摘　　要：为实现防护效益、经济效益、社会效益和生态效益多重目标,三北防护林体系工程的建设,在空间上要求布局合理,树种林分具备多样性和稳定性的特征。三北防护林体系的发展需科学研究防护林学,加大保护力度和修复自然生态系统,这就需要在防护林建设区域大力开展片状防护林近自然经营研究,加快发展乡土树种,宜乔则乔,宜灌则灌,宜草则草;在干旱半干旱区要提倡加大营造乡土灌木林,实行灌乔草相结合。从灌木林建设在三北工程中的发展前景、发展现状、重要作用及加快三北工程灌木林建设的基本思路几方面阐述了对灌木林建设的思考,为加快防护林体系建设的发展做出有益的努力。In order to achieve the multiple goals of protection,economic benefits,social benefits,and ecological benefits,the construction of the Three-North Shelterbelt System Project requires the diversity and stability of tree species and forest stands,and the rational layout in space.The development of the Three-North Shelterbelt System requires the scientific research of protective forest science and greater efforts are made to protect and repair natural ecosystems.In the protective forest construction area,we have vigorously carried out research on the natural management of protective forests,and accelerated the development of native tree species.In the arid and semi-arid areas,efforts are also made to promote the increase of native shrubs and implement combination of arbor,shrubs and grasses.This article elaborates the thinking on the construction of shrubbery from several aspects such as the development prospects,the current situation of development,the important function and the basic idea of shrubbery construction in the Three-North Project to promote the construction of shrubbery in the Three-North Project development and to make beneficial efforts to speed up the development of the shelterbelt system.
