Description

Technical Field

[0001] The present invention relates to the technical field of marine resource management planning, and in particular to a method for determining the vertical compatibility of multi-dimensional sea area activities. Background Art

[0002] With the rapid development of the marine economy and the increasing intensity of marine resource development, high-quality marine space resources are becoming increasingly scarce, becoming a bottleneck restricting the sustainable development of the ocean. The traditional planar management model has become difficult to solve new problems such as cross-use and overlapping use of the sea. Under this demand, the three-dimensional layered utilization model of the sea area has become an effective way to optimize the allocation of marine resources and improve the efficiency of space utilization.

[0003] In the existing technology, the vertical compatibility judgment of sea-use activities in sea areas mostly adopts a static judgment process, which is difficult to dynamically reflect the changes in spatial use of sea-use activities under different time periods and conditions. The lack of effective models and data support leads to increased subjectivity and uncertainty in the judgment results. Therefore, how to analyze the spatial use characteristics of sea-use activities from the three perspectives of spatial dependence, functional components and time continuity, and form a set of judgment processes for compatible combinations of sea-use activities to improve the accuracy and objectivity of compatibility judgment is the problem to be solved by the present invention. To this end, a multi-dimensional sea-use activity vertical compatibility combination judgment method is proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a multi-dimensional method for determining the vertical compatibility of sea activities in a sea area, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: A multi-dimensional sea area activity vertical compatibility combination determination method includes the following steps: S1. Based on the sea area use activity database, determine the types of sea use activities involved in the identification, analyze the spatial dependence of each activity on the sea area's water surface, water body, seabed, and subsoil, construct a sea use activity spatial dependence matrix, and identify the main occupied space and the additional occupied space; S2. Classify the functional components of each type of sea-use activity, analyze the rigidity and flexibility of its space occupation, and determine the strength of exclusivity; S3. Analyze the spatial occupation time characteristics of various sea-use activities during the operation period and the construction and maintenance period, identify temporal continuity and intermittency, and determine temporal flexibility; S4. Based on spatial dependency analysis, eliminate combinations of sea-use activities with major spatial overlap, construct a preliminary discriminant matrix of vertical compatibility, narrow the discrimination scope, and preliminarily screen compatible combinations; S5. Combining the spatial dependency matrix, functional component exclusivity, and temporal flexibility, simulate spatial conflicts under different combinations; S6. Integrate the multi-dimensional analysis results, combine them with the sea use safety factors to verify and adjust the compatibility judgment results, and output the final multi-dimensional vertical compatibility combination of sea area activities.

[0006] A further improvement of the technical solution of the present invention is that: S1 includes: Based on the database of sea area use activities, sort out and screen the types of sea use activities that need to be identified, and clarify their development and utilization characteristics and sea area space requirements; For each type of sea-use activity, analyze its vertical spatial dependence on the sea surface, water body, seabed, and subsoil, and divide the space into primary occupied space (long-term high dependence) and secondary occupied space (intermittent low dependence), forming a detailed description of the spatial dependence relationship; Based on the analysis results, a spatial dependency matrix of sea-use activities is constructed. Combined with the functional characteristics of sea-use activities and the spatial occupation range, the main occupied space and additional occupied space are clarified, providing a spatial stratification basis for vertical compatibility judgment.

[0007] A further improvement of the technical solution of the present invention is that: S2 includes: Disassemble functional components by type of sea-use activity, including personnel, mobile equipment, vessels, facilities, and structures, clarify the functional positioning and spatial distribution characteristics of each functional component, and by analyzing the correlation between functional components, define their occupation range on the water surface, water body, seabed, and subsoil to form a spatial occupation baseline; Based on the spatial requirements of functional components, differentiate between rigid (fixed location, non-adjustable) and flexible (movable, shareable) attributes. Combined with the functional components' exclusive demands for marine resources, assess their exclusivity strength and determine the level of exclusivity, categorizing it into high, medium, and low, to identify potential risks of spatial conflicts. Summarize the attribute classification and exclusivity strength of each functional component to form a map of sea activity space occupancy attributes. Based on the map, analyze the compatibility of different activities in the vertical space and clarify the spatial hierarchy that can be shared or needs to be isolated.

