Description

[0001] The invention relates to the technical field of coral reef restoration, and in particular to a method and device for selecting species of corals suitable for transplantation. Background Art

[0002] As a key component of the marine ecosystem, coral reefs are one of the most biodiverse ecosystems in the world's oceans. Coral reef ecosystems provide many important services and provide important ecological service functions to nature and human society. With the environmental damage caused by global climate change, overfishing, marine pollution, overtourism and coastal development, these factors have weakened the biodiversity in coral reefs and destroyed the ecological balance. Therefore, it is urgent to protect and restore coral reefs.

[0003] Currently, coral reef restoration is commonly carried out through coral transplantation, that is, by transplanting healthy coral fragments or coral seedlings to damaged coral reef areas, aiming to promote coral growth and increase coral coverage, ultimately restoring ecological functions and improving the stability of the ecosystem.

[0053] The embodiment of the present invention provides a method and device for selecting types of transplanted corals, which can select corals that are more suitable for repairing coral reefs during use, thereby helping to improve the effect, efficiency and success rate of coral reef restoration.

[0054] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] Please refer to Figure 1 , Figure 1 A flow chart of a method for selecting a type of coral suitable for transplantation provided by an embodiment of the present invention. The method comprises:

[0056] S110: Acquire coral information of each transplanted coral on the degraded coral reef collected at a first preset time and a second preset time of transplantation; fix a plurality of healthy coral seedlings on the attachment sites of the coral transplantation tool respectively to form various transplanted corals; the coral transplantation tool is set on the area to be repaired of 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, multiple local healthy corals that grow well in wild nurseries can be selected. For each type of local healthy coral, the local healthy coral can be cut into multiple seedlings by cutting to obtain coral seedlings corresponding to the type of healthy coral.

[0058] In practical applications, coral transplantation tools (such as coral platform repair devices) can be placed on the area to be repaired on the returned coral reef, and then each type of coral seedling can be fixed to the attachment site using cable ties. The fixed coral seedlings are transplanted corals.

[0059] In order 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 a first preset time after transplantation, and the first coral information of each transplanted coral on the degraded coral reef can be collected at a second preset time after transplantation.

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

[0061] S120: obtaining a plurality of indicator data corresponding to each transplanted coral according to the coral information of each transplanted coral;

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

[0063] S130: Screening out target coral species for transplantation based on a plurality of indicator data corresponding to each type of transplanted coral.

[0064] After determining multiple indicator data, the present application can conduct a comprehensive analysis of the multiple indicator data corresponding to each type of transplanted coral. By conducting a comprehensive analysis of the multiple indicator data of the transplanted corals, the target coral species that are more suitable for repairing the area to be repaired of the degraded coral reef can be screened out, so that the coral seedlings of the target coral species can be used to repair the area to be repaired of the degraded coral reef, thereby improving the efficiency of coral reef restoration, achieving better restoration effects, and a higher success rate of restoration.

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

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

[0067] Collecting first image information of each transplanted coral on the coral transplanting tool at a first preset time of transplantation;

[0068] The second image information and the coral sample of each transplanted coral on the coral transplanting tool at a second preset time after the transplantation are collected.

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

[0070] In practical applications, a ruler with scales can be used as a reference at both the first preset time and the second preset time to collect images of various transplanted corals on the coral transplantation tool. Specifically, a camera can be used to vertically project and shoot the coral fragments of various transplanted corals, so as to obtain first image information and second image information corresponding to each transplanted coral. In addition, a small amount of coral samples can be collected for each transplanted coral at the second preset time of coral transplantation, and the coral samples of each transplanted coral can be stored separately, for example, separately in marked self-sealing plastic bags to prevent cross contamination between samples. The collected coral samples can be frozen for storage, so that the corresponding indicator data can be obtained through subsequent analysis of the coral samples.

[0071] In one embodiment, the plurality of indicator data includes at least two of survival rate, growth increase ratio, health status index and environmental tolerance.

[0072] It can be understood that since the survival rate, growth increase ratio, health status index and environmental tolerance are easy to obtain and can accurately reflect the ability of transplanted corals to adapt to the environment, growth potential, physiological health and adaptation range, therefore, in the embodiment of the present invention, a comprehensive analysis of each transplanted coral can be performed based on the survival rate, growth increase ratio, health status index and environmental tolerance, which is conducive to determining the type of coral that is more suitable for transplantation.

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

[0074] For each transplanted coral, the survival rate and growth ratio of the transplanted coral are obtained according to the first image information and the second image information corresponding to the transplanted coral;

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

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

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

[0078] It should be noted that the multiple indicator data in this application may include survival rate, growth increase ratio, health status index and environmental tolerance, and the health status index is reflected by the zooxanthellae density per unit coral surface area, and the value of the zooxanthellae density per unit coral surface area is used as the indicator value of the health status index. In this application, the environmental tolerance is reflected by the tissue biomass per unit coral surface area, and the value of the tissue biomass per unit coral surface area is used as the indicator value of the environmental tolerance.

