Analysis of the rodent community diversity and species variation in the Junggar Basin
准噶尔盆地啮齿动物群落多样性与物种变化的分析

According to the results of sampling and cluster analysis, the rodent community in the Junggar Basin can be divided into four types: 1)farmland community dominated by Cricetulus migratorius and Mus musculus; 2)saxideserta community dominated by Meriones erythrourus and C.migratorius; 3)residential area community dominated by Rattus norvegiens WTBZ]and Mus musculus; 4)haloxylon eremic community dominated by Dipus sagitta and Meriones meridianus. The community 4 has the highest species diversity (1.670), and 3 has the lowest (0.979). In pace with the human economic activities, the desert community dominated by jird and jerboa will be replaced by the damp community dominated by M.musculus and C.migratourius. The new community pattern is that R.norvegicus will play an important role in some urban areas.
