Description

Technical Field

[0001] This application relates to the technical field of spatial data processing, and particularly to a method, device, medium, and product for partitioning marine space. Background Art

[0002] Due to the complex and diverse river systems and significant differences in natural environmental conditions in different regions, the water body zoning methods in each region are also different. During this period, water body partitioning was carried out according to a certain characteristic element affecting the water ecosystem. However, the impact on the water ecosystem is generally the result of the combined action of multiple indicators. Therefore, the integrity of the water ecosystem cannot be fully reflected.

[0003] Currently, a water ecological environment function zoning system mainly based on water quality evaluation, water balance analysis, and calculation of water resource carrying capacity has been preliminarily established. The basin water ecological function areas rely on water ecological areas and all target the integrity of the water ecosystem. However, there are differences between the water ecological environment function zoning system of the river system and the basin water ecological function areas. By combining the above two zoning methods, a new water ecological zoning system - the river water ecological function zoning based on the analysis of the water cycle process and the principle of sustainable utilization of water resources - has been formed.

[0037] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

[0038] To make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] In an exemplary embodiment, as Figure 1 shown, a method for partitioning marine space is provided. This method is executed by a computer device, specifically, it can be executed alone by a computer device such as a terminal or a server, or jointly executed by a terminal and a server. The method includes:

[0040] Step 100: Generate a hierarchical evaluation index based on the functional attributes of the marine space. The hierarchical evaluation index includes evaluation objectives, secondary indicators, and tertiary indicators.

[0041] Step 200: Divide the marine space to be partitioned into multiple evaluation units according to a set size, and obtain the original data of the evaluation units.

[0042] Step 300: Obtain the evaluation values and weights of the tertiary indicators based on the original data. Obtain the comprehensive score of the evaluation objective in the evaluation unit based on the evaluation values and weights of the tertiary indicators.

[0043] Step 400: Perform level division based on the comprehensive scores of each evaluation objective in the evaluation unit to obtain the level of each evaluation objective in the evaluation unit.

[0044] Step 500: Use the evaluation objective corresponding to the level of the evaluation objective that meets the set conditions as the partitioning result of the evaluation unit.

[0045] It should be noted that all the embodiments of the method for partitioning marine space provided in the present application can be completed on the ArcGIS platform. That is, the method for partitioning marine space is implemented using the ArcGIS platform.

[0046] As an alternative implementation, in order to comprehensively evaluate the marine space, generating a hierarchical evaluation index based on the functional attributes of the marine space in step 100 includes: dividing evaluation objectives based on the functional attributes of the marine space. The evaluation objectives include marine ecological space, sea area for construction, and space for utilization of marine biological resources. Each evaluation objective is divided into several secondary indicators based on its subordinate functions. Each secondary indicator is divided into tertiary indicators based on the characteristics of the secondary indicator. For the convenience of collation, the above hierarchical evaluation index is tabulated.

[0047] The process of obtaining the evaluation values and weights of the third-level indicators based on the original data in step 300 can be as follows:

[0048] 301. Obtain the evaluation values of the third-level indicators based on the original data.

[0049] 302. Obtain the characteristic proportions of the third-level indicators in the evaluation unit based on the evaluation values of the third-level indicators.

[0050] 303. Obtain the entropy of the third-level indicators based on the characteristic proportions.

[0051] 304. Obtain the weights of the third-level indicators based on the entropy of the third-level indicators.

[0052] In step 300, the multi-factor comprehensive judgment method can be adopted to obtain the comprehensive score of the evaluation target in the evaluation unit based on the evaluation values and weights of the third-level indicators.

[0053] In step 400, the natural breakpoint grading method can be adopted to perform level division based on the comprehensive scores of each evaluation target in the evaluation unit, and obtain the levels of each evaluation target in the evaluation unit.

[0054] In an exemplary embodiment, the marine space zoning method is used, and the implementation manner in the above embodiment is combined to illustrate the zoning of a certain marine space to be zoned as an example. Among them, this embodiment can be implemented on the Arcgis platform.

[0055] S1. Generate the grade evaluation indicators in the manner of step 100 above.

[0056] Divide the evaluation targets based on the functional attributes of the marine space. The marine space has multiple functions, including ecological protection, resource development, and engineering construction, etc. In order to better realize the rational utilization and sustainable development of the marine space, it is necessary to divide the evaluation targets into marine ecological space, sea area for construction, and marine biological resource utilization space according to its main functional attributes and development and utilization directions. This division method can clarify the core functional attributes and development and utilization directions of different marine spaces, and provide a clear target orientation for subsequent detailed evaluation and obtaining the levels of evaluation targets. The obtained evaluation targets include marine ecological space, sea area for construction, and marine biological resource utilization space.

