摘　　要：对国外松工业用材林高效集约培育不同营林措施及其不同方式投入成本与林分生长效应和经济效益的关系作出分析与评价 ,以提出投资分配合理的林分高效栽培制度。依据对各重要营林措施的比较试验结果提出 ,应用形态改良壮苗 ,严格栽植检查验收制度 ;对幼林地的土壤管理应因地适时适度地采用相应措施 ,合理投入 ,以保障幼林适时达到郁闭成林 ;强化密度管理措施 ,保证林分生长在预定的限期内达到郁闭和间伐 (或主伐 )的状态。通过对各主要措施不同方式经济效益的比较分析 ,提出了国外松工业用材林密度调控方案和土壤管理配套方案 。This paper analysed the different measures of high-efficiency intensive culture of industrial timber forest of exotic pines and relationship among forestation cost,growth effect of forest stand and economic benefits,in order to propose high-efficiency culture system.According to the results of comparision among various important measures of forest construction,this paper proposed culture pattern.Morphological improvement could be applied to make the seedlings strong and strict system of inspection and acceptance of afforestation should be formlated;On management of soil of young forests,relative measures should be properly applied in accordance with the time and the place,to ensure that yong forests could timely reach the condition of closing;management of density should strongthen,to assure that the forest stands could close within the planned period and reach the condition of intermediate cutting.By analysis on economic benefits of various important mesure of forest construction,scheme of density regulation of industrial timber forest of pines and scheme of soil management were proposed to form the best patterm of through management.
