Description

Technical Field

[0001] This invention relates to the field of coral reef restoration technology, and in particular to a method and apparatus for selecting suitable coral species for transplantation. Background Technology

[0002] Coral reefs, as a key component of marine ecosystems, are among the most biodiverse ecosystems in the world's oceans. Coral reef ecosystems provide numerous vital services, offering crucial ecological benefits to both nature and human society. However, global climate change, overfishing, marine pollution, excessive tourism, and environmental damage caused by coastal development have collectively weakened the biodiversity of coral reefs and disrupted their ecological balance. Therefore, the protection and restoration of coral reefs are urgently needed.

[0003] Currently, coral reef restoration is typically achieved through coral transplantation, which involves transplanting healthy coral fragments or seedlings to damaged reef areas. The aim is to promote coral growth and increase coral coverage, ultimately restoring ecological functions and improving ecosystem stability.

[0004] Coral transplantation can accelerate the recovery process of coral reefs, but it requires a large number of transplantable coral seedlings. However, different coral species exhibit variations in various indicators under the same transplantation conditions. Current techniques often consider only a single indicator when selecting transplantable coral species, leading to poor restoration effects and low restoration efficiency.

[0005] Therefore, how to select the coral species used for transplantation to improve the effect and success rate of coral reef restoration has become a technical problem to be solved in this field. Summary of the Invention

[0006] The purpose of this invention is to provide a method and apparatus for selecting suitable coral species for transplantation, which can select corals that are more suitable for coral reef restoration during use, thereby improving the restoration effect, efficiency and success rate of coral reef restoration.

[0007] To address the aforementioned technical problems, the embodiments of the present invention provide the following technical solutions:

[0008] This invention provides a method for selecting suitable coral species for transplantation, comprising:

[0009] Multiple healthy coral seedlings are fixed to the attachment sites of a coral transplantation tool to form various transplanted corals; the coral transplantation tool is placed on the area of ​​the degraded coral reef to be restored.

[0010] The method involves acquiring coral information for each type of transplanted coral on a degraded coral reef, collected at a first preset time and a second preset time, respectively; wherein multiple healthy coral seedlings are pre-fixed onto the attachment sites of the coral transplantation tool to form various corresponding transplanted corals; the coral transplantation tool is set on the area to be repaired on the degraded coral reef, and the first preset time is shorter than the second preset time.

[0011] Based on the coral information of each transplanted coral, multiple indicator data corresponding to each transplanted coral are obtained;

[0012] Based on multiple index data corresponding to each of the transplanted corals, the target coral species for final transplantation are selected.

[0013] In one embodiment, acquiring coral information for each transplanted coral on a degraded coral reef, collected at a first preset time and a second preset time respectively, includes:

[0014] First image information of each type of transplanted coral was acquired on the coral transplantation tool at the first preset time of transplantation;

[0015] Second image information and coral samples of each transplanted coral were collected on the coral transplantation tool at a second preset time after transplantation.

[0016] In one implementation, the multiple data indicators include at least two of the following: survival rate, growth ratio, health status indicators, and environmental tolerance.

[0017] In one embodiment, obtaining multiple indicator data corresponding to each transplanted coral based on its coral information includes:

[0018] For each type of transplanted coral, the survival rate and growth ratio of the transplanted coral are obtained based on the first image information and the second image information corresponding to the transplanted coral.

[0019] Based on the coral samples of the transplanted corals, determine the zooxanthellae density and tissue biomass per unit coral surface area.

[0020] The density of zooxanthellae per unit coral surface area corresponding to the transplanted coral is used as the indicator value of health status.

[0021] The tissue biomass corresponding to the transplanted coral is used as an indicator of the environmental tolerance of the transplanted coral.

[0022] In one embodiment, obtaining the survival rate and growth ratio of the transplanted coral based on the first image information and the second image information corresponding to the transplanted coral includes:

[0023] Based on the first and second image information of the transplanted corals, the number of surviving corals, the total number of transplanted corals, the initial coral area, and the final coral area are obtained.

[0024] The survival rate of the transplanted corals is determined based on the number of surviving corals and the total number of transplanted corals.