[0008] A further improvement of the technical solution of the present invention is that the process of determining the exclusive strength level is: Classify the attributes of the functional components of various sea-use activities, clarify their rigidity and flexibility characteristics in the sea space, and determine their attribute classification by analyzing the design, purpose and operation of the functional components; Based on the attribute classification of functional components, their exclusive demand for marine resources is evaluated, and then the exclusivity intensity level is divided. Among them, rigid components are classified as high exclusivity, and flexible components are divided into medium and low exclusivity according to their degree of dependence on space and sharing ability. According to the exclusivity strength of functional components, the potential risks of spatial conflicts are identified. Among them, high-exclusivity components have a high risk of spatial conflicts with other sea-use activities due to their strong exclusivity of space and require key planning and management. The spatial conflict risk of medium-exclusivity components is relatively low and still needs to be reduced through reasonable layout and coordination mechanisms. The spatial conflict risk of low-exclusivity components is the lowest and can be compatible with other sea-use activities through shared space. Then, combined with the three-dimensional characteristics of the sea space, the distribution of different functional components in the vertical space is analyzed to identify potential spatial conflict points.

[0009] A further improvement of the technical solution of the present invention is that: S3 includes: Analyze the entire life cycle of each sea-use activity from construction start to operation termination, dividing it into the pre-construction period, operation period, and post-maintenance period. Analyze the start and end times of different operational links within each stage, and determine the position and duration of each link on the timeline. The operation period refers to the period of normal operation of the sea-use activity, while the pre-construction period and post-maintenance period refer to the periods of construction and regular maintenance. Analyze the spatial occupation time characteristics of each type of sea use activity during the initial construction period, operation period, and subsequent maintenance period to determine its temporal continuity or intermittence; According to the temporal characteristics of sea-use activities, the flexibility of the time arrangement of each sea-use activity is evaluated. Among them, the flexibility of long continuous occupation time is low, and the flexibility of obvious intermittent occupation time is high. Then, a comprehensive conclusion on the temporal flexibility of each sea-use activity is formed through integration.

[0010] A further improvement of the technical solution of the present invention is that: S4 includes: Analyze the degree of dependence of each sea-use activity on the water surface, water body, seabed, and subsoil, and identify the main occupied spaces. If the main spaces of two sea-use activities overlap, they are deemed incompatible and such combinations are eliminated. Based on the results of spatial dependency analysis, a preliminary discriminant matrix of vertical compatibility was constructed with sea-use activities as rows and vertical spaces as columns. The matrix was used to identify activity combinations with overlapping main spaces. Based on the preliminary vertical compatibility judgment matrix, a compatibility assessment is conducted on each combination of sea-use activities. According to the standards and rules set by the matrix, activity combinations with preliminary compatibility are screened out to form a preliminary compatible combination list, narrowing the judgment scope of subsequent in-depth analysis and improving screening efficiency.

