摘　　要：以土壤水分条件及地形等因素为依据 ,进行了立地条件类型的划分 ,共划分了 3个类型组和 9个类型 ,并提出了小流域林草布局的典型模式。根据立地条件类型划分和小流域布局模式可以看出 ,延安研究区有条件发展乔木林 ,但并不是到处都可发展乔木林 ,因此 ,依据立地条件类型进行造林种草的合理布局进行植被建设是取得成功的必要措施。The standing conditions are classified into three type groups and nine types,and the setting mode of forestry and small watershed is put forward by conditions of soil moisture and landform,etc..According to this,arboreal forestry can be developed in some areas of Yan'an experimental region.Therefore,the rational setting of afforestation and grass planting by the type of standing conditions is the essential measure to make successful result.
