摘　　要：为丰富种质资源,在黄土高原丘陵沟壑区引进乔木树种105个,分属于15科25属,进行筛选、驯化,鉴选出了适宜该区坡地生长的樟子松、油松、侧柏、刺槐,适宜沟底生长的山杨、胡杨、乌柳,经济树种梅杏、红枣、桃等8科12属90余个优良树种。并研究了其立地条件及水、肥需求规律,提出了不同树种立地范围。结果表明:刺槐耗水量较大但能提高土壤有机质含量;油松、侧柏耗水量较少适于旱坡地种植;杏宜种植于水肥条件较好的阳坡或半阴坡;梨阴坡、阳坡均可;枣应植于阳坡等。105 species （25 genera, 15 families） of trees were introduced and domesticated in hilly and gully area of Loess Plateau, the regularity of requirements for fertilizers and water and the growth conditions of trees were researched, more than 90 species （12 genera, 8 families） of fine trees suitable to local conditions were selected, and the models of dispositions area of tree species were studied.
