【摘要】 以山东聊城分布的7种蛇类作为研究对象,探讨了鲁西平原区蛇类的群落结构和分布格局。结果表明,该区蛇类平均分布密度较高的是白条锦蛇Elaphe dione、赤链蛇Dinodon rufozonatum和虎斑颈槽蛇大陆亚种Rhabdo-phistigrina lateralis。多数蛇类倾向于选择湿地周边、边缘富有灌草丛的农田区以及有丰富草被的居民区等为栖息地,该区蛇类的栖息地选择有着显著的不重叠性。更多还原

【Abstract】 The distribution patterns of snakes in western Shandong Province have been surveyed since 2001.The results show that Elaphe dione,Dinodon rufozonatum and Rhabdophis tigrina lateralis were dominant out of the 7 species of snakes in this region.Most snakes preferred to live in the wetland,cropland area surrounded by shrubs and residential areas surrounded by grass.Moreover,habitat selection of snakes in the area was obviously non-overlapping.更多还原
