Embodiment 1

[0028] The land for desertification control consists of multiple patches 1 , multiple corridors 2 and the use of corridors to connect these patches to form a larger range-matrix 3 .

[0029] Each patch of multiple patches 1 is 400m 2 , the patch arrangement direction is perpendicular to the expansion direction of the desertified land and the dominant wind direction, so as to achieve the effect of windbreak and sand fixation.

[0030] Several ditches 4 are opened on each of the multiple patches 1, the ditch depth is 30cm, the ditch width is 20cm, the ditch length is 2m, and the distance between ditches is 4m, and the filling in the ditch is a mixture of soil and cow dung manure 6 .

[0031] The shape of the ditch on each of the multiple plaques 1 is square.

[0032] Several ditches are opened on each corridor of the plurality of corridors 2, the ditch depth is 30cm, the ditch width is 20m, and the ditch length is 2m.

[0033] The governance method of desertification control ...

Embodiment 2

[0038] The land for desertification control consists of multiple patches 1 , multiple corridors 2 and the use of corridors to connect these patches to form a larger range-matrix 3 .

[0039] Each patch of multiple patches 1 is 10000m 2 , the patch arrangement direction is perpendicular to the expansion direction of the desertified land and the dominant wind direction, so as to achieve the effect of windbreak and sand fixation.

[0040] Several ditches 4 are opened on each of the multiple patches 1, the ditch depth is 40cm, the ditch width is 40cm, the ditch length is 10m, and the distance between ditches is 4m to 8m, and the filling materials in the ditch are soil and cow manure Mixture, and require the direction of the ditch to be perpendicular to the dominant direction of winter and spring.

[0041] The shape of the grooves on each of the multiple plaques 1 is trapezoidal.

[0042] Several ditches 5 are opened on each corridor of the plurality of corridors 2, the ditch dep...

Abstract

The invention discloses desertification control land and a control method thereof. The control method is characterized in that positions of patches (1) and corridors (2) are selected, and the patches (1) are connected together through the corridors (2) to form a matrix (3); the patch-corridor-matrix is a whole which is in continuous connection and development in space, and is used for breaking up the large-area desertification land into parts when being applied to the desertification control land, so as to achieve the control mode of letting one unit guide a whole area, and the distance between every two patches is determined via the size, expansion rate and control cost of the desertification land; a plurality of grooves (4) and (5) are respectively formed in each patch (1) and each corridor (2) and are filled with a mixture (6) of soil and cow manure; grass seeds (8) are sowed in the grooves, and tree seeds (9) are in root cutting or planted in the grooves, and then sand (7) is spread and laid on the surfaces of the grooves sowed with the grass seeds; the arrangement direction of the grooves is required to be vertical to the direction of the dominant wind in winter and spring, which is more conducive to the control effect.

Description

Technical field: [0001] The invention relates to a desertification control land and a control method thereof, and belongs to the field of reconstruction and recovery of desertification land ecosystems. Background technique [0002] Desertified land is rapidly engulfing large tracts of land, exacerbating the degradation of the ecological environment, the rapid decline of species diversity, and at the same time posing a great threat to agricultural and animal husbandry production. The control methods for desertified land mainly include fencing, weaving sand barriers, planting sandy tree species and sowing grass seeds. These methods are not carried out alone, but are often carried out in combination. Fences are used to enclose the treatment area first, and then weaving sand barriers, planting tree seeds and sowing grass seeds. Use vegetation to gradually improve the habitat of desertified land, so as to achieve the effect of governance. [0003] However, the extreme climatic...
