Description

TECHNICAL FIELD

[0002] In recent years, ecological restoration, as a key link to promote high-quality development of land space and restoration of ecosystem function, has attracted widespread attention. Traditional ecological restoration relies on macro planning guidance and static evaluation model, which is difficult to finely depict the benefit distribution and dynamic response of restoration measures in spatial scale. Therefore, multi-source technologies such as geographic information system (GIS), remote sensing image analysis (RS), ecological simulation and artificial intelligence are gradually introduced into the process of ecological restoration, in order to enhance the modeling ability of the correlation between spatial pattern, ecological process and restoration effect. On this basis, the land space modeling method based on grid division gradually becomes the main means to construct regional restoration strategy, which provides a spatialized and structured operation basis for ecological restoration. Ecological response analysis method is also constantly enriched, from the initial qualitative index system to quantitative and time-series ecological parameter extraction, so that the causal relationship between ecological response and restoration intervention is more traceable and deducible.

[0003] However, there are still several key bottlenecks in the current ecological restoration intelligent analysis technology: first, the restoration strategy is often evaluated by a single grid, which lacks a conflict identification and coordination mechanism for regional linkage, especially in the cross-grid restoration path, there are problems such as redundant intervention or imbalance of strategy superposition, which fails to consider the structural conflict of path interaction between grids; second, the ecological response evaluation is generally oriented to immediate benefit, ignoring the time-lagged response law of ecological system, which cannot accurately identify the benefit diffusion path of restoration measures in time dimension; third, there is a lack of hedging mechanism based on the overall structure of ecological system, which is difficult to implement hierarchical and priority-driven compensatory restoration decisions for conflict paths.

[0022] In order to make the above-mentioned purposes, features and advantages of the present application more apparent and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings of the specification.

[0023] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from the description, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited by the specific embodiments disclosed below.

[0024] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an independent or selective embodiment that excludes other embodiments.

[0025] As described in the above background, the current ecological restoration intelligent analysis technology still has several key bottlenecks: first, the restoration strategy is often evaluated as a single grid, lacking a conflict identification and coordination mechanism for regional linkage, especially in the cross-grid restoration path, there are problems such as redundant intervention or strategy imbalance, and the structural conflict of path interaction between grids is not considered; second, the ecological response evaluation is generally oriented to immediate benefits, ignoring the time-lagged response law of the ecological system, and unable to accurately identify the benefit diffusion path of the restoration measures in the time dimension; third, there is a lack of hedging mechanism based on the overall structure of the ecological system, and it is difficult to implement hierarchical and priority-driven compensatory restoration decisions for conflict paths.

[0026] Figure 1 The flowchart of the land space ecological restoration intelligent analysis method according to the embodiments of the present application. As shown in Figure 1 In the land space ecological restoration intelligent analysis method, it includes: S1: Based on the grid unit of territorial space, extract the parameters corresponding to the current policy unit in each grid unit, and construct the policy structure set; and generate the repair path conflict profile vector set between each pair of adjacent grid units.

[0027] Firstly, the spatial division system in the analysis area needs to be standardized. The territorial space is divided into regular or irregular basic grid units, each of which has a unique number identification in two-dimensional or three-dimensional coordinate system. In each grid unit, the records of ecological restoration activities in the region over the years need to be extracted, including artificial intervention (such as land consolidation, vegetation restoration) and natural process guidance (such as hydrological regulation, natural enclosure) etc.

[0028] S1.1: Construction of policy structure set.

[0029] Under the grid unit division structure of territorial space, based on historical restoration engineering archives and remote sensing intervention records, the types of ecological restoration tasks that have occurred in each grid unit are coded to construct a repair task label set ; each repair task label corresponds to a specific intervention type and execution phase identifier.

[0030] Based on the repair task label set, the task labels in each grid unit are grouped according to the spatial overlap range and execution time period, and the intervention method and target object are recorded to construct the policy structure set , where each policy unit contains spatial coverage coding, time period vector and intervention object parameters. Specifically, based on the analysis of each label in the repair task label set according to the time period and spatial influence range in the grid unit, the task labels with spatial overlap or the same target object in the same time period are identified, and the structured policy unit is constructed accordingly.

[0031] The policy structure set is integrated according to the grid number sequence, that is, all policy units under each grid unit are uniformly coded and stored, and the corresponding grid number and coordinate information are bound to form the policy structure set of the global grid unit . This structure set has the ability of horizontal comparison and vertical evolution analysis, and is the basic data set for subsequent repair path conflict identification.

