Problems solved by technology

Our country's desertification prevention and control work has achieved remarkable results that have attracted the attention of the world. As far as the country is concerned, the speed of desertification in some sandy areas has slowed down, and the situation of desertification has been initially curbed, but the situation of desertification has not fundamentally changed. The situation facing desertification control work is still very severe. There are still 1.7311 million square kilometers of desertifie

Embodiment Construction

[0017] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0018] The sandy land remediation method in arid areas, the windward side of the farmland is successively provided with a frontal wind-resistant sand forest belt, a sand-fixing forest belt, a living sand barrier sand-blocking belt, and a sand sealing belt for afforestation and grass cultivation. The wind-resistant sand forest belt is set at the front edge of the farmland. The width of the wind-resistant sand forest belt is 5.5m. Inside the front wind-resistant sand forest belt are planted Xinjiang poplar, Elaeagnus syrifolia, and multi-branched tamarisk. 0.5m×1m, two rows and one belt, with a belt spacing of 1m; this structure forms a three-dimensional configuration from low to high, from dense to sparse, which can effectively prevent the wind an...

Abstract

The invention discloses a desertificated land treatment method for a windy and sandy area in an arid desert. A four-zone integrated wind prevention and sand stabilization forest system consisting of a wind prevention and sand resistance forest zone, a sand stabilization forest zone, a plant living sand-barrier sand resistance zone and a sand-sealing afforestation and lawn cultivation zone is arranged on the windward side on the front rim of a farmland. An artificial wind prevention and sand stabilization style combining resistance, stabilization, secondary resistance and sealing is formed on the rim of a new oasis, so that quicksand around the new oasis can be effectively prevented from invading the farmlands and villages; meanwhile, sand impact and sand cutting, which are caused by wind-sand flow which passes by, to crops are alleviated; the desertificated land treatment method has an obvious protection effect, is novel in design, is an extremely good innovation scheme and has an extremely good market popularization prospect.

Description

technical field [0001] The invention relates to the technical field of desertification prevention and control, in particular to a method for improving sandy land in arid desert sandstorm areas. Background technique [0002] Desertification has become an extremely important environmental and socio-economic problem in today's world, threatening the survival and development of human beings. Desertification is mainly caused by the interaction between unreasonable human activities and fragile ecological environment, which is manifested as the decline of land productivity, loss of land resources, and land degradation similar to desert landscape on the surface. my country is the country with the largest desertification and sandification area in the world. Our country's desertification prevention and control work has achieved remarkable results that have attracted the attention of the world. As far as the country is concerned, the speed of desertification in some sandy areas has sl...
