Abstract: The relationship between seasonal variation of soil active organic matters and 18 environmental factors were studied by grey connected analysis in the northeast heavy frigid region of China.The primary and secondary factors of influencing the variation were founded out. Dota set was composed of the soil active organic matter and 4 environmentl fators(catalase,invertase,avaiable P and pH value), then the grey model [GM(0,5)]was established: X1(1)(K)=-3.962891X2(1)(K)- 0.4794922 X3(1)(K)0.8242188X4(1)(K)+ 9.273438X5(1)(K)-2.185547.
