Vegetation bags, artificial bush sand piles, sand blocking and fixing belt and construction method and application thereof

Abstract

The invention discloses vegetation bags, artificial bush sand piles, a sand blocking and fixing belt and a construction method and application thereof. The method for establishing the sand blocking and fixing belt of the bush sand piles based on the vegetation bags comprises the following steps that soil is taken locally and piled into conical mounds; a plurality of vegetation bags are neatly stacked on the surfaces of the conical mounds along contour lines; sand fixing bushes are planted in all the vegetation bags to form the artificial bush sand piles; and a plurality of artificial bush sandpiles are arranged in multiple rows in a delta shape to form the sand blocking and fixing belt. According to the method for establishing the sand blocking and fixing belt based on the vegetation bags, the forming process of the bush sand piles is shortened to one year from several years to dozens of years in the nature; and meanwhile, due to the fact that the bush sand piles have the good water storage and conservation characteristics, the bush sand piles are established through the artificial and natural combined mode to form the sand blocking and fixing belt, and sustainable sand control under the natural rain-fed condition is achieved.

Description

technical field [0001] The invention belongs to the technical field of ecological management, and in particular relates to a planting bag, an artificial shrub pile, a sand-resistance and sand-fixation belt, and a construction method and application thereof. Background technique [0002] Shrub-sand piles are aeolian biogeomorphic types formed in arid, semi-arid, sub-humid desert regions and sandy coastal zones where wind-blown sand particles are accumulated in and around the shrubs due to wind-blown sand flows being blocked by shrubs. Types include Caragana, Tamarix, Nitraria, Artemisia, etc. These shrub mounds play a very important role in windbreak and sand fixation, protection of species diversity and maintenance of regional ecological balance. With the continuous deepening of the research on aeolian landform and desertification process, the research on shrub sand piles has received more and more attention at home and abroad, but mainly focuses on the morphological charac...

AI Technical Summary

Problems solved by technology

At present, there are few studies on the regeneration mechanism of shrub mounds, and the artificial assisted conservation measures and methods for shrub mounds are limited to relatively simple levels such as fencing, grazing, or artificial stubble. There is still a gap in related research
