[0042] See Figure 1This is a flowchart illustrating a method for urban vertical master planning provided by an embodiment of the present invention. The method is specifically executed through steps S11 to S14:

[0043] S11. Obtain the current status and planning data of the target city;

[0044] S12. Based on the existing basic data and the planning basic data, determine the minimum construction elevation of each area in the target city based on the flood risk assessment;

[0045] S13. Under the constraint of the minimum construction elevation, the target city is divided into vertical planning zones according to the preset zoning elements and zoning principles;

[0046] S14. Develop corresponding partition control strategies for each of the vertical planning partitions.

[0047] In this embodiment of the invention, flood safety is the core focus, and the vertical planning of the entire city is coordinated through the integration of data across the entire area and hierarchical management.

[0048] Specifically, the first step is to collect basic current data and basic planning data for the target city. The collection of basic current data aims to comprehensively gather information related to the vertical planning, providing a solid data foundation for subsequent analysis and planning. The collection of basic planning data aims to grasp future planning and gather various planning information to ensure that the vertical planning is consistent with the city's overall development goals.

[0049] Next, after acquiring the aforementioned data, a preliminary analysis and summary of the existing basic data and the planning basic data are conducted. Based on the analysis and summary results, a comprehensive analysis of the entire mega-city and super-large city is performed to form comprehensive vertical master planning information. This includes determining the minimum construction elevation for each area in the target city, dividing the target city into vertical planning zones, and formulating differentiated zoning control strategies for each vertical planning zone. This analysis process will fully consider the needs of urban flood safety and combine them with the actual situation of urban development.

[0050] It should be noted that the minimum construction elevation, also known as the baseline elevation, refers to the lowest vertical control elevation set for construction land in urban planning to ensure safety, functional coordination, and landscape requirements. It primarily addresses issues such as terrain undulations, drainage and flood control, and earthwork balance through scientific elevation design, thereby achieving the safe and efficient use of urban space. Elevation refers to the vertical height of a point relative to a reference plane, used to describe the vertical positional relationship of terrain, buildings, roads, etc.

[0051] The determination of the minimum construction elevation aims to ensure the safety of urban infrastructure and residents' lives and property under extreme flooding events, and to enhance the city's flood control and drainage resilience. The division of vertical planning zones and the formulation of zone control strategies aim to achieve refined vertical management of the city, and to formulate differentiated vertical control requirements and development strategies based on the characteristics of different areas.

[0052] Compared to existing methods that only focus on adjusting the elevation of small areas, this invention, employing the technical means of its embodiments, takes flood safety as its core and conducts systematic vertical master planning for the entire area of ​​megacities and super-large cities. Through comprehensive acquisition and analysis of current and planning baseline data, it plans the baseline elevation of each area of ​​the city, zons the vertical planning, and formulates zoned control strategies. This enables vertical planning and overall coordination of the entire city, solves the problem of fragmented vertical planning in megacities and super-large cities, improves the efficiency of urban space resource utilization, and effectively responds to flood disasters.

[0053] For a preferred embodiment, see Figure 2 This is a flowchart illustrating a preferred method for urban vertical master planning in an embodiment of the present invention. The embodiments of the present invention are further implemented based on the above embodiments, and the specific implementation process of each step is further optimized.

[0054] The existing basic data includes: topographic data, river system data, built-up area distribution data, major municipal infrastructure distribution data, and cultural relic protection distribution data.

[0055] The topographic data includes detailed topographic elevation information, such as contour lines and DEM (Digital Elevation Model), used to analyze urban terrain undulation, slope, and catchment areas. The river system data includes the distribution and water level information of existing rivers, lakes, reservoirs, and drainage ditches, used to assess urban hydrological conditions. The built-up area distribution data includes the extent and vertical elevation of existing urban areas, used to analyze the constraints of developed land on vertical planning. The major municipal infrastructure distribution data includes the distribution and elevation information of main roads, bridges, tunnels, underground drainage pipelines, and other infrastructure within the city; the elevation of these facilities has a significant constraining effect on vertical planning. The cultural relic protection distribution data includes the distribution and protection requirements of historical and cultural heritage sites and cultural relics protection units, ensuring that vertical planning does not damage historical features and cultural value.

[0056] The planning data includes: data on planned river systems, data on drainage areas, data on urban road networks, data on territorial spatial planning zones, data on the distribution of major infrastructure, data on urban renewal and renovation plans, and data on stormwater planning.

