Population dynamics of soil microorganisms in deteriorate grassland in West Region of China

摘要：

Introduction Animal husbandry is the most important sector of West Region of Chinese economy,and it accounts,for example,45.36％ and 50.06％ of total agricultural output value in Inner Mongolia and Sichuan province respectively (CAYEB,2006).In recent years,sustained overgrazing and rodent.s destruction are responsible for more than 50％ degradation of grassland in western China,which causes serious social and economical problems in the region.To prevent deteriorate,intensive multidisciplinary researches have been performed.However,there is little documented information on microorganisms population changes in the region though it is well known that soil microorganisms play an important and vital role in grassland ecosystem.The objectives of present study focused on enumerating and detecting different groups of microorganisms.population dynamics in the region.