[0025] The growth rate of the transplanted coral is determined based on the final coral area and the initial coral area.

[0026] In one implementation, the step of selecting the target coral species for transplantation based on multiple indicator data corresponding to each of the transplanted corals includes:

[0027] In advance, based on the environmental requirements of different areas to be restored in different degraded coral reefs, the weights corresponding to each indicator data corresponding to the environmental requirements of the areas to be restored in the degraded coral reefs are determined respectively.

[0028] For each type of transplanted coral, a comprehensive score is obtained based on the values ​​of each indicator data of the transplanted coral and the weight corresponding to each indicator data.

[0029] Based on the comprehensive score of each transplanted coral, the target coral species for final transplantation are selected.

[0030] In one embodiment, obtaining a comprehensive score for the transplanted coral based on the values ​​of various indicator data and the weight corresponding to each indicator data includes:

[0031] For each indicator data of the transplanted coral, the value of the indicator data is multiplied by the corresponding weight to obtain the product corresponding to the indicator data;

[0032] The comprehensive score of the transplanted coral is obtained by summing the products of each of the aforementioned indicator data.

[0033] In one implementation, the step of selecting the target coral species for final transplantation based on the comprehensive score of each of the transplanted corals includes:

[0034] Each type of transplanted coral was sorted according to its overall score;

[0035] The transplanted corals with a comprehensive score greater than the preset score are selected as the final target coral species for transplantation, or the species corresponding to the preset number of transplanted corals with the highest comprehensive scores are selected as the final target coral species for transplantation.

[0036] In one implementation, the step of pre-determining the weights of various indicator data corresponding to the environmental needs of different areas to be restored in different degraded coral reefs includes:

[0037] In advance, an expert scoring method is used to determine the weights of each indicator data corresponding to the environmental needs of different areas to be restored in different degraded coral reefs.

[0038] Another aspect of the present invention provides a selection device adapted to transplanted coral species, comprising:

[0039] A collection module is used to acquire coral information of each type of transplanted coral on a degraded coral reef collected at a first preset time and a second preset time, respectively; multiple healthy coral seedlings are pre-fixed on the attachment sites of the coral transplantation tool to form various transplanted corals; the coral transplantation tool is set on the area to be repaired on the degraded coral reef, and the first preset time is shorter than the second preset time.

[0040] An analysis module is used to obtain multiple indicator data corresponding to each type of transplanted coral based on the coral information of each type of transplanted coral.

[0041] A screening module is used to select the target coral species for final transplantation based on multiple indicator data corresponding to each of the transplanted corals.

[0042] As can be seen from the above technical solutions, the embodiments of the present invention have the following advantages:

[0043] This invention provides a method for selecting suitable coral species for transplantation, comprising: acquiring coral information of each type of transplantable coral collected from degraded coral reefs at a first preset time and a second preset time; pre-fixing multiple healthy coral seedlings onto attachment sites of a coral transplantation tool to form various transplantable corals; setting the coral transplantation tool on the area to be repaired on the degraded coral reef, with the first preset time being less than the second preset time; obtaining multiple indicator data corresponding to each type of transplantable coral based on the coral information; and selecting the target coral species for final transplantation based on the multiple indicator data corresponding to each type of transplantable coral.

[0044] Therefore, this application demonstrates that by pre-setting coral transplantation tools on the area to be restored of the degraded coral reef, multiple species of healthy coral seedlings are fixed to the attachment points of the tools, thereby transplanting multiple species of coral seedlings into the area to be restored, forming various transplanted corals. Coral information for each transplanted coral is collected at a first and second pre-set time after transplantation. Based on this information, multiple indicator data for each transplanted coral are obtained. Furthermore, based on these multiple indicator data, the target coral species corresponding to the final coral to be transplanted to the area to be restored on the degraded coral reef are selected. This application comprehensively evaluates each transplanted coral based on multiple indicator data to determine the final target coral species, ensuring that the determined target coral species are more suitable for transplantation into the area to be restored on the degraded coral reef, thus improving the efficiency and effectiveness of coral reef restoration and increasing the success rate.

