Description

Technical Field

[0001] The present invention belongs to the technical field of soil and water conservation and agricultural production planning. Specifically, it is a method for determining the prohibited reclamation slope of regional soil and water conservation, and is particularly applicable to areas with steep terrain and scarce cultivated land resources such as alpine valley areas. Background Art

[0002] In areas with complex and steep terrain such as alpine valley areas, cultivated land resources are extremely scarce. On the one hand, over-reclamation has led to serious soil and water loss and caused great damage to the ecological environment. On the other hand, the demand for food security has prompted people to continuously develop and utilize limited cultivated land resources.

[0003] The traditional determination of the prohibited reclamation slope for soil and water conservation often adopts a unified standard and does not fully consider the differences in crop yields and soil and water loss degrees in different regions. This way of determining the prohibited reclamation slope restricts the exertion of agricultural production potential in some regions with high crop yields and relatively light soil and water loss; while in regions with low crop yields and serious soil and water loss, it is not sufficient to effectively protect the ecological environment.

[0004] Therefore, there is an urgent need for a method that can balance soil and water conservation and food security and determine the prohibited reclamation slope according to the actual situation of the region. Summary of the Invention

[0022] The terms "first", "second", etc. in the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same category, and do not limit the number of objects.

[0023] Figure 1 is one of the schematic flowcharts of a method for determining the prohibited reclamation slope of regional soil and water conservation provided by the present invention, as Figure 1As shown, the method includes step 110, step 120 and step 130. It should be noted that the execution subject of a method for determining the prohibited reclamation slope of regional soil and water conservation provided in the embodiments of the present application may be a device for determining the prohibited reclamation slope of regional soil and water conservation, or other computer devices, such as mobile phones, tablet computers, laptop computers, palmtop computers, in-vehicle electronic devices, wearable devices, Ultra-mobile Personal Computers (UMPCs), netbooks or Personal Digital Assistants (PDAs), etc. In this application, an example is given where the execution subject is a device for determining the prohibited reclamation slope of regional soil and water conservation, but it is not limited that the execution subject of the method for determining the prohibited reclamation slope of this application can only be a device for determining the prohibited reclamation slope of regional soil and water conservation.

[0024] Step 110, determine the slopes of all plots within the area to be evaluated.

[0025] Here, geographic information system (GIS), remote sensing technology or on-site measurement tools (such as clinometers) can be used to obtain the topographic data (such as topographic maps or digital elevation models DEM) of the area to be evaluated. Through the slope calculation algorithm, calculate the slopes of all plots within the area to be evaluated plot by plot, and each plot corresponds to a unique slope.

[0026] Step 120, divide the slopes of the plots into at least two slope intervals according to a preset slope interval.

[0027] Here, the preset slope interval can be set according to the research purpose or regional characteristics. For example, taking 1 degree as an interval, divide the slopes into multiple slope intervals.

[0028] In this embodiment, classify the slopes of each plot obtained in step 110 according to the set preset slope interval, and classify the plots into the corresponding slope intervals.

[0029] Step 130, determine the prohibited reclamation slope for soil and water conservation of the area to be evaluated based on the average soil erosion amount and the average cultivated land output amount within each of the slope intervals of the area to be evaluated.

[0030] Here, a soil erosion model (such as the RULSE model) can be used, combined with data such as rainfall, soil type, and vegetation cover, to estimate the annual average soil loss of the plots in each slope interval as the average soil erosion amount of each slope interval.

[0031] Furthermore, in this embodiment, the cultivated land crop yield data of the plots within each slope interval is also collected, and its annual average value is calculated as the average cultivated land output amount within each slope interval.

[0032] In one example, the average soil erosion amount and the average cultivated land output are determined as follows: Based on the soil erosion model, determine the average soil erosion amount within each slope interval of the area to be evaluated; Based on the land use data, agricultural product yield data, and farmer survey data, determine the average cultivated land output within each slope interval of the area to be evaluated.

[0033] Land use data refers to the types (such as paddy fields, dry land, etc.) and distribution of cultivated land in different regions. Agricultural product yield data is the statistical information on agricultural product yields collected and sorted by the agricultural department, statistical department, etc., including the total output data of various crops. Farmer survey data refers to the detailed data at the farmer level obtained through on-site visits to farmers, questionnaires, or interviews, such as the cultivated land area, types of crops planted, and yields of each household. In this embodiment, by leveraging the land use data in the national land survey, combining existing statistical materials, and using farmer surveys as a supplementary means, the average output of sloped cultivated land for plots within each slope range in the area to be evaluated is statistically obtained.

[0034] Finally, analyze the average soil erosion amount and the average cultivated land output in each slope interval to determine the soil and water conservation prohibited reclamation slope of the area to be evaluated. For example, when the average soil erosion amount in a certain slope interval is large and the average cultivated land output is low, the upper limit of this slope interval is determined as the soil and water conservation prohibited reclamation slope.

