| 摘 要： | 在定量计算各伐区采育作业模式的经济效益指标和定位测定由这些作业模式所造成的土壤肥力、迹地更新效果和蓄水保土等指标变化量的基础上，采用多目标决策和层次分析等方法，定量计算各伐区采育作业模式的综合效益（经济效益和生态效益），改变单纯以经济效益为唯一目标确定伐区工艺方案的传统方法。计算结果表明，“４０％择伐－原木人力集材－归带处理采作伐剩余物－人工促进天然更新”这一作业模式是马尾松天然次生林伐区作业的优

| 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. |