[0057] The data includes the planned river and canal system, which comprises the layout of rivers, lakes, and drainage systems in the city's future plans, along with planned water levels and drainage standards, to guide future water system construction and flood control and drainage. The drainage area data includes the scope of drainage areas divided by the city according to flood control and drainage needs, as well as the drainage standards and facility plans for each area, providing a basis for regional drainage. The urban road network data includes the city's future planned road network, transportation hubs, etc., along with their planned elevations and slopes, to ensure smooth and safe road traffic. The data also includes territorial spatial planning zoning data: the division of different functional areas in the city's territorial spatial planning, such as residential areas, commercial areas, industrial areas, and green spaces; different functional areas have different requirements for vertical planning. The data on the distribution of major infrastructure includes major infrastructure planned for the city's future, such as newly built transportation facilities, energy facilities, and public service facilities; their planned elevations and layouts have a significant impact on vertical planning. The data on urban renewal and renovation planning includes plans for urban renewal and renovation projects such as the renovation of old urban areas and urban villages; their scope and objectives impose specific requirements on vertical planning. The stormwater planning data includes plans for urban stormwater runoff control, stormwater harvesting and utilization, and sponge city construction, which guide urban stormwater and flood management.

[0058] In a preferred embodiment, after step S11, the method further includes:

[0059] The existing basic data and the planning basic data are preliminarily analyzed and summarized to identify planning elements that have an impact on the city's vertical master plan, so as to compile a preliminary research report on the vertical impact elements of the plan.

[0060] In this embodiment of the invention, a preliminary research report on the vertical influencing factors of planning is prepared based on the acquired basic data on the current status and planning of the city, providing a data foundation for guiding urban staff in carrying out overall vertical planning and control of the city.

[0061] Identifying planning elements that significantly impact vertical planning is a crucial step in ensuring the scientific rigor, rationality, and effectiveness of the plan. By clearly defining the criteria for identifying these elements, we can guide the initial analysis and summarization of planning data, providing a solid foundation for subsequent overall vertical planning.

[0062] By employing the technical means of this invention, a comprehensive and systematic collection and analysis of current status data and planning data is conducted, and a corresponding preliminary research report is prepared, providing a scientific basis for subsequent overall planning.

[0063] As a preferred embodiment, the present invention further implements the above embodiments, wherein step S12, namely, determining the minimum construction elevation of each area in the target city based on the current status data and the planning data and the flood risk assessment, includes steps S121 to S124:

[0064] S121. The area in the target city that belongs to the urban functional attribute is divided into the first area, and the area that belongs to the flood risk attribute is divided into the second area;

[0065] S122. Based on the existing basic data and the planning basic data, conduct a flood risk assessment on the target city and determine the flood control standards and drainage standards for the first area and the second area respectively.

[0066] S123. Calculate the minimum construction elevation of the first area in the target city according to the flood control and drainage standards of the first area;

[0067] S124. Calculate the minimum construction elevation of the second region in the target city according to the flood control and drainage standards of the second region.

[0068] In this embodiment of the invention, the land use attributes of various types of urban land are determined. These attributes include urban functional attributes and flood risk attributes. For example, residential, commercial, industrial, and public facility land uses belong to urban functional attributes, while riverbank, low-lying areas, and flood drainage channels belong to flood risk attributes. Based on these different land use attributes, the various areas within the city are divided into a first area and a second area. The area belonging to urban functional attributes is designated as the first area, and the area belonging to flood risk attributes is designated as the second area.

[0069] Furthermore, based on the city's importance, functional positioning, and flood risk level, flood control and drainage standards for different areas are determined according to professional planning, and these standards are converted into corresponding flood control elevations H. flood and drainage water level H drainage The flood control elevation H is mentioned. flood This refers to the minimum flood control elevation determined according to flood control standards, where the drainage water level H is... drainage This refers to the highest water level for urban flooding determined according to drainage standards. Finally, based on the flood control and drainage standards for different regions, the minimum construction elevation H for different areas in the target city is calculated. min .

