[0002] The spatial composition of heritage corridors includes the heritage itself and the natural and artificial environment along the line. Compared with other types of heritage, the spatial form along the Grand Canal is more complex and diverse.

The relevant researches on the space along the Grand Canal focus on the historical evolution of towns, the form and distribution characteristics of settlements, the street space landscape characteristics, and the recreational space levels of the river flowing through administrative areas, and there is little research on the control of the continuous and complex spatial form along the line. In terms of research scope, in terms of form research methods, Wang Jianguo and Yang Junyan use comprehensive material space analysis and physical space analysis to comprehensively construct the city-river spatial form system of Hangzhou section. The existing spatial form research scale is small, the spatial type is single, and the canal along the line is mainly focused on single settlement and specific space, mainly focusing on the settlement itself, and lacking research on the linear whole large spatial scale.

[0025] The application is further described below in conjunction with the accompanying drawings and embodiments.

[0026] Embodiments:

[0027] The building height, building density, plot ratio, land use type, style control, and sky openness are selected as the spatial form parameters. The urban-rural cross-sectional model covers various urban and rural space elements in the overall space, such as buildings, plots, land use, and the like of different densities, heights, and form types. Among them, the building height, building density, and plot ratio are the basis for zoning control of building form. In addition, the form criteria are based on the local built-up situation, and the land use and spatial function type are one of the zoning control bases. Compared with two-dimensional planes, the cross-sectional zoning pays more attention to the form characteristics of three-dimensional space, and therefore the sky openness is selected as a parameter to present the spatial form from a three-dimensional perspective. The above parameters aim to quantify the present spatial form, and the planning determines the future spatial form development trend.

[0028] The style control zoning in a certain planning has strong constraint on the future spatial form development. The certain section of the Grand Canal is spatially linked to multiple style control zones, and various types of zoning have a constraint and guidance effect on the shaping of the spatial form along the line, so the style control zoning with future orientation is selected as the spatial form quantification parameter. The application uses ArcGIS 10.2 to analyze, calculate, and visually express the selected research parameters.

[0029] Based on the analysis of different size space units, the detailedness of the spatial differences of geographical things is different. Referring to the existing grid scale division of the spatial distribution of the Grand Canal and the associated urban and rural space along the line, in order to better present the form on both sides of the river, 517 grid units of 1 km*1 km grid are constructed according to the spatial vector data covered by the 1 km buffer zone of the certain section of the Grand Canal, as the minimum spatial scale unit for quantifying the spatial form. Compared with direct community division or road division, the grid method avoids the problem of weak calculation accuracy caused by the size difference of each division unit.

[0030] (1) Land use type. The application team publishes part of the data on basic urban land use mapping in China in a certain year, which is combined with the land area data interpreted by satellite image AI to form the present land use of the corridor space along the certain section of the Grand Canal. The land use type and complexity are one of the bases for dividing the form cross-section zoning.

[0031] (2) Building form. Building form includes building average height, building density and plot ratio. The basic building data contains building height and base area. The total building area is calculated by intersecting building data with the study area using ArcGIS 10.2. In order to present the building form of the overall corridor space along the line in more detail, a 1km*1km fishnet is selected to establish the plot area for calculating building density, plot ratio and building average height. The building data intersected with the study area is connected to the fishnet, and the building form data of the grid cell is obtained by taking the average value in the summary tool. Among them, the building average height is divided into 12 grades according to the average building height in the 1km*1km grid according to the partition requirements of the benchmark height control of the city design guide of a certain city. The building height is converted into the number of layers with a layer height of 3m.

[0032] (3) Sky view factor (SVF). Sky view factor is an important urban form parameter, which refers to the visibility and degree of the sky in a specific location and direction, reflecting the openness of the local space. The value is between 0 and 1, and the closer the value is to 1, the higher the sky openness of the ground point. There are many methods to obtain SVF, among which the grid calculation model is more suitable for rapid calculation of large-scale and large-data urban sky view factor. The present application uses the existing grid calculation model based on high-resolution digital elevation model (DEM) proposed by scholars to estimate SVF. Based on the building Shp data containing height in the study area, the grid and point are created according to the study area using ArcGIS, the building data is intersected with the study area for calculation and analysis, and the SVF value is assigned to the point to obtain the SVF of the calculation area with 2m resolution and R=100m influence radius. Through mean value statistics, it is converted into 1km*1km grid expression.

[0033]

[0034] In the formula, is the sky visible solid angle, unit rad; is the azimuth angle, unit rad; is the first azimuth angle when the terrain influence height angle, unit rad; R is the terrain influence radius, unit m; is the number of calculated azimuth angles.

