Description

Technical Field

[0001] The present invention relates to the technical field of agricultural cultivated land slope-to-terrace transformation, and particularly to a method and device for treating erosion ditches in slope-to-terrace transformation, a computer device, and a storage medium. Background Art

[0002] The slope-to-terrace technology has effectively curbed soil erosion in the short term. However, the construction of terraces reshapes the terrain and changes the original runoff concentration path. Runoff is likely to converge at the terrace ridge and form concentrated flow at a relatively low-lying area. Under the long-term scouring of runoff, it is extremely easy to cause damage to the terrace ridge and further form erosion ditches, resulting in the failure of the terrace function. Therefore, when building terraces, how to prevent the formation of ditches is an important issue to be considered. In addition, for the erosion ditches formed after the terraces have been built, how to repair the damaged cultivated land is another problem. Summary of the Invention

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0047] As Figure 1 shown, an embodiment of the present invention discloses a treatment method for erosion ditches in slope conversion to terraced fields, and the method includes the following steps:

[0048] Step S101: Obtain the surface elevation data of the area to be converted from slope to terraced fields to obtain the first terrain data.

[0049] Use a drone to obtain the high-precision surface elevation data of the area to be converted from slope to terraced fields.

[0050] Step S102: Use a preset simulated water erosion model to simulate the runoff path and runoff depth of the terrain corresponding to the first terrain data under rainstorm conditions, and predict the development locations of erosion ditches.

[0051] Based on the terrain data, use the SIMulated water erosion model to simulate the runoff path and runoff depth in the area under rainstorm conditions, and judge the possible development locations of erosion ditches.

[0052] Step S103: Layout an erosion ditch treatment plan for the development locations.

[0053] When designing terraced fields, according to needs, layout an erosion ditch treatment plan for the positions where erosion ditches may be formed.

[0054] Obtain the first terrain data of the area to be converted from slope to terraced fields, use a preset simulated water erosion model to simulate the scouring of the first terrain data by rainstorm weather to form a runoff path and runoff depth, and then predict the locations where erosion ditches may be formed. After that, layout an erosion treatment plan for these locations to solve the problem that erosion ditches are not effectively treated in the prior art.

[0055] In this embodiment, in step S103, it includes:

[0056] While designing the area to be terraced into terraced fields, erosion gully control plans are arranged for the development sites.

[0057] In this plan, when designing the terraced fields, erosion gully control plans are arranged for all development sites.

[0058] In some embodiments, in step S103, it includes:

[0059] After designing the area to be terraced into terraced fields, obtain the rainstorm conditions in the area where the terraced fields are located;

[0060] If there is a rainstorm in the area where the terraced fields are located, then monitor the terraced fields after the rainstorm;

[0061] According to the monitored terraced field data, judge whether the development site has developed into a gully or has a tendency to develop into a gully;

[0062] If so, mark the development site to obtain the first site to be treated;

[0063] Arrange an erosion gully control plan for the first site to be treated.

[0064] In this plan, erosion gully control plans are not arranged for all development sites. Instead, after designing the terraced fields and after the exposure, monitor the terraced fields to judge whether the development points have developed into gullies or have a tendency to develop into gullies, and arrange erosion gully control plans for these development points.

[0065] In some embodiments, after the step of obtaining the rainstorm conditions in the area where the terraced fields are located, it includes:

[0066] If the duration without rainstorm in the area where the terraced fields are located is greater than the preset duration, then trigger the event of monitoring the terraced fields;

[0067] According to the monitored terraced field data, judge whether the development site has developed into a gully or has a tendency to develop into a gully;

[0068] If so, mark the development site to obtain the second site to be treated;

[0069] Arrange an erosion gully control plan for the second site to be treated.

[0070] If the terraced fields do not have a rainstorm for more than the preset duration, then it is also necessary to monitor the terraced fields. Specifically, the preset duration is 3 months. Monitor the terraced fields to judge whether the development points have developed into gullies or have a tendency to develop into gullies, and arrange erosion gully control plans for these development points.