[0057] The membership function based on the evaluation objectives divides each evaluation objective into several secondary indicators. Among them, the basis for dividing secondary indicators is the core functional elements and key features corresponding to the evaluation objectives, that is, the evaluation objectives are divided into several secondary indicators according to the core functional elements and key features belonging to the corresponding evaluation indicators. For marine ecological space, its core functional elements are the ecosystem and ecological environment. Therefore, the secondary indicators of marine ecological space include marine ecosystem, marine ecological environment evaluation, and marine environmental quality. For construction sea-use space, its core functional elements are space resources and development and utilization conditions. Therefore, the secondary indicators of construction sea-use space include marine space resource evaluation, resource and environmental constraint conditions, reclamation stock resources, and traffic superiority. For marine biological resource utilization space, its core functional elements are fishery resources and related environmental conditions. Therefore, the secondary indicators of marine biological resource utilization space include marine fishery resource evaluation, marine environmental quality, marine ecosystem, and maritime traffic superiority. This division method can further refine the evaluation objectives, highlight the key elements of each evaluation objective, and provide a framework for subsequent detailed evaluation and obtaining the levels of evaluation objectives.

[0058] Each secondary indicator is divided into tertiary indicators based on the characteristics of the secondary indicators. The division of tertiary indicators is based on the specific characteristics and practical operability of the secondary indicators to further refine and quantify the specific elements and evaluation contents involved in each secondary indicator. Among them, the selection and definition of tertiary indicators are determined according to existing standards, specifications, and scientific evaluation methods. This method can specifically reflect the connotations and requirements of each secondary indicator. For example, in the marine ecosystem, it is further refined into tertiary indicators such as ecological importance, marine biodiversity, and ecological environment health status. These indicators can quantitatively reflect the characteristics and status of the marine ecosystem through specific calculation methods and evaluation criteria. The above division of tertiary indicators can make the entire hierarchical evaluation index system more scientific, specific, and operable, and can provide a clear quantitative basis for the suitability evaluation of each evaluation objective in the marine space zoning method.

[0059] According to the above description, Table 1 shows the hierarchical evaluation indicators and the explanations for the division basis of each tertiary indicator.

[0063]

[0064] S2. Divide the marine space to be partitioned into multiple evaluation units according to the set size, and obtain the original data of the evaluation units. The evaluation unit is the basic spatial unit for spatial suitability evaluation. Therefore, it is necessary to clarify the size of the evaluation unit and divide the marine space to be partitioned into multiple evaluation units. Conduct a spatial suitability evaluation for each evaluation unit, and then obtain the level of each evaluation objective in the evaluation unit. Based on this, obtain the partition result of the evaluation unit, so as to realize the partition of the marine space to be partitioned.

[0065] Set a reasonable grid cell size as the evaluation unit according to the planning scope. In this application, the dominant factor determination method is mainly adopted, supplemented by the overlay method and the dynamic grid method. Starting from the data availability, the sea area map of the marine space to be partitioned is divided into 1km×1km grid cells as the evaluation units, and data collection and layer analysis operations are carried out according to the above-mentioned grade evaluation indicators.

[0066] S3. Obtain the evaluation values and weights of the third-level indicators based on the original data. Obtain the comprehensive score of the evaluation objective in the evaluation unit based on the evaluation values and weights of the third-level indicators. The entropy weight comprehensive index method is used to determine the weights of each third-level indicator. The entropy weight comprehensive index method is a method for determining the indicator weights based on the information provided by the observed values of each third-level indicator, which can objectively and realistically evaluate the importance of each indicator.

[0067] The entropy weight comprehensive index method specifically includes:

[0068] S31. Organize the original data of each evaluation unit into a matrix X = (x ij ) n×m . Where x ij represents the value of the j-th third-level indicator of the i-th evaluation unit, and m represents the number of third-level indicators.

[0069] S32. Standardize the original data of the evaluation factors of each third-level indicator to form the grid data of each evaluation factor, and use the value at the center point of the grid to represent the score of the evaluation unit in part. In this embodiment, methods such as the extreme value method are used for corresponding standardization processing, which is expressed as: In the formula, x' ij represents the evaluation value of the j-th third-level indicator in the i-th evaluation unit, x ij is the observed value of the j-th third-level indicator, and max(x j ) and min(x j ) represent the upper and lower limits of the observed values respectively.

