伐区采育结合作业优化模式的选择

Optimized models of logging-tending system in cutting areas.

在定量计算和分析闽北地区马尾松林各伐区采育结合作业系统的经济和生态效益的基础上 ,应用“系统集对分析方法”对其综合效益进行评价 ,结果表明 ,由 40 %择伐强度、原木人力集材、归带清理采伐迹地和人工促进天然更新等组合而成的作业模式是福建北部马尾松林的优化作业模式 ,适合于就近类似本试验自然条件的林区 .

The comprehensive advantages of different logging tending systems in Pinus massoniana forest cutting area were evaluated by set pair analysis,based on the comparison of their economic and ecological benefits.The results showed that the optimized model for P.massoniana forests in Northern Fujian comprised 40% selective cutting,manual skidding,clear cutting in ribbon,and natural regeneration with artificial aids,which could also be used in the nearby forests with conditions similar to the experimental area.