[0035] (4) Style control. Refer to the style control content of the overall planning of a city, the district planning of a section of the Grand Canal, the control detailed planning of the capital functional core area and the urban sub-center. In various planning documents, although the style zoning expressions are different, the space styles represented have similar characteristics, and are reclassified into 5 style types as shown in Table 1. In the classification process, it is found that the style control in some district planning is not fully covered, and there is no style control requirement in Tongzhou District except for the urban sub-center area, but it is found that the area without style control is mostly ecological green space, which is highly consistent with the first and second green isolation areas of a city. Therefore, the area without style in the research scope is classified as a green ecological style area.

[0036] Table 1. Re-classification of style

[0037]

[0038] The basic data of the research includes Shp data of spatial elements, land use types, and raster images in Table 1. Six spatial form parameters are obtained by GIS processing of the basic data, which are respectively volume rate, building density, average building height, land use type, style control zoning, and SVF. According to the research scope, the fishing net is constructed and projected into the GCS_WGS_1984 geographic coordinate system for analysis.

[0039] In terms of land use, the overall trend is a gradual transition from the two ends of the ecological industry and park green space to the central diversified land use. The blank area in the study area is non-urban construction land such as farmland and forestry. The space along the section of the Grand Canal can be divided into two types of functional sections according to land use: 2 sections of urban comprehensive function and 3 sections of main function. The urban comprehensive function section is connected with multiple green parks, commercial and business districts, cultural heritage, and municipal transportation stations, such as Building 1, Building 2, Building 3, and a certain station. The two urban comprehensive function sections are located in the space along the section of the Grand Canal within the Fourth Ring Road and the urban sub-center function section at the intersection of the North Canal and the Tonghui River on the west side of the East Sixth Ring Road. According to the functional differences, it can be further divided into the inner ring space dominated by administrative and cultural land use, the space between the West Fourth Ring Road and the West Second Ring Road dominated by urban service function, the urban sub-center area, and the space between the East Second Ring Road and the East Fourth Ring Road dominated by business function. The 3 sections of main function space include: the space along the section of the Grand Canal outside the West Fifth Ring Road and outside the East Sixth Ring Road dominated by ecological industry function, the space between the West Fourth Ring Road and the West Fifth Ring Road dominated by park green space, and the space between the East Fourth Ring Road and the urban sub-center dominated by residential function. Land use is one of the factors that affect spatial form, and spatial form is the spatial manifestation of land use. The urban comprehensive function section has diverse functions and variable forms, while the space section with single land use has less form transformation. Based on the division of space sections by land use, the space along the section of the Grand Canal is ranked by the complexity of form: North Canal section < Jingmi Water Diversion Canal section < South Changhe River section < Tonghui River section (East Second Ring Road-East Fourth Ring Road section) < Yuhe-Qian Sanmen Moat section.

[0040] Building form includes building height, floor area ratio, and building density. There are 3 areas along the Grand Canal with high average building height, i.e. the space grid area with an average building height of more than 60m, distributed in the industrial park of the Jingmi Water Diversion Canal section between the West Fifth Ring Road and the Sixth Ring Road, the commercial area along the Tonghui River section of the East Third Ring Road-East Fourth Ring Road, and the Tongzhou urban area at the intersection of the Tonghui River and the North Canal along the East Sixth Ring Road. The average building height of the grid changes little within the Second Ring Road-Fourth Ring Road, mostly within the height range of 24-45m. Due to historical and landscape control requirements, the grid with an average building height of less than 30m is concentrated in the inner ring and the area outside the Sixth Ring Road, accounting for more than two-thirds of the overall study area. In terms of construction intensity, high construction intensity grids are concentrated in the area between the West Fourth Ring Road and the West Second Ring Road outside the Second Ring Road, and between the East Second Ring Road and the East Fifth Ring Road, with sporadic distribution between the East Fourth Ring Road and the Fifth Ring Road. The main functions are industrial parks and business districts. Medium construction intensity grids are mainly distributed in the Second Ring Road-Fourth Ring Road, with large differences in building density between the East Fifth Ring Road and the East Sixth Ring Road, but no high building density grid. The West Fifth Ring Road-West Sixth Ring Road and the area outside the Sixth Ring Road are continuous low building density grids. The floor area ratio between the Second Ring Road and the Fourth Ring Road is generally medium-high, with a small number of high floor area ratio grids distributed in the east, and large areas of low floor area ratio continuous grids in the west of the West Fourth Ring Road and the east of the East Sixth Ring Road.

[0041] The overall sky openness along the Grand Canal is higher, all above 0.70, indicating that the angle of view from the ground is less obstructed by buildings, and the space is more open. The overall sky openness presents a distribution characteristic of high in the east and west and low in the middle, gradually transitioning, and is partly divided by the ring road. The space along the line can be divided into four categories according to the degree of sky openness: first, the high sky openness area with a value above 0.92, which is concentrated in the Jingmi Canal section outside the west fifth ring road and the North Canal section outside the east sixth ring road; second, the two areas with high and low mixed, respectively, the Kunming Lake area between the west fifth ring and the fourth ring, and the Tonghui River section between the east fifth ring and the sixth ring; third, the medium sky openness area, which is distributed in the Jingmi Canal- Changhe section between the west fourth ring and the third ring, and the Tonghui River section between the east third ring and the fifth ring; fourth, the low space openness area below 0.84, which is concentrated in the third ring. Compared with the overall three morphological parameters, high openness space corresponds to the low construction intensity mentioned in the previous text, and the space with ecological and industrial park functions mainly exhibits natural landscape, while low space openness corresponds to high construction intensity in the city, urban comprehensive function and living function mainly, and exhibits the characteristics of urban history and modernization.