[0045] Furthermore, the present invention also provides a corresponding implementation device for the selection method of transplanted coral species, which further makes the method more practical, and the device has corresponding advantages. Attached Figure Description

[0053] This invention provides a method and apparatus for selecting suitable coral species for transplantation. During use, it can select corals that are more suitable for coral reef restoration, which helps to improve the restoration effect, efficiency and success rate of coral reef restoration.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating a method for selecting suitable coral species for transplantation, provided by an embodiment of the present invention. The method includes:

[0056] S110: Obtain coral information for each type of transplanted coral on the degraded coral reef collected at the first and second preset times respectively; fix multiple healthy coral seedlings onto the attachment sites of the coral transplantation tool to form various transplanted corals; the coral transplantation tool is set on the area to be repaired on the degraded coral reef, and the first preset time is less than the second preset time.

[0057] It should be noted that multiple types of healthy coral seedlings can be selected in advance. For example, select various local healthy corals that are growing well in the wild nursery. For each type of local healthy coral, the local healthy coral can be cut into multiple seedlings by cutting, so as to obtain coral seedlings corresponding to that type of healthy coral.

[0058] In practical applications, coral transplantation tools (such as coral patchwork restoration devices) can be placed on the area to be restored on the returned coral reef, and then cable ties can be used to fix each type of coral seedling to the attachment site. The fixed coral seedling is the transplanted coral.

[0059] To accurately obtain the growth status of each transplanted coral, the first coral information of each transplanted coral on the degraded coral reef can be collected at the first preset time after transplantation, and the first coral information of each transplanted coral on the degraded coral reef can be collected at the second preset time after transplantation.

[0060] For example, first coral information for each transplanted coral on the degraded reef can be collected on the first day after transplantation or immediately after transplantation, and second coral information for each transplanted coral on the degraded reef can be collected on the 360th day after transplantation.

[0061] S120: Based on the coral information of each transplanted coral, obtain multiple indicator data corresponding to each transplanted coral;

[0062] In this embodiment of the invention, multiple indicator data for each type of transplanted coral can be determined based on the first coral information and the second coral information collected in two time periods, that is, multiple indicator data corresponding to each type of transplanted coral can be determined.

[0063] S130: Based on multiple indicator data corresponding to each type of transplanted coral, the target coral species for final transplantation are selected.

[0064] After identifying multiple indicator data, this application can comprehensively analyze the multiple indicator data corresponding to each type of transplanted coral. By comprehensively analyzing the multiple indicator data of the transplanted coral, it is possible to screen out target coral species that are more suitable for the restoration of degraded coral reef areas. This allows for the subsequent use of coral seedlings of the target coral species to restore the degraded coral reef areas, thereby improving the efficiency of coral reef restoration, achieving better restoration results, and increasing the success rate of restoration.

[0065] Compared to the previous embodiment, this embodiment further explains and optimizes the technical solution. Specifically:

[0066] In one embodiment, the process of obtaining coral information for each transplanted coral on the degraded coral reef collected at a first preset time and a second preset time during transplantation in S110 may include:

[0067] First image information of each type of transplanted coral was collected using a coral transplantation tool at the first preset time of transplantation.

[0068] Second image information and coral samples of each transplanted coral were collected on the coral transplantation tool at the second preset time after transplantation.

[0069] It should be noted that, in order to accurately determine the growth status of the transplanted corals, in this embodiment of the application, the first image information of each type of transplanted coral on the coral transplantation tool can be collected at a first preset time after the transplantation of multiple healthy coral seedlings, and the second image information and coral sample of each type of transplanted coral on the coral transplantation tool can be collected at a second preset time after the transplantation is completed. The number and growth status of the transplanted corals can be accurately identified through the first and second image information, and the coral sample of each type of transplanted coral collected at the second preset time can further determine the physiological indicators of the transplanted corals after the period from the first preset time to the second preset time, so as to accurately determine the corresponding indicator data.