[0070] Preferably, the minimum construction elevation is based on the maximum value of the flood control elevation and the drainage water level, and a preset safety height limit H. safetyThe surface runoff height is calculated by summing the surface runoff height and the surface runoff depth, where the surface runoff depth is the minimum surface runoff slope i. min The product of the calculated distance S and the safety height limit H. sαfety This refers to the additional safety height determined based on the city's importance, risk level, and planning requirements. The calculated distance S refers to the distance from the lowest point of the road to the calculation point, which is determined by capturing rainwater drainage points through hydrological analysis.

[0071] Specifically, the formula for calculating the minimum construction elevation of the first area is as follows:

[0072] H min,1 =max(H flood,1 H drainage,1 )+H safety,1 +i min,1 ×S1;

[0073] The formula for calculating the minimum construction elevation of the second area is:

[0074] H min,2 =max(H flood,2 H drainage,2 )+H safety,2 +i min,2 ×S2;

[0075] In this context, subscripts 1 and 2 represent the parameters corresponding to the first region and the second region, respectively.

[0076] It should be noted that during the calculation process, the above flood control and drainage parameters should be differentiated and their values ​​determined based on the characteristics and functional requirements of different land use types (residential, commercial, industrial, public facilities, etc.). For the second area, including riverbanks, low-lying areas, and flood discharge channels, a more stringent baseline elevation will be set. That is, compared to the first area, a higher flood control elevation and drainage water level, as well as a larger safety freeboard, should be adopted: an additional margin should be added to the safety freeboard parameter to ensure absolute safety in extreme situations. In addition, it is necessary to consider the existing topography and engineering measures. For low-lying areas, when determining the baseline elevation, the existing topographic conditions should be taken into account, and the feasibility and economy of necessary engineering measures, such as filling, raising the foundation, and constructing flood walls, should be considered.

[0077] Preferably, the method further includes:

[0078] Compile a baseline elevation map for the entire city, clearly defining the minimum construction elevation control line for each area, which will serve as an important basis for urban construction and planning approval.

[0079] Output the city-wide baseline elevation control map and the minimum construction elevation standards for each area.

[0080] Using the technical means of this invention, and considering the high risk of flooding in megacities and super-large cities, a baseline elevation planning method is proposed to determine the minimum construction elevation of each area of ​​the city based on flood safety, so as to ensure effective flood control and drainage and safeguard urban safety.

[0081] As a preferred embodiment, the present invention is further implemented based on any of the above embodiments, and the preset zoning elements include: topography, hydrological conditions, urban functions, land use planning, flood risk level, geological conditions, and distribution of historical and cultural heritage.

[0082] The topography includes mountains, hills, plains, and waterfront areas; the hydrological conditions include the distribution of rivers, lakes, and wetlands; the urban functions include central urban areas, new towns, industrial parks, and ecological protection zones; and the land use planning includes residential areas, commercial areas, industrial areas, and green spaces.

[0083] Preferably, the principles for zoning are: priority for flood safety, priority for ecology, functional coordination, and protection of historical features.

[0084] The vertical planning zones include primary vertical planning zones and secondary vertical planning zones;

[0085] The first-level vertical planning zones include: built-up areas, incremental construction areas, ecological areas, and agricultural areas; the second-level vertical planning zones include: low-lying areas and standard areas, which are divided by the built-up areas and incremental construction areas according to the minimum construction elevation.

[0086] In this embodiment of the invention, based on the zoning elements and principles, and using GIS spatial analysis, overlay analysis, and other technical means, areas with similar vertical characteristics and planning control needs are delineated, resulting in two levels of vertical zoning. The first-level vertical zoning is divided into built-up areas, incremental construction areas, ecological areas, and agricultural areas. The second-level vertical zoning, based on baseline elevations, further subdivides the built-up areas and incremental construction areas within the first-level zoning into low-lying areas and qualified areas.

[0087] Specifically, the detailed process of vertical planning zoning is as follows: Vertical planning zoning is an important component of the overall vertical planning of megacities and super-large cities. It aims to provide refined management and differentiated guidance based on the vertical characteristics and planning control needs of different areas within the city. Taking into account both current conditions and planning data, areas with similar vertical characteristics and planning control needs are delineated, and corresponding control guidelines are formulated.

[0088] First-level vertical zoning: Based on the land use classification of the overall national land space plan and combined with the vertical planning characteristics of different land use classifications, the entire urban area is divided into four first-level vertical zones:

[0089] Built-up area: This mainly refers to areas of the city that have already been developed and have a high development intensity. Its vertical planning focuses on the renovation of the existing conditions, functional upgrading, and refined management, and needs to give priority to the connection with existing infrastructure and the improvement of the drainage system.