[0032] It should be noted that the current restoration activities in the territorial space have a high fragmentation characteristic, and a single intervention behavior often does not have the linkage of the ecosystem level. The strategy structure set can unify the spatio-temporal continuity, providing data standardization support for subsequent response chain modeling and conflict prediction.

[0033] S1.2: Generation of repair path conflict profile vector set.

[0034] For each pair of adjacent grid cells in the strategy structure set , extract the respective strategy cells and the corresponding spatial boundary, and construct a boundary vector pair set ; wherein each boundary vector pair represents a combination of boundary vectors of two strategy cells, and each boundary vector pair represents a possible intervention interface of a pair of strategy cells on the spatial boundary.

[0035] For each boundary vector pair , extract the intersecting boundary line segment or overlapping buffer segment (using a vector intersection algorithm, such as the fast rectangular boundary screening + segmented scan line method to extract the spatial overlapping region), and record it as a boundary conflict point set , wherein each is the boundary conflict spatial representation of the boundary vector pair . If the overlapping length between two strategy cells is not less than the preset length threshold, it is judged that there is physical contact or influence extension.

[0036] Combine the boundary conflict point set and the intervention time period parameters of the strategy cells and , calculate the time period overlap value between each pair of strategies, and construct a conflict profile vector , which is summarized into a repair path conflict profile vector set .

[0037] For example, the calculation of the time period overlap value between each pair of strategies can be as follows: Obtain the spatial boundary conflict point set between the corresponding two strategy cells in the repair path conflict profile vector set, as well as the corresponding two intervention time periods and ; According to the two intervention time periods, calculate the time period overlap length : ; Further calculate the time period joint length : ; Accordingly, the time period overlap degree is calculated as the time period overlap length minus the time period joint length .

[0038] The calculation of the spatial conflict intensity is the absolute value of the size of the spatial boundary conflict point set divided by the absolute value of the size of the entire boundary point set (the union of the boundary point sets of the two grid cells). The time period overlap degree and the spatial conflict intensity are weighted to obtain the time period overlap value between each pair of strategies .

[0039] For example, if the size of the two spatial boundary conflict point sets is 24 and the size of the entire boundary point set is 120, the spatial conflict intensity is ; wherein the intervention time period of the repair strategy unit and is and respectively, the overlap length of the two time periods is , which is ; the joint length of the time periods is : ; accordingly, the time period overlap degree is ; assuming that the time and space conflict weighting coefficient is 0.6, the final comprehensive time period overlap degree is: .

[0040] S2: According to the natural resource succession logic, combined with the repair target label set on each grid unit, the ecological restoration benefit chain structure is constructed, wherein each element corresponds to the ecological response node of the repair target label set, and the response data sequence set corresponding to each ecological response node is extracted.

[0041] Firstly, according to the established repair task label set of each grid unit, the succession dependence matrix is constructed according to the dependence evolution order between natural resource types (such as water body restoration prior to vegetation growth), and the element of the matrix represents the dependence direction and priority level of the repair task label to .

[0042] Specifically, the succession dependence matrix is a directed weighted matrix, if the element , it means that the repair task label has no clear dependence on ; if , it means that the ecological response effect of depends on the completion of the repair task of , and the larger the value is, the stronger the dependence is or the higher the priority is.

[0043] The construction of this matrix is based on the multi-source fusion ecological succession rule library. According to the principles of ecology and long-term field investigation results, this rule library defines the repair order of common ecological factors, for example: water connectivity restoration → soil stability improvement → vegetation natural regeneration; wetland function restoration → water bird habitat reconstruction; ground micro-topography reconstruction → biological community succession formation.

[0044] The rule matching mechanism based on the ontology and the expert rule fusion is adopted, the factor types (such as water body, soil, woodland, wild life and the like) corresponding to intervention objects in labels are mapped, and the dependent path is searched in the factor succession ontology tree, so that whether there is a dependent relationship between labels is determined, and a corresponding priority level is given, and the construction of the succession dependent matrix makes the subsequent establishment of the ecological response chain have clear directionality and order control ability, and the problems of independent processing of ecological factors and ignoring the overall succession logic of the ecological system in the traditional analysis method are solved from the root.

[0045] Based on the succession dependent matrix , the repair target label path with a directed dependent relationship is extracted, the repair target labels are numbered in the repair target label path according to the order, and the ecological restoration benefit chain structure is constructed , wherein each element is an ecological response node.

[0046] Specifically, a topological sorting algorithm (such as Kahn algorithm or DFS backtracking method) is used to identify branch paths of a directed graph formed by the dependent matrix, and a directed path set from a source task (no predecessor dependent) to a target task (no successor dependent) is extracted, wherein each path represents a logically feasible repair response order.

