摘　　要：采用正交试验法进行更新设计，通过对试验区的１０ａ田间观测．结果表明，天然过伐林采伐迹地人工更新较好的设计为：择伐迹地，采伐强度４０％以下，冠下丛植更新红松，每穴３株，株行距３ｍ×３ｍ，也可营造红皮云杉；皆伐迹地，更新长白落叶松，株行距１ｍ×３ｍ（１ｍ×２ｍ），并借助天然更新保留水、黄等珍贵阔叶树，使之形成“人天混”The orthogonal sign was adopted in the project.The result showed that the better plans for artificial regeneration in logged area of natural hag were as follow:inselective cutting site,the cutting intensity was less than 40%,Korean pine was planted in group under crowns,3 per hillsand,row spacing 3m×3m.It was possible to plant spruce also;Korean larch was planted in clear cutting area,row spacing 1m×3m(1m×2m),and by natural regeneration.