[0011] A further improvement of the technical solution of the present invention is that the process of compatibility evaluation is: Based on the preliminary judgment matrix of vertical compatibility, the core standards and quantitative rules set by it are sorted out, and the compatibility judgment basis of different sea-use activities in the dimensions of spatial occupation, temporal distribution and resource demand is clarified, including whether the spatial occupation overlaps, whether the temporal distribution conflicts and whether the resource demand is complementary. At the same time, the quantitative indicators and comprehensive scoring methods of each dimension are determined. Among them, the quantitative indicators of each dimension are the spatial occupation overlap rate, the temporal conflict rate and the resource complementarity index. The spatial occupation overlap rate calculates the ratio of the overlapping area of ​​two sea-use activities in the sea area to the total area. The overlap rate ≤ 10% is considered high compatibility, with 5 points, and 10% < heavy compatibility is considered low compatibility. An overlap rate of ≤30% indicates medium compatibility, with a score of 3 points; an overlap rate of >30% indicates low compatibility, with a score of 1 point; the temporal conflict rate calculates the ratio of the time overlap between two sea-use activities to the total time; a conflict rate of ≤10% indicates high compatibility, with a score of 5 points; a conflict rate of 10% < conflict rate ≤30% indicates medium compatibility, with a score of 3 points; a conflict rate of >30% indicates low compatibility, with a score of 1 point; the resource complementarity index assesses the degree of complementarity between the resource demands of two sea-use activities; a complementarity index of ≥0.8 indicates high compatibility, with a score of 5 points; a complementarity index of 0.5 ≤ complementarity <0.8 indicates medium compatibility, with a score of 3 points; and a complementarity index of <0.5 indicates low compatibility, with a score of 1 point; According to the standards and rules of the discriminant matrix, the compatibility of all combinations of sea use activities is evaluated. For each combination, a multiple-dimensional analysis is conducted and a compatibility score is obtained based on the set quantitative indicators. Based on the compatibility assessment results and the discrimination threshold set by the preliminary vertical compatibility discrimination matrix, combinations of sea use activities with preliminary compatibility are screened out. The screened combinations are sorted and summarized to form a preliminary compatible combination list, and the specific composition of each combination is clarified. At the same time, the combinations that fail the screening are recorded and analyzed, and the main reasons for their incompatibility are summarized.

[0012] A further improvement of the technical solution of the present invention is that: S5 includes: A comprehensive database is formed by combining the spatial dependency matrix, functional component exclusivity, and temporal flexibility data. The spatial dependency matrix identifies the primary and secondary space occupied by sea activities, the functional component exclusivity assesses its rigidity and flexibility characteristics, and the temporal flexibility analyzes the duration of sea activities and their ability to adjust at different stages. Based on a comprehensive database, a vertical compatibility discrimination model is constructed to simulate the spatial occupancy of different combinations of sea-use activities and identify potential spatial conflict points. Furthermore, the severity and coordination of conflicts are assessed by combining functional component exclusivity and temporal flexibility. The vertical compatibility discrimination model is used to simulate spatial conflict scenarios under various combinations of sea use activities, analyze the compatibility performance of each combination, and optimize the model parameters and rules based on the simulation results to improve the accuracy and practicality of the model.

[0013] A further improvement of the technical solution of the present invention is that: S6 includes: Extract compatible combinations initially screened by the preliminary discriminant matrix of vertical compatibility, clarify the specific composition of each combination, and conduct a sea use safety factor analysis on the initially screened compatible combinations. The analysis content includes but is not limited to: the impact of sea use activities on the marine ecological environment, the potential risks to the safety of other sea use activities, and the impact on the overall safety of the sea area; Based on the analysis results of sea use safety factors, the preliminary compatibility combinations are adjusted and incompatible sea use activity combinations are removed from the preliminary compatible combination list. For sea use activity combinations that pose safety risks, their compatibility scores are lowered or directly determined to be incompatible. For combinations with high safety, their original compatibility scores are maintained. The compatibility analysis results after sea use safety verification and adjustment will be summarized to form a final multi-dimensional vertical compatibility combination list of sea use activities, and the final multi-dimensional vertical compatibility combination of sea use activities will be output to clarify the specific composition, compatibility score and safety analysis results of each combination, as well as the analysis of the incompatibility reasons for the combinations that failed the screening.

[0014] Due to the adoption of the above technical solution, the present invention has the following technical advancements compared to the prior art: The present invention provides a multi-dimensional method for distinguishing the vertical compatibility of marine activities in sea areas. By comprehensively analyzing marine activities from multiple dimensions such as spatial dependence, functional component exclusivity, and temporal flexibility, the method can accurately identify the compatibility of different marine activities in vertical space, avoid resource waste and conflicts caused by spatial overlap in the traditional planar management model, realize refined management and efficient utilization of marine space, significantly improve the utilization efficiency of marine resources, meet the needs of more marine activities, and promote the sustainable development of the marine economy.