[0047] The ecological restoration benefit chain structure is essentially a directed layered chain network, each chain represents a possible ecological process repair path, and each node is a logical connection point of an ecological target response. The structure supports tracking the ecological benefit progressive relationship according to the path, and can also be used as a conflict discrimination basis in strategy adjustment.

[0048] It should be noted that the present application orders the spatially distributed repair target labels through the internal succession mechanism of the ecological system, establishes a response path across time and factors, so that subsequent ecological simulation and prediction can be based on chain reasoning rather than point regression, and the causal completeness of the overall ecological analysis is improved.

[0049] Further, for each ecological response node, the remote sensing index sequence, the ground survey data or the ecological simulation result related to the repair task label in the corresponding grid cell are extracted to form a response data sequence, and the response data sequence set D is formed.

[0050] The remote sensing ecological index sequence is derived from the interpretation of multi-period remote sensing data for the corresponding grid units of nodes, including ecological indicators such as near-infrared vegetation index, soil moisture index, wetland distribution index, and built-up area identification index. The surface ecological survey data sequence includes, if ecological survey quadrats are located in the grid unit, or if field sampling records are provided by the regional management unit, surface measured data can be organized in time series, such as soil pH, water content, organic matter, biodiversity index, and habitat suitability index. This type of data is in structured tabular form and needs to be uniformly normalized into a time series after data preprocessing. Ecological simulation results include, when sufficient remote sensing and measured data are lacking, the ecosystem process model (such as InVEST, PLUS, or CLUE-S) can be used to simulate the time evolution process based on the input parameters of the strategy unit, extracting the model's predicted output indicators (such as hydrological flux, biomass accumulation, etc.) as part of the response data sequence. This type of data requires accompanying descriptions of the model source and input parameters to ensure data reliability.

[0051] In summary, this invention can clearly define the ecological causal sequence between restoration tasks, thereby generating a structured ecological restoration benefit chain. This benefit chain structure enhances the modeling ability of causal impact transmission paths in ecosystems, making it easier to identify key response nodes and weak links. At the same time, by extracting the remote sensing or simulation data sequence corresponding to each response node, a response dataset can be systematically established, which is beneficial for realizing time-series tracking and comparative evaluation of the effects of ecological intervention.

[0052] S3: Based on the strategy unit structure set and response data sequence set, calculate the trace intensity index of each strategy unit, and combine the response time difference of the preceding and following ecological response nodes in the ecological restoration benefit chain structure to construct a set of delayed response paths.

[0053] The calculation of the traceability intensity index for each strategy unit includes: strategy structure set Each strategy unit and response data sequence set The corresponding response data sequence Perform one-to-one pairing to construct a strategy-indicator mapping set; For each pair in the strategy-indicator mapping set For the response data sequence In the strategy unit The slope, magnitude, and duration of the change within the intervention period are weighted and integrated to generate the corresponding trace intensity index. .

[0054] The slope of change can be calculated using linear regression or local trend analysis; the amplitude is the range between the maximum and minimum values; and the duration is the length of a time slice where the rate of change is not less than a preset response threshold. These three factors are weighted and integrated according to weighting coefficients. This trace intensity index characterizes the degree of significance that the strategy unit has on the response chain in both spatial and temporal dimensions.

[0055] Furthermore, the construction of the delayed response path set includes: Based on the ecological restoration benefit chain structure Adjacent ecological response node pairs For the response data sequence and Calculate the response center offset value And combined with the trace strength index Perform a difference comparison, if the following conditions are met yes direct or indirect downstream nodes, and If the path segment exhibits delayed behavior, then delayed path elements are constructed. Forming a set of delayed response paths .

[0056] Among them, the response center offset value The calculation includes: calculating the weighted center time of two response data sequences (time average weighted by data values); and calculating the absolute difference between the two weighted center times to obtain the response center offset value. Additionally, for any pair of response nodes in the ecological restoration benefit chain structure, if... Not For direct or indirect downstream nodes, the response center offset value is not calculated, and the corresponding node pairs are not included in the hysteresis path analysis.

[0057] In summary, this invention, by pairing strategy structures with ecological response sequences one-to-one, extracts the slope, amplitude, and duration of response changes within the intervention period, and constructs a trace intensity index, enabling quantitative characterization of the strength and delay characteristics of ecological intervention effects. Furthermore, based on the difference in response center offset between adjacent response nodes in the ecological restoration benefit chain, and combined with the trace index, directional determination is made, identifying lagging paths only when the subsequent node exhibits a significant delay compared to the preceding node and the response intensity is weaker, effectively avoiding misjudgment. This mechanism strengthens the temporal consistency constraint of the ecological causal chain, providing a scientific basis for constructing a set of response lag paths and subsequent compensation scheduling.

