The integral diffusion models were established using standardized ecological benefit dependent variable, regional independent variables and stand independent variables. Three important parameters including effective area coefficient, market approximation coefficient and conversion factors (According to the law of substitute goods, State Statistical Yearbook gets a reasonable price of the substitute goods and converts physical forest ecological benefit volume to money factors.). Then forest ecological benefits including water reservation, soil fixation, fertility reservation, CO_2 absorption, atmosphere purify, microclimate improvement, wind sand suppression, flood and draught mitigation, forest recreation, animal protection, plant protection and noise elimination n State-owned Forest Region in Heilongjiang Province were calculated.
