Abstract: Based on quantitative analyzing the economic benefits and fixed position measuring the indexes of soil fertility, regeneration of cut woodland and water and soil preserving, using Multi objectives Decision and Analytic Hierarchy process, the comprehensive benefits(economic and ecological)of different harvesting and cultivating operation systems were calculated in this paper. The results showed that the operation system which composed by 40% selective cutting, skidding by man force, removing slash in strips and natural regeneration with man promoting is the optimum model for natural secondary forests of Masson pine. The model is suitable to be used in the north of Fujian Province and other similar areas.
