Technical Field
[0001] This invention belongs to the field of mine ecological restoration technology, specifically relating to a method for predicting the effects of mine ecological restoration. Background Technology
[0002] With the deepening of ecological civilization construction, mine ecological restoration has become a core task for the transformation of resource-based cities and the ecological protection and restoration of national land space. In recent years, the concept of ecosystem reference has been introduced into mine restoration practice. By comparing the ecological parameters of stable zones in natural succession, quantifiable restoration targets are set for damaged mining areas. Mine ecological restoration can not only effectively restore the ecosystem function of mining areas and improve the quality of the regional ecological environment, but also directly affect the quality of life of residents around mining areas and the protection of biodiversity. With the continuous improvement of national requirements for ecological and environmental protection, establishing a precise, dynamic, and quantifiable prediction system for the effects of mine ecological restoration has become an urgent need for the industry.
[0003] Existing methods for predicting the effects of mine ecological restoration suffer from the following shortcomings: First, most methods rely on forward extrapolation based on predetermined restoration measures, resulting in weak guidance for optimizing the proposed solutions. Second, existing technologies often treat the restoration area as a homogeneous whole, neglecting the network-level recovery gain brought about by the self-organization process between internal patches. Finally, existing methods lack a dynamic correction mechanism based on real-time monitoring information gain, causing restoration measures to fail to respond to actual changes, making it difficult to guarantee long-term effectiveness and cost-effectiveness. Therefore, this invention proposes a method for predicting the effects of mine ecological restoration. It establishes a goal-oriented method for calculating the intensity of restoration measures through an inverse ecological trajectory equation, quantifies the synergistic gain between natural resilience and human intervention through patch network analysis, and achieves precise control of the restoration process through a hybrid prediction model and dynamic correction. This significantly improves prediction accuracy and feasibility, providing scientific decision support for mine ecological restoration. It is of great significance for promoting technological progress in the industry, improving restoration efficiency, and reducing restoration costs, while also providing technical support for national ecological civilization construction and sustainable mine development. Summary of the Invention
[0004] The purpose of this invention is to provide a method for predicting the effects of mine ecological restoration.
[0005] To achieve the above objectives, the present invention is implemented according to the following technical solution: This invention includes the following steps: Acquire multi-source ecological monitoring data and historical restoration data, construct a current ecological state vector, construct a reference ecosystem database to match the reference ecosystem, and extract the target ecological state vector; Establish an inverse ecological trajectory equation, calculate the expected measure intensity, expected ecological state vector, and inverse trajectory deviation, and adjust the expected measure intensity based on the inverse trajectory deviation to determine the initial restoration plan; The mine restoration area is divided into different patches and the functional groups of each patch are determined. A natural invasion model is constructed, the comprehensive index of natural resilience and the network-level natural invasion gain are calculated, and target optimization is carried out to obtain supplementary restoration schemes. Determine a complete restoration plan and calculate intervention indicators. Combine the current ecological state vector and the comprehensive index of natural resilience to construct a hybrid prediction model, and output the state vector of the restoration process, the time-varying confidence matrix of each indicator and the prediction interval. Calculate the positive prediction bias and the monitoring information gain of each patch, determine the objective function of the remediation measures in combination with the remediation cost, determine the final remediation plan, obtain real-time monitoring data to calculate the relative bias, and perform dynamic correction. The ecological monitoring data includes space-based data, air-based data, and ground-based data; The historical repair data includes repair measures, measure intensity, repair cycle, and repair cost; The ecological state vector includes core parameters for ecological restoration; these core parameters include vegetation coverage, soil organic matter content, biodiversity index, soil retention capacity, water conservation capacity, comprehensive heavy metal pollution index, and geological disaster hazard elimination rate. The reverse ecological trajectory equation includes natural ecological process terms, intervention measures terms, environmental stress terms, and reverse goal-driven terms.
[0006] Furthermore, the matching reference ecosystem method includes: Historical restoration data from surrounding natural succession stable areas, near-natural restoration demonstration areas, and historically successful restoration areas were collected to construct a reference ecosystem database. Meteorological metadata vectors, geographic metadata vectors, soil metadata distribution, ecological structure data matrix, and disturbance history feature sets were extracted and standardized. Unique thermal coding was used to eliminate differences in dimensions and types. The disturbance intensity index of the current mine restoration area is calculated, and the similarity calculation priority is determined according to the disturbance intensity. The screening threshold is adaptively calibrated using the quantile method based on the reference ecosystem database. Calculate the Jaccard similarity coefficient for the set of historical features of interference, calculate the Mahalanobis distance for the meteorological metadata vector, calculate the Euclidean distance for the geographic metadata vector, and take the union to obtain the rigid constraint candidate set; Within the rigidly constrained candidate set, the Earth's movement distance is calculated for the distribution of soil metadata, and the structural similarity index is calculated for the ecological structure data matrix. The combined constraint conditions are then used to obtain a comprehensive weighted candidate set. The linear coefficient is dynamically adjusted based on the completeness of the data in the mine restoration area. The linear combination method is used to integrate entropy weight and analytic hierarchy process weight to calculate the comprehensive similarity index of each reference sample point in the comprehensive weighted candidate set. A preset number of reference sample points are selected in descending order as the reference ecosystem. The core parameters of ecological restoration, climate parameters, geographical parameters, soil parent material parameters and time parameters of each reference sample point are extracted and weighted averaged to obtain the target ecological state vector.
