Description

Technical Field

[0001] The present invention relates to the field of spatial geographic technology, and in particular to a method and system for identifying the spatial morphology of corridors in urban built-up areas. Background Art

[0002] The spatial composition of the heritage corridor includes the heritage itself and the natural and artificial environment along it. Compared with other types of heritage, the spatial form along the Grand Canal is more complex and diverse. It runs through urban and rural spaces and involves multiple natural areas, administrative areas, cultural areas and economic areas. Under a unified development model and time and space scale, how to effectively control the urban and rural space along the Grand Canal has become a major issue that needs to be solved urgently, and it is also one of the important issues in the modernization of national land space governance.

[0003] Based on the intensity and function of spatial protection and control along the Grand Canal, the morphological control zones along the Grand Canal are mostly determined based on the functional sections of the canal, and corresponding control requirements are formulated. In terms of research content, existing research focuses on legislative system guarantees, the path of national cultural park construction, cultural and tourism integration, and the spatial distribution characteristics of heritage sites and projects along the canal. Many scholars have pointed out from different perspectives that relying on rigid zoning control is difficult to be precise and accurate, and the control effectiveness is insufficient. Relevant research on the space along the Grand Canal focuses on the historical evolution of towns, settlement forms and their distribution characteristics, street and alley spatial features, and the recreational space level of the river flowing through administrative areas. There are few studies on the control of continuous and complex spatial forms along the canal. In terms of research scope and morphological research methods, Wang Jianguo and Yang Junyan used comprehensive material space analysis and physical space analysis methods to comprehensively construct the spatial morphological system of the Hangzhou section of Chenghe. The existing spatial morphological research scale is small and the spatial type is relatively single. It is mainly based on single settlements and specific spaces along the canal, focusing on the settlements themselves, and lacks research on linear overall large spatial scales. Summary of the invention

[0004] In order to overcome the shortcomings of the above-mentioned prior art that the spatial morphology research scale is small, the spatial type is relatively single, the focus is on single settlements and specific spaces along the canal, the main focus is on the settlements themselves, and there is a lack of research on linear overall large spatial scales, the main purpose of the present invention is to provide a method and system for identifying the spatial morphology of corridors in urban built-up areas. By using ArcGIS spatial analysis methods, on the basis of analyzing the spatial morphological elements along a certain section of the Grand Canal, a morphological section zoning suitable for the urban and rural corridor space along a certain section of the Grand Canal is established, in order to provide a new research perspective and decision-making reference for the overall refined control of the space along the Grand Canal.

[0005] To achieve the above object, the present invention adopts the following technical solution, a method for identifying the spatial morphology of corridors in urban built-up areas, comprising the following steps: According to the corridor space of the urban built-up area, select the spatial morphological parameters, including land use type, average building height, volume ratio, building density, sky openness and style control; Performing cell division processing on the selected spatial morphological parameters to obtain cell data, performing spatial analysis on the land use types in the cell data to obtain a gradual transition result of the land use types; Based on the cross-section model of morphological criteria, the spatial morphological zoning is performed on the gradual transition results of land use types to obtain the spatial morphological zoning results; The spatial morphological parameters are segmented according to their respective characteristics to obtain segmentation results, and the segmentation results are integrated according to the characteristic type of each morphological parameter segment to obtain a spatial morphological feature set and construct a cross-sectional partition model; The spatial morphology zoning results are spatially located and combined with the corresponding cross-sectional zoning model to obtain the spatial morphology recognition results of the urban built-up area corridors.

[0006] The result of obtaining the gradual transition of land use types includes: The grid unit is subjected to a spatial distribution process of association with the spatial morphological parameters to obtain unit data, including converting the spatial morphological parameters into a grid format, assigning a land use type code to each grid unit based on a classification system of land use types; each grid unit has a height value based on the average building height, and the building density data is represented consistently in the grid unit; based on style and appearance control, confirming the style and appearance control level and category of each grid unit; Select fuzzy logic as the spatial analysis method, use fuzzy logic to process the land use types in the unit data, and obtain a gradual transition result of the land use types.

[0007] The method for obtaining the spatial morphology recognition result of the corridor in the urban built-up area comprises: spatially placing the spatial morphology zoning result in combination with the administrative area, river channel, current land use type, current characteristics of the built spatial morphology and style planning to obtain the spatial placement result, and performing zoning in combination with the cross-sectional zoning model to obtain the spatial morphology zoning result.

[0008] The spatial morphological zoning method adopts a typological method, namely, a transect method.

