Description

Technical Field

[0001] The present invention relates to the field of government service technology, and in particular to a method and system for registration of the second round of extension of rural land contracts. Background Art

[0002] The traditional method for registering second-round extensions of rural land contracts involves collecting household identity information, land parcel spatial information, contracting relationships, and land use status data during the second round of land contract extensions, targeting changes in household contracted land ownership, renewal confirmations, and changes in the contracting entity. County-level natural resources departments then organize and archive this data for integration into the real estate registration system. Traditional methods typically involve field surveys, manual mapping, paper form completion, household visits, and subsequent manual data entry to complete data collection and registration application preparation. Core aspects of this process include developing location coding rules, verifying contracted land parcel numbers and areas, reviewing family members' contracting rights, filling in agricultural land classification fields, and generating registration application codes. Registration materials rely on offline processes for step-by-step reporting and information entry.

[0003] In the existing technology, field classification is not independently identified in combination with content features, and there is a lack of rules to support the source of certificate number content, which leads to classification ambiguity between different certificate number types. Periodic information is not introduced to determine the difference in the direction of previous and subsequent records, resulting in a lack of logic for land phase division, an isolated use information structure, and classification attributes that cannot be mapped to the associated dimensions between registration fields. There is a lack of a linkage mechanism between the authority field content and use characteristics, making it difficult to ensure consistency in attribute expression during data reading and registration updates. Path information is not embedded in the field structure, and registration record nodes are separated. In data flow and information aggregation scenarios, faults are prone to occur, affecting structural stability. Summary of the Invention

[0022] See also Figure 1 The embodiment of the present invention provides a method for registering the second round of extension of rural land, including the following steps: S1: Obtain the land transaction certificate number field and contract management certificate number field from the second round of rural land contract extension registration data, extract the first character and character length information, map the extracted content to the transaction and contract type field positions in the field structure classification standard, write the ownership information into the field registration content, and obtain the certificate number field ownership information registration item; S2: Based on the content of the contracting type field in the registration item of the certificate number field, extract the current record and previous record of the corresponding land parcel extension period, read the direction of the current value and previous value fields, classify the period type according to the reading results, map the classification type to the land parcel code and unit number, and write them into the registration field to obtain the land parcel extension period type identifier; S3: Based on the parcel number of the newly added period in the parcel extension period segment type identifier, extract the use field, use classification field, and operation mode field, extract the content according to the field arrangement order, match the use standard classification, and write the use category corresponding to the parcel into the registration field structure to obtain the extended use adaptation combination information; S4: Based on the plot number in the extended use adaptation combination information, extract the transfer control, use period, and reallocation condition contents in the authority field, associate each authority field with the contents of the use field, use classification field, and operation mode field, and obtain the plot authority field adaptation result record by matching the field values ​​during the association process; S5: Based on the data number with the adaptation status in the adaptation result record of the land parcel authority field, extract the unit code field and extension period field information, append the path field content to the path table according to the direction logic mapped by the period segment, and then synchronously fill the corresponding values ​​of the purpose field and the authority field into the path node structure to obtain the extension path structure attachment record.

[0023] The registration items of the certificate number field ownership information include the first character information, character length information, field ownership classification, and field position identification; the land parcel extension period type identification includes the current value of the extension period, the previous value of the extension period, the field direction category, the period mapping type, the land parcel identification code, and the unit identification number; the extension use adaptation combination information includes the use field content, the use classification content, the operation method content, and the use standard classification result; the land parcel authority field adaptation result record includes the flow control parameters, the use period setting, the reallocation condition parameters, and the field value adaptation result; the extension path structure attachment record includes the path additional field, the path node structure content, the unit code corresponding value, and the extension period corresponding value.

