Strip greening method of arid and semi-arid lands

Abstract

The invention provides a strip greening method of arid and semi-arid lands. When the sloping fields of the arid and semi-arid lands are greened, the greening area is divided into a rain collection belt and a green belt, wherein greening vegetation is planted on the green belt, and a plastic film is covered on the rain collection belt; the ratio of the rain collection belt and the green belt can be solved by a formula, wherein x is annual average rainfall, M is the width of the rain collection belt, and L is the width of the green belt. The invention can improve the greening effects in the arid and semi-arid lands, controls soil degradation speed, improves local ecological environment and improves the carbon sink ability of the green belt. Meanwhile, the invention has the advantages of low forestation cost and later-stage maintenance cost and the like, and has favorable ecological, social and economic value and wide market space and application prospects.

Description

technical field The invention belongs to the field of environmental greening and relates to an environmental greening method in arid and semi-arid areas. Background technique When carrying out environmental greening, the traditional greening method is to evenly plant green plants and trees. Practice shows that traditional greening methods are not ideal in arid and semi-arid areas, and may achieve certain results in the short term. But in the long run, the survival rate of green vegetation is generally low. Even if they can survive, they will grow slowly under the limitation of available water resources and become "little old trees". In individual areas, it even leads to the decline of groundwater, causing serious damage to the local ecological environment. At present, some existing improved methods, such as container seedling method, alien soil afforestation method, embedding seedling overwintering method, etc., either treat the symptoms but not the root cause, or are cost...

AI Technical Summary

Problems solved by technology

At present, some existing improved methods, such as container seedling method, alien soil afforestation method, earth-burying seedling overwintering method, etc., either treat the symptoms but not the root cause, or are costly, and are not suitable for widespread promotion.

From an ecological point of view, the biggest limitation of traditional greening methods and their improvement measures is that they only focus on the growth of individual plants, while ignoring the ecological laws at the level of plant populations.