[0058] S4: Construct a repair conflict hedging matrix based on the repair path conflict profile vector set and the delayed response path set; based on the hedging level in the repair conflict hedging matrix, coordinate and schedule the compensatory repair task plan of the corresponding grid unit, and prioritize the strategy of compensating upstream nodes in the benefit chain.

[0059] S4.1: Fix the construction of the conflict hedging matrix.

[0060] Repair path conflict profile vector set Each group of conflict items and delayed response path set Lag path elements Perform pairing, for each pair Calculate spatial overlap rate and response chain interference factor to generate hedging grade score. Forming a conflict-repairing hedging matrix .

[0061] Among them, hedging rating The calculations include: Extract conflict items from each group separately and delayed path elements For the corresponding spatial range, calculate the ratio of the overlapping area to the merged area to obtain the spatial overlap rate of the two spatial ranges; By dividing the value 1 by 1 + response center offset value Obtain the response chain interference factor; The hedging rating is obtained by weighting the spatial overlap rate and the response chain interference factor.

[0062] Fill all the hedging ratings into the matrix in sequence to complete the construction of the conflict hedging matrix.

[0063] S4.2: Based on the hedging level in the conflict hedging matrix, coordinate and schedule the compensatory repair task plan of the corresponding grid unit.

[0064] Based on the ecological restoration benefit chain structure Each ecological response node The ecological impact weight is assigned based on the position of the nodes, with those located at the beginning of the ecological restoration benefit chain (such as water purification nodes) given higher weights to reflect their priority in the transmission of benefits to the overall restoration chain.

[0065] According to the repair conflict hedging matrix Medium hedge rating With corresponding ecological response nodes The product of the ecological impact weights is used to calculate all joint scores, and the joint priority matrix is ​​constructed by sorting them in descending order of size.

[0066] It should be noted that only when the conflict profile vector item and the lag path response interval exist a time period overlap, the subsequent hedge level score calculation can be carried out.

[0067] According to the joint priority matrix, the highest priority repair path and the corresponding grid unit are identified, and the matched compensatory repair task label is screened out in combination with the lag path element of the lag response path, and is included in the compensation task plan set.

[0068] All compensatory repair tasks included in the compensation task plan set are reordered according to the topological order of the associated ecological response node in the ecological restoration benefit chain. The specific operation is: based on the numbering order of each node in the ecological benefit chain structure, a task dependency graph is constructed. For each compensation task, the corresponding response node number is extracted as the serial number identifier in the topological graph. By executing the topological sorting algorithm in the task scheduling process, an execution queue that meets the ecological causality logic can be obtained, ensuring that the compensation tasks corresponding to the previous response nodes are scheduled and implemented in time, thereby effectively guaranteeing that the subsequent response nodes have a reliable ecological prerequisite condition.

[0069] In combination with the priority score of the compensation task (obtained by multiplying the hedge level and the response node weight), the task priority is further refined and sorted within the pre-order-post-order topological sequence. That is: under the premise of meeting the ecological succession order, tasks with higher score values are preferentially executed to maximize the ecological restoration benefit recovery speed per unit time. This double-layer sorting mechanism can achieve the optimal arrangement of compensation tasks in the two dimensions of causality dependence and weight value, avoiding the problem of invalid intervention of the post-node due to the non-restoration of the pre-ecological node in the strategy scheduling, thereby improving the continuity and response synergy of the overall ecological response link.

[0070] The scheduling system can dynamically issue or recommend compensation tasks for the corresponding grid unit based on this list in combination with regulation and control resource constraints, timing control parameters and other information, thereby repairing the lag path chain breakage and improving the overall benefit chain stability of ecological restoration.

[0071] As can be seen, the present application constructs a quantifiable hedge level score model through a space-time-response three-domain joint matching mechanism, realizes lag breakage identification on the chain according to the response chain interference factor, solves the problem of ignoring the ecological response chain structure in traditional strategy conflict processing, and constructs a scheduling mechanism based on joint priority, strengthens the principle of preferential repair of ecological pre-node, and improves the conduction efficiency of the overall intervention.

The trace analysis unit is configured to calculate a trace strength index of each strategy unit based on the strategy unit structure set and the response data sequence set, and construct a lag response path set in combination with a response time difference between front and rear ecological response nodes in the ecological restoration benefit chain structure.
