Description

Technical Field

[0001] This invention relates to the field of land planning, and in particular to a method and system for planning the spatial utilization of land resources. Background Technology

[0002] With the increasing demand for diversified urban functions and refined governance, the spatial utilization of land resources is gradually becoming more diversified and dynamic. In addition to traditional long-term fixed-use planning, forms such as temporary land use, phased activity land use, and time-sharing land use are constantly emerging, including night market areas, temporary exhibition venues, emergency resettlement sites, seasonal storage yards, and temporary parking lots. These types of land use are characterized by short time spans, large variations in usage intensity, and complex influencing factors, placing higher demands on existing land spatial planning and management methods.

[0003] Existing land resource spatial use planning methods typically focus on static spatial structure optimization, primarily configuring and zoning based on plot attributes, land use types, and long-term functional positioning, lacking the ability to systematically model the time dimension. When faced with temporary land use events with clearly defined start and end times and dynamic impact intensity, traditional methods often rely on manual approval or experience-based judgment, resulting in the following shortcomings: a lack of a unified "spatiotemporal unit" expression mechanism, making it difficult to differentiate and dynamically manage the same spatial unit across different time periods; a disconnect between temporary land use approval and spatial planning data, with conflict verification relying on manual overlay analysis, leading to low efficiency and insufficient consistency; the absence of rule trigger records and version tracking mechanisms, resulting in poor traceability of the approval process and hindering subsequent review and supervision; and insufficient ability to identify risks and assess priorities for temporary land use, making it difficult to automatically identify key monitoring units and generate inspection paths. Therefore, this paper proposes a land resource spatial use planning method and system to improve the scientific nature of planning decisions, dynamic adaptability, and regulatory traceability. Summary of the Invention

[0004] The main objective of this invention is to provide a method and system for planning the spatial utilization of land resources, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A method and system for land resource spatial use planning includes the following steps:

[0007] S1. Obtain relevant data for the planning area and perform standardized processing;

[0008] S2. Construct a set of spatiotemporal land use units that include the time dimension based on the time division strategy;

[0009] S3. Receive temporary land use event input information and map it to the corresponding spatiotemporal land use unit;

[0010] S4. Based on preset constraint rules, perform conflict verification on the spatiotemporal land use units to generate a permit determination result;

[0011] S5. Score and rank the candidate solutions that pass the conflict check and generate recommended deployment results;

[0012] S6. Output temporary land use permit results, control list, and audit log.

[0013] Furthermore, the relevant data for the planning area includes at least basic spatial data, sensitive constraint data, and dynamic monitoring data;

[0014] The basic spatial data includes land parcel boundary data, road network topology data, and building outline data; the sensitive constraint data includes fire lane data, important facility distribution data, and control boundary data; the dynamic monitoring data includes traffic operation status data, pedestrian density data, or historical law enforcement record data; and the standardization process includes coordinate unification, accuracy correction, attribute field mapping, and data version identification.

[0015] The attribute field mapping includes unifying land use codes and time tags from different sources into a preset classification system, and the data version identifier is used to record the data change trajectory of different planning periods or different collection batches.

[0016] Furthermore, the spatiotemporal land use unit is represented as ,in Indicates the spatial unit number, Indicates the time period number;

[0017] The time period number is generated based on a time division strategy, which includes one or more combinations of division by hour, by weekdays and non-weekdays, by holidays, or by seasonal windows; and an initial status label is set for each spatiotemporal land use unit, which includes a pending status, a pre-restricted status, or a pre-prohibited status.

[0018] The conflict verification step performs a secondary determination on the spatiotemporal land use unit based on the initial state label and preset constraint rules, so as to update the initial state label to the final permitted state.

[0019] Furthermore, the temporary land use event includes at least a start time, an end time, scale parameters, and a set of impact types; the set of impact types includes at least one of noise impact, pedestrian density impact, vehicle access impact, or environmental disturbance impact.

[0020] Let the number of elements in the set of influence types be... The influence factor vector is then expressed as:

[0021]

[0022] in, Indicates the first The influence intensity values ​​corresponding to each influence type; and ;

[0023] The corresponding time period number is determined based on the start and end times. This maps temporary land use events to spatiotemporal land use units. The influence factor vector mentioned above It can be used as an input parameter for soft constraint rules in the conflict verification step, or for weighting and adjusting environmental sensitivity indicators in the scoring and ranking step.

[0024] Furthermore, the preset constraint rules include hard constraint rules and soft constraint rules; the hard constraint rules are used to generate a pass or fail determination result, and at least include fire evacuation distance threshold rules, fire lane continuity rules, minimum distance rules for sensitive facilities, and traffic service level lower limit rules; the soft constraint rules are used to generate restrictive execution conditions, and at least include noise time period restriction rules, entrance and exit number restriction rules, and garbage collection capacity matching rules.

