中文摘要	2009-2011年4月、7月和10月(春、夏、秋季),在内蒙古阿拉善荒漠区选择了4种不同干扰生境,分别为开垦区、轮牧区、过牧区和禁牧区,采用铗日法对生境中的啮齿动物进行了调查,运用冗余分析法(Redundancy Analysis,RDA)研究了不同季节啮齿动物群落特征及其与植物因子之间的关系。结果表明,春、夏、秋3个季节啮齿动物群落物种多样性指数(H)在不同干扰生境间差异显著(P<0.05),春季啮齿动物群落多样性指数轮牧区最高(1.42),过牧区最低(0.91);夏季啮齿动物群落多样性开垦区最高(1.45),禁牧区最低(1.06);而秋季啮齿动物群落多样性过牧区最高(1.23),禁牧区最低(0.65)。冗余分析表明,春季和夏季灌木盖度和草本密度对荒漠啮齿动物群落组成的影响均显著,而秋季是草本密度和草本盖度对荒漠啮齿动物群落组成的影响显著。因此,植物盖度和密度是影响阿拉善荒漠啮齿动物群落结构的关键环境因子。
英文摘要	The rodent community were sampled by a trap-day method in four different disturbance habitats in April, uly and October ( spring,summer,autumn) from 2009 to 2011 in Alashan desert.The habitats were farmland, otational-grazing,over-grazing and prohibited-grazing areas,and the relationships between rodent community and lant factors were analyzed by Redundancy Analysis ( RDA) .The results showed that rodent community diversity ndices ( H) between different disturbance habitats were significant difference ( P < 0.05) in three seasons.The ighest diversity index of rodent community was found in rotational-grazing area ( 1.42) and the lowest was the over- razing area ( 0.91) in spring; in the same way,the highest index was found in farmland area ( 1.45) and the owest was the grazing-exclusion area ( 1.06) in summer; the highest index was found in over-grazing area ( 1.23) nd the lowest was the grazing-exclusion area ( 0.65) in autumn.The RDA with forward selection showed that variations f rodent community were significantly related to coverage of suffruticosa plant and density of herbaceous plant in spring and summer,density and coverage of herbaceous plant in autumn.We suggest that coverage and ensity of plants are the most important factors influencing the structures of rodent community in Alashan desert.
