[0024] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] like Figure 1 As shown, the ecological restoration method of an embodiment of the present invention includes: constructing a plurality of interception dams of preset heights in the gully and arranged at intervals along the longitudinal direction of the gully, and the upper end surface of one of two adjacent interception dams among the plurality of interception dams is flush with the contact surface of the other interception dam with the ground; when the interval distance between two adjacent interception dams is greater than the preset interval distance, adjusting the interval distance between one interception dam and the other interception dam to the preset interval distance; planting vegetation in the gully; and constructing a transversely arranged water storage dam at the bottom of the gully, and the dam body height of the water storage dam is greater than the dam body height of the interception dam.

[0026] Specifically, the longitudinal direction of the gully is consistent with the direction of water flow in the gully, that is, a plurality of intercepting dams arranged in sequence are built in the direction of water flow, and the intercepting dams are arranged along the transverse direction of the gully. The height of the dam body of the intercepting dam is less than the depth of the gully at the location where the intercepting dam is built. By constructing a plurality of intercepting dams arranged in intervals in the gully, the water flow velocity in the gully is reduced, thereby reducing the scouring force of the water flow on the gully, which facilitates the sediment settlement in the water flow.

[0027] Specifically, by setting the upper end surface of the interception dam located downstream of two adjacent interception dams to be flush with the contact surface of the interception dam located upstream with the ground, the interception dams are distributed as evenly as possible on the slope of the gully, thereby improving the interception dams' effect of slowing down the water flow. In other words, the greater the slope of the gully, the smaller the horizontal spacing of the interception dams, and the more interception dams there are. Conversely, the smaller the slope of the gully, the larger the horizontal spacing of the interception dams, and the fewer the interception dams there are.

[0028] In this embodiment, by limiting the interval distance between two adjacent interception dams, when the interval distance between two adjacent interception dams is greater than the preset interval distance, the interception dam is constructed based on the preset interval distance to ensure that the interval distance between adjacent interception dams is within the preset interval distance range, thereby avoiding excessive interval distance between interception dams in areas with relatively gentle gullies, thereby affecting the interception dam's effect of slowing down the water flow, thereby ensuring the interception dam's effect of slowing down the water flow.

[0029] Optionally, the spacing distance between two adjacent interception dams may be a horizontal spacing distance between two adjacent interception dams, or may be a straight-line distance between two adjacent interception dams. In this embodiment, the spacing distance between two adjacent interception dams in the horizontal direction is used.

[0030] For example, the preset height of the interception dam is set to 0.5m-3m. The preset interval distance is 20-40m, which can be 20m, 25m, 40m, and in this embodiment, the value is 40m.

[0031] For example, a water storage dam can be built with clay or mortar masonry, and the permeability of the dam is less than 1.0×10 -5 cm / s, artificial anti-seepage measures such as modified soil or anti-seepage membrane can also be taken to prevent water from infiltrating the dam body and affecting the stability of the dam body. On the other hand, it can reduce water loss and improve the water storage capacity of the dam.

[0032] For example, the height of the first interception dam is set to 2m, and the upper end face of the first interception dam is flush with the top of the gully. The position of the second interception dam is determined according to the dam body height of the first interception dam and the gully slope. If the horizontal interval between the determined position of the second interception dam and the first interception dam is greater than 40m, the second interception dam is built at a horizontal interval of 40m from the first interception dam, and the upper end face of the second interception dam is adjusted to be flush with the contact surface between the first interception dam and the ground. Then, the third interception dam is built according to the dam body height of the second interception dam and the gully slope. If the horizontal interval between the determined position of the third interception dam and the position of the second interception dam is within 40m, the third interception dam is constructed according to the actually determined position of the third interception dam, and so on, until the last interception dam is constructed.