[0009] A system for spatial morphology recognition of corridors in urban built-up areas, comprising: The data acquisition module is used to determine the research object and select the spatial morphological parameters, including land use type, average building height, volume ratio, building density, sky openness and landscape control; The data analysis module is used to perform cell division processing on the selected spatial morphological parameters to obtain unit data, perform spatial analysis on the land use types in the unit data to obtain the land use type gradual transition result; perform spatial morphological partitioning on the land use type gradual transition result based on the cross-sectional model of the morphological criterion to obtain the spatial morphological partitioning result; perform segmentation processing on the spatial morphological parameters according to their respective characteristics to obtain segmentation results, integrate the segmentation results according to the characteristic type of each morphological parameter segment, obtain the spatial morphological feature set, and construct the cross-sectional partitioning model; The morphological recognition module is used to spatially locate the spatial morphological zoning results and obtain the spatial morphological recognition results of the corridors in the urban built-up area by combining the cross-sectional zoning model.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the key parameters reflecting the urban spatial morphology are identified and processed in the present invention, and the spatial morphology parameters of the corridors in the urban built-up areas are accurately identified and gradually expressed through the accurate identification of the spatial morphology parameters. The spatial morphology zoning is performed based on the morphological criterion cross-sectional model in combination with administrative areas, rivers, current land use types, current characteristics of the built-up spatial morphology and style planning; through spatial morphology zoning, spatial morphology areas with different characteristics are identified, which is helpful for urban planning and style control, and the sample strip method in the typological method is used for spatial morphology zoning to enhance the accuracy and practicality of identification, and the visualization of the gradual transition results of land use types is used to provide urban planners with intuitive spatial morphology change information.

[0011] The present invention can help planners better understand the urban spatial structure, thereby improving the quality and implementation effect of urban planning. The introduction of style and appearance control parameters can help protect and enhance the city's unique style and appearance. It can provide scientific and quantitative decision-making support for urban managers and promote sustainable urban development. The identified spatial morphological zoning can help optimize the allocation of urban land and space resources. By optimizing the spatial morphology of urban corridors, the overall image of the city and the quality of life of residents can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The drawings described herein are used to provide further understanding of the present invention and constitute a part of the present invention. The exemplary embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute improper limitations on the present invention.

[0013] Figure 1 It is a schematic diagram of the process structure of the present invention; Figure 2 It is a schematic diagram of the process of obtaining the gradual transition result of land use type according to the present invention. DETAILED DESCRIPTION

[0014] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0015] Example: Building height, building density, floor area ratio, land use type, style control and sky openness were selected as spatial morphological parameters. The urban and rural cross-sectional model covers a variety of urban and rural spatial elements in the overall space, such as buildings, plots, and land use of different densities, heights, and morphological types. Among them, building height, building density, and floor area ratio are the basis for architectural morphology for zoning control. In addition, the morphological criteria are based on the local existing built conditions, and land use and spatial function type are used as one of the bases for zoning control. Compared with the two-dimensional plane, the cross-sectional zoning pays more attention to the morphological characteristics of the three-dimensional space. Therefore, the sky openness is selected as a parameter to present the spatial morphology from a three-dimensional perspective. The above parameters are intended to quantify the current spatial morphology and plan to determine the future development trend of the spatial morphology.

[0016] The style control zoning in a certain place planning has a strong constraint on the future development of spatial form. A certain section of the Grand Canal connects multiple style control zones in space. Various zones have a constraint and guidance effect on the shaping of the spatial form along the line. Therefore, the style control zoning with future orientation is selected as the spatial form quantitative parameter. The present invention uses ArcGIS10.2 to analyze, calculate and visualize the selected research parameters.

[0017] Based on the analysis of spatial units of different sizes, the spatial differences of geographical objects revealed are of different levels of detail. Referring to the existing grid scale division of the spatial distribution of the Grand Canal and the urban and rural spatial association situation along the Grand Canal, in order to better present the morphology on both sides of the river, a total of 517 grids of 1 km*1 km grid units were constructed based on the spatial vector data covered by the 1 km buffer zone in a certain section of the Grand Canal as the minimum spatial scale unit for quantifying spatial morphology. Compared with direct community division or road division, the grid method avoids the problem of weak calculation results due to differences in the size of each division unit.

[0018] (1) Land use type. Some data on China's basic urban land use mapping published by the inventor's team in a certain year were selected and combined with the land area data after AI interpretation of satellite images. The current land use status of the corridor along a certain section of the Grand Canal was obtained according to the scope of the study area. The type and complexity of the current land use status were used as one of the bases for the morphological section zoning.

