This standard introduces the following contents of LY/T 1496-1999 Revised. --- Changed the practice of determining growth indicators only in the past, only in the division of production areas. On the basis of the division of the production area, according to the location Develop growth indicators at several levels. --- Re-established the entire growth indicator. --- Major modifications have been made to the cultivation techniques (afforestation density, land preparation, thinning, etc.). Appendix A, Appendix B and Appendix C of this standard are informative annexes. This standard is proposed and managed by the State Forestry Administration. This standard is mainly drafted by. Guizhou University Institute of Afforestation Ecology, State Forestry Administration Fast-growing and high-yield timber forest base construction project management office The Office, the Guangxi Academy of Forestry, and the Tropical Forestry Experimental Center of the Chinese Academy of Forestry.

Pinus massoniana fast-growing and high-yield forest1 ScopeThis standard specifies the growth indicators of Pinus massoniana fast-growing and high-yield forests and the technical measures to be taken. This standard is applicable to the construction of construction timber forest and pulpwood forest in Pinus massoniana fast-growing and high-yield forest.2 Normative referencesThe terms in the following documents become the terms of this standard by reference to this standard. All dated references, followed by all Modifications (not including errata content) or revisions do not apply to this standard, however, parties to agreements based on this standard are encouraged to study Is it possible to use the latest version of these files?

GB 2772 forest seed inspection procedures GB 6000 Main afforestation tree seedling quality grading GB 7908 forest tree seed quality classification GB/T 8822.6 Pinus massoniana seed zoning GB/T 15776 Afforestation Technical Regulations3 Terms and definitionsThe following terms and definitions apply to this standard. 3.1 The basic units of site classification are different independent plots that are divided according to the differences in ecological environment. The same site type, its environmental cause Sub-combinations (eg small terrain, parent rock, parent material, soil, microclimate, plant community), forest productivity and management and utilization are roughly similar. 3.2 Status index A quantitative indicator reflecting the quality of the site and the productivity of the forest land, directly using the standard age of each species (the standard age of Pinus masson is 20 years) The average height of the forest's dominant wood is expressed. 3.3 3.3.1 Its wood is mainly used for decoration, decoration, pillars, transportation, etc. of buildings, and can be further divided into large diameter timber, medium diameter timber and small diameter timber. Large diameter timber. trees with a diameter of 26 (cm) and above; Medium-diameter timber. trees with a diameter of 18 to 24 (cm) in diameter; Small diameter timber. trees with a diameter of 16 (cm) and below. (with 2cm as a scale) 3.3.2 To cultivate fast-growing and high-yield forests for the production of wood pulp and papermaking materials.4 division of production areasAccording to the natural geographical characteristics and growth of the various distribution areas of Pinus massoniana, and taking into account the management tradition, the natural distribution of Pinus massoniana is divided into three. ...... |