[0015] The present invention provides a method for distinguishing vertical compatibility combinations of multi-dimensional sea area activities. By constructing a comprehensive database and a vertical compatibility distinction model, and combining multi-dimensional data such as a spatial dependency matrix, functional component exclusivity, and temporal flexibility, the method can dynamically simulate spatial conflict scenarios under different combinations of sea area activities, provide objective compatibility assessment results, and provide strong technical support for sea area management, reducing interference from human factors and improving the objectivity of management decisions.

[0019] Example 1, as Figures 1 to 4 As shown, the present invention provides a multi-dimensional sea area use activity vertical compatibility combination judgment method, comprising the following steps: S1. Based on the database of sea-use activities in the sea area, determine the types of sea-use activities involved in the identification, analyze the spatial dependence of each activity on the sea area's water surface, water body, seabed, and subsoil, construct a sea-use activity spatial dependence matrix, identify the main occupied space and the additional occupied space, sort out and screen the types of sea-use activities to be identified based on the database of sea-use activities in the sea area, clarify their development and utilization characteristics and sea area space requirements, analyze the vertical spatial dependence of each type of sea-use activity on the sea area's water surface, water body, seabed, and subsoil, and divide the main occupied space (long-term high dependence) into the additional occupied space (intermittent low dependence), forming a detailed description of the spatial dependence relationship, and construct a sea-use activity spatial dependence matrix based on the analysis results. Combined with the functional characteristics of the sea-use activities and the spatial occupation range, clarify their main occupied space and additional occupied space, providing a spatial stratification basis for vertical compatibility identification; The specific work content is as follows: extract information from the marine activity database, sort out and screen out the types of marine activities that need to be identified, including but not limited to fisheries, port shipping, industrial development, renewable energy utilization, submarine pipeline laying, etc., analyze the development and utilization characteristics and marine space requirements of each type of marine activity, clarify its specific application methods in the marine area and the degree of dependence on spatial resources, and form a comprehensive and detailed list of marine activities; for each type of marine activity, analyze its vertical spatial dependence on the marine surface, water body, seabed, and subsoil; based on the degree of dependence, divide the space occupied by marine activities into main occupied space (long-term high dependence) and auxiliary occupied space (intermittent low dependence), form a detailed description of spatial dependence relationships, and clarify the occupation characteristics and intensity of each type of marine activity in different vertical spaces; based on the analysis results, construct a marine activity spatial dependence matrix, using the marine vertical space (water surface, water body, seabed, subsoil) as dimensions and the type of marine activity as elements, to clarify the main occupied space and auxiliary occupied space of each marine activity; The matrix is ​​refined and improved based on the functional characteristics and spatial occupancy range of sea-use activities to ensure that it accurately reflects the vertical space occupancy relationship of various sea-use activities and provides a clear spatial stratification basis for vertical compatibility judgment. Among them, the development and utilization activities of the water surface layer mostly rely on the physical accessibility and environmental stability of the transition layer between seawater and air. Physical accessibility refers to the ability of sea-use activities to safely and conveniently enter and utilize the surface space of the sea area. Environmental stability includes hydrological conditions and meteorological factors, which will directly affect the safety of facilities and the continuity of operations. For example, activities such as tourist entertainment, ship navigation and berthing require open water areas, and the use of space has high requirements for hydrological conditions such as water depth, waves, and ocean currents. For example, waterways need to avoid areas with dense reefs and choose open water surfaces for ship navigation and avoidance. Harbors, as safe havens for ships to dock, are generally located in inner bays or sheltered sea areas with relatively calm seas and little impact from typhoons. Marine recreational activities have more stringent requirements on environmental stability. Beaches and marine sports areas require calm waters and good weather conditions to ensure the personal safety and comfortable experience of tourists. The development and utilization of water layers mostly rely on the openness of their space, chemical properties and ecological environment. Water space provides a basic carrier for various sea activities. For example, marine fisheries require a sufficiently deep water space to maintain the growth of fish. Discharge, dumping and other activities rely on the fluidity and diffusion capacity of water bodies to reduce local marine environmental pollution. In addition, some sea activities have a special dependence on the ecological environment and chemical properties of water space. For example, marine aquaculture needs to select a suitable water depth according to the habits of the target