通过华北落叶松不同立地类型、栽植季节和整地方法造林试验结果表明：苗圃地与造林地生态条件的差异是造成春季造林成活率低的主要原因；光、热、水诸因子是影响幼林生长的主导因子；平台地为最佳立地类型，阳坡、半阳坡适合于培育小径材，阴坡适合于培育中、大径材；常规造林中，应采用小穴整地，营造速生丰产林，宜采用大穴整地。
According to different site types of Larix principis-rupprechtii, planting season and site-preparation methods, the results of afforestation experiment showed that the difference of ecological conditions between nursery and afforestation land was the main reason of low afforestation survival rate in spring. The factors of light, heat and water affected the growth of young plantation Dominant factors; the platform is the best site type, the sunny slopes and semi-sunny slopes are suitable for cultivating small diameter timber and the shady slopes are suitable for cultivating medium and large diameter timber. In conventional afforestation, Great site preparation.
