Technical Field

[0001] This invention relates to the field of land use and agricultural planting management technology, and in particular to a method, apparatus and electronic device for determining the priority of arable land use. Background Technology

[0002] In recent years, many farmers have chosen to plant non-grain crops with higher economic benefits due to profit-seeking, resulting in insufficient grain planting area. Although pilot areas have been selected to carry out research on the priority of farmland use, the priority of farmland use is usually determined by surveys of farmers' wishes and subjective experience. As a result, the priority of farmland use is not very comprehensive and is difficult to match the actual farmland conditions in different regions. Summary of the Invention

Attached Figure Description

[0039] Figure 1 This is a flowchart illustrating the method for determining the priority of cultivated land use in an embodiment of the present invention.

[0040] Figure 2 This is a schematic diagram of the structure of the farmland utilization priority determination device in an embodiment of the present invention. Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figure 1 The first aspect of this invention provides a method for determining the priority of arable land use, comprising the following steps S1 to S3:

[0043] Step S1: Obtain several cultivated land patches in the target area and divide the several cultivated land patches into several cultivated land use management units;

[0044] Step S2: Based on the preset farmland management requirements, crop type system, farmland attributes, historical planting data, and planting industry development information of the target area, determine the crop planting priority sequence corresponding to each farmland use management unit;

[0045] Step S3: Determine the farmland use priority order of the target area according to the crop planting priority sequence.

[0046] Specifically, to facilitate the management of farmland use priorities, this embodiment first acquires several farmland patches in the target area to identify the farmland areas within that target area. For example, farmland patches in the target area can be acquired based on the current farmland patches from the latest data of the Third National Land Change Survey. These farmland patches are then divided into several farmland use management units. It is worth noting that this embodiment does not specifically limit the number of farmland patches. For example, for county-level areas, the number of patches typically reaches tens of thousands or even more. Therefore, the number of farmland patches in this embodiment is determined by the actual size of the farmland area in the target area.

[0047] Furthermore, since the farmland management requirements, crop type systems, farmland attributes, historical planting data, and planting development directions differ in different regions, in order to better match the actual farmland conditions of the current target area and take into account the planting preferences of farmland users, this embodiment considers the above-mentioned factors and determines the crop planting priority sequence for each farmland use management unit from multiple aspects. It can be understood that the crop planting priority sequence clearly defines the preferred crops for planting under different factors for the farmland use management unit.

[0048] The method for determining the priority of cultivated land use provided in this invention divides cultivated land plots in the target area into cultivated land use control units. When determining the crop planting priority sequence corresponding to each cultivated land use control unit, it takes into account cultivated land control requirements, crop type system, cultivated land attributes, historical planting data, and planting industry development information of the target area. This significantly improves the rationality of the priority of cultivated land use and ensures that it can match the actual cultivated land situation in the target area.

[0049] As a preferred embodiment, dividing the plurality of cultivated land parcels into a plurality of cultivated land use management units specifically includes:

[0050] Based on the distance between each cultivated land parcel and the land ownership of each cultivated land parcel, several cultivated land parcels with a distance less than a preset distance threshold and / or the same land ownership are divided into the same cultivated land use management unit to obtain several cultivated land use management units in the target area.

[0051] Specifically, this embodiment divides the farmland use control units according to the principles of contiguous layout and consistent ownership. To determine whether the layout is contiguous, a buffer range, such as 50m, can be set in advance. The farmland plots are buffered outward by 50m from the boundary of the farmland plots, and the farmland plots within the buffer range are regarded as contiguous farmland plots. To determine whether the ownership is consistent, farmland plots with the same land use right holder can be regarded as farmland plots with consistent ownership. In the case of land transfer, the operator is used as the basis for judgment.

[0052] As a preferred embodiment, the step of determining the crop planting priority sequence corresponding to each of the cultivated land use control units based on preset cultivated land control requirements, crop type system, cultivated land attributes, historical planting data, and planting industry development information of the target area specifically includes:

[0053] Based on the farmland management requirements and the crop type system, the farmland management scope and permitted crop types of the target area are determined, and the boundaries of the farmland use management units are adjusted according to the farmland management scope to obtain several revised farmland use management units.

[0054] Based on the farmland attributes corresponding to each of the revised farmland use control units, suitable crop types that conform to the farmland attributes are selected from the permitted crop types; wherein, the farmland attributes include the natural zone, slope, soil layer thickness, organic matter content, soil texture, soil pH value, crop maturity, secondary land category of farmland, biodiversity information, and heavy metal pollution information.

[0055] Based on the historical planting data corresponding to each of the revised cultivated land use control units, select the preferred crop types that conform to the historical planting data from the suitable crop types, and determine the planting priority sequence of the preferred crop types;

[0056] Based on the information on the development of the planting industry, select encouraged crop types that conform to the information on the development of the planting industry from the types of crops that are preferred to be planted.

