The species diversity, distribution and fauna geographical elements of terrestrial molluscs in Jinggangshan Nature Reserve were analyzed. 67 species and subspecies (including 9 species unidentified), belonging to 31 genera (19 families of four orders) were collected, among which Sinoennea sp. nov. is new to science and 14 species were new net to Jiangxi Province. Referring to the composition of species, the dominant species were Diplommatina paxillus longipalatalis, D.apicina, Bradybaena ravida ravida and Meghimatium bilineatum; the dominant family was Bradybaenidae, with 4 genera and 16 species, accounting for 23.88% of the total diversity. Fauna analysis showed that 43 species belong to Oriental, accounting for, 74.14% of the total diversity. The habitats of broad-leaved forest, shrub community and farmland underbrush were obviously found with relatively higher terrestrial mollusc species richness with comparison to those distributed in bamboo forest and moss. Analysis on terrestrial mollusc community characters were made based on the Shannon-wiener index, Margalef richness index and Pielou index. The species diversity richness of terrestrial mollusc community and richness was highest Shrub community,and moss had the highest species Pielou.Compared with neighboring nature reserves, Jinggangshan Nature Reserve has the most diverse terrestrial molluscs. It was found that the terrestrial molluscs in Jinggangshan Nature Reserve had higher species similarity with Qiyunshan Nature Reserve and lower similarity with Nanling Nature Reserve.
