Sand-fixing governance and planting integration method for sandy land

Abstract

The invention provides a sand-fixing governance and planting integration method for sandy land. The method comprises the following steps of S1, arranging a plurality of sand blocking walls in a main wind direction and reserving a certain space between every two adjacent sand blocking walls; S2, arranging a sand-fixing propulsion area on the sides, in the main wind direction, of the sand blocking walls on a leeward side; S3, arranging a planting area at a certain distance from the sand blocking walls on the leeward side, planting high herbaceous sand-fixing plants or sand-fixing shrubs in the planting area, and watering and irrigating the plants and the shrubs with clean water; S4, arranging a planting buffer protection area between the inner side of the leeward of the sand blocking walls and the planting area, planting short sand-fixing plants in the planting buffer protection area, and watering and irrigating the plants with the clean water, wherein the planting buffer protection areais changed into a planting area after governance. By means of the method, wind and sand can be effectively prevented from invading and burying roads and railways, adaptive planting transformation ofthe sandy land around the roads can also be achieved, local materials are adopted, the cost is low, and simple construction is facilitated.

Description

technical field [0001] The invention relates to an integrated method for sand fixation treatment and planting in desertified land, belonging to the technical field of environmental treatment. Background technique [0002] In order to cooperate with the country's overall strategy of western development, it is necessary to vigorously carry out infrastructure construction. Transportation is an important lifeline for the development of the regional economy. The country has extensively built road transportation and railway transportation in the western region to open up the regional economic bloodline. The traffic road network often needs to pass through areas with severe desertification. In the sandy land area, the road is often buried under the intrusion of wind and sand, and the location of the buried area is uncertain. The traffic efficiency of the railway and the long-term sand erosion damage to the roadbed are also great, seriously affecting the life of the road. [0003] ...

AI Technical Summary

Problems solved by technology

The traffic road network often needs to pass through areas with severe desertification. In sandy soil areas, roads are often buried under wind and sand intrusion, and the location of the buried area is uncertain. Manual excavation and cleaning are often required to clear the road surface, which seriously affects roads, especially The traffic efficiency of the railway, and the damage to the subgrade due to long-term wind and sand erosion is also great, seriously affecting the life of the road

[0003] At present, in practical applications, construction parties often use brick-laying walls as sand-retaining walls to block wind and sand, and sandy land cannot provide corresponding building materials, which need to be transported from other places. The transportation cost is extremely high, and after a certain After the wind and sand erosion of time, the effect of the sand retaining wall decreases, and there is no way to meet the requirements of sand retaining well