[0070] S33. Use the formula to obtain the characteristic proportion p ij of the observed value of the j-th third-level indicator in the i-th evaluation unit. In the formula, n represents the number of evaluation units.

[0071] S34, adopt the formula Obtain the entropy e of each third-level index according to the characteristic proportion j .

[0072] S35, adopt the formula Obtain the weight w of each third-level index j .

[0073] In step S3, obtain the comprehensive score of the evaluation target in the evaluation unit based on the evaluation value and weight of the third-level index. Perform weighted summation and superposition operations on the evaluation values and weights of each third-level index in each evaluation unit obtained in the above steps to obtain the comprehensive score of the evaluation target in the evaluation unit.

[0074] Specifically, use the multi-factor comprehensive judgment method to calculate the comprehensive evaluation index of the evaluation target, which is expressed as:[[]]

[0075]

[0076] In the formula, Y i is the comprehensive score of the i-th evaluation unit, w j is the weight of the j-th third-level index, x' ij is the evaluation value of the j-th third-level index in the i-th evaluation unit, and n is the number of evaluation units. The comprehensive score Y i in each evaluation unit can calculate three values, which are the comprehensive scores corresponding to the three evaluation targets respectively. That is, using this formula and according to the evaluation values and weights of the third-level indexes corresponding to each evaluation target in a certain evaluation unit, the comprehensive score of each evaluation target can be obtained (equivalent to the suitability evaluation result of the evaluation target).

[0077] S4, adopt the natural breakpoint grading method, and perform level division based on the comprehensive score of each evaluation target in the evaluation unit to obtain the level of each evaluation target in the evaluation unit. Specifically, perform level division according to the distribution of the comprehensive scores, determine the level of the evaluation target according to the comprehensive scores of the evaluation targets in each evaluation unit, and perform clustering and grading according to the three levels of high, medium, and low to obtain the grading result.

[0078] It should be noted that the comprehensive score of the above evaluation target is equivalent to the suitability evaluation result of the evaluation target in the evaluation unit. The levels of the evaluation targets in the evaluation unit include three levels: high, medium, and low, which respectively correspond to the three grading results of suitability, general, and unsuitability of the suitability evaluation result. Calculating the comprehensive scores of each evaluation target for a certain evaluation unit is to perform a suitability evaluation on each evaluation target in the evaluation unit.

[0079] S5. Take the evaluation objectives corresponding to the levels of the evaluation objectives that meet the set conditions as the zoning results of the evaluation units. According to the grading results obtained in step S4, that is, the levels of the evaluation objectives in the evaluation units, divide the evaluation units.

[0080] For example, if there is only one evaluation objective with a high level in the grading result of a certain evaluation unit, divide this evaluation unit into the spatial type of this evaluation objective. If there are two evaluation objectives with a high level in the grading result of a certain evaluation unit, and if one of the evaluation objectives is the marine ecological space, in principle, this evaluation unit should be divided into the marine ecological space according to the principle of giving priority to ecological protection; otherwise, it can be preferentially divided into the marine biological resources utilization space. If the levels of all three evaluation objectives in the grading result of a certain evaluation unit are high, divide this evaluation unit into the marine ecological space according to the principle of giving priority to ecological protection.

[0081] For the evaluation units where there are no evaluation objectives with a high level in the grading result, if there is only one evaluation objective with a medium level in the grading result of a certain evaluation unit, divide this evaluation unit into this type of space. If there are two or more evaluation objectives with a medium level in the grading result of a certain evaluation unit, it can be determined according to the priority order of marine ecological space - marine biological resources utilization space - sea area for construction use. If the levels of all three evaluation objectives in the grading result of a certain evaluation unit are low, divide this evaluation unit into the marine ecological space according to the principle of giving priority to ecological protection.

[0082] According to the above zoning results of the evaluation units, determine the regional zoning results of the marine ecological space, sea area for construction use, and marine biological resources utilization space in the marine space to be zoned, and obtain the marine space zoning plan for the marine space to be zoned.

[0083] In another exemplary embodiment, taking the zoning of the marine space in Shenzhen, China as an example, in combination with steps S1 to S5 in the above embodiment, it is described. Combining the original marine functional zoning, the "Classification Guide for Land and Sea Use in National Territory Spatial Survey, Planning, and Use Control (Trial)" of China, and the regional current situation and development needs, clarify the small-scale marine space zoning system (as shown in Table 2).