organisms. It is also highly dependent on factors such as seawater temperature, oxygen content and nutrients. The development and utilization of the seabed layer mostly depends on its topography, Seabed sediment and its stability. Most sea activities that rely on seabed space require flat topography. Artificial reefs, seabed cages, etc. need to be placed on a flat seabed. Linear projects such as optical cables and pipelines laid on the seabed should also give priority to areas with gentle slopes and stable bottom sediments to reduce difficulty and maintenance risks. Secondly, in terms of seabed sediment and its stability, there are several typical types of seabed sediments, including sandy, silt, and bedrock. Sandy sediments have strong permeability and are conducive to the habitat and growth of marine organisms such as shellfish, shrimps and crabs. Silt-type sediments have fine particles and are rich in organic matter. They are the natural bait of many marine organisms and are suitable for the development of mud clams, razor clams, and some low-salt-tolerant fish farming. Ecological projects such as artificial reef deployment and seagrass bed transplantation need to give priority to sand-mud mixed sediments that are conducive to reef stability to rebuild benthic communities. Bedrock-type subsoil has a strong bearing capacity and is resistant to erosion, providing a stable foundation for oil and gas platforms, wind power generation platforms, etc., to prevent the platforms from overturning. The development and utilization of the subsoil layer mostly depends on its geological structure and resource endowment conditions. The construction process of marine engineering projects such as submarine tunnels and cross-sea bridges is closely related to the submarine geological conditions. The subsoil type directly affects the design and construction difficulty of the engineering foundation. For example, in hard bedrock areas, the subsoil has high strength and low permeability, which can provide stable support for submarine tunnels. In soft muddy areas, the subsoil has low bearing capacity and is prone to deformation. Generally, more support structures are required, which increases the difficulty and cost of submarine tunnel construction. In addition, the subsoil is a reservoir of strategic resources such as oil, gas, minerals, geothermal energy, and natural gas hydrates. Its resource endowment and spatial distribution directly determine the location of development activities. Spatial dependence reflects the "priority" or even "exclusivity" of sea-use activities in the selection of vertical space. However, the fact that sea-use activities are highly dependent on a certain layer of sea-use space does not mean that they have no demand for the use of space on other layers. It is just that the frequency and scope of use of space on other layers are relatively small and cannot be ignored. Therefore, the vertical space occupied or disturbed by sea-use activities is divided into primary space and secondary space according to the degree of dependence. Primary space refers to space that is highly dependent on sea-use activities and requires long-term and large-scale occupation. Secondary space refers to space that is less dependent on sea-use activities and requires intermittent or small-scale occupation. S2. Classify the functional components of each type of marine activity, analyze the rigidity and flexibility of their spatial occupancy, and determine the strength of exclusivity. Disassemble the functional components by type of marine activity, including personnel, mobile equipment, vessels, facilities, and structures, and clarify the functional positioning and spatial distribution characteristics of each functional component. By analyzing the correlation between functional components, define their occupation range on the water surface, water body, seabed, and subsoil to form a spatial occupancy baseline. Based on the spatial occupancy requirements of the functional components, distinguish between rigid (fixed position, non-adjustable) and flexible (movable, shareable) attributes. Combined with the functional components' exclusive demand for marine resources, evaluate their exclusivity strength and determine the exclusivity strength level, which is divided into high, medium, and low. Identify the potential risk of spatial conflict. Summarize the attribute classification and exclusivity strength of each functional component to form a marine activity spatial occupancy attribute map. Based on the map, analyze the vertical compatibility of different activities and clarify the spatial hierarchy that can be shared or requires isolation. In addition, the process of determining the level of exclusivity strength is: Classify the attributes of the functional components of various sea-use activities and clarify their rigidity and flexibility characteristics in the sea area space. Rigid components refer to facilities with fixed positions and difficult to adjust. Their space occupation is exclusive and they have a strong demand for exclusive use of sea resources. Flexible components refer to facilities that are movable and can share space with other activities. By analyzing the design, purpose and operation of functional components, their attribute classification is determined. Based on the attribute classification of functional components, their exclusive demand for sea resources is evaluated and then divided into exclusivity intensity levels. Among them, rigid components are classified as high exclusivity. Due to their fixed position and non-adjustability, they have a strong exclusivity for space and are prone to spatial conflicts. Flexible components are divided into medium and low exclusivity based on their degree of dependence on space and sharing ability. Low exclusivity components can share space with other activities and have a