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

[0080] It is understandable that, for each type of transplanted coral, in the embodiment of the present invention, the survival rate and growth ratio of the transplanted coral can be obtained according to the first image information and the second image information corresponding to the transplanted coral, which can be specifically achieved through the following process:

[0081] According to the first image information and the second image information of the transplanted corals, the number of surviving corals, the total number of transplants, the initial coral area and the final coral area are obtained;

[0082] Determine the survival rate of transplanted corals based on the number of surviving corals and the total number of transplants;

[0083] Determine the growth rate of transplanted corals 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 transplanted coral can be collected immediately after the transplantation is completed. For each transplanted coral, the number and projection area of ​​the corresponding surviving tissue part can be obtained by performing image recognition analysis on the first image information (for example, the first image information can be recognized and analyzed by ImageJ software), that is, the total number of transplants and the initial coral area of ​​the transplanted coral at the first preset time are determined. The second image information of each transplanted coral is collected at a second preset time after a period of time. For each transplanted coral, the number of stored tissue parts and the corresponding projection area can be obtained by performing recognition analysis on the second image information (for example, the second image information can be recognized and analyzed by ImageJ software), that is, the number of stored corals and the final coral area of ​​the transplanted coral at the second preset time are obtained.

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

[0086] In the process of determining the zooxanthella density and tissue biomass per unit coral surface area, the collected coral samples can be frozen and preserved in advance, and the frozen and preserved coral samples can be analyzed to obtain easily measurable physiological index data such as the zooxanthella density per unit coral surface area and the tissue biomass per unit coral surface area. Specifically, filtered seawater and a toothbrush can be used to rinse the surface of the coral sample in the laboratory, 10 mL of the rinsed solution can be measured, and the zooxanthella density can be determined by repeated counting under a microscope using a hemocytometer. The coral sample is dried in an oven at 50°C to constant weight and then burned in a muffle furnace at 450°C for more than 4 hours. The difference between the dry weight and the ashing weight is the tissue biomass. Zooxanthellae and corals are symbiotic in nutrition, and their density can directly characterize the health status of the coral; tissue biomass reflects the energy storage capacity of the coral, and the higher the value, the stronger the tolerance of the coral in an adverse environment. Therefore, in the embodiment of the present invention, the value of the zooxanthella density per unit coral surface area is directly used as the index value of the health status index, and the value of the tissue biomass per unit coral surface area is used as the index value of the environmental tolerance.

[0087] It should also be noted that in order to improve the accuracy of the comprehensive evaluation of transplanted corals based on multiple indicator data of transplanted corals, the indicator values ​​of each indicator data obtained for each type of transplanted coral can be dimensionally processed, such as minimum-maximum normalization processing, and the data can be scaled to the [0,1] interval to eliminate the influence of the indicator dimension and obtain a multi-dimensional standard data set of evaluation indicators.

[0088] In one embodiment, the target coral species for transplantation are screened out based on multiple indicator data corresponding to each transplanted coral, including:

[0089] According to the environmental requirements of different to-be-restored areas of different degraded coral reefs, weights corresponding to various indicator data corresponding to the environmental requirements of the to-be-restored areas of the degraded coral reefs are determined in advance;

[0090] For each transplanted coral, the comprehensive score of the transplanted coral is obtained according to the values ​​of each indicator data of the transplanted coral and the weight corresponding to each indicator data;

[0091] Based on the comprehensive score of each transplanted coral, the target coral species for transplantation were screened.

[0092] It should be noted that in the embodiment of the present invention, the weights corresponding to the various indicator data corresponding to the environmental requirements of the area to be restored of the degraded coral reef can be determined in advance according to the environmental requirements of the area to be restored of the degraded coral reef. Specifically, the expert scoring method can be used to determine the weights corresponding to each indicator data according to the environmental requirements of the current area to be restored of 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 index data of the transplanted coral, the comprehensive score of the transplanted coral can be obtained according to the weight corresponding to each index data and the index value of each index data, thereby obtaining the comprehensive score of each type of transplanted coral, and according to each comprehensive score, the target coral species ultimately used for transplantation can be screened out.

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

[0095] For example, according to the environmental requirements of the area to be restored for the degraded coral reef, it is determined that coral species that can quickly cover the area and have strong adaptability to the environment need to be screened out. The weights of the various indicator data determined by the expert scoring method are: survival rate 30%, growth increase ratio 30%, health status index 20%, and environmental tolerance 20%. Then, for each type of transplanted coral, the comprehensive score of the transplanted coral = survival rate × 30% + growth increase ratio × 30% + zooxanthellae density per unit coral surface area × 20% + tissue biomass per unit coral surface area × 20%, so that the comprehensive score of each type of transplanted coral can be obtained.