[0070] In practical applications, images of various transplanted corals on the coral transplantation tool can be captured using a graduated ruler as a reference at both the first and second preset times. Specifically, a camera can be used to vertically project images of coral fragments from each type of transplanted coral, thereby obtaining first and second image information corresponding to each type of transplanted coral. Additionally, at the second preset time of coral transplantation, a small number of coral samples can be collected for each type of transplanted coral. These samples are stored separately, for example, in labeled self-sealing plastic bags, to prevent cross-contamination. The collected coral samples can be frozen for later analysis to obtain corresponding indicator data.

[0071] In one implementation, the multiple data indicators include at least two of the following: survival rate, growth ratio, health status indicators, and environmental tolerance.

[0072] It is understandable that, since data on survival rate, growth ratio, health status indicators, and environmental tolerance are readily available and can accurately reflect the transplanted coral's ability to adapt to the environment, its growth potential, physiological health, and range of adaptation, this embodiment of the invention can comprehensively analyze each transplanted coral based on these data, thereby helping to determine the coral species more suitable for transplantation.

[0073] In one embodiment, the process of obtaining multiple indicator data corresponding to each transplanted coral based on the coral information of each transplanted coral in S120 may include:

[0074] For each type of transplanted coral, the survival rate and growth ratio of the transplanted coral are obtained based on the first and second image information corresponding to the transplanted coral.

[0075] Based on the coral samples of transplanted corals, determine the zooxanthellae density and tissue biomass per unit coral surface area.

[0076] The density of zooxanthellae per unit coral surface area corresponding to the transplanted coral is used as the indicator value of health status.

[0077] The tissue biomass corresponding to the transplanted coral was used as an indicator of the environmental tolerance of the transplanted coral.

[0078] It should be noted that the various indicators in this application may include survival rate, growth ratio, health status indicators, and environmental tolerance. Furthermore, the density of zooxanthellae per unit coral surface area is used to reflect the health status indicator, and this value is taken as the indicator value. In this application, the tissue biomass per unit coral surface area is used to reflect environmental tolerance, and this value is taken as the indicator value for environmental tolerance.

[0079] Specifically, the survival rate and growth rate of the transplanted coral can be obtained based on the first and second image information corresponding to the transplanted coral.

[0080] It is understood that, for each type of transplanted coral, the survival rate and growth ratio of the transplanted coral can be obtained based on the first image information and the second image information corresponding to the transplanted coral in this embodiment of the invention. Specifically, this can be achieved through the following process:

[0081] Based on the first and second image information of the transplanted corals, the number of surviving corals, the total number of transplanted corals, the initial coral area, and the final coral area are obtained.

[0082] The survival rate of the transplanted corals is determined based on the number of surviving corals and the total number of transplanted corals.

[0083] The growth rate of transplanted corals is determined based on the final coral area and the initial coral area.

[0084] It should be noted that in practical applications, the first image information of each type of transplanted coral can be acquired immediately after transplantation. For each type of transplanted coral, image recognition analysis (e.g., using ImageJ software) can be performed on the first image information to obtain the number and projected area of ​​the corresponding surviving tissue parts, that is, to determine the total number of transplanted corals and the initial coral area at the first preset time. After a certain period of time, the second image information of each type of transplanted coral is acquired at the second preset time. For each type of transplanted coral, the number of stored tissue parts and the corresponding projected area can be obtained by performing recognition analysis on the second image information (e.g., using ImageJ software), that is, to obtain the number of stored corals and the final coral area at the second preset time.

[0085] Specifically, the survival rate of transplanted corals = (number of surviving corals / total number of transplanted corals) * 100%; the growth rate of transplanted corals = [(final coral area - initial coral area) / initial coral area] * 100%.