[0071] In some embodiments, after the step of designing terraced fields in the area to be terraced and arranging an erosion gully treatment plan for the development site, the following steps are included:

[0072] After a preset first time period, monitor the terraced fields;

[0073] Based on the monitored terraced field data, determine whether the development site has developed into a gully or has a tendency to develop into a gully;

[0074] If so, mark the development site to obtain a third site to be treated;

[0075] Redesign an erosion gully treatment plan for the third site to be treated.

[0076] Although an erosion gully treatment plan has been arranged for the development site, there may be a situation of failure. Therefore, it is necessary to further monitor whether the erosion gully treatment plan arranged at the development point fails. If it fails, it needs to be redesigned.

[0077] Specifically, the preset first time period is 12 months.

[0078] In this embodiment, the erosion gully treatment plan includes:

[0079] Trim the gully bottom into a rectangular shape, with a trimming depth of 50 - 100 cm, and place the trimmed soil on both sides of the gully bank;

[0080] Place multiple perforated threaded pipes with a diameter of 10 - 30 cm wrapped with geotextiles along the gully channel direction at the gully bottom;

[0081] Stack straw bales in the gully channel and press them on the threaded pipes;

[0082] Spread the soil piled on both sides of the gully bank on the straw bales.

[0083] For the bottom and slopes of the gully, first use an excavator to trim the bottom of the gully into a roughly rectangular shape with a trimming depth of about 50 - 100 cm. The excavated soil is placed on both sides of the gully bank. After wrapping the geotextile around the perforated threaded pipe with a diameter of 20 cm, place it along the gully channel at the bottom of the gully (the number of threaded pipes laid: determine the water infiltration rate of the soil and the infiltration rate of the infiltration well, and calculate according to the storm statistical data of the region and the runoff depth at the confluence combined with the hydrological model). Then stack the packed square or cylindrical straw bales (density > 230 kg / m3) in the gully channel, pressing them on top of the threaded pipe. The stacking height depends on the actual gully channel. After stacking, spread the soil piled on both sides on top of the straw. The soil layer thickness can be about 50 cm. The vertical distance from the bottom of the gully after covering the soil to the gully bank should be kept at 1.5 m. In this way, the originally steep gully bank slope length becomes shorter, the gully bank is more stable, and the excess soil is spread on both sides of the gully slope, reducing the slope of the gully bank (gully slope) to below 35° further, so as to achieve the purpose of stabilizing the gully bank without destroying the cultivated land by cutting both sides of the gully bank.

[0084] In this embodiment, the erosion gully treatment plan includes:

[0085] Install a composite infiltration well at the junction of the gully channel and the terrace ridge.

[0086] Install a composite infiltration well at the junction of the gully channel and the terrace ridge. This is the main place where the runoff converges. It is necessary to install an infiltration well to accelerate the infiltration speed of the runoff. It should be noted that the height of the infiltration well should be flush with or slightly higher than the terrace ridge, which can effectively intercept the runoff, extend the infiltration time of the runoff, and increase the infiltration volume.

[0087] Furthermore, the installation of the composite infiltration well includes:

[0088] Install two retaining walls with straw bales in the gully channel, and place wire mesh and geotextile inside the retaining walls. The distance between the two retaining walls is 1.5 - 3 m;

[0089] Place a perforated threaded vertical pipe wrapped with geotextile between the two retaining walls, and tie the upward pipe orifice with wire mesh and geotextile;

[0090] Fill the space between the two retaining walls with stones with a diameter of 10 - 20 cm to a height of 10 - 30 cm from the top of the perforated threaded vertical pipe;

[0091] Cover the wire mesh and geotextile, and then fill with coarse sand until it is flush with the terrace ridge.

[0092] The specific method for arranging infiltration wells is as follows: In the cross-section of the gully, two retaining walls are first arranged with straw bales at the upper and lower parts respectively. The inner distance between the retaining walls is about 2m. Then, wire meshes and geotextiles are placed, and a threaded pipe with holes wrapped with geotextile is put in (at the upward opening of the vertical pipe, it is necessary to tie it with wire meshes and geotextiles to prevent sediment and stones from falling into it, causing blockage and resulting in the failure of the vertical pipe). Stones with a diameter of about 15cm are filled to about 20cm away from the top, the wire meshes and geotextiles are closed, and then coarse sand is filled in the top 20cm to prevent the plowshare from being damaged during tillage. After all the work is completed, the infiltration well is flush with the terrace ridge. The runoff on both sides of the ridge enters the threaded pipe after infiltrating through the coarse sand layer and straw layer, and is discharged from the gully in the form of subsurface runoff, avoiding scouring and erosion caused by flowing on the ground surface.