[0035] A method for determining the soil and water conservation prohibited reclamation slope of a region proposed in this embodiment determines the slopes of all plots in the area to be evaluated, divides them into at least two slope intervals according to a preset slope interval, and then determines the soil and water conservation prohibited reclamation slope of the area to be evaluated based on the average soil erosion amount and the average cultivated land output within each slope interval. The present invention comprehensively weighs the two core elements of crop yield and soil and water loss, changes the limitations of setting the prohibited reclamation slope with a unified standard in the past, makes the determination of the prohibited reclamation slope more in line with the actual situation of the region, effectively protects the ecological environment, and can meet the food production demand to the greatest extent.

[0036] It should be noted that each embodiment of this application can be freely combined, the order can be swapped, or it can be executed independently, and does not need to rely on or depend on a fixed execution order.

[0037] In some embodiments, based on the average soil erosion amount and the average cultivated land output within each slope interval of the area to be evaluated, determining the soil and water conservation prohibited reclamation slope of the area to be evaluated includes: Based on the average soil erosion amount within each slope interval of the area to be evaluated, determine the critical soil erosion slope of the area to be evaluated; When the critical slope of soil erosion in the area to be evaluated is not greater than 25 degrees, based on the average output of cultivated land in different slope intervals between the critical slope of soil erosion and 25 degrees in the area to be evaluated, determine the slope for soil and water conservation where cultivation is prohibited in the area to be evaluated.

[0038] Here, the critical slope of soil erosion refers to the slope that causes a sharp increase in soil and water loss.

[0039] In this embodiment, the average soil erosion amount in different slope intervals obtained by calculation can be compared and analyzed with the corresponding slope values to find the slope at which the soil erosion amount increases sharply. By analyzing the relationship between the average soil erosion amount and the slope, determine at which slope value the soil erosion amount begins to increase sharply, and this slope value is the critical slope of soil erosion.

[0040] In some embodiments, determining the critical slope of soil erosion in the area to be evaluated based on the average soil erosion amount in each slope interval of the area to be evaluated includes: Based on the average soil erosion amount in each slope interval of the area to be evaluated, construct a function between the slope and soil erosion in the area to be evaluated; Determine the slope corresponding to the inflection point of curvature in the function between the slope and soil erosion in the area to be evaluated as the critical slope of the area to be evaluated.

[0041] In this embodiment, first, the average soil erosion amount data in different slope ranges in the area to be evaluated are used to fit a function through a mathematical model. Then, the function is analyzed to determine the maximum inflection point of curvature of this function. It should be understood that the inflection point of curvature is the point on the function graph where the concavity and convexity change, that is, the turning point where the function graph changes from convex upward to concave downward or from concave downward to convex upward. The greater the curvature, the higher the degree of curvature of the curve at this point. Therefore, the maximum inflection point of curvature is the point with the largest curvature among all inflection points. Since near this point, the rate of change of the soil erosion amount with the slope changes significantly, the slope corresponding to this maximum inflection point of curvature is determined as the critical slope of soil erosion in this embodiment.

[0042] In this embodiment, when the critical slope of soil erosion in the area to be evaluated is not greater than 25 degrees, further combine the average output of cultivated land to determine the slope for soil and water conservation where cultivation is prohibited in the area to be evaluated in different slope intervals between the critical slope and 25 degrees.

[0043] In an example, determining the slope for soil and water conservation where cultivation is prohibited in the area to be evaluated based on the average output of cultivated land in different slope intervals between the critical slope of soil erosion and 25 degrees in the area to be evaluated includes: Starting from the critical slope of soil erosion in the area to be evaluated, determine the first slope at a preset slope interval. Determine the average output of cultivated land in the first slope interval within the range from the critical slope of soil erosion to the first slope in the area to be evaluated. In the case where the average output of cultivated land in the first slope interval is less than the average output of cultivated land in the alpine gorge area, determine the first critical slope of soil erosion as the slope prohibited from reclamation for soil and water conservation in the area to be evaluated.

[0044] Here, when the critical slope of soil erosion in the area to be evaluated is not greater than 25 degrees, the previously determined critical slope of soil erosion is used as the starting point for evaluation. Set a fixed slope interval, for example, 1 degree per interval. Starting from the critical slope of soil erosion, determine the next slope point, that is, the first slope. For example, if the critical slope of soil erosion is 15 degrees and the preset slope interval is 1 degree, then the first slope is 16 degrees.

[0045] Then, collect the average output of cultivated land in the range from the critical slope of soil erosion to the first slope as the average output of cultivated land in the first slope interval.

[0046] Here, the average output of cultivated land in the alpine gorge area is a reference value. For example, using the statistical yearbook as the data source, comprehensively collect the average output data of cultivated land in the alpine gorge areas across the country and use it as the reference benchmark for subsequent comparative analysis.

[0047] Finally, compare the calculated average output of cultivated land in the first slope interval within the range from the critical slope of soil erosion to the first slope with the average output of cultivated land in the alpine gorge area. If the average output of cultivated land in the first slope interval is lower than the average output of cultivated land in the alpine gorge area, then determine the critical slope of soil erosion as the slope prohibited from reclamation for soil and water conservation, that is, prohibit the reclamation of cultivated land with a slope greater than or equal to the critical slope of soil erosion.

