Problems solved by technology

[0002] The forest is a key part of maintaining the ecological balance. In the previous model of artificial afforestation in open space, the forest land was divided into several pieces, planted on one of them, and then transplanted for afforestation after maturity. This kind of afforestation cycle is long, the investment is large, and the annual harvest The volume of forest trees is small, and the land utilization rate of forestation land is low
[0003] Therefore, aiming at the problems of high demand for manpower and material resources, long afforestation period, and low land utilization rate in artificial afforestation in some forestless lands, the present invention propose

Embodiment Construction

[0010] (1) Under the conditions of artificial afforestation in non-forested land, firstly, the tree species in the forest stand are designed to be point-like mixed, and the best mixed ratio k is determined. 0 ; Based on experience or models, based on empirical models and local natural forest observation results, the afforestation tree species are divided into three age classes I, II, and III, and the optimal density N of each age class is determined 1 , N 2 , N 3 .

[0011] (2) According to 10 4 / N i Determine the row spacing a of each age class i , according to the principle of uniform distribution, design tree pits in the afforestation area, and afforestation according to relevant requirements.

[0012] (3) In the first year of afforestation, according to N 1 Determine the planting quantity, plant the saplings of the I age class in the non-woodland, tend the saplings, and ensure the survival rate; when the I age class forest trees grow to the II age class, thinning is ...

Abstract

The invention relates to a method for artificial mingled forest afforesting design and intermediate cutting management through simulation of a natural forest. For the problem of artificial afforesting on non-forest land, an observation result of a local natural forest is simulated, and the technology of age-class intermediate cutting year by year is utilized, so that the problem of a single age class of artificial afforesting is solved, the land utilization is maximized in the afforesting process, an optical afforesting mode of an artificial forest is achieved, the purposes that the afforesting cycle is short and the annual harvest yield is high are achieved, and sustainable management is achieved.

Description

1. Technical field [0001] The invention relates to a design and thinning management method of artificial mixed forests that simulate natural forests. Aiming at the problem of artificial afforestation on ground without forest land, the observation results of local natural forests are simulated, and the age-graded thinning technology is used to solve the problem of single age-level artificial afforestation. The problem is to maximize land use in the process of afforestation, realize the best afforestation mode of plantations, achieve the purpose of short afforestation cycle, large annual harvest, and realize sustainable management. 2. Technical background [0002] The forest is a key part of maintaining the ecological balance. In the previous model of artificial afforestation in open space, the forest land was divided into several pieces, planted on one of them, and then transplanted for afforestation after maturity. This kind of afforestation cycle is long, the investment is l...