[0019] (2) Architectural form. Architectural form includes average building height, building density and floor area ratio. Basic building data includes the height and base area of ​​individual buildings. ArcGIS 10.2 is used to intersect the building data with the research scope and calculate the total building area. In order to present the overall corridor space architectural form along the line in more detail, a 1km*1km fishing net is selected as the plot area for calculating building density, floor area ratio and average building height. The building data that intersects with the research scope is connected to the fishing net, and the average value is taken in the summary tool to obtain the architectural form data of the grid unit. Among them, the average building height is divided into 12 levels according to the requirements of the benchmark height control zoning in the urban design guidelines of a certain city. The present invention converts the building height into the number of floors with a floor height of 3m.

[0020] (3) Sky View Factor (SVF). Sky view factor is an important urban morphological parameter, which refers to the visible range and degree of the sky at a specific location and direction, reflecting the openness of the local space of the city. The value is between 0 and 1. The closer the value is to 1, the higher the sky openness at that point on the ground. There are many methods to obtain SVF, among which the raster calculation model is more suitable for the rapid calculation of urban sky openness with large scope and large amount of data. The present invention adopts the raster calculation model based on high-resolution digital elevation model (DEM) proposed by existing scholars to estimate SVF. Based on the building Shp data with height in the study area, ArcGIS is used to create grids and points according to the study scope, and the building data is intersected with the study scope for calculation and analysis, and the SVF value is assigned to the point to obtain the SVF of 2m resolution in the calculation area with an influence radius of R=100m, and then converted into a 1km*1km grid expression through mean statistics.

[0021] In the formula, is the visible solid angle of the sky, in radians; is the azimuth angle in radians; For the first The terrain influence height angle at the azimuth is in radians; R is the terrain influence radius in meters; is the number of azimuth angles calculated.

[0022] (4) Landscape control. Refer to the landscape control content in the overall urban planning of a certain place, the zoning plan involving a certain section of the Grand Canal, and the control detailed planning of the capital functional core area and the urban sub-center. In each planning document, although the landscape zoning is expressed differently, the spatial landscape represented has similar characteristics and is reclassified into five landscape types as shown in Table 1. During the classification process, it was found that the landscape control in some zoning plans was not fully covered. Tongzhou District had no landscape control requirements except for the urban sub-center area. However, it was found that most of the areas without landscape control were ecological green space, which was highly overlapped with the first and second green belt areas of a certain city. Therefore, the landscape-free space within the research scope was classified as a green ecological landscape area.

[0023] Table 1 Reclassification of landscape The basic data of the study include Shp data of spatial elements of a certain place, land use type, raster images, etc. Table 1 GIS processing of basic data to obtain 6 spatial morphological parameters, namely, floor area ratio, building density, average building height, land use type, style control zoning, and SVF. According to the research scope, the fishing net was cut and constructed, and uniformly projected to the GCS_WGS_1984 geographic coordinate system for analysis.

[0024] In terms of land use types, the overall trend is a gradual transition from the land use types dominated by ecological industries and park green spaces at both ends to the diversified land use types in the middle. The blank areas within the research scope are non-urban and rural construction land such as agricultural and forestry land. The space along a certain section of the Grand Canal can be divided into two functional sections according to the land use type: 2 sections of urban comprehensive function sections and 3 sections of main function sections. The urban comprehensive function section connects multiple green parks, commercial business districts, cultural relics, and municipal transportation stations, such as Building 1, Building 2, Building 3, and a certain station. The two urban comprehensive function sections are located along the space within the Fourth Ring Road and the functional section of a certain urban sub-center at the junction of the Tongyun River and the North Canal on the west side of the East Sixth Ring Road. According to the functional differences, it can be further subdivided into the space within the Second Ring Road dominated by administrative and cultural land types, the corridor space between the West Fourth Ring Road and the West Second Ring Road dominated by urban service functions, and the urban sub-center area and the corridor space between the East Second Ring Road and the East Fourth Ring Road dominated by business. The three main functional space sections include: the space along the line with ecological and industrial functions outside the West Fifth Ring Road and the East Sixth Ring Road, the space along the line between the West Fourth Ring Road and the West Fifth Ring Road with parks and green space as the main function, and the space along the line between the East Fourth Ring Road and the sub-center of a certain city with living as the main function. Land use type is one of the factors affecting spatial form, and spatial form is the spatial manifestation of land use type. The urban comprehensive function section has diverse functions and changeable forms, while the space section with a relatively single land use type has fewer changes in form. Based on the spatial sections divided by land use type, the space along a certain section of the Grand Canal is ranked according to the complexity of the form: North Canal Section < Beijing-Miyun Canal Section < South Changhe Section < Tonghui River Section (East Second Ring Road - East Fourth Ring Road Section) < Yuhe - Qiansanmen Moat Section.

