摘　　要：立地类型划分与抗逆树种选择是半干旱风沙区适地适树造林的技术关键。通过对山西省森林立地类型系统的分类,区划出半干旱风沙区的土石山、黄土丘陵、盆地河滩3种立地类型小区,从中划分出9种立地类型亚区和20种立地类型,并根据不同立地类型的特征、指示植物种类和近60 a来人工造林树种的生态适应性,提出了不同立地类型抗逆树种的选择。The division of site type and selection of resistant species are key techniques to afforestation of matching trees with site conditions in semiarid sand area. By the classification of forest site type in Shanxi Province, three site districts were obtained： rocky land of semiarid sand area, hilly land, and basin or flood land, which included 9 subregions and 20 site types. According to site type characteristics, indicator plant species and ecological adaptation of afforesation for 60 years, resistant species was put forward for different sites.