[0090] New construction area: This mainly refers to the newly planned construction land outside the urban built-up area. Its vertical planning focuses on coordination with higher-level plans, rational use of terrain, control of earthwork balance, and reservation of flood control and drainage space.

[0091] Ecological zones: These mainly refer to areas with important ecological functions or high ecological sensitivity, such as mountains, forests, wetlands, and water source protection areas. Their vertical planning should prioritize protection, strictly control development and construction, and minimize disturbance to the natural topography and landforms.

[0092] Agricultural zones: These mainly refer to areas primarily engaged in agricultural production. Their vertical planning focuses on preserving the existing conditions.

[0093] Secondary vertical zoning: Based on the primary zoning, the built-up area and newly developed areas are further divided into secondary vertical zoning according to the baseline elevation and flood risk assessment results.

[0094] Low-lying areas refer to areas where the current elevation is below the baseline elevation or where the risk of flooding is high. These areas require key improvements such as vertical elevation, drainage system upgrades, and flood control infrastructure construction to enhance their flood prevention and drainage capabilities.

[0095] Standardized areas: These refer to areas where the current elevation is higher than the baseline elevation and the risk of flooding is low. Vertical planning in these areas focuses on maintaining the status quo, optimizing drainage, and improving landscape quality.

[0096] As a preferred embodiment, the present invention further implements the above embodiments, wherein the zoning control strategy includes elevation control strategy and slope control strategy for structures, as well as cut and fill engineering control strategy, drainage organization strategy, landscape coordination strategy and ecological protection strategy.

[0097] The elevation control strategy refers to specifying the minimum elevation limits for structures such as buildings, roads, and plazas. The slope control strategy refers to specifying the minimum slope for sites, roads, and green spaces to ensure smooth drainage and safe passage. The cut and fill engineering control strategy refers to limiting large-scale cut and fill projects to reduce damage to the natural terrain and soil erosion. The drainage organization strategy refers to clearly defining the main runoff direction, drainage path, and facility layout for each drainage zone. The landscape coordination strategy refers to ensuring that vertical changes are in harmony with the urban landscape. The ecological protection strategy refers to developing strict vertical protection measures for ecologically sensitive areas.

[0098] Specifically, based on the partitioning strategy development approach, different types of partitioning control strategies are proposed for different partitions:

[0099] The overall vertical planning strategy for the built-up area includes: for areas that meet the standards, vertical planning should be connected to the existing elevation, and local renovations should be coordinated with the surrounding terrain; for low-lying areas, the vertical planning strategy for areas that can be optimized for renovation is to establish an overall and complete elevation control system while meeting basic requirements such as baseline elevation and transportation, and to shape the unique urban landscape; for areas without renovation conditions, drainage problems need to be solved through comprehensive renovation measures.

[0100] The vertical master planning strategy for incremental construction areas includes: coordinating flood control, drainage, and road traffic planning; establishing a comprehensive elevation control system through reasonable terrain modification and comprehensive utilization. Vertical planning in mountainous and hilly areas should emphasize orderly integration with existing construction, optimize earthwork excavation and filling, strengthen the protection of natural landscape features, avoid large-scale excavation and filling, and consider effective measures to prevent geological disasters such as landslides and mudslides. Urban vertical master planning in the main urban area should strengthen the protection of existing construction areas and achieve orderly vertical integration. Urban vertical master planning in plain areas should protect water systems, ponds, and other natural rainwater retention spaces; within the urban development and construction area, rainwater drainage should be guaranteed through vertical planning, while effective engineering measures should be taken to minimize ground subsidence.

[0101] The vertical elevation of the agricultural area is controlled according to the existing vertical elevation.

[0102] The ecological zone's vertical elevation is controlled according to the existing elevation. Roads within the zone must meet drainage requirements, and flood detention areas and natural ponds must be preserved. When linear infrastructure, communication, flood control, and water supply facilities must be constructed that cannot be avoided and must comply with the county-level or higher land use master plan, priority should be given to maximizing the protection of existing landscape and ecological elements, and road elevations should be determined reasonably. For linear infrastructure construction such as roads and water supply in the northern mountainous and hilly areas, the protection of natural landscape features should be strengthened, and large-scale excavation and filling should be avoided. Vertical planning should consider effective measures to prevent geological disasters such as collapses, landslides, and debris flows.