[0096] In one embodiment, the process of screening out the target coral species for transplantation according to the comprehensive score of each transplanted coral in S140 may include:

[0097] Sort each transplanted coral according to the size of the comprehensive score;

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

[0099] It should be noted that, in the embodiment of the present invention, a preset number (one or more) of coral species with the highest comprehensive scores can be selected from multiple types of transplanted corals as target coral species, or multiple coral species with comprehensive scores greater than the preset scores can be selected as target coral species, so as to better screen out coral species that are more suitable for repairing the area to be repaired of the degraded coral reef, so that the corals of these target coral species can be used to repair the area to be repaired of the degraded coral reef in the future, so as to better ensure the efficiency and success rate of coral restoration. In the embodiment of the present invention, multiple indicator data of transplanted corals are combined with corresponding weights to comprehensively evaluate each transplanted coral, which can more comprehensively and reliably evaluate the adaptability of different coral species, which is conducive to improving the success rate of artificial coral transplantation and promoting coral reef recovery.

[0100] It can be seen that in the present application, a coral transplantation tool is set in advance on the area to be repaired of the degraded coral reef, and multiple types of healthy coral seedlings are fixed on the attachment point of the coral transplantation tool, so that multiple types of coral seedlings are transplanted on the area to be repaired of the degraded coral reef to form multiple transplanted corals, and the coral information of each transplanted coral is collected at the first preset time and the second preset time after the transplantation, and then multiple indicator data of each transplanted coral are obtained according to the coral information of each transplanted coral collected at these two times, and further according to the multiple indicator data of each transplanted coral, the target coral species corresponding to the corals finally used for transplantation to the area to be repaired of the degraded coral reef is screened; in the present application, a comprehensive evaluation is carried out from multiple indicator data for each transplanted coral, so as to determine the final target coral species, so that the determined target coral species finally used for transplantation is more suitable for transplantation in the area to be repaired of the degraded coral reef, which is conducive to improving the efficiency and effect of coral reef restoration and having a higher success rate.

[0101] The method provided by the embodiment of the present invention is more suitable for large-scale coral ecological restoration projects. Users can screen the types of corals suitable for transplantation in a specific area, which not only provides a quantitative decision-making tool for coral restoration work, but also improves the overall efficiency of coral restoration and saves 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 effect of ecological restoration.

[0102] For example, taking the degraded coral area in the north of Wuzhizhou Island in Hainan as an example, 30 coral assembly restoration devices can be placed in the degraded coral reefs to transplant 10 healthy coral seedlings, including 8 branching corals, 1 leaf coral and 1 shell coral. The first image information and the second image information of each transplanted coral are collected on the first day and 360 days after the coral seedlings are transplanted. Figure 3As shown in the figure, and on the 360th day, coral samples of each type of transplanted coral are collected, and the survival rate, growth increase ratio, zooxanthellae density per unit coral surface area, and tissue biomass of the transplanted corals are obtained by analyzing the first image information, the second image information, and the coral samples.

[0103] The original data of these four indicators were subjected to one-way ANOVA and the letter notation method was used to display the multiple comparison results, such as Figure 4 As shown, it can be seen that at 369 days after transplantation, the survival rates of Acropora hyacinthus and Montipora digitata were the lowest, while the survival rates of Porites slender and adjacent sand corals remained at 100%; the area increase ratio of Strychophys scleractinia reached the highest, while that of Acropora hornba and Strychophys jewel were the lowest; the density of zooxanthellae in Porites slender and adjacent sand corals was higher, while that in Strychophys scleractinia was lower. The highest coral tissue biomass was in Porites slender, and the lowest was in Strychophys scleractinia. The analysis results show that there are differences in the results of evaluation of different indicators, and it is difficult to screen out reliable species.

[0104] In order to screen out controllable species, the original data of these indicator data can be subjected to minimum-maximum normalization processing, and the original data can be scaled to the interval [0, 1] to eliminate the influence of dimension, thereby establishing a multidimensional data set of evaluation indicators. In the embodiment of the present invention, taking into account the restoration environment and actual needs of Wuzhizhou Island, in order to screen out species that can quickly cover the degraded area and have strong adaptability to the environment, the weights of each indicator data can be determined as 30% for survival rate, 30% for growth rate, 20% for health status, and 20% for environmental tolerance. Then, according to the indicator values ​​of each indicator data after normalization and the corresponding weights, the comprehensive score of each transplanted coral can be obtained, and then the target coral species can be determined based on the comprehensive scores of various transplanted corals. Figure 5 As shown, it can be seen that the slender column coral and the small leaf staghorn coral have the highest comprehensive scores and are most suitable for transplantation in this area.

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