一、造林地的选择云杉造林地类型分为火烧迹地、采伐迹地、荒山荒地以及箭竹类型、悬钩子类型、杂草地类型、灌木类型、萌生高山栎类型和阔叶疏林类型。按云杉2年生原床苗初植后的成活率和保存率,将造林地划分为三级:Ⅰ级为易成活型,Ⅱ级为较易成活型,Ⅲ级为不易成活型。试验表明,宜选用Ⅰ级和Ⅱ级林地作为云杉的造林地。Ⅰ级主要是悬沟子类型、灌木类型和落叶阔叶林类型;Ⅱ级则为

First, the choice of afforestation land Spruce Afforestation land types are divided into fire burned, deforested, barren hills and barren bamboo type, raspberry type, weed type, shrub type, initiation alpine oak type and broadleaf forest type. According to the survival rate and preservation rate of 2-year-old original seedlings of spruce, the afforestation land is divided into 3 grades: Ⅰ grade is easy to survive type, Ⅱ grade is relatively easy to survive type, Ⅲ grade is not easy to survive type. Experiments show that I and II should be selected as the afforestation land of spruce. Grade I is mainly hanging ditch subtype, shrub type and deciduous broadleaf forest type;
