[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0030] The following is combined Figure 1 The present invention describes a method for quantitatively determining wind-blown sand entering gullies on slopes. This method is applicable to the monitoring and calculation of the quantitative wind-blown sand entering gullies on slopes. The execution subject of this method can be an electronic device or a device for quantitatively determining wind-blown sand entering gullies on slopes installed in the electronic device. This device can be implemented through software, hardware, or a combination of both. Figure 1 This is a flowchart illustrating the method for quantitatively determining wind-blown sand inflow into gullies on slopes provided by the present invention. Figure 1 As shown, the method includes the following steps 101, 102 and 103.
[0031] Step 101: Obtain the slope area of the slope to be determined.
[0032] In this step, the slope area refers to the area of the slope surface enclosed by the slope gully edge line to the main channel of the slope to be determined. The slope gully edge line is a relatively clear boundary of the slope in a small watershed in nature, used to distinguish the gentler upper slope and the steeper channel of the slope to be determined. The main channel is specifically the bottom water-flowing channel of the small watershed for the slope to be determined. The main channel of a small watershed generally has a certain width. If it is necessary to measure the wind-blown sand entering the gully on the left (right) bank slope of the small watershed, the sand collector should be placed at the foot of the left (right) bank slope, not at the center of the main channel. This embodiment does not impose this limitation.
[0033] Among them, the slope to be determined can be a slope that is susceptible to wind erosion, including natural or artificially formed slopes, such as the slopes of ditches or rivers, and the slopes of production and construction projects. The land use of the slope is mainly sandy land, desertified land, and bare land, etc. This embodiment does not limit this.
[0034] The specific slope to be determined refers to the area from the edge of the gully to the bottom of the gully. The surface of this area is generally composed of sandy land, desertified land, or bare soil. Under the combined influence of wind and gravity, surface materials on the slope are easily transported downwards, resulting in soil erosion. Desertified slopes are common in nature and widely distributed in arid and semi-arid regions, where wind erosion causes sand to enter the gully. In addition, various types of slopes are formed by production and construction projects, such as slag heap slopes, highway slopes, and railway slopes, which are also prone to wind erosion in arid and semi-arid regions. This embodiment does not limit the scope of these slopes.
[0035] Specifically, obtain the slope area of the slope to be determined. The slope area refers to the area of the slope surface from the edge of the ditch to the main channel, and the unit is square meters.
[0036] For example, Figure 2 This is one of the schematic diagrams of the slope provided by the present invention, such as... Figure 2 As shown, the main channel of the slope to be determined runs in a northeast-southwest direction. The slope to be determined includes the gully edge, the main channel, and the watershed. The watershed is the main boundary dividing two adjacent slopes. The slope area of the slope to be determined is mainly indicated by... Figure 2 The total area from the two ditch edges to the main ditch. Figure 3 This is the second schematic diagram of the slope provided by the present invention, as shown below. Figure 3 As shown, the main channel of the slope to be determined runs in a northwest-southeast direction. The slope to be determined includes the gully edge, the main channel, and the watershed. The watershed is the main boundary dividing two adjacent slopes. The slope area of the slope to be determined is mainly indicated by... Figure 3 The total area from the two edge lines of the ditch to the main channel is not limited in this embodiment.
[0037] Step 102: Obtain the mass of sand transported by all sand collectors on the main channel of the slope to be determined, and determine the distance between sand collectors on the main channel.
[0038] In this step, the mass of the transported sand is collected by a sand collector. The measurement area of the main channel of the slope to be determined includes the measurement start point, the measurement end point, and at least two sand collectors. The distance between the sand collectors refers to the distance between the measurement start point, the measurement end point, and any two of the at least two sand collectors.
[0039] The sand collector is typically a BSNE (Big Spring Number Eight) sand collector. BSNEs can collect suspended particles under different wind conditions. Each sand collection box of a BSNE sand collector has an inlet length of 5 cm and a width of 2 cm, and the sand collection efficiency is around 90%. Generally, the sand collection boxes of the BSNE sand collector are fixed to a fixed rod according to different integration heights and then fixed to a wind vane that can rotate around an axis, forming a sand collector system that allows for observation of the sand transport flux at the integration height. BSNE sand collectors are characterized by simple construction, convenient operation, the ability to always point the sand inlet towards the erosion wind direction, and the ability to collect sand samples at different heights at a single point. They can also be used for long-term field wind and sand observations; however, this embodiment does not limit its application.