[0086] In determining the zooxanthellae density and tissue biomass per unit coral surface area, the collected coral samples can be cryopreserved beforehand. Analysis of the cryopreserved samples yields easily measurable physiological indicators such as zooxanthellae density and tissue biomass per unit coral surface area. Specifically, in the laboratory, filtered seawater and a dental irrigator can be used to rinse the coral sample surface. 10 mL of the rinse solution is measured, and the zooxanthellae density is determined by repeated counting under a microscope using a hemocytometer. The coral sample is then dried to constant weight in a 50°C oven and calcined in a muffle furnace at 450°C for at least 4 hours. The difference between the dry weight and the ashing weight is the tissue biomass. Zooxanthellae and corals have a symbiotic relationship, and their density directly characterizes the coral's health status. Tissue biomass reflects the coral's energy storage capacity; higher values ​​indicate stronger tolerance to adverse environments. Therefore, in this embodiment of the invention, the zooxanthellae density per unit coral surface area is directly used as an indicator of health status, and the tissue biomass per unit coral surface area is used as an indicator of environmental tolerance.

[0087] It should also be noted that, in order to improve the accuracy of comprehensive evaluation of transplanted corals based on multiple indicator data, the indicator values ​​of each indicator data obtained for each type of transplanted coral can be dimensionless, for example, by mini-maximum normalization. The data can be scaled proportionally to the [0,1] interval to eliminate the influence of indicator dimensions and obtain a multi-dimensional standard dataset of evaluation indicators.

[0088] In one implementation, the target coral species for final transplantation are selected based on multiple indicator data corresponding to each type of transplanted coral, including:

[0089] In advance, based on the environmental needs of different areas to be restored in different degraded coral reefs, determine the weights of each indicator data corresponding to the environmental needs of the areas to be restored in different degraded coral reefs;

[0090] For each type of transplanted coral, a comprehensive score is obtained based on the values ​​of various indicators of the transplanted coral and the weight of each indicator.

[0091] Based on the comprehensive score of each transplanted coral, the target coral species for final transplantation are selected.

[0092] It should be noted that, in this embodiment of the invention, the weights of each indicator data corresponding to the environmental needs of different areas to be restored in different degraded coral reefs can be determined in advance. Specifically, an expert scoring method can be used to determine the weight of each indicator data according to the environmental needs of the current area to be restored in the current degraded coral reef. For example, survival rate a%, growth rate b%, health status index c%, environmental tolerance d%, and a% + b% + c% + d% = 100%.

[0093] For each type of transplanted coral, after obtaining the index value of each indicator data of the transplanted coral, we can further obtain the comprehensive score of the transplanted coral by combining the weight corresponding to each indicator data with the index value of each indicator data. Thus, we obtain the comprehensive score of each type of transplanted coral, and select the target coral species for final transplantation based on the comprehensive scores.

[0094] Specifically, for each indicator data of transplanted coral, the value of the indicator data can be multiplied by its corresponding weight to obtain the product corresponding to the indicator data; then the products corresponding to each indicator data are added together to obtain the comprehensive score of the transplanted coral.

[0095] For example, based on the environmental needs of the area to be restored in this degraded coral reef, it is determined that coral species that can quickly cover the area and are highly adaptable to the environment need to be selected. The weights of each indicator data determined by the expert scoring method are as follows: survival rate 30%, growth rate 30%, health status index 20%, and environmental tolerance 20%. Therefore, for each transplanted coral, the comprehensive score is calculated as follows: survival rate × 30% + growth rate × 30% + zooxanthellae density per unit coral surface area × 20% + tissue biomass per unit coral surface area × 20%.

[0096] In one implementation, the process of selecting the target coral species for transplantation based on the comprehensive score of each transplanted coral in S140 may include:

[0097] Each type of transplanted coral was sorted according to its overall score;

[0098] The transplanted corals with a comprehensive score greater than the preset score are selected as the final target coral species for transplantation, or the species corresponding to the preset number of transplanted corals with the highest comprehensive scores are selected as the final target coral species for transplantation.

[0099] It should be noted that, in this embodiment of the invention, a predetermined number (one or more) of coral species with the highest comprehensive scores can be selected as target coral species from multiple transplanted coral species, or multiple coral species with comprehensive scores greater than the predetermined scores can be selected as target coral species. This allows for better screening of coral species more suitable for restoring degraded coral reef areas, so that these target coral species can be used to restore the degraded coral reef areas, thereby better ensuring coral restoration efficiency and success rate. In this embodiment of the invention, multiple indicator data of transplanted corals are combined with corresponding weights to comprehensively evaluate each type of transplanted coral, which can more comprehensively and reliably assess the adaptability of different coral species, thus improving the success rate of artificial coral transplantation and promoting coral reef recovery.