[0048] In another example, it further includes: In the case where the average output of cultivated land in the first slope interval is not less than the average output of cultivated land in the alpine gorge area, determine the second slope at the preset slope interval corresponding to the first slope; the second slope is not greater than 25 degrees; Determine the average output of cultivated land in the second slope interval within the range from the first slope to the second slope in the area to be evaluated. In the case where the average output of cultivated land in the second slope interval is not less than the average output of cultivated land in the alpine gorge area, use the second slope as the first slope and continue to execute the determination of the second slope at the preset slope interval corresponding to the first slope until the average output of cultivated land in the second slope interval is less than the average output of cultivated land in the alpine gorge area, and determine the first slope as the slope prohibited from reclamation for soil and water conservation in the area to be evaluated.

[0049] When the average output of cultivated land in the first slope interval is not less than that of cultivated land in the alpine canyon area, it indicates that the output benefit of cultivated land in this slope interval is relatively good. At this time, it is necessary to further explore the output situation in higher slope intervals to determine whether the soil and water conservation prohibited reclamation slope can be appropriately increased, so as to make more reasonable use of land resources.

[0050] Specifically, on the basis of the first slope, continue to increase the slope according to the preset slope interval to obtain the second slope. For example, if the first slope is 16 degrees and the preset slope interval is 1 degree, then the second slope is 17 degrees, but it is necessary to ensure that the second slope does not exceed 25 degrees to meet the overall requirements of land management and agricultural production.

[0051] Continue to collect the average output of slope cultivated land in the interval from the first slope to the second slope as the average output of cultivated land in the second slope interval.

[0052] Compare the average output of cultivated land in the second slope interval with that of cultivated land in the alpine canyon area. If the average output of cultivated land in the second slope interval is not less than that of cultivated land in the alpine canyon area, it indicates that the output benefit of cultivated land in this slope interval is still relatively good. The second slope can be used as the new first slope, and continue to increase the preset slope interval on the basis of the first slope to determine the next second slope, and repeat the above process to further analyze the average output of cultivated land in higher slope intervals until the average output of cultivated land in the second slope interval in the interval from the first slope to the second slope obtained by a certain calculation is less than that of cultivated land in the alpine canyon area. At this time, the first slope is determined as the soil and water conservation prohibited reclamation slope, that is, it is prohibited to reclaim cultivated land with a slope greater than or equal to this first slope.

[0053] Furthermore, the method further includes: In the case where the critical soil erosion slope of the area to be evaluated is greater than 25 degrees, determine 25 degrees as the soil and water conservation prohibited reclamation slope of the area to be evaluated.

[0054] In this embodiment, when the critical soil erosion slope of the area to be evaluated is greater than 25 degrees, directly select 25 degrees as the prohibited reclamation slope.

[0055] The method for determining the regional soil and water conservation prohibited reclamation slope proposed in this embodiment comprehensively weighs the two core elements of crop yield and soil and water loss, changes the limitation of setting the prohibited reclamation slope by a unified standard in the past, avoids determining the prohibited reclamation slope from a single ecological or production perspective, and realizes the balanced development of soil and water conservation and food security.

[0056] For the sake of easy understanding, refer to Figure 2 , Figure 2 is the second flow chart of the method for determining the regional soil and water conservation prohibited reclamation slope provided by the present invention. AsFigure 2 As shown in the figure, it includes the following steps: Step 210: Obtain the average output of cultivated land in alpine canyon areas P 0 ; Here, the statistical yearbook can be used as the data source to comprehensively collect the average output of cultivated land in alpine canyon areas across the country P 0 , which is used as the reference benchmark for subsequent comparative analysis; Step 220: Calculate and classify the slopes of the plots in the area to be evaluated, and divide the slopes of the plots into multiple slope intervals at intervals of 1 degree; Step 230: Statistically calculate the average output of cultivated land in different slope intervals in the area to be evaluated P x ; Here, the land use data in the national land survey can be used, combined with existing statistical materials, and supplemented by farmer surveys to statistically calculate the average output of cultivated land in different slope intervals P x ; Step 240: For the area to be evaluated, calculate the average soil erosion amount Ex of each slope interval at intervals of 1 degree, establish the relationship between slope and soil erosion, and determine the critical slope of soil erosion ; Step 250: Judge whether the critical slope of soil erosion is greater than 25 degrees. If it is greater, execute Step 260; otherwise, execute Step 270; Step 260: Select 25 degrees as the prohibited reclamation slope for soil and water conservation; Step 270: In the interval from the critical slope of soil erosion to 25 degrees, starting from the critical slope of soil erosion , increase the slope at intervals of 1 degree; Step 280: Judge whether the average output of cultivated land in this slope interval P x is less than the average output of cultivated land in alpine canyon areas P 0 . If so, execute Step 290; otherwise, execute Step 290; Step 290: Select the upper limit of this slope interval as the prohibited reclamation slope for soil and water conservation; Step 300: Continue to increase the slope at intervals of 1 degree and return to execute Step 280.
