GB/T15163-2004
This standard replaces (B/T15163-1994 Technical Specification for Mountain (Sand) Narrow Forests). Compared with GB/T15163-1994, this standard has the following major changes:
Added palace and normative reference documents:
: The connotation, scope and conditions of closed mountain (sand) afforestation have been expanded and redefined: Closure and cultivation of non-forested land and sparse woodland, The key terms such as forested land and sparse forest land closure, closure area, closure status, closure, original closure, new closure, unsealing and continued closure are defined. In order to facilitate operation and strengthen management, the north-south boundary division of closure (sand) afforestation is linked to the national administrative regions: the closure conditions of non-forested land and sparse forest land are adjusted and specified; the conditions and technical measures for closure of extensive forest land and shrub forest land are added. The closure type, closure force mode, closure period, etc. are separated from the planning and design of closure (sand) afforestation and form a separate chapter; the design of closure and forest protection measures is simplified, and their main contents are moved to the chapter on closure operations; the closure period is revised to make it consistent with the effectiveness survey time. The design content of mountain (sand) closure and afforestation, the methods and contents of field surveys, and the technical requirements for small-scale zoning and surveys have been simplified. The "Main Technical Regulations for Forest Resource Planning, Design and Survey" are directly adopted; the internal design uses LY5141·1999 "Afforestation. The composition and depth requirements of national documents for engineering construction projects (trial)"; the inspection and acceptance system as well as the qualified conditions for white inspection and verification have been added; the qualified standards for the effectiveness of closure and cultivation of non-forested land and sparsely forested land have been revised, and the qualified standards for the effectiveness of closure and cultivation of forested land and wooded land have been added, and the survey content has been increased;
: In addition to the fixed standard land survey and other contents: the format of some appendices has been revised and added, and the appendix A, Appendix B, Appendix, and Appendix of this standard are This standard is proposed by the State Forestry Administration. This standard is under the jurisdiction of the State Forestry Administration. The responsible drafting unit of this standard is the State Forestry Administration Survey, Planning and Design Institute. The participating drafting units of this standard are: Zhejiang Forestry Department, Fujian Forestry Department, Su Forestry Department, Shanxi Forestry Department, Jiangxi Forestry Department, and Heilongjiang Forest Industry Group Forestry Bureau. The main drafters of this standard are: Tang Xiaoping, Gan Enling, Fan Xibin, Weng Guoci, Shi Hongchun, Zhang Jun, Cheng Xiaoling, and Jiang Sannai. This standard was first issued in 1994 and revised for the first time in 2004. 1 Scope Technical regulations for closed mountain (sand) moss forests GB/T 15163--2004
This standard specifies the objects, types, methods and years of closed-mountain (sand) afforestation, as well as the principles and technical requirements for closed-mountain (sand) afforestation planning and design, closed-mountain (sand) afforestation operations, inspection and effectiveness investigation and file management. This standard is applicable to closed-mountain (banknote) afforestation on suitable forest land, non-standing timber forest land, sparse forest land, and closed-mountain (banknote) afforestation on low-quality, low-efficiency forest land and shrub forest land throughout the country.

6.1 Closure types of non-forested land and sparse forested land
Based on the survey of the small group, according to the site conditions, as well as the conditions of mother trees, young trees, and root stocks, the closure of non-forested land and sparse forested land is divided into the following five closure types:
a) Tree-growing type: sparse forests formed by artificial gathering and in areas suitable for the growth of trees, forests without standing trees and suitable forests that meet the closure conditions and where mother trees, young trees, seedlings, and root stocks of tree species are dominant should be closed as tree-type trees and shrubs: other sparse forests and in areas suitable for the growth of trees, forests without standing trees and suitable forests that meet the closure conditions but mother trees, young trees, seedlings, and root stocks of tree species are not dominant should be closed as shrubs. Shrubs: forests without standing trees and suitable forests that meet the closure conditions and reach the upper limit of tree growth and meet the closure conditions should be closed as shrubs. e
d) Shrub and grass type: For areas suitable for forestation in bad site conditions, such as mountains, steep slopes, rocky areas, sandy land or dry areas, it is advisable to close them as shrub and grass type.
e) Bamboo forest type: For plots that meet the conditions for closing bamboo, clump bamboo or miscellaneous bamboo: 6.2 Closure types of forest land and shrub forest land
Forest land and shrub forest land should cultivate wood type. 7 Determination of enclosure method
7.1 Full enclosure
Remote areas, upper reaches of rivers, water catchment areas, areas with severe soil erosion, areas with particularly serious wind and sand hazards, and enclosure areas with relatively solid vegetation restoration should be fully closed.

Semi-enclosure can be adopted in enclosure areas with certain target tree species, good growth and large forest coverage. 7.3 Rotational Closure
For closed areas that are not ecologically fragile and where local people have practical difficulties in production, life and fuel, rotational closure can be used. 8 Closure Period
The closure period is determined according to the closure conditions and closure purpose of the closed area. The general closure period is shown in Table 1.

10.3.1.1 For plots in the enclosure area where shrubs and shrubs have strong natural seeding ability and the plots are affected by the large coverage of shrubs and grasses, strip or block weeding and land preparation can be carried out to promote artificial regeneration. 10.3.1.2 Young trees and shrubs and mother trees with the ability to sprout in the closed breeding area can be pruned or rooted to strengthen as needed to enhance their ability.
10.3.1.3 For intercropping plots with insufficient natural breeding capacity or uneven distribution of seedlings and saplings in the closed breeding area, replanting or reseeding can be carried out according to the requirements of the closed breeding type.
10.3.1.4: In the sandy closed breeding area, sand barriers and sand fixation measures can be taken in the mobile sand land (hills) with strong wind and sand activities to promote closed breeding. 10.3.1.5 In the closed breeding area of the district, flood irrigation can be carried out in areas with conditions to promote the growth of mother trees and saplings. 10.3.1.6 During the closed breeding period, according to local conditions, for the cultivation and irrigating tree species that meet the closed breeding standards or have higher value, weeding, soil loosening, weeding, intershading, drought resistance and other cultivation measures can be taken. 10.3.2 Afforestation in existing forest land and shrub forest land
10.3.2.1 For small plots with few trees, low density and coverage, and uneven distribution in the closed-off area, adopt the method of promoting afforestation by replanting and reseeding under the canopy and in the open space in the forest.
10.3.2.2 For small plots with a single tree species composition and simple structural layers, adopt the method of point-shaped and group-shaped felling to let light penetrate, promote the growth of young and saplings under the forest, and gradually form a forest stand with a multi-layer structure of different ages. 10.4 Disaster prevention
