摘　　要：在黄土高原沟壑地区,如何提高油松造林成活率,是目前面临的突出问题。采用随机抽样调查法对泾川县影响油松造林成活率的主要因素进行了分析。结果表明:选择适宜的栽植时间、立地条件和苗木规格是提高油松造林成活率的关键措施;在油松造林方面,应注重调查规划,科学编制设计;选择阴坡和半阴坡立地类型,清明之前栽植,采用带土球或营养钵苗木,可有效提高造林成活率。In the gully region of the Loess Plateau, how to improve the survival rate of Pinus tabulaeformis is a prominent problem. A random sample survey was conducted to analyze the main factors affecting the survival rate of Pinus tabulaeformis . Result shows that selecting the appropriate planting time, site conditions and seedling size specifications are the key measures to improve the survival rate of Pinus tabulaeformis . In the aspect of afforestation of Pinus tabulaeformis , attention should be paid to investigation planning, scientific design, selection of the type of shady slope and semi-shady slope site, planting before Qingming Festival, and using soil ball or nutrient seedlings can effectively increase the survival rate of afforestation.
