Abstract

By the theory and method of increase model , with statistical data in Fifty Years of Linan , the Gompertz increase model =6 exp[ -5.802 0 e-0.367 9 t] was established , which predicted the output value of forest products .The model corresponded more to practicality and attained high rigidity .The relative error was 0.008 2 % between prediction and actual value , correlative index was 0.999 2 .This predicting measure is simple and easy to use , and has practical significance , it can also be used in predicting the output of cash forests and the volume of forestry resource consumption etc .It offers decision warranty and raises the power of general control for forestry management .
