3 Terms and definitions

The following terms and definitions apply to this document:

Structure-based forest management the forest structure optimization management technology based on the spatial relationship of 4 nearest neighboring trees is called structured forest management for short: Structured forest economy the camp is aimed at cultivating healthy and stable forests, adheres to the business philosophy of tree-oriented, cultivation-oriented, and ecological priority, and uses natural climax communities the general law of (Healthy and Stable Forest Communities) is the paradigm: It uses the optimization of the forest stand spatial structure as a means, and relies on the spatial structure Forest management technology that arranges management measures during natural growth and succession:

Stratified forestlayer the level of forest stand can be divided by tree height, expressed by forest level:

Standgrowth

The index reflecting the forest stand vigor is expressed by the ratio of the actual forest stand area to the potential forest stand area:

Standcrowdeddegree

An indicator of stand density: Used to quantify the degree of crowding between trees:

Objectivetreespecies Tree species suitable for local climate and site conditions, capable of stable growth, and in line with business objectives:

[GB/T 15781-2015, definition 3:2] 3.6 Objectivetreesspecies(orgroup)competition Reflect the dominance degree of the target tree species (group) in the forest stand, expressed by the combination of size ratio and relative significance:
