摘　　要：在太行山北段雁门关进行了9个树种的荒山造林对比试验,应用EM50土壤水分测定系统对油松容器苗不同规格整地、不同覆盖处理的土壤水分进行动态监测。结果表明:除油松、樟子松外,杜松、沙地柏对寒旱瘠薄困难立地有良好的适应性;以土壤含水量的单位增量费用为标准,确定中小规格的整地(0.8 m×0.6 m×0.4 m,0.6 m×0.5 m×0.4 m)、"石块+地膜双层覆盖"或"石块单层覆盖"方法是太行山北段困难立地最经济有效的植被恢复技术措施,提出了基于抗旱树种容器苗及相关配套造林技术集成的植被恢复技术对策。Comparative experiments of 9 species plant trees in Yanmenguan in North Taihang Mountain, soil moisture of container seedling of Pinus tabulaeformis in different preparation process and different coverage treatment were monitored dynamically with EMS0 monitoring system of soil moisture. The results showed that except Pinus tabulaeformis and Pinus sylvestnis var. mongolica Litv. , Juniperus rigida and Sabina vulgavis were suitable in frigid and arid of sites. Preparation process of 0. 8 m × 0. 6 m ×0. 4 m and 0. 6 m × 0. 5 m× 0.4 m and coverage treatment of stone ＋ coverage of two layers plastic mulching or coverage of one layer stone were most economical technology of vegetation construction in North Taihang Mountain with expense of added soil moisture per unit as a standard. The paper supported technology of vegeation construc- tion based on container seedling of drought-resistant trees and relative supporting facilities.