[0093] As Figure 2 shown, the present invention also proposes a treatment device 1 for slope-to-terrace erosion gullies. The device 1 includes an acquisition module 11, a prediction module 12, and a treatment module 13.

[0094] The acquisition module 11 is used to acquire the surface elevation data of the area to be slope-to-terraced to obtain the first topographic data.

[0095] The high-precision surface elevation data of the area to be slope-to-terraced is acquired by using an unmanned aerial vehicle.

[0096] The prediction module 12 is used to simulate the runoff path and runoff depth of the terrain corresponding to the first topographic data under rainstorm conditions by using a preset simulated water erosion model, and predict the development locations of erosion gullies.

[0097] Based on the topographic data, the runoff path and runoff depth in the region under rainstorm conditions are simulated by using the SIMulated water erosion model to judge the possible development locations of erosion gullies.

[0098] The treatment module 13 is used to arrange an erosion gully treatment plan for the development locations.

[0099] When designing terraces, according to needs, an erosion gully treatment plan is arranged for the positions where erosion gullies may be formed.

[0100] The first topographic data of the area to be slope-to-terraced is acquired, and the first topographic data is simulated by using a preset simulated water erosion model under rainstorm weather for scouring to form a runoff path and runoff depth, and then the locations where erosion gullies may be formed are predicted. After that, an erosion treatment plan is arranged for these locations to solve the problem that erosion gullies are not effectively treated in the prior art.

[0101] In this embodiment, the treatment module 13 includes:

[0102] The first sub-governance module is used to arrange an erosion ditch governance plan for the development site while designing the area to be terraced into terraced fields.

[0103] In this plan, when designing terraced fields, an erosion ditch governance plan is arranged for each development site.

[0104] In some embodiments, the governance module 13 includes:

[0105] The first sub-acquisition module is used to obtain the heavy rain situation in the area where the terraced fields are located after the area to be terraced is designed into terraced fields;

[0106] The first sub-monitoring module is used to monitor the terraced fields after the heavy rain if there is heavy rain in the area where the terraced fields are located;

[0107] The first sub-judgment module is used to judge whether the development site has developed into a gully or has a tendency to develop into a gully according to the monitored terraced field data;

[0108] The first sub-marking module is used to mark the development site if so, to obtain the first site to be governed;

[0109] The second sub-governance module is used to arrange an erosion ditch governance plan for the first site to be governed.

[0110] In this plan, an erosion ditch governance plan is not arranged for all development sites. Instead, after designing the terraced fields and after the exposure, the terraced fields are monitored to judge whether the development points have developed into gullies or have a tendency to develop into gullies, and an erosion ditch governance plan is arranged for these development points.

[0111] In some embodiments, the device 1 includes:

[0112] The first sub-trigger module is used to trigger an event of monitoring the terraced fields if the duration when there is no heavy rain in the area where the terraced fields are located is greater than a preset duration;

[0113] The second sub-judgment module is used to judge whether the development site has developed into a gully or has a tendency to develop into a gully according to the monitored terraced field data;

[0114] The second sub-marking module is used to mark the development site if so, to obtain the second site to be governed;

[0115] The third sub-governance module is used to arrange an erosion ditch governance plan for the second site to be governed.

[0116] If the terraces do not have heavy rain for a preset period of time, they also need to be monitored. Specifically, the preset period is 3 months. The terraces are monitored to determine whether the development points have developed into gullies or have the tendency to develop into gullies, and gully erosion control plans are deployed for these development points.

[0117] In some embodiments, the apparatus 1 comprises:

[0118] A second sub-monitoring module is used to monitor the terraced field after a preset first time period;

[0119] The third sub-judgment module is used to judge whether the development site has developed into a ditch or has a tendency to develop into a ditch according to the monitored terrace data;

[0120] A third sub-marking module is used for marking the development site to obtain a third site to be managed;

[0121] The fourth sub-management module is used to re-arrange the gully erosion management plan for the third location to be managed.

