  manual skidding
     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.
     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 .

Selecting five clear cutting operation with different skidding methods and selective cutting operation of thirty percent intensity, this paper compared the change level of soil physical and chemical properties after harvesting. With the consideration of the affection of skidding volume and the area of skidding trials, it also revealed the disturbance degree of soil after different harvesting methods by means of principle component analysis (PCA).The results indicated that the disturbance degree of soil physical...

Selecting five clear cutting operation with different skidding methods and selective cutting operation of thirty percent intensity, this paper compared the change level of soil physical and chemical properties after harvesting. With the consideration of the affection of skidding volume and the area of skidding trials, it also revealed the disturbance degree of soil after different harvesting methods by means of principle component analysis (PCA).The results indicated that the disturbance degree of soil physical and chemical properties of clear cutting by walking tractor skidding was at the most, the order of the disturbance degree of others were as followings: clear cutting by dirt chute skidding>clear cutting by push cart skidding>clear cutting by high lead cableway skidding>clear cutting by suspended cableway skidding>selective cutting by manual skidding.

选择5种不同集材方式的皆伐作业与采伐强度为30%的择伐作业,进行土壤理化性质指标变化程度的比较。在考虑各种作业的集材量和集材道面积的情况下,经主成分分析得出不同采伐、集材方式对林地土壤理化性质的干扰程度。认为,以皆伐作业手扶拖拉机集材为最大,其次为皆伐作业土滑道集材,其余依次为皆伐作业半悬索道集材,皆伐作业手拉板车集材,皆伐作业全悬索道集材,最低为择伐作业人力集材

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...

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.

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 ,“4 0 %择伐 -原木人力集材 -归带处理采伐剩余物 -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化作业模式 ,适合类似试验条件的林区借鉴
