摘　　要：对于西北地区森林培育质量的评价应主要以人工林成长期水土保持功能的发展速度和成熟期持续发挥作用的保持水土功能为标准。西北地区高质量的人工林不仅要较快地具有高效的水土保持功能,而且要能够持续地具有生态效益。土壤干燥化和有害生物防治问题与西北地区森林培育密切相关。森林培育质量的持续提高不仅要依靠森林培育学科自身的发展,而且有赖于相关学科的发展和进步。Assessment on the silviculture quality in the northwest region is made on the criteria concerning rapid development of artificial plantations in terms of its function in soil and water conservation in a long period of time and its sustained performance of soil and water conservation in the mature period. Forests of high quality in the northwest region not only have to be of efficient significance in soil and water conservation, but also of sustained role in ecological improvement. Dry soil and pest problems are closely related to the silviculture quality, the enhancement of which will definitely depend on the discipline development itself and progress of relevant disciplines.