[0103] Preferably, the method further includes:

[0104] Output the first-level vertical planning zoning map, the second-level vertical planning zoning map, and the vertical control guidelines for each zoning.

[0105] By employing the technical means of this invention, cities are divided into different vertical planning zones based on urban characteristics and flood risks, and differentiated vertical control requirements and development strategies are formulated for each zone, which is conducive to achieving refined management.

[0106] As a preferred embodiment, the present invention is further implemented based on any of the above embodiments, and after steps S11 to S14, the method further includes steps S15 to S17:

[0107] S15. Identify special areas within the target city; wherein, the special areas include historical and cultural sites and major infrastructure.

[0108] S16. Correct the minimum construction elevation of the special area; wherein, the correction method is to add a preset redundant elevation to the original minimum construction elevation to obtain the corrected minimum construction elevation;

[0109] S17. An additional adaptive vertical control strategy is added to the special area.

[0110] In this embodiment of the invention, a more adaptable vertical planning strategy is adopted for special areas such as historical and cultural sites and major infrastructure, thereby effectively protecting historical and cultural heritage and ensuring the functional safety of major infrastructure.

[0111] Specifically, the vertical planning strategy for historical and cultural sites includes: assessing the existing topography and drainage systems of the historical and cultural sites, analyzing their flood control capabilities, and identifying the vertical planning zones and baseline elevations of the sites. The principle of "minimal intervention and authentic protection" should be adhered to, avoiding large-scale excavation and filling and destructive construction.

[0112] The vertical control strategy is as follows: Vertical planning prioritizes maintaining the status quo. In areas meeting the standards, vertical design schemes that harmonize with the historical character will be developed, such as employing micro-topographical treatment, infiltrative drainage systems, and preserving existing elevation differences, to ensure drainage functionality while maintaining the historical streetscape and cultural landscape. In low-lying areas, flood control and drainage safety will be ensured through methods such as dredging drainage channels, adding pumping stations, and increasing regional water storage. Renovation and restoration of surrounding areas should take care to prevent water from flowing into these areas.

[0113] Vertical planning strategies for major municipal infrastructure include: in-depth analysis of the functional characteristics, operational requirements, and safety standards of various major infrastructure projects, such as transportation hubs, water supply plants, sewage treatment plants, 500kV substations, gas gate stations, and communication equipment buildings, to clarify the specific vertical baseline elevation requirements for each type of major facility; identifying the vertical planning zones of the land parcels where various major infrastructure projects are located; and calculating the baseline elevation based on the corresponding safety standards for each type of facility to ensure that the construction elevation of the infrastructure is higher than the set baseline elevation requirements, while also considering operational safety under extreme weather conditions.

[0114] The vertical control strategy involves developing detailed vertical control measures, including elevation control during construction and monitoring and maintenance requirements after completion, to ensure the long-term safe operation of infrastructure. For existing facilities located in low-lying areas, the main methods to ensure flood control and drainage safety in the area are dredging drainage channels, adding pumping stations, and increasing regional water storage. Meanwhile, renovations and repairs in surrounding areas should take care to prevent water from flowing into these areas.

[0115] Using the technical means of embodiments of the present invention, the present invention proposes a specific vertical strategy that balances protection and development for special areas and important facilities, ensuring that their functions and values ​​are not affected.

[0116] See Figure 3 This is a schematic diagram of the structure of an urban vertical master planning device provided in an embodiment of the present invention. The embodiment of the present invention provides an urban vertical master planning device 10, comprising:

[0117] Urban basic data acquisition module 11 is used to acquire the current basic data and planning basic data of the target city;

[0118] Minimum construction elevation determination module 12 is used to determine the minimum construction elevation of each area in the target city based on the current basic data and the planning basic data, and on the basis of flood risk assessment.

[0119] The vertical planning zoning module 13 is used to divide the target city into vertical planning zones according to preset zoning elements and zoning principles under the constraint of the minimum construction elevation.

[0120] The partition control strategy formulation module 14 is used to formulate a corresponding partition control strategy for each of the vertical planning partitions.

[0121] Compared to existing methods that only focus on adjusting the elevation of small areas, this invention, employing the technical means of its embodiments, takes flood safety as its core and conducts systematic vertical master planning for the entire area of ​​megacities and super-large cities.