[0033] The ecological restoration method of the embodiment of the present invention constructs a plurality of interception dams in the gully at intervals along the longitudinal direction of the gully, determines the construction position of the interception dam according to the dam body height of the interception dam and the interval distance between two adjacent interception dams, and limits the interval distance between adjacent interception dams in the vertical direction and the interval distance between adjacent interception dams in the horizontal direction, so that the adjacent interception dams are arranged evenly on the gully slope as a whole, which makes it easier for the interception dams to intercept water flow, reduce the flow rate of water flow, and thus reduce the scouring of the gully by water flow, facilitate the uniform sedimentation of sediment in the water flow, and reduce soil erosion and improve the stability of the ecological environment by planting vegetation in the gully.

[0034] Furthermore, by building a dam at the bottom of the gully, it is convenient to collect the water flow in the gully, and by reusing the water in the dam, the temporal and spatial distribution of water can be adjusted.

[0035] In some embodiments, a water storage dam is constructed at the bottom of a gully, including: determining a water storage volume according to rainfall, a catchment area, and a runoff coefficient, where the water storage volume can be expressed as: V=10APα, where V represents the water storage volume, A represents the catchment area of ​​the gully, P represents the average annual rainfall, and α represents the runoff coefficient; determining a dam body height of the water storage dam according to the water storage volume, the width of the gully, and the longitudinal slope of the gully, where the dam body height of the water storage dam can be expressed as: Among them, H represents the height of the dam, i represents the average slope of the gully, and L represents the average width of the gully.

[0036] Specifically, the unit of impounded water volume is m 3 The unit of annual average rainfall is mm. The rainfall is based on the annual average rainfall of previous years. For example, the annual average rainfall of the previous year can be taken, or the annual average rainfall of the previous three years can be taken. The annual average rainfall can be obtained directly from the Meteorological Bureau. The unit of gully confluence area is hm 2 The catchment area refers to the horizontal projection area of ​​the catchment surface. The boundary line of the catchment area is formed by a series of ridge lines (watersheds) and roads and dams. The catchment boundary can be circled on the topographic map to measure the catchment area. The runoff coefficient is the ratio of runoff to rainfall. The runoff coefficient can be directly obtained from the water conservancy department.

[0037] In the embodiment of the present invention, the retained water volume is determined by rainfall, catchment area and runoff coefficient, and the height of the dam body is determined based on the retained water volume combined with the width and slope of the gully, so as to facilitate the water storage dam to collect the water flow in the gully, avoid the dam body of the water storage dam being too low, and the water flow in the gully overflowing the dam body of the water storage dam, and at the same time avoid the dam body of the water storage dam being too high, which increases the construction cost. This embodiment improves the water storage performance of the water storage dam by determining the dam body height of the water storage dam within a certain range according to actual conditions.

[0038] In some embodiments, planting vegetation in a gully includes: planting first plants at the bottom of the gully, wherein the first plants are shrubs and herbs, and the spacing between shrubs is 0.5m-2m; planting first plants and / or second plants on the slope of the gully, wherein the second plants are herbs.

[0039] Specifically, since the bottom surface of the gully is relatively flat, it is convenient to plant shrubs and herbs at the bottom of the gully. Planting shrubs or herbs on the gully slopes, and planting herbs on the gully slopes that are not suitable for planting shrubs and herbs, by planting vegetation in the gully, soil and water loss can be reduced.

[0040] It is understandable that the shrubs can be shrubs of one variety, or a mixture of shrubs of multiple varieties, or shrubs of multiple varieties can be planted independently in different areas. When planting shrubs and herbs, the herbs are planted first and then the shrubs. For example, shrubs such as sea buckthorn and / or caragana can be planted in different areas or alternately.

[0041] In some embodiments, planting the first plant and / or the second plant on the slope of a gully includes: planting the first plant on the slope of the gully when the angle of the slope of the gully is less than or equal to a preset angle; and planting the second plant on the slope of the gully when the angle of the slope of the gully is greater than a preset angle.