[0024] The specific steps of S1 are: S101: Obtain the land transaction certificate number field and the contract management certificate number field in the second round of rural land contract extension registration data, extract the first character and length value of the field and correspond them to the field characteristics in the structure classification standard, match the starting character and length parameter position, and obtain the field structure matching result; First, locate and call the source data content. In actual applications, two table data files such as "Registration Form A.xlsx" and "Registration Form B.xlsx" can be called. During the operation, each data record in the "Land Transaction Certificate Number" column and the "Contract Operation Certificate Number" column is read respectively. For each record, its first character is extracted, that is, the first character of the string is called. For example, the first character of "J320109" is "J". Then, its length value is obtained, which can be directly determined by calling the string length attribute, which is 7 bits in this example; then, the obtained first character and length value are compared with the transaction and contract field feature content in the field structure classification standard. The standard is generally given in a table form. For example: the transaction field requires the first character to be "T" or "J" and the length to be 7 or 9, and the contract field requires the first character to be "C" or "P" and the length to be 8 or 10; each extracted content is matched, that is, it is judged Determine whether its first character is included in the allowed value list of the specified transaction class or contracting class, and at the same time determine whether its length value is within the specified range. Assuming that the first character of a record is "J" and the length is 7, it meets the two feature requirements of the transaction class field at the same time; if the first character of another record is "C" and the length is 8, it is matched to the contracting class field; in this process, the execution of the judgment action involves two parallel processing operations: first character list matching and length range judgment. After completing this type of feature comparison operation for all fields, the matching status is recorded in the result, that is, the label of whether the conditions are met is recorded as "transaction class" or "contracting class" respectively. During the processing process, if a record is encountered whose first character does not meet the requirements but the length meets the requirements, such as the first character is "Z" and the length is 7, the match fails and is not classified into any field class; finally, combined with the data record index, each matched judgment result is stored corresponding to its original data to obtain the field structure matching result.

[0025] S102: Based on the matching content in the field structure matching results, the field names of the contracting and transaction categories are filtered, the first character and length range are filtered, and each field is mapped to the registration area in the order shown in the classification standard to obtain the field classification and attribution processing results; First, read the matching status table recorded in the previous stage, which contains the first character and length value of each certificate number record and the field type label to which it is classified. In the result, filter all field names marked as "contracting type" or "transaction type". For example, the field "J2308177" is transaction type and "C90182710" is contracting type. During the screening process, determine whether the field type label of each record is the target category. If it is other types, skip and do not process it. Then extract the first character and length value of these filtered fields respectively. For example, the transaction type record "J2308177" extracts the first character "J" and the length is 8; the contracting type record "C90182710" extracts the first character "C" and the length is 9. Then, compare again according to the first character range and length range allowed by the transaction type and contracting type in the classification standard to determine whether it still meets the feature requirements set in the latest version of the current classification standard. If it is found that the length of a field exceeds the upper limit allowed, such as the maximum allowed length of the contracting type is 10 and the extracted character is If the segment is 12 digits, the data should be excluded from this round of processing. After judgment, only fields that meet both criteria are retained and sorted according to the field sequence number in the classification standard. For example, if the classification standard requires the order of contracting fields to be: C-class number first, P-class number last, the fields matched to the contracting category are classified by the first character "C" and "P" and then arranged according to the order of appearance in the original record. After classification, the fields can be matched one-to-one with the registration area field sequence by number or other unique identifier. The registration area can be the field area number marked in the land parcel management registration table, such as "Area Field 01" to "Area Field 20". If a field is the third occurrence of the contracting field, it corresponds to the third item in the area field sequence. During the operation, the filtered field content is directly written into the corresponding area field position, keeping the field value unchanged and recording its category label and sequence number information in the target area. This forms a field distribution state that matches the registration area one-to-one, and ultimately obtains the field classification and attribution processing result.

[0026] S103: Based on the attribution content in the field classification attribution processing result, the field name and attribution type are extracted, their contents are written into the corresponding position of the field registration structure table, and the attribution type is associated with the original registration field block to obtain the certificate number field attribution information registration item; First, the field classification and attribution processing results are expanded item by item according to the record number, and the field name information and corresponding attribution type content contained in each record are extracted. The field name is generally composed of the header or field identifier of the certificate number item, and the attribution type is the category identified as the field in the classification standard, such as contracting or transaction type, etc. Then, the extracted field name and its attribution type information are combined into a field attribution record, and the field name information in the field attribution record is located to the corresponding column label number in the field registration structure table. The column label number is usually a structure sequence number based on the data source table. If the field registration structure table uses a field alias instead of the original header form to record, it is necessary to additionally perform field alias mapping conversion on the field name, and insert the attribution type information value at the located registration position. After processing the field attribution records item by item, the registration structure table assignment operation is completed. For example, if the attribution type of the field "HTBH" is "transaction type", "transaction" can be written in the corresponding column label position of "HTBH" in the field registration structure table. Easy Classification". To complete subsequent operations, the original registration field block needs to be matched and linked. According to the updated attribution type information in the field registration structure table, the corresponding content of the same field name in the original registration data is found, and the attribution field position in the corresponding record is assigned the same attribution type to form a consistent mapping between the attribution type and the original field. The fields of the original registration field block may include multiple fields such as "Contract Number" and "Contractor Number". Each field needs to be matched against the field name in the field registration structure table. The successfully matched fields can be directly matched by the field name or by cross-matching the field alias. If it is found that multiple field names correspond to the same attribution type, the same type value can be recorded in the attribution type field. For example, if "Contract Number" and "Contract Number" are both determined to be transaction-type fields, they can be uniformly assigned "Transaction Type" in their original field blocks. After completing the field information registration and block corresponding classification through the above operations, the certificate number field attribution information registration item is obtained.

