中文摘要:20087月至201111月间先后4次调查了江西婺源森林鸟类自然保护区陆生贝类资源,共采得陆生贝类57(亚种)(3个未定种),隶属1628属,其中1种为江西新纪录种,优势种为长柱倍唇螺Diplommatina paxillus longipalatalis和细纹灰尖巴蜗牛Bradybaena ravida redfieldi。区系组成以东洋界成分为主,占种类总数的64.9%。分析11个采集点生物多样性指数结果表明,Margalef丰富度指数(dMA)范围为0.423~5.501Shannon-Wiener多样性指数(H′)范围为0.047~2.333Pielou均匀度指数(Jsw)范围为0.030~0.438。与其他自然保护区相比较,婺源森林鸟类自然保护区陆生贝类物种较丰富,与阳际峰国家级自然保护区物种相似系数较高,与甘肃白水江国家级自然保护区物种相似系数较低,陆生贝类物种多样性有明显区域性特征。
英文摘要:An investigation on the species biodiversity of terrestrial mollusks was carried out in Wuyuan Forest Birds Nature Reserve (Jiangxi province) from July 2008 to November 2011. A total of 57 species belonging to 16 families, 28 genera were collected (including 3 undefined species) and including a newly recorded species in Jiangxi province. The dominant species were Diplommatina paxillus longipalatalis and Bradybaena ravida redfieldi. Main areas of distribution analysis showed that 37 species were belonging to Oriental, accounting for 64.9% of the total diversity. The results of diversity analysis showed that the species richness indices (dMA) of 11 sampling sites were ranged from 0.423 to 5.501, species diversity indices H′ were ranged from 0.047 to 2.333, and evenness indices Jsw were ranged from 0.030 to 0.438. Compared with other nature reserves, Wuyuan Forest Birds Nature Reserve has the most diverse terrestrial molluscs which was similar with that of Yangjifeng Nature Reserve and different with Baishuijiang Nature Reserve
