Abstract: The study was made in the heavily frigid region of northeastern China from May to September in1997.The relationship between seasonal variation of soil fauna and microbial biomass and 14 ecological factors was studied, and the primary and secondary factors affecting soil faunas and microorganisms were sought out, in grey connected analysis.Data set was composed of soil faunas and 4 ecological factors (catalase, dehydrolgenase, inorganic Ptransformation and residual decomposition rate). Five grey models[GM(1,5)] were established.