[0100] Therefore, this application demonstrates that by pre-setting a coral transplantation tool on the area to be restored of the degraded coral reef, multiple healthy coral seedlings of various species are fixed to the attachment points of the tool, thus transplanting multiple species of coral seedlings into the area to be restored, forming various transplanted corals. Coral information for each transplanted coral is collected at a first and second pre-set time after transplantation. Based on this information, multiple indicator data for each transplanted coral are obtained. Furthermore, based on these multiple indicator data, the target coral species corresponding to the final coral to be transplanted to the area to be restored on the degraded coral reef are selected. This application comprehensively evaluates each transplanted coral based on multiple indicator data to determine the final target coral species, ensuring that the determined target coral species are more suitable for transplantation into the area to be restored on the degraded coral reef, thereby improving the efficiency and effectiveness of coral reef restoration and increasing the success rate.

[0101] The method provided in this invention is more suitable for large-scale coral reef restoration projects. Users can select coral species suitable for transplantation in specific areas, providing a quantitative decision-making tool for coral restoration work and improving overall efficiency while saving resources and time. It can better optimize the selection of the most effective restoration species in coral restoration projects, thereby improving the success rate of coral transplantation and the effectiveness of ecological restoration.

[0102] For example, taking the degraded coral area in the northern part of Wuzhizhou Island, Hainan Province as an example, 30 coral reef restoration devices can be deployed on the degraded coral reef, and 10 healthy coral seedlings can be transplanted, including 8 species of branching corals, 1 species of leaf-like coral, and 1 species of shell-like coral. First and second image information (e.g., [images of the transplanted corals]) of each transplanted coral species can be collected on the first day and 360th day, respectively. Figure 3As shown in the image), coral samples of each transplanted coral were collected on day 360. By analyzing the first image information, the second image information, and the coral samples, the survival rate, growth ratio, zooxanthellae density per unit coral surface area, and tissue biomass of the transplanted corals were obtained.

[0103] The results of multiple comparisons are presented by performing one-way ANOVA and letter notation on the raw data of these four indicators, such as... Figure 4 As shown, at 369 days after transplantation, *Hyacinthus hyacinthus* and *Rhododendron digitatum* had the lowest survival rates, while *Symplocos septemlobus* and *Sarcandra glabra* maintained a 100% survival rate. *Symplocos septemlobus* showed the highest area increase, while *Symplocos septemlobus* and *Symplocos jewelosa* had the lowest. *Symplocos septemlobus* and *Sarcandra glabra* had higher zooxanthellae densities, while *Symplocos septemlobus* had lower densities. *Symplocos septemlobus* had the highest coral tissue biomass, while *Symplocos septemlobus* had the lowest. This analysis indicates that the results of different indicator assessments vary, making it difficult to screen reliable species.

[0104] To screen for controllable species, the raw data of these indicators can be subjected to min-max normalization, scaling the raw data proportionally to the [0, 1] interval to eliminate the influence of dimensions, thereby establishing a multidimensional dataset of evaluation indicators. In this embodiment of the invention, considering the restoration environment and actual needs of Wuzhizhou, to screen for species that can quickly cover degraded areas and are highly adaptable to the environment, the weights of each indicator data can be determined as follows: survival rate 30%, growth ratio 30%, health status 20%, and environmental tolerance 20%. Based on the index values ​​of each indicator data after normalization, combined with the corresponding weights, a comprehensive score for each transplanted coral can be obtained. Then, based on the comprehensive scores of various transplanted corals, the target coral species can be determined. Figure 5 As shown, *Coralia serratifolia* and *Coralia pulcherrima* have the highest overall scores and are the most suitable for transplantation in this area.

[0105] in, Figure 4 and Figure 5 The letter-based method (abcd) mentioned in the text is a method in mathematical statistics that visually displays the results of multiple comparisons. It assigns a letter to each group to indicate significant differences between groups. The same letter indicates no significant difference between groups, while different letters indicate significant differences between groups.