[0007] Furthermore, the method for determining the initial repair plan includes: Based on multi-source ecological monitoring data and historical restoration data, a differential equation for the forward ecological restoration process is constructed. By inverse time transformation and the introduction of an inverse target traction term, an inverse ecological trajectory equation is established. Set the inverse integration step size, take the target ecological state vector as the initial condition, use the fourth-order Runge-Kutta numerical integration to obtain the inverse trajectory and calculate the state change rate at each time step; By rearranging terms of the inverse ecological trajectory equation and substituting them into the expression for the intervention term, the expected intensity of the intervention is derived from the response function of the intervention. This response function is then mapped to the intensity of the intervention in the forward time. Substituting this into the differential equation of the forward ecological restoration process, the expected ecological state vector is obtained by integrating the equation with the current ecological state vector as the initial condition. The reverse trajectory deviation is calculated based on the expected ecological state vector and the target ecological state vector. Based on the reverse trajectory deviation and the preset threshold, the intervention index parameters are adjusted to determine the initial restoration plan. The initial restoration plan includes the intensity of the measures, the restoration period, the target state, the lower limit of the structure, the patch configuration, and the timing of the initial measures.
[0008] Furthermore, the method for constructing the natural invasion model includes: Based on the structural lower limit and initial measure sequence in the initial remediation plan, and combined with differences in topography, soil parent material and microclimate, the mine remediation area is divided into different patches and patch configuration vectors are extracted; the patch configuration vectors include patch area, distance to the nearest natural source, corridor connectivity, edge effect ratio, and microhabitat heterogeneity index; Based on the community composition, species niche characteristics, and interspecific functional complementarity of the reference ecosystem, the configuration vector of each patch is matched with the functional group suitability matrix of the reference ecosystem to determine the functional group configuration of each patch; the patch functional groups include nitrogen-fixing plant functional groups, deep-rooted soil-fixing plant functional groups, pollination network key species functional groups, surface crust functional groups, and litter decomposer functional groups. By applying the reverse principle of island biogeography, a dynamic equation for the number of naturally settled species in functional groups within a patch is established, and a natural invasion model is constructed. By introducing the time-lag coupling effect between InSAR surface deformation monitoring data and vegetation index, an InSAR deformation-vegetation index time-lag coupling correction factor is constructed and embedded into the natural invasion rate model to correct the prediction results.
[0009] Furthermore, the method for obtaining the supplementary repair solution includes: The steady-state number of naturally settled species is determined based on the steady-state conditions of the dynamic equation, and the comprehensive index of natural resilience for each patch is calculated. The network-level natural intrusion gain is determined based on the spatial distribution of the comprehensive index of natural resilience of each patch and the network effect of corridor connectivity. With the goal of maximizing the network-level natural intrusion gain, the optimization algorithm is used to solve the problem in combination with constraints. The supplementary repair scheme is determined based on the mapping relationship of measures. The supplementary repair scheme includes the addition of measures in time sequence, optimization of spatial configuration, adjustment of the natural-human intervention ratio, and a confidence matrix.
[0010] Furthermore, the method for constructing the hybrid prediction model includes: The initial repair plan and the supplementary repair plan are integrated to obtain a complete repair plan, and the intervention indicators of the complete repair plan are calculated. A hybrid prediction model was constructed, which extracted the initial ecological state vector, complete measures and plans, environmental factors and the whole process observation trajectory of completed mine restoration cases from historical restoration data to form a comprehensive set. The comprehensive set was randomly divided into a training set and a validation set in a ratio of 7:3. The hybrid prediction model includes an ecological process mechanism layer, an adverse target traction layer, a temporal attention residual correction layer, and an uncertainty quantification layer. It also uses a physical information neural network to embed physical laws and ecological principles into the loss function in the form of soft constraints. The ecological process mechanism layer introduces a comprehensive natural resilience index to correct the natural ecological process terms based on the differential equation of the positive ecological restoration process, and outputs mechanism prediction values; The reverse target traction layer takes the target ecological state index as input and calculates the target traction correction term for the corresponding reverse time. The temporal attention residual correction layer extracts historical observation residuals from historical repair data and combines them with the current state query vector to construct a residual correction term based on the temporal attention mechanism. The uncertainty quantification layer performs positive verification to obtain the repair process state vector, and then performs... Each Bootstrap resampling generates [a certain number of] samples. A Monte Carlo perturbation sample was obtained × For each set of prediction samples, calculate the prediction distribution information entropy and the time-varying confidence matrix of each indicator, and determine the prediction interval based on the Bootstrap sample quantiles.