low demand for exclusive use of sea resources. Medium exclusivity components can share space with other activities under certain conditions, but reasonable planning is required to avoid conflicts. Based on the exclusivity intensity of functional components, the potential risks of spatial conflicts are identified. Among them, high-exclusivity components have a high risk of spatial conflict with other sea-use activities due to their strong exclusivity of space and require key planning and management. Medium-exclusivity components have a relatively low risk of spatial conflict and still need to be reduced through reasonable layout and coordination mechanisms. Low-exclusivity components have the lowest risk of spatial conflict and can be compatible with other sea-use activities through shared space. Then, combined with the three-dimensional characteristics of the sea area, the distribution of different functional components in the vertical space is analyzed to identify potential spatial conflict points. The specific work content is as follows: for various types of sea-use activities, systematically disassemble their functional components and divide them into personnel, mobile equipment, vessels, facilities and structures (Table 1), clarify the specific functional positioning of each component, such as aquaculture facilities and fishing operation areas in fishery seas, analyze the distribution characteristics of each functional component in the vertical space of the sea area (water surface, water body, seabed, subsoil), analyze the correlation between components, determine their reasonable layout and occupation range in the water area, form the spatial occupation baseline of each functional component, and clarify its specific position and boundaries in different vertical spaces. Among them, the occupation and disturbance of vertical space by sea-use activities are related to the physical entities involved in the sea-use activities. These physical entities are the functional components of sea-use activities. The various spatial behaviors generated by functional components according to certain rules include functional performance, spatial position changes, and interaction with the surrounding environment. The "occupancy" of space is achieved through static and dynamic methods: first, the functional component itself has a certain volume, and its volume has a direct impact on the size of the occupied space. This space occupation method is completely exclusive, such as cross-sea bridges, seawalls, offshore wind power and other structures, equipment or facilities; second, the displacement of the functional component changes with time, and the range enclosed by the movement trajectory of the functional component is also the space it occupies. This space occupation method is relatively exclusive, such as harbors, waterways, etc. Even for the same type of sea-use activities, the vertical space of the sea area occupied or disturbed by different functional components may be different, and then the functional components are summarized as personnel, mobile equipment, ships, facilities and structures; according to the space occupation requirements of the functional components, their rigid (fixed position, non-adjustable) and flexible (movable, shareable) properties are distinguished. Rigid attribute components usually have strict requirements on location, such as port terminals; flexible attribute components have a certain degree of flexibility, such as floating aquaculture platforms. Combined with the functional components' exclusive demand for marine resources, their exclusivity strength is evaluated and divided into three levels: high, medium, and low. High-exclusivity components have strong exclusivity for space occupation and are prone to cause spatial conflicts. Low-exclusivity components can share spatial resources with other activities. The potential risks of spatial conflicts of each functional component are clarified. Different functional components have different spatial usage characteristics due to their own attributes, which affects the compatibility of marine activities in vertical space use. For example, functional components such as "tourists" and "fishing boats" are highly mobile and can be deployed according to actual conditions. The space they occupy can be compatible with short-term or small-scale use by other marine activities under certain conditions. This type of functional component is "flexible"; However, facilities or structures such as "cables," "wind turbines," "tunnels," and "bridges," once built in the marine space, are difficult to move or change. Their occupied space is long-lasting and stable, and generally does not allow interference from other marine activities, which is "rigid." The attribute classification and exclusivity strength of each functional component are summarized to form a marine activity space occupancy attribute map, which displays the distribution characteristics, attribute types, and exclusivity levels of each functional component in the vertical space. Based on the map analysis, the compatibility of different marine activities in the vertical space is clarified, and the spatial levels that can be shared or isolated are identified. For spatial levels with high compatibility, shared utilization models can be explored. For spatial levels with low compatibility, isolation measures need to be formulated to avoid spatial conflicts and ensure the rational use and sustainable development of marine resources. During the implementation of marine activities, flexible functional components are easier to deploy, thereby avoiding or reducing spatial conflicts between marine activities. During the deployment process, rigid components have priority, while flexible components need to be appropriately "sacrificed," that is, they need to obey the deployment when potential conflicts occur.

