Chinese. 两栖动物是环境健康的重要指示物种（吴波等,2006）,两栖动物多样性对生态系统评价具有重要意义（Jones et al.,2010）。许多国外学者对两栖、爬行动物与森林、湿地等生态系统的恢复和利用的研究已经取得了一定成果（Roloff et al.,2011;Steen et al.,2010）,目前我国对该领域研究较少。国家林业局公布的全国第七次森林资源清查（2004―2008）结果显示,我国人工林保存面积0.62亿hm2,持续居世界首位。

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 7.961middle forest 8.324old forest 8.541）, while the biodiversity of amphibian communities reduced with forest age（young forest 1.72mature forest 1.59middle-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.
