Abstract:

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.

Key words: Three-North Shelterbelt Project, shrubs forests, development thinking, ecological construction, protective forest management