[0025] The threshold or constraint strength of the soft constraint rule varies with the influence factor vector. The value is adaptively adjusted.

[0026] Furthermore, the scoring and ranking adopts a spatiotemporal suitability scoring function as follows:

[0027]

[0028] in, Indicates the candidate scheme number; Indicates the number of evaluation indicators; Indicates the first The weight coefficients of each evaluation indicator, and satisfying

[0029]

[0030] Indicates the first The normalized values ​​of each indicator; ;

[0031] The evaluation indicators include at least accessibility indicators, traffic disturbance indicators, safety compliance margin indicators, and environmental sensitivity indicators.

[0032] The normalized value or weight of the environmental sensitivity index mentioned above. Based on the impact factor vector The revisions will be made to reflect the differentiated environmental constraints imposed on various temporary land use events.

[0033] Furthermore, the candidate schemes Calculate the risk priority index:

[0034]

[0035] in, Indicates the number of constraint rule clauses; Indicates the first The severity coefficient of the rule; Representation scheme For the first Risk metric for each rule;

[0036] The risk metric is determined based on a threshold margin, when a preset threshold is reached. At that time, the threshold margin is:

[0037]

[0038] in For the plan The actual indicator value; when At that time, the risk metric Depend on The comparison result with the zero threshold is determined; and when Less than the preset safety margin threshold or when and When the zero threshold condition is violated, the corresponding spatiotemporal land use unit will be marked as a key supervision unit, and a key supervision list or inspection route will be generated accordingly.

[0039] Furthermore, to reflect the differences in adaptation to the same spatial unit across different time periods, a time period adaptation function is defined:

[0040]

[0041] in Indicates the first The spatial unit in the first Time period suitability Indicates capacity matching degree, Indicates the probability of conflict or the intensity of interference. and The weighting coefficients are satisfied. ;

[0042] in and All values ​​are dimensionless values ​​after normalization.

[0043] The time period adaptation is used to adjust the priority of candidate spatiotemporal land use units or to correct the weight parameters in the scoring and ranking process based on time periods.

[0044] A land resource spatial use planning system, comprising:

[0045] The data access and management module is used to acquire data for the planning area and establish a data version control and update mechanism.

[0046] The spatiotemporal unit construction module is used to generate spatiotemporal land use units containing initial state labels according to the time division strategy, and supports the updating of the initial state labels to the final permit state.

[0047] The event modeling module is used to receive temporary land use events, determine the corresponding time window, generate impact factor information, and transmit it to the rule engine.

[0048] The constraint rule engine module is used to perform spatial overlay analysis and threshold comparison analysis, and output the trigger rule number, trigger location element and threshold comparison difference;

[0049] The scheme generation module is used to generate candidate deployment schemes and form licensing recommendations.

[0050] The sorting and risk assessment module is used to sort candidate solutions and generate key regulatory unit tags and key regulatory lists;

[0051] The Output and Audit module is used to output license results, control lists and audit logs, and supports result backtracking and review.

[0052] A computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the above-described method steps.

[0053] The present invention has the following beneficial effects:

[0054] Compared with existing technologies, this solution constructs spatiotemporal land use units that include a time dimension, enabling the differentiation and dynamic updating of the state of the same spatial unit at different time periods. This structurally overcomes the problem that traditional static land management methods cannot reflect time differences. By establishing a temporary land use event model that includes an impact factor vector, different types of temporary activities can be adaptively adjusted according to their impact intensity during conflict verification and scoring ranking stages, improving the matching degree between planning results and activity characteristics. By distinguishing between hard and soft constraint rules, it achieves flexible control over the intensity of use and execution conditions while ensuring bottom-line requirements such as fire safety, traffic access, and protection of sensitive facilities, thus achieving a balance between safety and utilization efficiency. Finally, by introducing a spatiotemporal suitability scoring function, candidate schemes are comprehensively evaluated using multiple indicators. This approach transforms planning decisions from a single threshold judgment to a weighted ranking decision, improving the scientific rigor and comparability of scheme selection. By constructing a risk priority index and threshold margin calculation mechanism, high-risk units are automatically identified and key monitoring lists or inspection routes are generated under critical conditions, enhancing the application of planning results in regulatory and enforcement scenarios. By defining a time-period adaptability function to quantitatively correct the capacity matching degree and conflict probability of spatial units in different time periods, the planning results possess time sensitivity and dynamic adjustment capabilities. Simultaneously, by establishing a data version identification and audit log mechanism, the entire planning process is tracked and results are traceable, improving the transparency and reliability of planning decisions. This forms a data closed loop between spatial planning, temporary land use approval, and subsequent supervision, improving the level of refined management of land resource spatial utilization.