[0040] The deployment of sediment collectors on the main channel of the slope is primarily based on extracting the gully edge line and channel of the slope according to the topographic features of the small watershed. Sediment collectors are deployed along the main channel of the small watershed at the toe of the slope. Specific deployment factors include: 1) maintaining a consistent distance between adjacent sediment collectors on the main channel; 2) deploying sediment collectors at points where the main channel's shape changes to reflect the natural variation in sediment transport flux; 3) considering micro-topographical variations during deployment; and 4) to minimize the potential impact of channel water flow on the aeolian sand collection of the sediment collectors in the main channel, the sediment collectors should be deployed at a certain height at the toe of the slope before deployment. Additionally, depending on operational needs, weather stations capable of monitoring wind speed and direction can be deployed at suitable locations around the slope. The recommended wind direction monitoring range is 0-360 degrees, but this embodiment does not impose such a limitation.
[0041] Specifically, after the sand collectors are set up on the main channel of the slope, the corresponding mass of sand transported is obtained based on all the sand collectors set up on the main channel of the slope, and the distance between the sand collectors on the main channel is determined.
[0042] For example, the deployment of a sand collector mainly includes two steps: sand collector installation and anemometer installation. First, a suitable ditch or river slope, or the slope of the construction project, is selected. The placement of the sand collector is determined at the bottom of the ditch based on the main ditch's alignment and the toe of the slope at a certain height from the main ditch. The distance between adjacent sand collectors is then determined reasonably based on the actual conditions of the main ditch. A cylindrical pit approximately 50 cm deep and 10 cm larger in diameter than the base of the fixing rod is excavated at the determined location for burying the sand collector. Each sand collector set consists of four parts: a fixing rod, a base, a sand collection box, and a box holder. The base is designed with screw holes that match the anchor bolts. The bottom of the fixing rod is inserted into the base. The length of the fixing rod is generally 2.1-2.6 meters (determined according to the deployment height of the sand collection box), with approximately 0.5 meters buried vertically underground. Each sand collector set is equipped with three fiber ropes to increase its stability. Determine the installation height of the sand collection box, and fix the box holder at the corresponding height of the sand collector. The sand collection box should then be placed on the box holder. After completing the above steps, the quantitative determination of wind-blown sand entering the gully on the slope to be determined can begin, i.e., the observation of wind erosion events on the slope to be determined. Then, select suitable locations around the slope to deploy meteorological stations that can monitor wind speed and direction, and install meteorological stations that can measure and automatically record wind speed and direction data. It is recommended that the height of the wind speed sensor be designed to be 1 meter and 2 meters, and the recording interval be 2 minutes. After completing the above steps, the observation of wind erosion events can begin. This embodiment does not impose any limitations on this.
[0043] Sample Collection: Following each wind erosion event, wind-eroded material was collected from each sand collection box. During collection, the sand collection box, fixed to the tray, was removed and brought back to a windless indoor environment. The wind-eroded material in the collection box was carefully swept into a pre-weighed and labeled self-sealing bag, and weighed again. The difference between the two weighings is the mass of wind-eroded material collected from that sand collection box. A balance with a weight of 0.01% is recommended for weighing.
[0044] In one specific embodiment, obtaining the mass of sand transported by all sand collectors on the main channel of the slope to be determined includes: obtaining the wind erosion amount collected by each sand collector in each segment of the integration height; wherein the integration height is divided into at least two segments; summing all the wind erosion amounts collected by each sand collector in each segment of the integration height to determine the mass of sand transported by each sand collector.
[0045] In this step, for each wind erosion event, the mass of wind-eroded material in the sand collection boxes at different heights of each sand collector is collected and weighed to obtain the mass of sand transported by each sand collector.
[0046] In practice, four different heights are typically set for the integration height. For example, if the height of the sand inlet of each sand collection box is 5 cm, then the height of 0-5 cm is defined as the first segment of the integration height, the height of 5-10 cm is defined as the second segment, and so on. This embodiment does not limit this.
[0047] Specifically, for each sand collector, the integration height is divided into multiple segments, each containing a sand collection box. The wind erosion amount in the sand collection box of each segment of the integration height is obtained. Then, all the wind erosion amounts collected by each sand collector in each segment of the integration height are summed to determine the mass of sand transported by each sand collector.
[0048] Furthermore, in actual operation, in order to avoid the impact of precipitation on subsequent sand collection, the sand collector should be placed on a slope at a certain distance from the bottom. This embodiment does not impose such a limitation.