Analyze the spatial occupancy time characteristics of each sea-use activity during the operation and construction and maintenance periods, identify temporal continuity and intermittency, determine temporal flexibility, analyze the entire life cycle of each sea-use activity from construction start to operation termination, divide it into the early construction period, the operation period, and the later maintenance period, analyze the start and end times of different operational links within each stage, and determine the position and duration of each link on the timeline. The operation period refers to the period of normal operation of the sea-use activity, and the early construction period and the later maintenance period refer to the periods of construction and regular maintenance. The spatial occupation time characteristics of each type of sea-use activity during the early construction period, operation period, and later maintenance period are analyzed to determine its temporal continuity or intermittence. Continuity means that the sea-use activity continuously occupies space during this period, while intermittence means that the sea-use activity only occupies space during a specific time period during this period. Based on the temporal characteristics of the sea-use activities, the flexibility of the time arrangement of each sea-use activity is evaluated. Among them, long continuous occupation times have low flexibility, while obvious intermittent occupations have high flexibility. Sea-use activities with strong temporal flexibility can share space with other activities during non-occupied periods, while sea-use activities with weak temporal flexibility need to occupy specific space for a long time and are difficult to share with other activities. The results are then integrated to form a comprehensive conclusion on the temporal flexibility of each sea-use activity. The specific work content is as follows: for various types of sea-use activities, sort out their entire process from the start of construction to the end of operation, accurately divide the early construction period, operation period and later maintenance period, and break down the different operation links in each stage in detail, clarify the start and end time nodes of each link, and determine the specific position and duration of each link on the timeline through field research, data collection, etc.; analyze the spatial occupation time characteristics of each type of sea-use activity in the early construction period, operation period and later maintenance period, observe its occupation of sea area space in the corresponding period, and judge whether it is continuous or intermittent in time. Continuity means that the sea-use activity occupies space continuously and uninterruptedly in this period, such as some long-term industrial facilities, and intermittence means that the space is occupied only during specific time periods, such as seasonal fishing operations. Through detailed observation and recording of different stages and different activities, the time pattern of their space occupation can be grasped; Based on the temporal characteristics of sea-use activities, the flexibility of the time arrangements of each activity is evaluated. Sea-use activities with long continuous occupation times and fixed time patterns have lower flexibility, while activities with obvious intermittentity and irregular occupation times have higher flexibility. Comprehensive consideration is given to the temporal flexibility of each sea-use activity during the construction and maintenance period and the operation period to form a comprehensive conclusion. It is clear that there are sea-use activities with strong flexibility that can share space with other activities during non-occupancy periods, and sea-use activities with weak flexibility that require long-term fixed occupation of specific space. The process of sea-use activities using sea space includes three stages: early construction, operation and later maintenance. The early construction stage generally includes planning and surveying, construction, temporary facility construction, structure construction, equipment installation and other activities. For example, excavating harbors, installing equipment, building platforms, or laying pipelines and cables generally require large equipment and ships to enter and exit the construction area for a long time or frequently, which has a strong interference intensity on the sea area. The use of space is characterized by concentration, high intensity, and short duration. The later maintenance stage involves equipment replacement and repair, such as wind blade repair, cable repair, channel dredging, etc. Its space use is characterized by localization and intermittence. The vertical space occupied by sea activities in the early construction and later maintenance is called construction and maintenance space; During the