[0042] In this embodiment, the plants planted on the gully slope are determined by the gully slope angle of the gully, and different plants are planted according to the gully slope angles at different positions of the gully, thereby improving the survival rate of the plants and further improving the vegetation coverage rate.

[0043] For example, the preset angles are 10°, 15°, 20°, 25°, and 30°. The preset angle in this embodiment is 25°.

[0044] In some embodiments, after constructing a water storage dam at the bottom of the gully, the restoration method further comprises: transferring water in the water storage dam to the slope vegetation.

[0045] Specifically, a water storage dam is built in a flat area downstream of the gully. The water storage dam collects the water flow in the gully and transports the collected water to the slope vegetation planted on the slope. The slope vegetation is irrigated with water from the water storage dam to increase the slope vegetation coverage rate and further reduce slope soil erosion.

[0046] In some embodiments, conveying water in a water storage dam to slope vegetation includes: conveying water in the water storage dam to a slope water storage component; and irrigating the slope vegetation with water in the slope water storage component through an irrigation component.

[0047] Specifically, a water storage dam is built in a flat area downstream of the gully. When irrigating the slope vegetation, a slope water storage component is built at a high position on the slope. Since the water storage dam is located at the bottom of the gully, and the slope water storage components are located at a higher position in the slope vegetation irrigation area on both sides of the gully, a water transfer component is built between the water storage dam and the slope water storage component, so that the water in the water storage dam can be transported to the slope water storage component, and then the slope vegetation can be irrigated through the slope water storage component.

[0048] For example, the water storage capacity of the slope water storage component can be determined comprehensively based on site conditions, irrigation area, and irrigation cycle.

[0049] For example, the irrigation component is used to transport water from the slope water storage component to the lower slope areas on both sides for irrigation and maintenance of vegetation in the slope area. The irrigation component is set in the slope vegetation irrigation area and irrigates by gravity, including main pipes, branch pipes, valves, sprinklers, etc. The main trunk in the irrigation component is generally arranged along the main slope direction of the slope, and the branch pipes are arranged along the contour line, which is conducive to controlling the head loss of the branch pipe, making the working pressure of each nozzle on the branch pipe as uniform as possible, and improving the uniformity of irrigation.

[0050] It is understandable that the water in the storage dam can also irrigate the vegetation in the gully, increase the vegetation coverage in the gully, intercept sediment through vegetation, and reduce soil erosion in the gully.

[0051] In some embodiments, an upper end surface of an interception dam adjacent to the top of the gully among the plurality of interception dams is flush with the top of the gully, and a spacing distance between the interception dam and the top of the gully is within a preset spacing distance.

[0052] Specifically, the construction location of the first interception dam can be determined according to the actual environment in the gully. For example, the height of the dam body is different when it is built 20 meters away from the top of the gully and when it is built 25 meters away from the top of the gully, which facilitates the selection of a suitable location to build the interception dam and reduces the difficulty of construction.

[0053] It is understandable that due to the different geographical environments at different locations in the gully, there is a construction location determined based on the contact surface between the dam top of the downstream interception dam and the upstream interception dam and the ground between two adjacent interception dams or based on the horizontal spacing distance between two adjacent interception dams that is not suitable for building an interception dam. The construction error can be set to move the determined construction location upstream or downstream by a set error distance to reduce the difficulty of building the interception dam.

[0054] For example, the error distance is 5m.

[0055] In some embodiments, the spacing distance between two adjacent interception dams is the horizontal spacing distance between two adjacent interception dams.

[0056] Of course, in other embodiments, the interval distance between two adjacent interception dams may be used as the straight line connection distance between the two adjacent interception dams.

[0057] In some embodiments, the preset height is 0.5m-3m.

[0058] In this embodiment, the preset height of the interception dam is limited to prevent the dam body height from being too low, which will not reduce the water flow speed, and to prevent the dam body height from being too high, which will affect the downward flow of water. The actual height of the interception dam can be specifically limited according to the material of the interception dam, which is convenient for local materials, and then the actual height of the interception dam can be determined according to different materials. For example, when the interception dam is an earth dam, the dam body height of the interception dam is 0.5-3m, and when the interception dam is a wooden pile dam, the dam body height of the interception dam is 0.5-1.5m.