[0057] Based on the planting industry development information and the planting priority sequence of the preferred crop types, determine the planting priority sequence of the encouraged crop types;

[0058] Based on the permitted crop types, suitable crop types, preferred crop types, planting priority sequences of preferred crop types, encouraged crop types, and planting priority sequences of crop types, several crop planting priority sequences are determined for each of the modified farmland use control units.

[0059] Specifically, based on relevant policy requirements, such as high-standard farmland being used entirely for grain production in principle; permanent basic farmland being high-quality arable land legally designated and primarily used for grain production, especially ensuring the planting area of ​​the three major grains: rice, wheat, and corn; and general arable land being mainly used for grain, cotton, oilseed, sugar, vegetables, and forage production, this allows for the determination of arable land management requirements and a crop type system. This includes the arable land management scope formed by the boundaries of high-standard farmland, the permanent basic farmland protection red line, and the amount of arable land. This arable land management scope allows for further optimization of the boundaries of arable land use management units, ensuring the accuracy of arable land use priorities. Furthermore, the crop type system clarifies the specific classifications of various crop types such as grain, cotton, oilseed, sugar, and vegetables, defining the types of crops permitted for planting.

[0060] Furthermore, this embodiment, based on farmland quality-related indicators, includes six levels: natural geographical pattern, topographical conditions, soil conditions, crop maturity, current utilization, and ecological environment conditions. It specifies concrete property indicators, including the natural region, slope, soil thickness, organic matter content, soil texture, soil pH, crop maturity, secondary land use category, biodiversity information, and heavy metal pollution information. Since each crop among the permitted crop types has corresponding suitable farmland attributes, the permitted crop types can be further refined, eliminating unsuitable crop types and obtaining suitable crop types that conform to the aforementioned farmland attributes.

[0061] Furthermore, based on basic research data and data from field patrols under the field chief system, it is possible to clarify the historical crop selection patterns of each revised farmland use control unit. Combining this with data on crop type, planting cycle, and other relevant information, historical planting data is generated. Understandably, based on this historical planting data, the planting preferences of farmers within the revised farmland use control units can be identified. For example, based on planting area and quantity, preferred and secondary crop types can be determined. This allows for the selection of crop types that align with historical planting data and the determination of their planting priority sequence. The preferred crop type has the highest planting priority, the secondary crop type has the second highest priority, and so on, ranking the planting priorities of each crop type.

[0062] Furthermore, since some regions have distinctive crop industries due to factors such as climate, soil quality, and culture, and thus use these as the direction for planting development, in order to better match the actual arable land conditions of the target region, this embodiment selects encouraged crop types that conform to the planting industry development information from the preferred crop types. Since the planting priority sequence of preferred crop types has been analyzed and confirmed in the above steps, the selected encouraged crop types can be initially sorted in terms of planting priority based on the planting priority sequence of preferred crop types, and adjusted based on the planting development direction, so that the final planting priority sequence of encouraged crop types conforms to the planting development direction.

[0063] It is understandable that, based on the preferred planting types selected under different factors as analyzed above, several crop planting priority sequences can be obtained. For example, based on the permitted crop types, the permitted crop priority sequence corresponding to the current arable land use control unit can be obtained; based on the preferred crop types and their planting priority sequences, the preferred crop priority sequence corresponding to the current arable land use control unit can be obtained, etc. This embodiment will not elaborate further here.

[0064] As a preferred embodiment, the step of selecting a preferred crop type that matches the historical planting data from the suitable crop types based on the historical planting data corresponding to each of the modified arable land use management units, and determining the planting priority sequence of the preferred crop type, specifically includes:

[0065] Based on the historical planting data corresponding to each of the revised farmland use control units, determine the historical crop types corresponding to each of the revised farmland use control units and the planting tendency ranking of each of the historical crop types;

[0066] Select the preferred crop type from the suitable crop types that matches the historical crop types;

[0067] Based on the planting preference sort, determine the planting priority sequence of the preferred crop types.

[0068] As a preferred embodiment, selecting encouraged crop types from the preferred crop types that align with the planting industry development information, based on the planting industry development information, specifically includes:

[0069] Based on the aforementioned planting industry development information, the target crops for the target region are determined;

[0070] Select the encouraged crop type from the preferred crop types that matches the target industry crop.

[0071] For example, assuming that the characteristic planting industry of the target area is a certain sweet potato, then the sweet potato is regarded as the target industry crop of the target area. Sweet potatoes belong to one of the food crops, including rice, wheat, corn, sweet potatoes, etc. Thus, the encouraged planting crop type that matches the target industry crop, i.e. food crops, is selected from the preferred planting crop types, so as to eliminate crop types that are seriously deviating from the direction of planting development.

