GB/T 15782-2009Code for silvicultural overall design (English PDF)

Foreword

This standard replaces GB/T 15782-1995 "intensively managed plantation timber base overall design regulations." this standard compared with GB/T 15782-1995, the main changes are as follows.

--- Standard name changed to "Afforestation overall design regulations," the overall design object "intensive farming afforestation timber base" to "create Forest ", expanding the scope of the standard;

--- General added Afforestation overall design to be prepared within the framework of the national key forestry construction plan and related documents Requirements;

--- Increasing the overall design task, depth, based on the preparation unit;

--- Provisions relating to the previous zoning and forest management into the same business division system, only a small class through a major Camp direction (see 8.1);

--- The preparation and afforestation model of technical indicators to comply with the relevant technical standards (see 10.1.3);

--- Provisions should be adopted when the satellite image data is updated in small classes (see 9.2.2.4);

--- Provisions should adopt geographic information systems software development drawings (see 10.1);

--- Provision should be using GIS software to determine the scale of construction (see 10.2);

--- Status map, site type maps, design printout scale and increased 1.50000 1.100000 two specifications (see Section Chapter 21).

--- Field survey and design industry in the two parts of the text were extracted, compressed, indicating that it has removed the concrete is well known (see para.

9,12, 13 and Chapter 14);

--- Added Appendix B "overall preparation of outline design specification." Appendix C of this standard is a normative appendix, Appendix A, Appendix B is an informative annex.

This standard is proposed and managed by the State Forestry Administration.

This standard was drafted. Forest Inventory and Planning Institute.

1 Scope

This standard specifies the overall design of the preparation of afforestation tasks, according to the depth, contents, methods and requirements and programming.

This standard applies to the overall design of the National Afforestation key forestry projects. Other afforestation projects can be implemented by reference.

3 General

3.1 Afforestation overall design to be prepared within the framework of the national key forestry construction plan and related documents will be, and should follow the ecological validity Yi priority, ecological, economic and social principle of unity.

3.2 afforestation of land for construction should be determined in line with the overall land use planning, forest land can not be converted to other land uses, nor will the basic agricultural Grain fields included in the scope.

3.3 should follow the principle of Forest Classification Management. Mountain Afforestation priority should be given in favor of forest types Ecological Construction. Orchard-type forests, short rotation Cutting of timber, raw materials should not be too large proportion of the forest, where the forest type orchard planting area should not exceed 30% of the total area of \u200b\u200bafforestation.
