摘　　要：在华北石质低山干旱阳坡,提高油松植苗造林成活率及生长量的关键,在于蓄水保墒。较大规格的反坡鱼鳞坑整地,辅以覆膜、覆草,可提高早春的地温,维持较高的土壤含水率,为油松苗木的成活及生长创造适宜的微域生态条件。The key techniqure to improve the survival and growth of Pinus tabulaeformis on dry south sides in lower rocky mountain in North China is to keep water for raising soil moisture. As a soil preperation measure, the large fish scale-like holes with inclination to slope,and mulching them with plastic film or grass have the advantages to increase soil temperature in early spring and to maintain a higher soil moisture. This may create the suitable ecological conditions in the micro onviornment for the plants to survive and grow.