[0027] The specific steps of S2 are: S201: Based on the content of the contracting type field in the registration item of the certificate number field, the corresponding land parcel code and land parcel extension period field are extracted, the current registration value and the previous registration value are located in the data table, the time attribute of the field is collected, and the direction difference between the current value and the previous value in terms of time sequence is extracted to obtain the field time direction; First, extract the field names corresponding to all contract-type fields from the registration items, locate the actual position of each field name in the data record table, and identify the plot code field associated with it within the data interval where it is located. The plot code is used as a unique identifier to identify and confirm the ownership of records of different plots. After the identification is completed, the exact row number of each record in the data table is confirmed by the plot code, and then the original content of the extension period field is extracted in the same row. This field usually indicates the description information of the extension period or use period involved in the plot. Then, by comparing the plot code, find the corresponding historical registration record in the data table, identify the previous data version of the same plot as the current registration item, extract the extension period field content, and set the historical record in pairs with the current record. Determine its column number and row number position in the table in order to confirm the arrangement order of the time field. After completing the location positioning, the time limit descriptions in the two fields are identified, and the time start point elements and time end point elements involved are extracted from them. If the record form adopts a phased description, fuzzy time period expression or has other character modifications, it needs to be uniformly converted into a standard expression form, such as abstracting descriptions such as "after a certain year", "before a certain period", and "long-term" into corresponding logical serial numbers, and uniformly numbering and archiving them. Then, the starting point elements of the current record and the previous record are compared and judged. If the corresponding number of the starting point element of the current record is greater than the starting point number of the previous record, it is judged to be forward. If it is less, it is judged to be reverse. If the two are equal, the end point element number size is compared to confirm the time direction represented by the field. During the whole process, attention should be paid to handling time limit records with multiple expression formats, and the same number conversion method should be used for different expression types to keep the judgment standard consistent, and finally the field time direction is obtained.

[0028] S202: Based on the direction result in the time direction field, calculate the dominant direction value of the direction sequence in the current cycle, correspond records with a positive dominant direction to newly added cycles, and correspond records with a negative dominant direction to reduced cycles, to obtain a cycle type classification result; The calculation formula for the dominant direction value of the direction sequence in the current period is as follows: ; in, Represents the dominant direction value of the direction sequence in the current period, Represents the index number of the direction result record. Represents the total number of direction records in the current period, Representative The direction value of the bar direction result, Representative The time value recorded in the direction of the bar, Represents the arithmetic mean of direction recording time in the current cycle, Representative The frequency of occurrence of the row direction record in the current cycle, Represents the current cycle The sum of Represents all the The sum of represents the normalized stability control constant; In the current cycle, the total number of direction result records collected is , each record is shown below: Article 1: 、 minute, 、 ; Article 2: 、 minute, 、 ; Article 3: 、 minute, 、 ; Article 4: 、 minute, 、 ; Article 5: 、 minute, 、 ; Calculate the average time: ; Each item expands: Item 1: ; Item 2: ; Item 3: ; Item 4: ; Item 5: ; The sum of the numerators is ; Denominator calculation: ; ; ; ; ; ; ; ; ; Calculation of dominant direction value: ; Combining cycle judgment with technology: :New cycle, : Reduce cycle time; Result interpretation and numerical significance: The dominant direction value obtained in this calculation is , based on the weighted trend amplification processing and nonlinear normalization operation of all directional recorded data in the current period, the value represents the strength of the directional trend and the degree of directional aggregation within the period; Formula innovation description: The formula is beneficial in that by introducing a square root term based on the field time offset , combined with directional strength , direction frequency and local fluctuation correction , construct the product square trend term, and use The denominator normalization structure enhances the trend response stability, reduces the single-point interference amplitude, and performs nonlinear enhancement of directional trends and stable quantification of periodic state judgment.