[0057] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0058] Example 1

[0059] The present invention will be described in detail below with reference to embodiments. This embodiment uses the spatial utilization planning of temporary nighttime business activities in urban commercial areas as an application scenario, but the present invention is not limited to this specific scenario.

[0060] First, relevant data for the planning area are acquired, including basic spatial data, sensitive constraint data, and dynamic monitoring data.

[0061] Basic spatial data is used to describe the boundaries of land parcels, road network structure, and building distribution; sensitive constraint data is used to identify fire lanes, important public facilities, and planning control boundaries; dynamic monitoring data is used to reflect traffic operation status, pedestrian flow distribution, and historical management records.

[0062] The above data undergoes unified coordinate transformation, attribute standardization, and accuracy correction. A data version management mechanism is established to record the source, time, and content of data updates, ensuring the integrity and traceability of the planning basis.

[0063] The planning area is divided into several spatial units, and each spatial unit is assigned a unique number.

[0064] Based on a preset time division strategy, time is divided into several time periods, such as by hour, weekdays and non-weekdays, holidays, or seasonal windows.

[0065] By combining spatial units with time periods, spatiotemporal land use units are formed. This is used to indicate the usage status of a spatial unit within a specific time period.

[0066] An initial state label is assigned to each spatiotemporal land use unit. The initial state label includes a pending state, a pre-restricted state, and a pre-prohibited state. The initial state label is generated based on historical data and basic planning rules, and is updated during subsequent conflict verification.

[0067] When a temporary land use application is received, the application is modeled as an event.

[0068] The temporary land use event shall include at least the start time, end time, scale parameters, and set of impact types.

[0069] The impact type set describes the categories of impacts that the activity may have on the surrounding environment, such as noise impact, pedestrian density impact, or vehicle access impact.

[0070] The corresponding time period number is determined based on the start time and end time, and the event is mapped to the corresponding spatiotemporal land use unit.

[0071] The impact type information is used in the subsequent rule engine to dynamically adjust the constraint strength of soft constraint rules.

[0072] Conflict checking includes spatial overlay analysis and rule comparison analysis.

[0073] First, the spatial overlap between the land use unit and fire lanes, prohibited areas, and planning control boundaries is assessed. If overlap or encroachment occurs, the application is immediately rejected.

[0074] Secondly, the traffic impact, evacuation capacity, and environmental disturbance of the candidate schemes were compared against relevant rules.

[0075] When a hard constraint rule is violated, the application is directly deemed unsuccessful; when only a soft constraint rule is triggered, restrictive control conditions are generated, such as limiting operating hours, controlling scale, or adjusting the layout of entrances and exits.

[0076] After the conflict verification is completed, the initial status label will be updated to the final licensed status.

[0077] For a spatiotemporal land use unit that passes the conflict check, multiple candidate deployment schemes are generated within it.

[0078] The layout plan includes parameters such as the stall layout, entrance and exit locations, reserved locations for emergency passages, and the arrangement of garbage collection points.

[0079] A spatiotemporal land use unit can correspond to multiple candidate schemes for subsequent sorting and screening.

[0080] A comprehensive evaluation of each candidate solution was conducted.

[0081] The evaluation indicators should include at least accessibility indicators, traffic disturbance indicators, safety compliance margin indicators, and environmental sensitivity indicators.

[0082] After standardizing each indicator, a comprehensive score is generated through weighting.

[0083] Impact type information can be used to adjust the weights of environmental sensitivity indicators, so that the scoring results can reflect the differentiated requirements of different activity types.

[0084] Candidate solutions are ranked based on comprehensive scores, and recommended deployment solutions are generated.

[0085] After the schemes are sorted, the differences between each candidate scheme and the preset rules are analyzed.

[0086] When certain rule indicators approach the preset safety threshold or pose potential risks, the corresponding spatiotemporal land use unit will be marked as a key monitoring unit.

[0087] Key monitoring units are ranked according to their risk level, and patrol routes are generated based on the road network structure for subsequent patrol work by management departments.

[0088] To reflect the differences in the use of the same spatial unit at different time periods, a comprehensive assessment of the capacity matching and conflict probability of each spatiotemporal land use unit is conducted.

[0089] By using preset weights, the capacity matching degree and the conflict probability are linearly combined to form a time period fit index.

[0090] This fit is used to adjust the priority of candidate units or adjust the scoring weights, thereby improving the time sensitivity of the planning results.

[0091] The final output includes: temporary land use permit results; control list; recommended layout layers; and audit logs.

[0092] The audit log records the data version number, rule triggering status, execution parameters, and time information, enabling full-process traceability management.

[0093] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