[0049] In one specific embodiment, obtaining the wind erosion amount collected by each sand collector at each segment of the integration height includes: obtaining the measured wind erosion amount of each sand collector at a set segment of the integration height; determining the wind erosion amount coefficient based on the measured wind erosion amount; and determining the wind erosion amount collected by each sand collector at each segment of the integration height based on the wind erosion amount coefficient; wherein, the wind erosion amount... ,in, and All are wind erosion coefficients. The first part representing the integral height part, The first part representing the integral height The amount of wind erosion in the section.
[0050] Specifically, the measured wind erosion amount of each sand collector in a set section at the integration height is obtained; the wind erosion coefficient is determined based on the measured wind erosion amount; and the wind erosion amount collected by each sand collector in each section at the integration height is determined by inverse calculation based on the wind erosion coefficient.
[0051] For example, if the upper limit of the integration height is 2 meters, and the integration height is divided into forty segments, then when determining the wind erosion amount collected by a sand collector in each segment of the integration height, the segments are first designated as segments one through four. After obtaining the measured wind erosion amounts for segments one through four, the wind erosion coefficient is calculated based on these measured amounts. Then, the wind erosion amounts for segments five through forty are further calculated based on the wind erosion coefficient. Finally, the mass of sand transported by a sand collector is determined based on the set of wind erosion amounts corresponding to each of the forty segments. That is, the mass of sand transported by a sand collector is determined by the set of wind erosion amounts corresponding to each of the forty segments. The mass of sand transported by each sand collector , Indicates the first part, Indicates the first The wind erosion amount corresponding to each section is expressed in grams; the mass of sand transported by each sand collector is calculated in the same way, and will not be elaborated here.
[0052] In one specific embodiment, wind erosion = This embodiment does not limit this aspect.
[0053] Step 103: Determine the amount of wind-blown sand entering the gully for the slope to be determined based on the slope area, the mass of the transported sand, and the distance of the sand collector.
[0054] Specifically, after obtaining the mass of sand transported by each sand collector, the quantitative amount of wind-blown sand entering the gully for the slope to be determined is determined based on the slope area, the mass of sand transported, and the distance between the sand collectors.
[0055] In one specific implementation, the amount of wind-blown sand entering the gully of the slope to be determined is determined based on the slope area, the mass of sand transported, and the distance of the sand collectors. This includes: determining the mass of wind-blown sand flowing out of the gully slope of the slope to be determined based on the mass of sand transported by each sand collector and the distance of each sand collector; and determining the amount of wind-blown sand entering the gully based on the slope area and the mass of wind-blown sand flowing out of the gully slope.
[0056] In this step, the mass of aeolian sand flowing out of the gully slope can be calculated using mathematical methods such as the length-weighted average method based on the mass of sand transported by each sand collector and the distance between each pair of sand collectors. Due to the influence of the main gully topography, the direction of valley winds and mountain winds often differs significantly between night and day, and the wind direction of the main gully slope often does not align with the prevailing northwest wind direction. Therefore, it is difficult to segment the gully slope using the prevailing wind direction method. Considering the significant vertical difference between the gully edge and the main gully, the aeolian sand on the gully slope is significantly affected by gravity. Therefore, the sand cover on the gully slope exhibits a downward-sloping transport characteristic under the combined effects of gravity and wind. Therefore, the amount of aeolian sand entering the gully slope can be calculated based on the mass of sand transported by the sand collectors in the main gully. This embodiment does not limit this calculation.
[0057] Specifically, the mass of wind-blown sand on the outflowing gully slope of the slope to be determined is determined based on the mass of sand transported by each sand collector and the distance between each sand collector; the quantitative amount of wind-blown sand entering the gully is determined based on the slope area and the mass of wind-blown sand on the outflowing gully slope.
[0058] In one specific embodiment, the mass of wind-blown sand flowing out of the gully slope ,in, Indicates the first on the main channel The mass of sand transported by each sand collector. This indicates a unit conversion factor parameter. and The constant coefficient, for twice as much, Indicates the first on the main channel The distance between the sand collector and the measurement endpoint. Indicates the first on the main channel The sand-collecting instrument to the first The distance between sand collectors This indicates the distance between the measurement starting point on the main channel and the first sand collector.
[0059] In this step, , , The unit is meters, but this embodiment does not limit this.
