Abstract: B iogeography is the cross science of b io logy and geography to exp lore the spat ial d istribu tion pattern of the organ ism s ( popu lat ion, comm un ity etc. ) and th e m echan ism s th at generate and m aintain such pattern. For cen tu ries, b io log ists have stud ied d istribu tion pattern s of p lan ts and an mi als at d ifferen t spatial scales. W h ile few smi ilar stud ies has b een carried ou t for m icroorgan ism s in th e past due to the lmi itat ion of techn iques. Con sidering the s ign ificance of so il m icroorgan ism s in b iogeoch em ical cycling processes and m ainta in ing ecosy stem fun ct ion, know ledge of the spatial pattern s and m echan ism s involved in so il m icrob ial d istribu tion is fundam en tal to deve lop sound m an agem en t strateg ies of the terrestrial ecosystem s.
