May 2012, we conducted a preliminary investigation on the amphibian communities in the different typical plantation using the "fence with pitfall trap" in Jiangle County of Fujian Province. The result showed that: 1) Totally, 8 species of amphibians, which belong to 4 families and 7 genera, were recorded, and among them Rana limnocharis is the highest abundance; 2) The mixed forest had higher amphibian biodiversity than the pure forest and the relative-fatness indexes were 8.720 and 1.65, respectively; 3) The relative fatness of different amphibian communities increased with forest age(young forest 7.961mature forest 1.59>middle-aged forest 1.51). Therefore, in term of biodiversity conservation, we should create mixed forests and retain the coniferous trees and broad-leaved trees species in forest, to maintain the healthy survival environment and food chain for amphibians.