[0029] S203: Based on the classification status in the period type attribution result, the period type information is written into the corresponding plot registration structure field position, and the period status is matched with the unit number and plot code fields, and the period field structure column is filled in to obtain the plot extension period segment type identifier; First, extract the cycle type information marked by the classification status field. The cycle type information is the key data content that describes the change of the cycle status in the extension registration. Common values ​​include "continuation type" and "restart type". After extracting the cycle type field, it is necessary to locate the plot code field associated with the cycle type in the plot information data table. The plot code is a unique identification field, which can be used to determine the target row position in the plot registration data set. At the same time, extract the column information of the registration structure field in the current row and confirm the field order. Identify the corresponding column number of the cycle type field in the current structure. For example, if the cycle field is in the sixth column of the structure table, fill the cycle type content into the corresponding cell position of the column, and further locate the unit number field corresponding to the plot. There is a one-to-one correspondence between the unit number and the plot code. Used to characterize the unit to which it belongs. In the plot registration structure, the unit number is usually arranged in a fixed field segment. Its relative position needs to be confirmed according to the field header information. The classification type value indicated by the period status is mapped to the period field column corresponding to the plot code and unit number row in sequence, and compared with other period field types in the same batch of plot data to confirm that its classification and attribution are consistent with the integrity of the registration structure. In actual operation, for example, for a plot numbered DK30561, if its period type is "continuation type" and the unit number is UC871, the period type value is filled in the period field position of the plot DK30561 corresponding to UC871. Finally, the corresponding filling between the classification status, unit code and plot code fields is completed to obtain the plot extension period segment type identifier.

[0030] The specific steps of S3 are: S301: Based on the parcel number of the newly added period in the parcel extension period segment type identifier, the use field, use classification field, and operation mode field are extracted, field codes and description information are collected in order of field arrangement, and the field order and registration structure position content are extracted to obtain the basic extraction result of the use field; First, locate the list of plot numbers involved in the newly added period, and by comparing the current period segment identification data with the historical period segment identification data, identify the plot number items that did not appear in the previous registration but appeared in the current data. After extracting each plot number in the result, read the corresponding row content in the plot information registration table in turn, and further extract the corresponding use field, use classification field and operation mode field from the row. The arrangement order of these three fields needs to be determined according to the field definition sequence of the registration table. After confirming the column number of each field in the field list, extract the field code and field description information in the corresponding column. The field code is the number field defined in the registration structure, such as the use code is YT001, the operation mode code is ZYF002, etc., and the field description information is the text content corresponding to the code. For types such as "orchard planting" and "manual tillage", after the extraction is completed, the field arrangement logic and the column order of the registration structure in the data table are further analyzed according to the registration table structure sequence. The position of each field in the header name sequence is determined by reading the header information, and the field content is verified to be consistent with the field value corresponding to the plot number. For example, for the plot numbered DK10472, its use field code is YT001, and the corresponding description is "grain planting", and the operation method field code is ZYF001, and the description is "mechanical sowing". At the same time, it is confirmed that the column order of these three fields in the table is the seventh, eighth and ninth columns respectively. Combined with the field sorting and field value, the order relationship between the fields is sorted to form a field arrangement detail based on the registration structure order, and finally the basic extraction result of the use field is obtained.

