Method for improving biodiversity in desertification region

Abstract

The invention relates to a method for improving biodiversity in a desertification region, and relates to the field of desertification land restoration and governance. The method comprises the following steps: S1, determining a to-be-restored region; measuring the area of a to-be-restored desert, dividing the to-be-restored desert into blocky to-be-restored areas, carrying out area marking, and designating the sequence of restoration treatment; S2, laying a sand barrier; building a sand barrier is in the to-be-restored region; S3, planting dominant plants; and selecting dominant species from local psammophytes for planting according to a principle of matching species with the site; S4, planting leguminous shrub plants; selecting leguminous shrubs and dominant plants for mixed planting; and S5, planting leguminous herbaceous plants; planting the leguminous herbaceous plants after the dominant plants and the leguminous shrubs are planted for one year. The method has the advantages that the biological diversity of the desertification region is improved, and the desertification control effect is improved.

Description

technical field [0001] This application relates to the field of desertification land restoration and management, especially a method for enhancing biodiversity in desertification areas. Background technique [0002] Desert, also known as desert, full name sandy desert, refers to the area where the ground is completely covered by sand, arid, water-deficient, and plants are scarce. There are many reasons for deserts, including overgrazing, unreasonable felling of trees and so on. [0003] There are two difficulties in desert governance: 1. Poor water retention. The surface of the desert has a deep layer of fine sand, the gap between the fine sand is large, and the universal binding constraint between the fine sand is basically zero. Therefore, most of the rainwater will be lost directly from the gaps between the fine sands to the depths of the desert where plant roots cannot reach. At the same time, the temperature in the desert is high during the day and there is no vegetat...

AI Technical Summary

Problems solved by technology

At the same time, the temperature in the desert is high during the day, and there is no vegetation to cover it, so the water evaporates quickly. Even after it rains, the rainwater will evaporate quickly.

2. Poor fertilizer retention, the structure of desert soil is destroyed, soil nutrients have been lost, and the viscosity between the fine sand is insufficient, resulting in the inability of nutrients to attach to the surface of the fine sand, and naturally unable to supply nutrients to plants

[0005] In view of the related technologies mentioned above, the inventor believes that in desertification control, planting sandy plants such as Tamarix salix, Salix salix, Haloxylon, etc. makes the plant species in the desert relatively single, and the animals attracted by relatively single plant species are also Relatively simple, it is difficult to form complex communities
