摘要: 甘肃安西荒漠鼠类群落多样性与植物密度和植被复盖度呈显著负相关;与植物的种数、高度、多样性、优势度无关;与海拔高度和降水量也无关。荒漠地区地下水位的深浅对地下栖居的鼠类有直接限制作用。
关键词: 荒漠, 鼠类, 群落多样性, 植物密度, 植被复盖度
Abstract: This study was conducted in Anxi desert area of Western Gansu from April to June,1988.Thirteen rodent communities were investigated for dealing with the inter-relationships between communities of rodents and their habitats. Eight species of rodents were captured,and the numbers of species in communities increased from l species to 7 species.The community diversity of rodents was negativelyinterrelated with coverage of vegetation and the plant density significantly (r =- 0.5869,p< 0.05; r= -0.6835,p< 0.01),and it was not interrelated with the numbers of plant species,plant height diversity and dominances,neither with altitude and annual rainful. There are significant dlfferences among rodents in selecting ground water level and substrates.The great majority of species have tended to selecting gobi.There are a few species in the communities where ground water level is higher.
Key words: Desert, Rodent, Community diversity, Plant densit, Plant coverage
