摘　　要：2007年11月～2008年5月调查了江西阳际峰自然保护区陆生贝类资源,共采得陆生贝类47种(含2个未定种),隶属13科27属,其中16种为江西省陆生贝类新纪录种。区系分析表明,该保护区陆生贝类以东洋界成分为主,占种类总数的63.83%。其优势种为墙草真管螺和同型巴蜗牛。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0～6.2345;Shannon-Wiener多样性指数(H′)范围为0～3.5676;Pielou均匀度指数(J)范围为0～1.3610。环境越复杂,种类组成越丰富;物种分布越均匀的地区,陆生贝类多样性指数就越高。An investigation on the species biodiversity of terrestrial mollusks of Yangjifeng Nature Reserve in Jiangxi prov- ince was carried out from November 2007 to May 2008. 47 species belonging to 13 families, 27 genera were collected （ including 2 undefined species）. Sixteen of the 47 species were newly recorded species in Jiangxi province. The results of fau- nal analysis showed thai the main faunal element were Oriental realm species which accounted for 63.83% of the total spe- cies. The dominant species of this area were Euphaedusa parietaria （ Schmacker ＆ Boettger） and Bradybaena similaris simi- laris （Ferussac）. The results of diversity analysis showed lbat the species richness indices d~ of 11 sampling sites ranged from 0 to 6. 2345 ; species diversity indices H＇ ranged from 0 to 3. 5676; and evenness indices Jsw ranged from 0 to 1. 3610.
