Embodiment 1

[0048] Such as figure 1 , figure 2 Shown:

[0049] This embodiment combines the planting point configuration form (1) in the present invention to clearly and completely describe the technical solution implemented by the present invention ( figure 2 , top right). The described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0050] Select the appropriate afforestation location, afforestation tree species a and b, and the ratio of the number of trees. In this example, N a :N b = 40%: 60%, in this routine, the column spacing is 2m;

[0051] Afforestation adopts hole planting method, first determine the position of row and column, and fix the exact position of each tree;

[0052] Select any one or several planting point configuration form...

Abstract

The invention discloses a newly-built mixed forest building mode based on adjacent wood space relation. The building mode comprises a planting point randomization configuration form, and one or more configuration forms can be adopted; and according to the mixed building mode, simple and convenient interplant mixed planting is adopted, and the plant number ratio Na: Nb of the tree species a and b is determined according to the principle that the tree species are suitable for the land. By simulating random body distribution characteristics in a natural forest structure, an optimized planting point randomization configuration form is innovatively adopted, and in cooperation with an inter-plant tree species mixing mode, it is guaranteed that newly-built artificial forests play the characteristics of mixed forests in a short time. The mode is mainly applied to the construction mode design of new afforestation, more random bodies are constructed to be mixed with tree species, the tree space pattern diversity and the tree species mixing degree are improved, the afforestation cost is reduced, and meanwhile the afforestation effect is improved.

Description

technical field [0001] The invention relates to a newly-built mixed forest construction mode, in particular to a newly-built mixed forest construction mode based on the spatial relationship of adjacent trees, and belongs to the professional field of forest cultivation in forestry. Background technique [0002] The mixed forest construction model focuses on the mixed interbreeding method adopted by tree species, which determines the intermingled situation and intraspecific interspecific interactions in the mixed forest. Common construction modes of artificial mixed forests include inter-plant intermixing, inter-row intermixing, strip intermixing and block intermixing. Planting point configuration usually refers to the configuration of tree planting distribution form. [0003] The traditional plantation point configuration form usually adopts the row planting mode. Though this simple method is easy to the popularization and management of artificial forest, every seedling all...
