This part is the first part of LY/T 1662, with reference to GB/T 14721.1-1993 "Forestry Resource Classification and Code Forest Type",
LY/T 1438-1999 "Forest Resource Code Forest Survey", LY/T 1439-1999 "Forest Resource Code Tree Species".
This section incorporates and adjusts LY/T 1438-1999 Forest Resources Code Forest Survey, LY/T 1439-1999 Forest Resources
Applicable content in Code Tree, and LY/T 1438-1999 Forest Resources Code Forest Survey, LY/T 1439-1999
The main changes in the resource code tree are as follows.
This part specifies the classification, organization and coding of non-spatial data of forest resources in the digital forestry system. Suitable for digital forestry
National Forest Resources Continuous Inventory (referred to as Category 1 Survey), Forest Resources Planning and Design Survey (referred to as Type 2 Survey) and Operational Design Survey (referred to as
Three types of surveys) data collection, classification and digital storage can also be used as part of forest resource management, resource and environmental information system construction.
Test standards.
Under the premise of extensive reference to existing national standards and industry standards, this section currently divides forest resource data into 13 categories and uses them.
The two-digit number is used as the category identification code, and based on this, a combination of hierarchical coding and sequential coding is used for coding.
It should be noted that with the transformation of forestry from timber production to ecological environment construction, the original use of forest plants by type and forest
The classification system of the "main tree species and tree species groups" of the classification may cause the same tree species to appear in different utilization type groups and cannot satisfy the data.
The “uniqueness” requirement of the item code, therefore, this part specifies the classification, classification and coding of such data by plant taxonomy. Currently included
LY/T 1439-1999 All items in the category of Forest Resources Code Tree, and added some trees, shrubs, herbs, bamboo strips
Therefore, this type of data currently includes 103 families, 268 genera, and 1510 species. For the convenience of use, this type of data is in Chinese, genus, and species.
The Chinese Pinyin order is arranged and managed.
Because the classification of tree species in the forest resources survey is not uniform, it is difficult to meet the requirements of uniqueness and integrity, so this part
The "main tree group" is no longer divided.
Appendix A to Appendix N of this part are normative appendices.

Digital Forestry Standards and Specifications
Part 1. Non-spatial data standards for forest resources
1 Scope
This part of LY/T 1662 specifies the classification, organization and coding of non-spatial data on forest resources in the digital forestry system.
This section applies to the continuous inventory of national forest resources in digital forestry (referred to as a type of survey), forest resource planning and design survey (referred to as two
Class surveys and job design surveys (referred to as three types of surveys) data collection, classification and digital storage, can also be used as forest resource management, resources
Reference standards for work such as the construction of environmental information systems.

3 Terms and definitions
The following terms and definitions apply to this part of LY/T 1662.
3.1
Forests, forests, woodlands, and wildlife, plants, and microorganisms that depend on forests, trees, and woodlands.
3.2
The continuous inventory of national forest resources is referred to as a type of inventory, which is an important part of the national forest resource monitoring system.
The method is to set up a fixed plot in the overall scope and to continuously measure the forest resources continuously. Take the province (autonomous region, municipality) as a single
The position is reviewed every 5 years.
3.3
The forest resource planning and design survey is referred to as the second-class survey and is an important part of the local forest resource monitoring system. State-owned forestry
Forest management units such as bureaus (areas), nature reserves, forest parks, or county-level administrative divisions are designated as investigation units, mainly using small-scale division surveys.
Methods, respectively, to identify the forest resources within the overall scope of the Shantou plot, in order to meet the forest management plan preparation, overall design, forestry zoning and planning
Forest resources inventory required for design and so on. The interval between forest resource planning and design surveys is generally 10 years.
3.4
The job design survey is referred to as the three types of surveys and is a survey conducted for the design of the homework. Should be based on the second type of investigation, according to the planning design
The requirements are carried out year by year, and forest resources should be implemented in specific cutting areas or a certain range of operating plots.
