摘　　要：为了探明欧李在黄土丘陵沟壑区不同立地类型的生长差异,选择山西省吕梁市柳林县留誉镇槐树沟村黄土丘陵沟壑区为试验区,调查了7种立地类型欧李株丛地上部和地下部的形态指标。结果表明,不同立地类型栽植欧李均能正常生长,但差异较大,隶属函数综合评价得分从高到低分别为坝地、梯田(阳面)、撩壕阳坡、软埂阳坡、撩壕阴坡、硬埂阳坡及立壁(阳面)。坝地欧李长势最强,其株高、基生新梢长度及粗度分别达到80.57,60.24 cm,3.04 mm,均极显著高于其他立地;立壁欧李长势最弱,其冠幅、根颈直径、根粗和根状茎数量及粗度分别为32.18 cm,9.49,3.60 mm,0.33条,0.27 mm,均极显著低于其他立地,但根冠比最大(9.81∶1);其他立地类型欧李生长情况介于坝地和立壁之间。研究旨在为黄土丘陵沟壑区的欧李种植提供理论和实践依据。To study the growth difference of Chinese dwarf cherry from different site types in hilly and gully regions of the loess plateau, the test area for hilly and gully regions of the loess plateau in Huaishugou village, Liuyu town, Liulin county, Luliang city, Shanxi province were selected, and the aerial and underground morphological indices of Chinese dwarf cherry were surveyed and analyzed in seven site types. The results showed that Chinese dwarf cherry grew normally in seven sites, whereas great differences on growth were observed. The descending rankings of the comprehensive evaluation score on the membership function were dam land, terrace, trench in sunny slope, soft ridge in sunny slope, trench in shady slope, hard ridge in sunny slope and vertical weir. Chinese dwarf cherry grew best on dam land, their average plant height, length and diameter of new basal shoot were 80.57 cm, 60.24 cm and 3.04 mm, respectively,which were significantly higher than other site types. Chinese dwarf cherry planted on vertical weir had the weakest growth potential, their average crown width, collard diameter, root diameter, rhizome quantity and rhizome diameter were 32.18 cm, 9.49 mm, 3.60 mm, 0.33 and 0.27 mm, respectively, which were significantly lower than other site types, however their average root-shoot ratio（9.81∶1）was the greatest. The growth condition of Chinese dwarf cherry in other site types were the medium of dam land and vertical weir. This study aims at providing the theoretical and practical basis for planting of Chinese dwarf cherry in hilly and gully regions of the loess plateau.