[0072] As a preferred embodiment, determining the planting priority sequence of the encouraged crop types based on the planting industry development information and the planting priority sequence of the preferred crop types specifically includes:

[0073] Based on the planting priority of the encouraged crop type in the planting priority sequence of the preferred crop type, an initial planting priority sequence for the encouraged crop type is determined;

[0074] The initial planting priority sequence is adjusted with the target crop as the highest priority to determine the planting priority sequence for the encouraged crop type.

[0075] Specifically, since the planting priority sequence of the preferred crop types already clearly defines the planting priority of each crop within the preferred crop types, and the encouraged crop types are obtained by further screening from the preferred crop types based on the direction of planting development, the initial planting priority of each crop within the encouraged crop types can be determined based on the planting priority sequence of the preferred crop types, thus forming an initial planting priority sequence. Furthermore, to align with the planting development direction of the target region, this embodiment adjusts the initial planting priority sequence with the target industry crop as the highest priority.

[0076] As a preferred option, the farmland use priority sequence includes a first-level required planting priority sequence, a second-level encouraged planting priority sequence, a third-level suitable planting priority sequence, and a fourth-level permitted planting priority sequence.

[0077] Specifically, based on the crop planting priority sequences of each modified farmland use control unit obtained by considering different factors, this embodiment further divides the farmland use priority sequence of the target area into four levels: Level 1 Required Planting Priority Sequence, Level 2 Encouraged Planting Priority Sequence, Level 3 Suitable Planting Priority Sequence, and Level 4 Permitted Planting Priority Sequence. This allows for comprehensive planning from a regional, strategic, and overall perspective in determining the overall selection of crop types. It is worth noting that the Level 1 Required Planting Priority Sequence is formed based on the crop types that must be planted according to farmland control requirements; the Level 2 Encouraged Planting Priority Sequence is formed based on the encouraged crop types and their planting priority sequences obtained by the above analysis, i.e., crop types encouraged to be planted considering the unified development of local agricultural industries and brand building; the Level 3 Suitable Planting Priority Sequence is formed based on the suitable crop types obtained by the above analysis, i.e., crop types suitable for planting considering local conditions such as climate, soil, and water resources; and the Level 4 Permitted Planting Priority Sequence is formed based on the permitted crop types obtained by the above analysis, i.e., the crop types remaining after eliminating prohibited crop types, and this type is the broadest.

[0078] As a preferred embodiment, the method further includes:

[0079] Based on the revised farmland use control units and the farmland use priority order, a farmland use priority control map of the target area is generated using ArcGIS tools.

[0080] Based on the historical planting data, the planting cycle information of each crop in the crop planting priority sequence is determined, and the planting cycle information is added to the cultivated land use priority control map.

[0081] Specifically, this embodiment can use ArcGIS's model builder and Python language to perform secondary development on the farmland use priority tool, and build six functional tools including a current farmland plot information grid processing tool, a current farmland policy control attribute analysis tool, a farmland quality analysis tool, a crop planting history and tradition analysis tool, an agricultural industry development spatial layout analysis tool, and a planting use integrated analysis and evaluation tool, so as to determine the farmland use priority. The existing cultivated land parcel information gridding tool is used to divide cultivated land plots into several cultivated land use control units, which serve as the base map for planting use control, forming a basic information database in shapefile format. The cultivated land area of ​​the base map is further optimized using the existing cultivated land policy control attribute analysis tool, clarifying the specific classification categories and types of crops that can be selected for each revised cultivated land use control unit, forming a basic grid unit crop sequence layer. Based on the permitted crop types, the cultivated land quality analysis tool further refines and clarifies the crop types suitable for cultivated land quality characteristics, forming a basic grid unit suitable crop sequence layer. Finally, the historical crop tradition analysis tool is used to identify crops within the same revised cultivated land use control unit that simultaneously meet the cultivated land control requirements. Crops with attributes such as suitability for cultivated land quality and historical planting traditions are prioritized to form a basic grid unit crop preference sequence layer. Using an agricultural industry development spatial layout analysis tool, based on the aforementioned priority sequence, crop types that align with the direction of planting industry development are further selected to form a basic grid unit target crop sequence layer. Using a planting use integrated analysis and evaluation tool, based on each revised cultivated land use control unit and the determined cultivated land use priority sequence, a cultivated land use priority information database is formed, and a cultivated land use priority control map of the target area is generated. Each revised cultivated land use control unit in the map has corresponding crop planting priority sequence information and planting cycle information for each crop. Additionally, a negative list of crop types for each revised cultivated land use control unit can be added.
