| 中文摘要: |
| 2011年4~8月调查了江西井冈山自然保护区陆生贝类资源,共采得陆生贝类67种和亚种(含9个未定种),隶属4目19科31属,其中有1新种,即龙潭弯螺(Sinoennea sp.nov.)(另文报道);14种为江西省陆生贝类新纪录种;优势种为长柱倍唇螺(Diplommatina paxillus longipalatalis)、细锥倍唇螺(D. apicina)、灰尖巴蜗牛(Bradybaena ravida ravida)、双线巨蓬蛞蝓(Meghimatium bilineatum)。区系组成以东洋界成分为主,占种类总数的74.14%。阔叶林、灌木丛和农田生境陆生贝类种类较丰富,竹林和苔藓生境种类较少。根据调查数据,分别计算井冈山自然保护区5种不同生境类型中陆生贝类群落的多样性、丰富度和均匀度,结果表明,灌木丛生境陆生贝类的丰富度指数和多样性指数均最高,苔藓生境的均匀度指数最高。与邻近自然保护区比较,井冈山自然保护区陆生贝类物种较丰富,且与江西齐云山陆生贝类物种相似系数较高,与广东南岭物种相似系数较低。 |
| 英文摘要: |
| 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. |