[0122] Although gully erosion control schemes have been deployed at the development sites, there may be cases where the schemes fail. Therefore, it is necessary to further monitor whether the gully erosion control schemes deployed at the development sites fail. If they fail, they need to be re-deployed.

[0123] Specifically, the first period is preset to be 12 months.

[0124] In this embodiment, the gully erosion control scheme includes:

[0125] The ditch bottom is trimmed into a rectangular shape with a trimming depth of 50-100cm, and the trimmed soil is placed on the ditch banks on both sides;

[0126] Wrap multiple threaded pipes with holes of 10-30cm in diameter with geotextiles and place them at the bottom of the ditch along the direction of the ditch;

[0127] Stack the straw bales in the trench and press them on the threaded pipes;

[0128] Spread the soil piled on both sides of the ditch evenly on the straw bales.

[0129] For the bottom and slopes of the gully, first use an excavator to trim the gully bottom into a roughly rectangular shape with a trimming depth of about 50 - 100 cm. The excavated soil is placed on both sides of the gully bank. After wrapping the geotextile around the perforated threaded pipe with a diameter of 20 cm, place it along the gully channel direction at the gully bottom (the number of threaded pipes laid: measure the water infiltration rate of the soil and the infiltration rate of the infiltration well, and calculate according to the storm statistical data of the region and the runoff depth at the confluence combined with the hydrological model). Then stack the packed square or cylindrical straw bales (density > 230 kg / m³) in the gully channel, pressing them on top of the threaded pipe. The stacking height depends on the actual gully channel. After stacking, spread the soil piled on both sides on top of the straw. The soil layer thickness can be about 50 cm. The vertical distance from the covered gully bottom to the gully bank should be kept at 1.5 m. In this way, the originally steep gully bank slope length becomes shorter, the gully bank is more stable, and the excess soil is spread on both sides of the gully slope, reducing the slope of the gully bank (gully slope) to below 35° further, so as to achieve the purpose of stabilizing the gully bank without cutting the two sides of the gully bank and damaging the cultivated land.

[0130] In this embodiment, the erosion gully treatment plan includes:

[0131] Layout composite infiltration wells at the junction of the gully channel and the terrace ridge.

[0132] Layout composite infiltration wells at the junction of the gully channel and the terrace ridge. This is the main place where runoff converges. It is necessary to layout infiltration wells to accelerate the infiltration speed of runoff. It should be noted that the height of the infiltration well should be flush with or slightly higher than the terrace ridge, which can effectively intercept runoff, extend the infiltration time of runoff, and increase the infiltration volume.

[0133] Further, the layout of the composite infiltration well includes:

[0134] Layout two retaining walls with straw bales in the gully channel, and place wire mesh and geotextile inside the retaining walls. The distance between the two retaining walls is 1.5 - 3 m;

[0135] Place a perforated threaded vertical pipe wrapped with geotextile between the two retaining walls, and tie the upward pipe orifice with wire mesh and geotextile;

[0136] Fill the space between the two retaining walls with stones with a diameter of 10 - 20 cm to a height of 10 - 30 cm from the top of the perforated threaded vertical pipe;

[0137] Cover the wire mesh and geotextile, and then fill with coarse sand until it is flush with the terrace ridge.

[0138] The specific method for arranging infiltration wells is as follows: In the cross-section of the ditch, two retaining walls are first arranged with straw bales at the upper and lower parts respectively. The distance between the retaining walls is about 2 m. Then, wire meshes and geotextiles are placed. A threaded pipe with holes wrapped with geotextiles is put in (at the upward opening of the vertical pipe, it is necessary to tie it with wire meshes and geotextiles to prevent sediment and stones from falling into it, causing blockage and resulting in the failure of the vertical pipe). Stones with a diameter of about 15 cm are filled to about 20 cm from the top. The wire meshes and geotextiles are closed. Then, coarse sand is filled in the top 20 cm to prevent the plowshare from being damaged during tillage. After all the work is completed, the infiltration well is flush with the terrace ridge. The runoff on both sides of the ridge enters the threaded pipe after infiltration through the coarse sand layer and straw layer, and is discharged from the ditch in the form of subsurface runoff, avoiding scouring and erosion caused by surface flow.
