Problems solved by technology

However, the harsh natural conditions of the Taklimakan Desert and strong wind and sand activities pose a huge threat to the long-term safe operation of the Tarim Highway
At present, the mechanical sand control system built simultaneously with the road has basically lost its protective effect, and the sand accumulation on the road is becoming more and more serious

Embodiment 1

[0064] Such as figure 1 As shown, the embodiment of the present application provides a kind of construction method of highway protection forest, comprises the following steps:

[0065] 1) Construction of sand barriers and sand-fixing sealing zone 1 on the windward side of the road,

[0066] The sand barrier sand-fixing enclosure zone 1 includes a mechanical sand barrier and a biological sand barrier, and the biological sand barrier is formed by psammophytes growing on the mechanical sand barrier;

[0067] Wherein, the mechanical sand barrier is a high vertical mechanical sand barrier, made of field waste straw, with a height of 0.3m and a specification of 1m×1m; the width of the sand-fixing sealing zone 1 is 18m, and the sand The periphery of the barrier-fixing sand enclosure zone 1 is provided with a metal mesh fence; the sand plants include sand whips or sand ponies.

[0068] 2) constructing a shrub sand-fixing belt 2 between the highway and the sand-fixing belt 1 of the s...

Embodiment 2

[0096] Such as figure 1 As shown, the embodiment of the present application provides a kind of construction method of highway protection forest, comprises the following steps:

[0097] 1) Construction of sand barriers and sand-fixing sealing zone 1 on the windward side of the road,

[0098] The sand barrier sand-fixing enclosure zone 1 includes a mechanical sand barrier and a biological sand barrier, and the biological sand barrier is formed by psammophytes growing on the mechanical sand barrier;

[0099] Wherein, the mechanical sand barrier is a high vertical mechanical sand barrier, made of field waste straw, with a height of 0.3m and a specification of 1m×1m; the width of the sand-fixing sealing zone 1 is 25m, and the sand The periphery of the barrier-fixing sand enclosure zone 1 is provided with a metal mesh fence; the sand plants include sand whips or sand ponies.

[0100] 2) constructing a shrub sand-fixing belt 2 between the highway and the sand-fixing belt 1 of the s...

Embodiment 3

[0128] Such as figure 1 As shown, in the construction method of highway shelterbelt of one embodiment of the present application, "four belts and two districts system" is designed, which are arranged sequentially from one side of the desert to the direction of the highway. "combined with" structure, and the entire shelterbelt system is set parallel to the road. The following description takes the plant setting on the windward side, that is, the main wind direction side as an example. The design structure and planting order of the plants on the leeward side are the same as those on the main wind direction side, and the width setting It can be smaller than the main wind direction side or half of the main wind direction side.

[0129] 1) Construction of sand barriers and sand-fixing sealing zone 1 on the windward side of the highway,

[0130] The width of described sand barrier sand-fixing enclosure zone 1 is 20m, comprises mechanical sand barrier and biological sand barrier, an...

Abstract

The invention discloses a construction method of a highway protection forest. The method comprises the steps that a sand-protecting barrier sand-fixing seal belt is constructed on the windward side of the highway, a shrub sand-fixing belt is constructed between the highway and the sand-protecting barrier sand-fixing seal belt, an arbor sand-blocking belt is constructed between the highway and the shrub sand-fixing belt, a shrub sand-fixing landscape belt is constructed between the highway and the arbor sand-blocking belt, and two self-propagation seal areas are constructed. According to the construction method of the highway protection forest, through the combination of a mechanical sand-protecting barrier and a biological sand-protecting barrier, the combination of arbors, shrubs and sand-borne plants, the combination of shrubs and sand-borne plants, and the combination of coniferous trees and broadleaf trees, the designed highway protection forest system makes the diversity of the whole system improved and the stability of the system improved, and the reservation of the self-propagation seal area in between the protection forest belts can reinforce the self-renewal capacity of the whole system.

Description

technical field [0001] The invention relates to the technical field of desert control, in particular to a construction method of a road shelterbelt. Background technique [0002] At present, domestic literature reports that the road shelterbelt system constructed is the Tarim highway shelterbelt system located in the Taklamakan Desert. The Tarim Highway is located in the Tarim Basin. It starts from Luntai in the north, reaches Minfeng in the south, and runs through the Taklamakan Desert from north to south. The total length is 522km, of which the section crossing the desert is 446km long. open to traffic. Along the Tarim Highway, there are mainly tall and large composite longitudinal sand ridge landform sections (accounting for about 50% of the desert section of the highway), and the tall and large composite sand ridges and the wide inter-ridges constitute a large-scale landform pattern. The road adopts a mechanical sand control system with front resistance and rear reinfo...