[0031] S302: Based on the field codes in the basic extraction results of the purpose field, the corresponding quantity between the field codes and the classification items in the standard classification path is calculated, the corresponding quantity is screened to achieve the field matching classification path, the classification path content is mapped to the corresponding field group, and the purpose field classification attribution result is obtained; The calculation formula for the corresponding amount of field codes and classification items in the standard classification path is as follows: ; in, Represents the corresponding amount of field code and classification item in the standard classification path, Representative Item field encoding, Representative Item standard classification value, Representative The standard deviation of the item field encoding, Representative The weight value of the item field, represents a constant term; The three field encoding items are: ; The standard classification values ​​are: ; Standard Deviation: ; Weight value: ; Constant term: ; Calculation process: for : ; for : ; for : ; Final result: ; Interpretation of results and numerical significance: The calculation result 9.846 represents the weight value of field attribution, which reflects the deviation and matching degree between the classification path and the field code, and is mapped to the corresponding field group to complete the attribution task of the purpose field classification; Formula innovation description: The formula's benefits lie in its ability to improve the adaptability of the classification path by introducing field encoding standard deviations and weights, combined with a constant term for normalization. The introduction of standard deviations reduces the impact of data fluctuations on classification results, and by setting weights, adjustments can be made based on the criticality of the fields, ensuring the compatibility of the classification path.

[0032] S303: Based on the classification content in the purpose field classification result, the land parcel number corresponding to the classification result is filled into the structure field position, and the purpose classification field and the operation mode field content are extracted and written into the registration column to obtain the extended purpose adaptation combination information; First, the classified field results are merged, and the plot number and the corresponding category in each record are extracted. For example, the record with plot number DK30317 corresponds to the category "planting". According to the number, its field position is located in the plot registration table, and the number is inserted into the corresponding field position in the registration structure table. The registration field can determine the position column number according to the field position mapped by the category. Then, the original registration value of the corresponding use classification field and operation mode field is extracted with the same number as the index. The field value is usually composed of a code and a description. For example, the use classification field is FL107, and the corresponding description is "vegetable planting". The operation mode field is ZY205, and the corresponding description is "drip irrigation farming". After obtaining the contents of these two fields, their codes and The description content is written into the preset column number position in the original registration structure table. The column number can be determined according to the field classification registration template structure. For example, the use classification field is in the tenth column and the operation method field is in the eleventh column. This operation needs to be performed one by one for multiple plot numbers to form a batch docking diagram of the number and field content. For example, if there is another record with the number DK30318, its category is "breeding", the corresponding use classification is FL206 "aquaculture", and the operation method is ZY312 "fenced breeding", then these three data are filled in the corresponding columns in sequence and kept one-to-one corresponding with the above records to ensure that each category result can be mapped to a specific field and accurately located in the structure field column position associated with the corresponding plot, and finally the extended use adaptation combination information is obtained.

[0033] The specific steps of S4 are: S401: Based on the plot number in the extension purpose adaptation combination information, the transfer control, use period, and reallocation condition contents in the authority field are extracted. The authority field contents are read in the order of the fields and classified into the corresponding plot number information to obtain the authority field classification result. First, determine the plot code corresponding to each record. For example, for the record with plot number DK40121, call the index position of the number in the extension use adaptation combination table, and extract the three permission information fields corresponding to the number according to the permission field setting order, namely the circulation control field, the use restriction field and the reallocation condition field, and read their corresponding values ​​in field order. In actual operation, the circulation control field may be "restricted circulation", the use restriction field may be "restricted use", and the reallocation condition field may be "natural update". The content of the permission field after reading should be combined with the arrangement order in the field setting table and classified into the same plot number record in the preset order. This order can be used to uniformly process the records under different plot numbers. The permission information format ensures that there is no overlapping or omission between fields. For example, when processing another record with a plot number of DK40133, if the permission fields are read as "allowed to circulate", "standard use" and "collective reallocation" in sequence, they will be classified into the permission information row under that number in order. If a null value or a field that does not match the format appears during the permission field reading process, it should be skipped or filled with a null value according to the field definition rules to avoid affecting subsequent classification operations due to format abnormalities. After completing the above information matching, a mapping relationship is established between the read permission field content and the plot number to which it belongs to form a one-to-one corresponding data index, which is included in the permission classification information for centralized and unified processing to finally obtain the permission field classification result.