[0084] Table 2 Small-scale marine space zoning system table

[0085]

[0086] Marine ecological space refers to marine space with natural marine attributes and its main functions of providing ecological services, protection and ecosystem maintenance. Construction marine space refers to marine space whose main functions are to undertake marine development and construction activities such as port and port-related industrial development and major infrastructure construction. Marine biological resource utilization space refers to sea areas with good marine environmental quality and high marine primary productivity, which can be used for the supply of marine products, marine biopharmaceutical raw materials, marine tourism, etc.

[0087] The evaluation indicators of Shenzhen’s marine space level and the weights of each third-level indicator are shown in Table 3.

[0088] Table 3 Grade evaluation indicators and weights

[0089]

[0090]

[0091] In the marine ecological space: the marine ecological environment evaluation mainly examines the carrying capacity of the evaluation unit, and evaluates it by comprehensively evaluating indicators such as the marine environmental carrying index and the marine ecological carrying index. The marine ecosystem evaluation focuses on the evaluation of ecological importance, so as to highlight the regulatory role of natural ecosystems, and considers factors such as marine biodiversity and the health status of the ecological environment to comprehensively evaluate the marine ecosystem. The marine environmental quality is a direct reflection of the current status of the sea area, and is mainly evaluated by indicators such as seawater quality. Based on the specific evaluation of the above three aspects, the suitability evaluation results of the marine ecological space are obtained.

[0092] In the construction sea space: comprehensive evaluation of marine space resources, resource and environmental constraints, and the degree of reclamation demand, focus on the spatial distance between the unit and the reclamation built-up area, the spatial location characteristics of the settlement and the marine industry agglomeration area, the proximity to the port conditions, the main traffic arteries and other factors, avoid the terrain restriction areas such as high-slope coasts that are difficult to use for reclamation or construction seas, and conduct a comprehensive evaluation of the suitability of the construction sea space for the entire sea area. In addition, during the evaluation process, it was found that compared with the marine functional zoning, some of the existing sea areas used for construction are not very suitable as construction sea space. For the existing small areas in the current marine functional zoning and the marine construction seas with little potential for future expansion, they should be gradually withdrawn.

[0093] Comprehensively evaluate the suitability of marine biological resource utilization space from the aspects of marine fishery resources, marine environmental quality, marine ecosystem, and maritime transportation advantages.

[0094] Combining the above evaluation results, the zoning scheme of the ocean space is obtained, as shown in Table 4.

[0095] Table 4 Ocean space division table

[0096]

[0097]

[0098] From the perspective of the integrity of spatial units or ecosystem units, the suitability evaluation of small-scale marine space conducts local evaluation, with a certain degree of spatial limitation. Therefore, the final result of the determination of marine space zoning needs to be further verified. According to the upper-level plans such as spatial planning and coastal zone planning, the results of marine space zoning are adjusted to avoid conflicts. After the three-zone plan is delimited, based on the small-scale marine space zoning system, the specific layout of marine functional zoning is proposed.

[0099] Based on the suitability evaluation of marine ecological space construction space, suitability evaluation of sea-use construction space, and suitability evaluation of marine biological resource utilization space, combined with the marine space determination criteria, the marine space zoning plan of Shenzhen City is obtained. And on this basis, the layout of marine functional zoning is delimited.

[0100] Combined with the above embodiments, the present application has the following advantages:

[0101] 1. Innovation in comprehensive evaluation of multiple types of space.

[0102] It breaks through the limitations of the previous single-functional zoning evaluation, incorporates multiple spatial types such as marine ecology, sea-use construction, and marine biological resource utilization into the same evaluation framework for comprehensive evaluation, realizes the all-round and systematic evaluation of marine space, and provides a more comprehensive and overall perspective for marine space planning and management.

[0103] 2. Innovative construction of the evaluation index system.

[0104] The constructed evaluation index system combines the characteristics of the ocean itself, selects targeted evaluation indexes for different types of marine space, such as the marine ecological carrying index in marine ecological space, the shoreline development intensity and sea area development intensity in sea-use construction space, etc. These indexes can accurately reflect the key characteristics of each type of marine space and provide strong support for accurate evaluation.

[0105] 3. Innovative integration of zoning determination principles.

[0106] In the process of zoning determination, multiple principles such as the principle of giving priority to ecological protection, the principle of main functional orientation, and the principle of spatial concentration are integrated. These principles are comprehensively applied according to different suitability situations to determine the zoning type, which not only pays attention to ecological environmental protection but also takes into account the reasonable development and utilization of marine space and the optimization of functional layout, realizing the balance and coordination of multiple goals and providing new ideas and methods for marine space zoning.
