Abstract

The invention discloses a soil layer structure contrastive analysis method and a reconstruction method thereof, and belongs to the technical field of forestry soil layer structure analysis and reconstruction. The soil layer structure contrastive analysis method comprises the following steps: (1) measuring a soil layer structure Z of a target area; (2) according to a target tree species, searching an original forest or a natural secondary forest which has the same climatic zone as the target region, is close to the target region in geographic position and grows with the target tree species; (3) measuring a soil layer structure N in the original forest or the natural secondary forest at a position near a naturally updated sapling of the target tree species; and (4) comparing the difference between the soil layer structure Z and the soil layer structure N. Through a relatively simple technical means, the ecological interaction between the forest trees and the soil is fully utilized under the minimum human intervention, the positive effect of plant growth on the environment and the land and the positive feedback of the land on the plants are exerted, and the naturally maintained ecological balance of the trees and the soil can be realized within the shortest time.

Description

technical field [0001] The invention belongs to the technical field of forestry soil soil layer structure analysis and reconstruction, and in particular relates to a method for comparative analysis of soil layer structure and a reconstruction method thereof. Background technique [0002] "Forestry soil" refers to the soil used by forestry, and generally refers to the outermost layer of the earth's crust where trees participate in the conversion of matter and energy. Relative to soil, the concept of forestry soil is mainly based on the characteristics of soil utilization, and is used to refer to the soil under natural forest, secondary forest and artificial forest, as well as barren mountains and wasteland suitable for forest. Forestry soil includes not only the forest soil developed under the influence of modern forests, but also a small part of agricultural soil and grassland soil, as well as some agriculturally called non-soil cuttings, slag, peat, tidal flats, etc. [00...