[0060] in, For example, it could be 100. For example, it could be 2. For example, it could be 4, but this embodiment does not limit it.
[0061] Specifically, the mass of aeolian sand flowing out of the gully slope is calculated using the following formula: Mass of aeolian sand flowing out of the gully slope ,in, Indicates the first on the main channel The mass of sand transported by each sand collector. , and The constant coefficient, for twice as much, Indicates the first on the main channel The distance between the sand collector and the measurement endpoint. Indicates the first on the main channel The sand-collecting instrument to the first The distance between sand collectors This indicates the distance between the measurement starting point on the main channel and the first sand collector.
[0062] For example, Figure 2 This is one of the schematic diagrams of the main channel provided by the present invention, such as... Figure 2 As shown, the main channel includes , , , … and , Indicates the first A sand-collecting device, Indicates the first A sand-collecting device, Indicates the first A sand-collecting device, Indicates the first A sand-collecting device, Indicates the first A sand-collecting device, Indicates the first A sand-collecting device, Indicates the first on the main channel The sand-collecting instrument to the first The distance between sand collectors Indicates the first on the main channel The sand-collecting instrument to the first The distance between sand collectors is not limited in this embodiment.
[0063] For example, Figure 3 This is a second schematic diagram of the main channel provided by the present invention, as shown below. Figure 3 As shown, the main channel includes , , , … and , Indicates the first A sand-collecting device, Indicates the first A sand-collecting device, Indicates the first A sand-collecting device, Indicates the first A sand-collecting device, Indicates the first A sand-collecting device, Indicates the first A sand-collecting device, This indicates the fourth sand collector to the fifth sand collector on the main channel. The distance between sand collectors Indicates the first on the main channel The sand-collecting instrument to the first The distance between sand collectors is not limited in this embodiment.
[0064] In one specific implementation method, the amount of windblown sand entering the gully is quantified. ,in, Indicates the mass of wind-blown sand flowing out of the gully slope. This indicates the area of the slope.
[0065] Specifically, after obtaining the mass of wind-blown sand on the outflowing gully slope and the slope area, the quantitative amount of wind-blown sand entering the gully on the slope to be determined is determined based on the quotient of the mass of wind-blown sand on the outflowing gully slope and the slope area, i.e., the quantitative amount of wind-blown sand entering the gully. ,in, Indicates the mass of wind-blown sand flowing out of the gully slope. This indicates the area of the slope.
[0066] The advantage of this setup is that it enables accurate calculation of the amount of wind-blown sand entering the gully on a given slope, improves the accuracy of wind erosion observation, and is of great significance for guiding slope wind erosion protection.
[0067] For example, consider the wind erosion of the slope in a small watershed of a certain bay in the Wuding River basin, a sandy and coarse sandy area in the middle reaches of a certain river.
[0068] Table 1 shows the quantitative determination of wind-blown sand entering the gully. The measurement area belongs to the warm temperate semi-arid continental monsoon climate zone, with strong and frequent winds in winter and spring. The monthly average wind speed is between 2.13 and 3.17 meters per second, the annual average wind speed is 2.59 meters per second, and the average number of windy days per year is 20-40 days, mostly concentrated in spring. The gully section runs northeast-southwest, with a slope area of 14058.17 square meters and a main gully length of 319.33 meters. The distance L between adjacent sand collectors in the main gully is 75 meters. The experiment was conducted in the spring of a certain year, and two wind erosion events were observed. The quantitative wind-blown sand entering the gully is shown in Table 1. The quantitative wind-blown sand entering the gully in the measurement area is between 0.04 and 0.05 tons per hectare.

The method involves obtaining the slope area of the slope to be determined; where the slope area refers to the area of the slope surface from the gully edge line to the main gully channel of the slope to be determined, the gully edge line is the top boundary line of the slope to be determined, and the main gully channel is the channel of the slope to be determined; obtaining the mass of sand transported by all sand collectors on the main gully channel of the slope to be determined, and determining the distance between the sand collectors on the main gully channel; where the mass of sand transported is collected by sand collectors, the measurement area of the main gully channel of the slope to be determined includes a measurement start point, a measurement end point, and at least two sand collectors, and the distance between the sand collectors refers to the distance between any two of the measurement start point, measurement end point, and at least two sand collectors; and determining the quantitative wind-blown sand inflow into the gully channel of the slope to be determined based on the slope area, the mass of sand transported, and the distance between the sand collectors.
