【摘要】 在桂西山地南缘右江上游农区,投放7654个铗夜,捕获小兽627号,捕获率8.19％。经鉴定共有16个物种,分隶于2目3科。其中鼠科13种占捕获物种的81.25％,小家鼠属(Mus)3种占18.75％;竹鼠科1种;鼩鼱科2种。小兽区系呈现华中区——西部山地高原和滇南山地亚区的典型特征。根据调查样区的自然环境特征可划分成7类生态小区,以此为基础则可划分成相应的7类小兽群落,即:小平原水稻、蔬菜作物生态小区——黄毛鼠+小家鼠+黄胸鼠群落(A);河岸和阶地水稻、甘蔗生态小区——小家鼠+黄毛鼠+臭鼩群落(B);山间谷地水稻生态小区——黄毛鼠群落(C);山麓坡地玉米、水稻和薯类生态小区——黄毛鼠+小家鼠+丛林鼠群落(D);山坡荒地灌丛杂草和山玉米生态小区——小家鼠+黄胸鼠+丛林鼠群落(E);低山丘陵甘蔗、水稻生态小区,黄毛鼠+小家鼠+板齿鼠群落(F);农村住宅生态小区,小家鼠+黄胸鼠+褐家鼠群落(G)。更多还原

【Abstract】 In the present study, 627 specimens of the small wild animals were collected from farmland of the southern edge of western hilly area of the Guangxi province in Dec. 1989 to May 1990. The collection comprises 16 species of small wild animals, belonging to 2 orders, 3 families, and 4 genera. There are 13 species of the small wild animals in Muridae, as Rattus rattoides etc, making up 81.25% of total of the small animals, Among them 3 species belong to Mas genera, making up 18.75% of the small wild animalls. There are 2 species in the Soricidae family and 1 species in the Rhizomydae taking the second place of the small wild animal. They belong to Oriental species.Based on the faunistical character of animals and the natural environmental conditions, the farmland of the southern part edge of the western hilly area of Guangxi province may be divided into 7 communities of the small animals. Community A-Small plain flatland: Rattus ratt oides Musmusculus+R.flavipectus. community B-Bank of river and terrace: Mus musculus + R. rattoides Suncus murinus.Community C-Valley of hill two-bank; R.rattoides. There are 6 spec ies of small animals in the community. The structure ratio of R. ratloides is 81.82%. of small animals numeriecolly. Community D-Slopeland of foothill: R.rattoides + Mus musculus+Mus famulus cookii. Community E-Wasteland in slopeland of foothill: Mus musculus +R. fldvipectus + N. famulus cookii. Community F-Low hilliness: R. rattoides+M. musculus-r Bondicota indica. Comm unity G-Village: M.musculus + R.flavipectus + R.norvegicus.更多还原
