摘　　要：对江西省9市10县10个自然保护区及南昌市周边地区的陆生贝类进行了调查,并整理已记载的江西省陆生贝类,得江西省陆生贝类1纲4目20科58属170种及亚种(含6个未定种)。从种类组成上看,江西省陆生贝类以巴蜗牛科(Bradybaenidae)种类最丰富,有10属42种;环口螺科(Cyclophoridae)次之,为13属32种;树螺科(Helicinidae)、虹蛹螺科(Pupillidae)、内齿螺科(Endodontidae)、内沟蜗牛科(Strobilopsidae)和足襞蛞蝓科(Vaginulidae)均为1属1种;优势种为索形钻螺(Opeas funiculare)、灰尖巴蜗牛(Bradybaena ravida ravida)和同型巴蜗牛(Bradybaena similaris similaris)。从分布上看,江西省陆生贝类以赣东和赣北种类丰富,分别有16科33属67种和15科36属66种;赣南次之,为15科25属57种;赣中较少,为8科13属21种。对江西省不同区域物种相似性分析表明,赣东和赣西北种类组成比较相似,赣东北和赣南种类组成相似,赣中种类组成较为独特。This is an investigation of terrestrial mollusk,which was carried out in different places of Jiangxi province,including 10 nature reserves and area around Nanchang city.There are 170 species and subspecies(including 6 undefined species)which belong to 1 class,4 orders,20 families,58 genera,belong to the records and my investigation.From the point of view of composition of species,the dominant family is Bradybaenidae,with 10 genera and 42 species;the second family is Cyclophoridae,with 13 genera and 32 species;and the Helicinidae,Pupillidae,Endodontidae,Strobilopsidae and Vaginulidae with 1 genera and 1 species.The dominant species are Opeas funiculare,Bradybaena ravida ravida and Bradybaena similaris similaris.Referring to distribution,the terrestrial mollusk in east and north of Jiangxi are the most abundant,with 67 species(16 families,33 genera)and 66 species(15 families,36 genera).There are 57 species,which belong to 15 families 25 genera in south of Jiangxi.21 species,which belong to 8 families,13 genera were discovered in central of Jiangxi.Faunal similarity analysis on the different area of Jiangxi shows that species composition in east of Jiangxi is similar to the northwest,and species composition in northeast of Jiangxi is also similar to the south.Species composition in central of Jiangxi is quite unique.
