Stony desertification region vegetation ecological system and reestablishing method thereof

Abstract

The invention discloses a stony desertification region vegetation ecological system and a reestablishing method thereof. The vegetation ecological system is high in water storage capacity, plants grow easily, and the vegetation ecological system in the stony desertification region can be reestablished fast. The vegetation ecological system comprises a ground, multiple arbor planting matrixes and multiple shrub growing matrixes are arranged on the ground, a herbal growth carrier is laid in the other regions of the ground, arbors are planted in the arbor planting matrixes, shrubs are planted in the shrub growing matrixes, and herbal plants are planted in the herbal growth carrier. The reestablishing method includes the following steps that the arbor planting matrixes are prefabricated; planting matrix embedding holes are dug, holes for inserting water absorbing roots are drilled, the water absorbing roots are inserted into the holes, the arbor planting matrixes are placed, and arbor saplings are planted; the shrub growing matrixes are formed through a blast method, and the herbal growth carrier is laid; after deadwood fallen leaves, dinas soil mass generated by overland runoff are converged in the shrub growing matrixes and attached to the surface of the herbal growth carrier, and then shrub and herbal plant seeds are manually broadcast.

Description

Technical field [0001] The patent of the invention belongs to the field of vegetation restoration in rocky desertification areas, and in particular relates to a vegetation ecosystem in rocky desertification areas and a reconstruction method thereof. Background technique [0002] Rocky desertification is a global environmental geological problem and ecological degradation problem, which mainly occurs in limestone areas and is called "earth cancer" internationally. Vegetation ecosystems in rocky desertification areas are fragile. Vegetation is destroyed under conditions of human engineering activities, overgrazing, and extreme arid climates. The ecosystem is rapidly deteriorating, manifested by poor vegetation coverage, serious soil erosion, poor water conservation, and large area of ​​bedrock Bareness, reduced land productivity, and a desertified landscape. China is the most severely rocky desertification country in the world. As of the end of 2011, the total area of ​​rocky dese...

AI Technical Summary

Problems solved by technology

Measures such as closing mountains for afforestation are used to restore the ecological environment of degraded rocky desertification areas. According to the natural evolution law of ecosystems, a vegetation ecosystem in a rocky area follows the reconstruction model of low-level lichen vegetation → ephemeral herb fabric → low shrubs → arbors. This process The time required is relatively short, ranging from decades to thousands of years, which has no practical significance for effectively improving the living environment and sustainable economic development in rocky desertification areas

Following the principles of artificial seeding and natural vegetation recovery, the survival rate of plants is low, the effect of afforestation is poor, and the recovery time of the ecosystem is long

It is difficult to restore vegetation in rocky desertification areas. The fundamental reason is that the soil in these areas is barren and shallow, and the surface runoff is fast and the water storage capacity is low, which easily causes water shortage and drought, which makes it difficult for plants to grow.