[0059] Of course, in other embodiments, the height of the intercepting dam may also be a value other than 0.5m-3m, the height of the intercepting dam may also be less than 0.5m, or the height of the intercepting dam may also be greater than 3m.

[0060] In some embodiments, the preset interval distance is 20m-40m. By limiting the preset interval distance, it is prevented that the interval distance between two adjacent interception dams is too large or too small, thereby ensuring the interception dam's effect of slowing down the water flow in the gully.

[0061] The ecological restoration system of this embodiment includes multiple interception dams 1 and water storage dams 3. The multiple interception dams 1 are arranged at intervals in the longitudinal direction of the gully 100. The upper end surface of one of two adjacent interception dams 1 among the multiple interception dams 1 is flush with the contact surface of the other interception dam 1 with the ground, and the interval distance between the two adjacent interception dams 1 meets the preset interval distance. The gully 100 is suitable for planting vegetation 2; the water storage dam 3 is arranged at the bottom of the gully 100, and the dam body height of the water storage dam 3 is greater than the dam body height of the interception dam 1.

[0062] like Figure 2 and Figure 3 As shown, the ecological restoration system of this embodiment also includes a water delivery component 500, a slope water storage component 200 and an irrigation component 300. The slope water storage component 200 is adjacent to the top of the slope. The water delivery component 500 is respectively connected to the water storage dam 3 and the slope water storage component 200 to transport the water in the water storage dam 3 to the slope water storage component 200. The irrigation component 300 is arranged on the slope and connected to the slope water storage component 200, so as to facilitate the water in the slope water storage component 200 to irrigate the slope vegetation 400 through the irrigation component 300, thereby improving the vegetation irrigation guarantee rate, increasing the survival rate and vegetation coverage of the slope vegetation 400, and thus improving the soil and water conservation capacity of the slope vegetation 400.

[0063] Optionally, the vegetation 2 planted in the gully includes shrubs 21 and herbs.

[0064] For example, the water delivery assembly 500 includes a water lift pump and a delivery pipeline.

[0065] The ecological restoration system of this embodiment establishes a plurality of interception dams 1 arranged at intervals along the longitudinal direction in the gully 100, so as to reduce the flow potential energy of the collected water through the interception dams 1, delay the flow rate of rainwater, slow down the scouring force of the water flow on the gully 100, increase the sediment settlement amount in the rainwater, and control soil loss. The settled sediment settlement is intercepted by the interception dam 1, and the erosion potential energy of rainwater is reduced by planting vegetation 2 in the gully 100, and the rainwater storage capacity is increased by the vegetation 2, thereby reducing rainwater runoff, and improving the vegetation 2 coverage rate of the gully 100, thereby further reducing soil and water loss.

[0066] Furthermore, by constructing a water storage dam 3 at the bottom of the gully 100, the water in the gully 100 is stored, the water loss is reduced, and it is convenient to irrigate the surrounding vegetation during drought, so as to adjust the temporal and spatial distribution of water resources. The water in the water storage dam 3 is used to irrigate the slope and the vegetation 2 in the gully 100, thereby improving the natural conditions in which the growth and development of vegetation are restricted by water, providing a guarantee for the growth and development of vegetation, improving the survival rate and coverage rate of vegetation, and improving the soil and water conservation capacity of vegetation in the Loess Plateau. The interception of water and soil resources is achieved by the interception dam 1 and the vegetation 2 in the gully 100, and the water storage is achieved by the water storage dam 3. The slope vegetation 400 is irrigated by the conveying component, the slope water storage component 200 and the irrigation component 300 to achieve water resource reuse, thereby improving the utilization rate of water resources and improving the stability of the ecological environment.