[0025] Building form includes building height, volume ratio and building density. There are three areas with high average building height along the Grand Canal, namely, spatial grid areas with an average building height of more than 60m, which are distributed in the industrial park of the Jingmi water diversion canal section within the West Fifth Ring Road and the Sixth Ring Road, the business district where the Tonghui River section of the East Third Ring Road and the Fourth Ring Road flows through, and the Tongzhou urban area at the junction of the Tonghui River and the North Canal along the East Sixth Ring Road. The average building height of the grid in the Second Ring Road and the Fourth Ring Road circle varies little, mostly in the range of 24-45m. Due to historical and landscape control requirements, the grids with an average building height of less than 30m are concentrated in the areas within the Second Ring Road and outside the Sixth Ring Road, accounting for more than two-thirds of the entire research area. In terms of construction intensity, high-construction intensity grids are concentrated in the areas between the West Fourth Ring Road and the West Second Ring Road, and the East Second Ring Road and the East Fifth Ring Road outside the Second Ring Road in the middle, and are scattered between the East Fourth Ring Road and the Fifth Ring Road. The functions are mainly industrial parks and business districts. The medium-intensity construction grids are mainly distributed between the Second Ring Road and the Fourth Ring Road. The building density of the grids within the East Fifth Ring Road and the East Sixth Ring Road varies greatly, but there are no high-building density grids. The West Fifth Ring Road, the West Sixth Ring Road and the area outside the Sixth Ring Road are continuous low-building density grids. The plot ratio between the Second Ring Road and the Fourth Ring Road is generally medium-high, with a small number of high-plot ratio grids distributed in the east. There are large areas of low-plot ratio continuous grids outside the West Fourth Ring Road and the East Sixth Ring Road.

[0026] The overall sky openness along the Grand Canal is relatively high, all higher than 0.70, indicating that the elevation view from the ground is less blocked by buildings and the space is relatively open. The overall sky openness shows a distribution characteristic of high in the east and west and low in the middle, with a gradual transition, and some parts are divided by the ring line. The spatial segments along the line can be classified into four types of spaces according to the characteristics of sky openness: the first is the high sky openness area with a value above 0.92, which is concentrated in the Jingmi Water Diversion Canal section outside the West Fifth Ring Road and the Beiyunhe section outside the East Sixth Ring Road; the second is two high-low mixed areas, namely the Kunming Lake area between the West Fifth Ring Road and the Fourth Ring Road and the Tonghui River section between the East Fifth Ring Road and the Sixth Ring Road; the third is the medium sky openness area, which is distributed in the Jingmi Water Diversion Canal-Changhe section between the West Fourth Ring Road and the Third Ring Road and the Tonghui River section between the East Third Ring Road and the Fifth Ring Road; the fourth is the low space openness area with a value below 0.84, which is concentrated inside the Third Ring Road. From the overall comparison with the first three morphological parameters, it can be seen that the high openness space corresponds to the space segment with low construction intensity, ecological and industrial park functions as the main features, and showing the natural landscape of mountains and rivers mentioned above, while the low space openness corresponds to the space segment with high urban construction intensity, urban comprehensive functions and living functions as the main features, and showing the city's historical and modern characteristics.

[0027] The Grand Canal is a spatial link connecting different urban and rural landscapes. The two historical landscape areas are located within the Second Ring Road and in the sub-center of the city. The landscape types along the route transition from the first green barrier at both ends of the canal and the East Fifth Ring Road where Tonghui River passes through to the two historical landscape areas. On the whole, it presents a cross-section of green ecological landscape-industry-city integration landscape-modern urban life landscape-historical landscape. The green ecological landscape area is concentrated in the Jingmi water diversion canal section and the North Canal section outside the Sixth Ring Road. The green ecological landscape area and the industry-city integration landscape area are intertwined between the West Sixth Ring Road-Fourth Ring Road and the East Fifth Ring Road-Sixth Ring Road. The ecological landscape space of the Changhe section penetrates into the urban landscape area in a linear manner; the livable life landscape area and the modern urban landscape area are distributed between the Fourth Ring Road-Second Ring Road and the periphery of the historical landscape area in the sub-center of the city. They are the main spaces that coordinate the old and new landscapes and show the functions of the city. The spatial form is relatively complex. The former is mostly daily life space, while the latter is more diverse in content, including administrative offices, business and commerce, science and technology innovation industrial parks and other urban comprehensive functional spaces.