operational phase, there are significant differences in the frequency of space occupation by different sea-use activities. Rigid components, such as wind turbine pile foundations, cable ducts, bridge piers, tunnels and other facilities and structures, often occupy fixed sea areas for long periods of time and are characterized by long-term and fixed nature. These components are generally incompatible with other sea-use activities. Flexible components, on the other hand, often occupy sea areas periodically or intermittently, and their operating hours can be appropriately adjusted. For example, ships may intermittently occupy waterways, and tourists and entertainment facilities may occupy rest areas for short periods of time. These types of sea-use activities can allow other sea-use activities to undergo short periods of construction or maintenance, meaning that appropriate "sacrifices" can be made during the conflict coordination process. S4. Based on spatial dependency analysis, eliminate combinations of sea-use activities with overlapping main spaces, construct a preliminary discriminant matrix for vertical compatibility, narrow the discrimination scope, and preliminarily screen compatible combinations. Analyze the degree of dependence of each sea-use activity on the water surface, water body, seabed, and subsoil, and clarify the main occupied spaces. If the main spaces of two sea-use activities overlap, they are judged as incompatible and eliminated. Based on the results of spatial dependency analysis, construct a preliminary discriminant matrix for vertical compatibility with sea-use activities as rows and vertical spaces as columns. Mark the main spatial dependencies of each sea-use activity in the preliminary discriminant matrix for vertical compatibility, define a compatibility judgment framework, and use the matrix to identify activity combinations with overlapping main spaces. Based on the preliminary discriminant matrix for vertical compatibility, conduct compatibility assessments on each sea-use activity combination. According to the standards and rules set by the matrix, screen out activity combinations with preliminary compatibility to form a preliminary list of compatible combinations, narrow the discrimination scope for subsequent in-depth analysis, and improve screening efficiency. In addition, the compatibility assessment process is: Based on the preliminary vertical compatibility judgment matrix, the core standards and quantitative rules set by it are sorted out. The compatibility judgment basis of different sea use activities in the dimensions of spatial occupation, temporal distribution and resource demand is clarified, including whether there is overlap in spatial occupation, conflict in temporal distribution and whether resource demand is complementary. At the same time, the quantitative indicators and comprehensive scoring methods for each dimension are determined; Among them, the quantitative indicators of each dimension are spatial occupancy overlap rate, temporal conflict rate and resource complementarity index. The spatial occupancy overlap rate calculates the ratio of the overlapping area of ​​the two sea-use activities in the sea area to the total area. An overlap rate ≤ 10% is high compatibility, with 5 points, 10% < overlap rate ≤ 30% is medium compatibility, with 3 points, and an overlap rate > 30% is low compatibility, with 1 point. The temporal conflict rate calculates the ratio of the overlapping duration of the two sea-use activities in time to the total duration. A conflict rate ≤ 10% is high compatibility, with 5 points, 10% < conflict rate ≤ 30% is medium compatibility, with 3 points, and a conflict rate > 30% is low compatibility, with 1 point. The resource complementarity index evaluates the degree of complementarity between the two sea-use activities in resource demand. The complementarity index A compatibility score of ≥0.8 is high and is scored 5 points. A complementarity index of 0.5≤<0.8 is medium and is scored 3 points. A complementarity index of <0.5 is low and is scored 1 point. Compatibility assessments are conducted on all combinations of sea use activities according to the standards and rules of the discriminant matrix. For each combination, a compatibility score is obtained by analyzing each combination from multiple dimensions and combining it with the set quantitative indicators. Based on the compatibility assessment results and the discrimination threshold set by the vertical compatibility preliminary discriminant matrix, combinations of sea use activities with preliminary compatibility are screened out. The screened combinations are sorted and summarized to form a preliminary compatible combination list, clarifying the specific composition of each combination. At the same time, combinations that fail the screening are recorded and analyzed, and the main reasons for their incompatibility are summarized.