[0034] S402: Based on the classification result of the authority field, the flow control field is mapped to the purpose field, the use period field is mapped to the purpose classification field, and the reallocation condition field is mapped to the operation mode field. The contents are read according to the field correspondence to obtain the field correspondence comparison content; First, locate the authority field content under each plot record. For example, for the record with plot number DK40207, obtain its transfer control field "restricted transfer", use period field and reallocation condition field "collective resolution" in the authority field classification table. Then call the use field table corresponding to the plot number to extract the use field "forestry and fruit planting", use classification field "economic forest type" and operation method field "manual weeding" under the number. In the field correspondence operation, the authority field should be matched with the use field content in a fixed order. Specifically, the transfer control field corresponds to the use field, the use period field corresponds to the use classification field, and the reallocation condition field corresponds to the operation method field. After the three sets of fields are connected, the field content is read. For example When "restricting transfer" is connected to "forestry and fruit planting", the field attribute matching table is called to read the functional type parameters of the two fields to determine whether their attribution is consistent or whether they belong to a collaborative application type. If the attribute of the read field pairing result is "non-mutually exclusive", the corresponding relationship is determined to be valid. In actual operation, it can also handle combined content such as "allowing transfer" and "food crops" or "collective resolution" and "mechanized farming and sowing". During the process, it is necessary to ensure that the field reading order is consistent with the field arrangement rules. If any field fails to read the corresponding value or the read value is empty, the current pairing record will be removed from the corresponding set and marked as pending. Finally, the corresponding reading operation of the authority field and the use field of all plot records is completed to obtain the field corresponding comparison content.

[0035] S403: Based on the field matching content, the matching status between the field values ​​is filled into the authority status field, and the matching status is located correspondingly with the land parcel information to obtain the land parcel authority field adaptation result record; First, traverse the plot numbers one by one for the comparison records that have been read, and use this as the index parameter to call the associated comparison result content. For example, for the record with plot number DK40308, its field comparison content is "the use field is consistent with the circulation control field", "the use classification field is inconsistent with the service life field", and "the operation mode field is consistent with the reallocation condition field". Make a unified judgment on the matching status of the three groups of fields, and regard the corresponding results of the same field value as "match", and the corresponding results of different field values ​​as "unmatched". Fill in each group of judgment results in the permission status field column according to the field order. If there is no matching relationship in the corresponding position of the field or the matching status is empty, fill in the "missing" mark in the corresponding permission status position. During the filling process, it is necessary to follow the order between the fields. The order is fixed as the circulation control field, the usage period field, and the reallocation condition field to avoid data positioning offset due to the disorder of the field order. Then the judgment result in the authority status field is matched one by one with the original plot information to ensure that the plot number and its corresponding authority matching result are uniquely mapped. During the operation, it is necessary to check whether the plot number field is repeated or the corresponding field content is incomplete. If there is a field break or number mismatch, the current record writing operation should be terminated and included in the record exception list. The "match", "mismatch" and "missing" contents in the comparison results are uniformly imported into the plot information summary table, and the authority field matching status value is added to each plot record. Finally, the status filling process after the full field comparison is completed to obtain the plot authority field adaptation result record.

[0036] The specific steps of S5 are: S501: Based on the data number with the adapted status in the land parcel authority field adaptation result record, extract the unit code field and the extension period field content, link the period segment direction with the unit code field for parcel direction analysis, and append the path field according to the number mapping order to obtain the additional content of the path direction; First, filter out all the plot numbers with the status field as "adaptive" in the adaptation record set, and request the corresponding unit code field and extension period field value from the associated data table based on the number field in each record, confirm whether the unit code field is fully filled in and there are no blank items, and then call the direction value recorded in the cycle segment field according to the linkage rule between the unit code field and the cycle segment direction. For example, if the cycle segment direction is "forward" or "backward", the corresponding unit codes are arranged in sequence according to the numbering rules. If the direction is forward, the unit code is appended in ascending order. If it is backward, the unit code is appended in descending order. Before performing the append operation, it is necessary to disassemble and judge according to the coding level in the unit code field. If the unit code is "UA1201", it should be confirmed that "UA" is the administrative prefix and "1201" is the unit number. Parse the unit number and match its position in the sequence chain according to the cycle segment direction. Then, according to The path field is filled with numbers in the order of number mapping. The path field sequence is maintained during the append operation to avoid blank numbering. If there is a number skip during the continuous numbering process, the missing position must be marked with a "null value" and the position identifier of the missing position must be supplemented at the end of the data. Batch splicing operations should not be used throughout the process. Instead, each data should be processed separately and the path field should be written back. For example, if the plot number is DK50102, the corresponding unit code is UA1302, and the cycle segment direction is backward, the path field should be filled in the order of "UA1303", "UA1302", and "UA1301". The number of path segments is determined by the year value in the extension period field. If the year value is 3 years, the path segment position is 3 digits. The path numbers are filled in sequentially from the last segment to the first segment position. Finally, the joint append process of the direction segment path and the number segment is completed in the record set table to obtain the path direction append content.