[0011] Furthermore, the method for dynamic correction includes: The positive prediction deviation between the state vector of the restoration process and the target ecological state vector and the information gain of each patch are calculated. The measures are optimized with the objectives of maximizing the monitoring information gain, minimizing the positive prediction deviation and minimizing the restoration cost, so as to obtain the final restoration plan. During the final repair plan implementation, real-time monitoring data is continuously acquired and the relative deviation from the state vector of the repair process is calculated for dynamic correction. Specifically: Applying hard constraints of physical and ecological laws to the real-time ecological state vector for feasibility verification, the expression is as follows: ; in, As an indicator The theoretical maximum recovery rate is determined by the upper limit of the local potential annual productivity of natural vegetation, the geological timescale of soil development, and the physical limit of natural species dispersal. As an indicator The theoretical upper limit under local environmental conditions; Calculate the loss due to constraint violation ; When the relative deviation exceeds the threshold or the loss from the violation of constraints exceeds the preset value, it is determined that the ecological restoration trajectory deviates from the expectation or the physical constraints exceed the limit. Dynamic correction is then carried out. The shadow price of each target is calculated using the Lagrange multiplier method to identify overly aggressive targets. The corresponding components of the target ecological state vector are adjusted, and the additional measures required to break through the constraints and the additional time required to reach the target under the existing measures intensity are calculated. The target ecological state vector, intervention indicators, and restoration cycle are updated, and the measures restoration plan for the next cycle is determined.
[0012] The beneficial effects of this invention are: This invention provides a method for predicting the effects of mine ecological restoration. Compared with existing technologies, this invention has the following technical advantages: This invention introduces a reverse target traction term and establishes a reverse ecological trajectory equation. It solves the expected measure intensity and restoration path from the target state in reverse, which significantly improves the scientificity and accuracy of the initial restoration plan, achieves the unity of restoration goals and implementation paths, and avoids the impact of excessive intervention on the natural restoration process. This invention divides the restoration area into different patches and matches them with functional groups, constructs a natural invasion model, quantifies the comprehensive index of natural resilience of each patch and network-level natural invasion gain, and generates supplementary restoration schemes through target optimization. It makes full use of natural processes such as species dispersal and niche construction, significantly reduces the scale of investment in high-intensity artificial measures and long-term maintenance costs while ensuring restoration effects, and enhances the self-sustaining capacity of the restored ecosystem. This invention constructs a hybrid prediction model comprising an ecological process mechanism layer, a reverse target traction layer, a temporal attention residual correction layer, and an uncertainty quantification layer. It also embeds the soft constraints of the physical information neural network into the loss function to achieve adaptive fusion of mechanism-driven and data-driven approaches, and outputs a time-varying credibility matrix and prediction interval, thus solving the problems of model interpretability and credibility quantification. This invention calculates the monitoring information gain of each patch, constructs an objective function based on the repair cost, dynamically adjusts and generates the final repair plan, and uses real-time monitoring data to calculate the relative deviation for continuous correction. This allows the repair plan to be dynamically adjusted according to the actual recovery process, effectively avoiding over-repair or under-repair caused by static plans, maximizing the benefits of repair investment, and ensuring stable long-term repair results.

The spatially heterogeneous patches are specifically designated as P1 (bottom platform of the open-pit mine), P2 (gentle slope zone on the west edge of the mine), P3 (north slope of the spoil heap), P4 (residual area of industrial site), and P5 (tailings dam cover area). Construct patch configuration vectors, respectively , , , , Taking patch P1 as an example, the calculated edge effect ratio is 13.63. Due to the irregularity of the pit, it is corrected to 1.85. Microhabitat type Specifically, the areas of bare rock, gravelly soil, compacted platforms, and waterlogged depressions were 0.15, 0.30, 0.40, and 0.15, respectively. The calculated microhabitat heterogeneity index was 0.705. After a detailed on-site microhabitat survey and correction, the waterlogged depressions were seasonally dry, and the adjusted index was 0.62. Based on the community composition, species niche characteristics, and interspecific functional complementarity of the reference ecosystem, a functional group suitability matrix is constructed to determine the configuration of functional groups for each patch.