[0028] The morphological zoning method of cross-section planning is essentially typological. It adopts the "strip method" used in the morphological criteria. It extracts relatively fixed content from the elements of the place from a large number of local urban and rural spatial forms. This is a process of classification and abstraction. The derived zoning type can be combined with regional characteristics. By sorting out the type characteristics and spatial distribution of land use types, average building height, building density, volume ratio, sky openness and style control along a section of the Grand Canal, the six spatial morphological elements are segmented according to their characteristics, and then integrated according to the characteristics of each element segment to form a summary table of spatial morphological characteristics along the line, Table 2. Based on the comprehensive consideration of administrative districts, rivers, current land use types, current characteristics of built spatial forms and style planning, six types of cross-sectional forms are divided: landscape ecological area, innovation industrial park, urban service function area, business center area, core historical and cultural area and special function area. Each type of cross section selects a morphological sample with a range of 1km*1km to construct a cross-sectional zoning model of urban morphology along a section of the Grand Canal.

[0029] Table 2 Analysis of the cross-sectional morphology of urban and rural spaces along the Grand Canal (a certain section) By selecting 6 spatial morphological parameters suitable for a certain section of the Grand Canal, using ArcGIS and typology combined analysis methods, the spatial morphological characteristics along the Grand Canal were identified, and according to the morphological criterion cross-section theoretical framework, a cross-sectional partition that is suitable for the current characteristics of urban and rural spatial morphology along a certain section of the Grand Canal was constructed. The research results show that:

[0030] (1) The cross-sectional model is applicable to the complex and diverse urban and rural spatial morphology along the Grand Canal, but it cannot be applied mechanically. As the capital, a certain place needs to assume core functions, and its core area has its own particularity. Therefore, the space along the line of a certain section does not present a typical transitional spatial form of natural space-village-town-city. Natural rural space and innovative industrial parks coexist along the line of a certain section. High-density and high-intensity building forms are not located in the core area within the second ring road of a certain section, but in the urban service function area and business center area outside it. This shows that the spatial function and form along the line of a certain section are different from the theoretical distribution of urban spatial form.

[0031] (2) The different quantitative indicators corresponding to the urban and rural spaces along a certain section of land show differences in the same area. For example, although the central business district has a high construction intensity, the sky is open and the sight is less blocked; while the core historical and cultural district has a lower floor area ratio than the central business district, but due to its high density, its sky is open and the degree of spatial openness is weak. The morphological criterion cross-sectional zoning takes into account two-dimensional and three-dimensional multi-type morphological indicators, and constructs a zoning model that reflects the morphological characteristics of urban and rural spaces along a certain section of land.

[0032] (3) The urban and rural spatial morphology along a certain section of the Grand Canal has obvious segmentation characteristics based on ring lines rather than administrative divisions. The selected morphological quantitative elements are mostly divided by different ring lines, and the segmentation effect of the ring lines is more obvious than that of administrative divisions. After comprehensive classification, the cross-sectional zoning of spatial morphology still shows a high correlation with the ring lines.

[0033] The continuous and overall control of the complex urban and rural spaces along the Grand Canal is the focus and difficulty of large-scale linear heritage protection. Starting from the perspective of spatial morphology, the present invention uses the morphological criterion cross-section model to form a cross-section partition of spatial morphology along a certain section of the Grand Canal, which is helpful to carry out continuous control of the spatial morphology of urban and rural corridors along the Grand Canal at the overall level, and has a certain guiding role in the planning and construction of national cultural parks at all levels. At the same time, it has a reference significance for the control of complex spatial morphology along the Grand Canal. Specifically, in terms of research scale, the present invention improves the problem of small research scale and insufficient spatial integrity of key sections of linear heritage to a certain extent, and emphasizes spatial continuity and multifunctionality. In terms of research methods, it enriches the quantitative research of spatial morphology along the Grand Canal, and uses sky openness as an element of three-dimensional spatial morphological analysis. In addition, the cross-section partition of morphological criteria can be freely refined, adapting to specific environments with specific forms, and has strong flexibility and locality. Future research can further refine the cross-section types and morphological control elements and requirements for the complex spatial functional forms along the canal. It should be noted that morphological criteria are not used independently but must be implemented in conjunction with mandatory planning.

[0034] Therefore, it is necessary to further explore the integration path of cross-sectional zoning morphological control and the five levels and three categories of national land space planning, and explore the possibility of parallel morphological control and use control at the level of regulatory detailed planning. In summary, the cross-sectional zoning control of morphological criteria is of great significance to the sustainable development of space along the Grand Canal and the coordinated development of cities and national cultural parks.