[0037] S502: Based on the path direction additional content, read the current field values ​​in the usage field and the authority field of the corresponding land parcel, locate the field values ​​in the node structure field according to the corresponding order of the field structure, and fill in the corresponding position to obtain the field mapping filling result; First, extract the plot number recorded in the additional content as the index parameter, and search the use field and authority field content associated with the plot number in the data table one by one. During the reading process, the use field, transfer control field, use period field and reallocation condition field must be captured in sequence according to the field order, and the extracted results are sorted into use field value sets and authority field value sets, and numbered in field order. For example, the record with plot number DK30507 has a use field of "planting land" and the authority field contents are "transferable, 5 years, and not reallocated" in sequence. Then, according to the field arrangement order defined by the field structure, the use field is positioned as the first field in the first position of the node structure field, and the authority field is written into the subsequent positions of the node structure field in sequence, that is, "transferable" as the second position, "5 years" in the third position, and "not reallocated" as the fourth position. Cross-sorting is not allowed during the process. Or the fields are misplaced. If a field is empty, write the "null value" mark at the node field position to ensure that the total length of the structure table field is consistent with the field structure definition. Then, combine and locate according to the segment number and plot number in the path field. For example, if the path segment is PD03 and the corresponding plot number is DK30507, the node structure field identifier should be PD03-DK30507. The structure field filling operation is limited to each data slot under the identifier field. After filling is completed, the result is marked as "filling completed" status. During each field writing process, the field type and the target slot type need to be judged for field type consistency. If there is a field value type of text but the target slot is in numeric format, the data transcoding rule should be called before writing to translate the field value format. For example, "5 years" should be converted to the integer value "5" before writing. Finally, the mapping and filling of all node field contents are completed to obtain the field mapping filling result.

[0038] S503: Based on the field mapping filling result, the path field content and the node field structure are aggregated, and the content is written according to the number information to obtain the extension path structure attachment record; First, extract the path field content and node field structure content corresponding to each data from the record. The path field consists of the path number and the segment number, and the node field structure consists of the structure position, field value, field source, etc. During the operation, first establish a path group according to the path field order. For example, if the path field is PD07-03, then set the group name to path PD07-03 group. In this group, summarize all node field structure contents from the same path field, read each structure field content one by one, and combine the field position and field value to form a mapping item. For example, if the first position is "planting land", the second position is "transferable", and the third position is "8 years", then generate the mapping item "1: planting land, 2: transferable, 3: 8 years". Then summarize the fields from small to large and write them into the extension path structure column corresponding to the path field. Then, confirm the plot number to which the data belongs based on the field source information recorded in the node field. For example, if a structure field is identified as PD07-03-DK51105, then the node content belongs to the plot number DK51 105. During the writing process, the path number and the plot number must be combined to generate a mounting identification field, such as PD07-DK51105. The corresponding field structure content is then mounted to the record unit under the identification field to ensure that the mounting records of the same plot under different paths are not overwritten. For the case of multiple paths converging for the same plot, for example, DK51105 appears in both PD07-03 and PD08-02, two mounting record items, PD07-DK51105 and PD08-DK51105, are generated respectively, and the path field content and node field structure are written respectively. The writing process needs to determine whether each record has a null value or incomplete field. If a field value is missing, it is marked with "empty" in the mapping item, such as "2: empty", indicating that the position is not filled. After the final convergence is completed, the mounting record generated by the combined path field and node field structure is marked as "Extended package path structure mounting record completed" status. It serves as the basic identifier for subsequent structure tracing and path extension, and the extended package path structure mounting record is obtained.

It then associates each authority field with the use field, use classification field, and operation mode field.

The path attachment module extracts the unit code field and extension period field information based on the data number with the adaptation status in the land parcel authority field adaptation result record, appends the path field content to the path table according to the direction logic mapped by the period segment, and then synchronously fills the corresponding values ​​of the purpose field and the authority field into the path node structure to obtain the extension path structure attachment record.