[0042] The Grand Canal is a spatial link connecting different urban and rural landscapes, and the two historical landscape areas are located inside the second ring and in the urban sub-center. The landscape types along the line transition from the two ends of the canal and the first green barrier of the Tonghui River passing through the east fifth ring to the two historical landscape areas, and overall present a cross-section of green ecological landscape- production-city integration landscape- modern urban living landscape- historical landscape. The green ecological landscape area is concentrated in the Jingmi Canal section and the North Canal section outside the sixth ring, and the green ecological landscape area and the production-city integration landscape area interweave between the west sixth ring and the fourth ring and the east fifth ring and the sixth ring. The ecological landscape space of Changhe section penetrates into the urban landscape area in a linear manner; the livable living landscape area and the modern urban landscape area are distributed between the fourth ring and the second ring and in the periphery of the historical landscape area in the urban sub-center, which is the main space for coordinating new and old landscapes and exhibiting urban functions. The spatial form is more complex, the former is mostly daily living space, and the latter is more diversified, including administrative office, business and commerce, science and technology innovation industrial park, and other urban comprehensive function space.

[0043] The morphological zoning method of cross-section planning belongs to typology in essence. It is a process of classification and abstraction by extracting relatively fixed elements from a large number of local urban and rural space forms using the "transect method" in morphological criteria. The zoning types derived therefrom can be combined with regional characteristics. By sorting the land use types, average building height, building density, volume rate, sky openness and landscape control type characteristics and spatial distribution along a certain section of the Grand Canal, the six spatial form elements are segmented according to their characteristics, and then integrated to form a summary table of spatial form characteristics along the section, Table 2. Based on the comprehensive consideration of administrative district, river, current land use type, built spatial form characteristics and landscape planning, six types of cross-section morphology are divided, namely, the ecological region, the innovation industrial park, the urban service function region, the business center region, the core historical and cultural region and the special function region. Each type of cross-section selects a morphological sample with a range of 1km*1km to construct a cross-section zoning model of urban morphology along the section of the Grand Canal.

[0044] Table 2 Urban and rural space cross-section morphology analysis along the section of the Grand Canal

[0045]

[0046] By selecting six spatial form parameters suitable for the section of the Grand Canal, using the analysis method combining ArcGIS and typology, the spatial form characteristics along the section are identified, and the cross-section zoning that adapts to the current characteristics of urban and rural space along the section of the Grand Canal is constructed according to the theoretical framework of the cross-section of morphological criteria. The results show that:

[0047] (1) The cross-section model is applicable to the control of the complex and diverse urban and rural space along the section of the Grand Canal, but it cannot be applied mechanically. As the capital, the section needs to bear the core functions, and its core area has particularity, so the space along the section does not present the typical transition space form of natural space-village-town-city. The natural rural space and the innovation industrial park coexist along the section of the Grand Canal, and the high-density and high-intensity building form is not located in the core area within the second ring of the section, but in the external urban service function region and business center region. This shows that the function and form of the space along the section of the Grand Canal are different from the theoretical distribution of urban space form.

[0048] (2) The urban and rural space along the section of the Grand Canal presents differences in different quantitative indicators in the same region. For example, although the business center region has high construction intensity, it has high sky openness and less visual obstruction; while the core historical and cultural region has a lower volume rate than the business center region, due to its high density, it has lower sky openness and weaker spatial openness. The cross-section zoning of morphological criteria takes into account the two-dimensional and three-dimensional multi-form related indicators, and constructs a zoning model that reflects the spatial form characteristics of the urban and rural space along the section of the Grand Canal.

[0049] (3) The urban and rural space along the certain section of the Grand Canal has obvious characteristics of being segmented according to ring lines rather than administrative divisions. The selected morphological quantitative elements are obviously divided by different ring lines, and the segmentation of ring lines is more obvious than administrative divisions. After comprehensive classification, the spatial form cross-section partition still presents the characteristics of high correlation with ring lines.

[0050] The continuous and overall control of the complex urban and rural space along the Grand Canal is the key and difficulty of large-scale linear heritage protection. The present application starts from the perspective of spatial form, uses the morphological criterion cross-section model to form the spatial form cross-section partition along the certain section of the Grand Canal, which is helpful for the continuous control of the urban and rural corridor space form along the Grand Canal at the overall level, has a certain guiding role for the construction of national cultural parks at each level of planning, and has a reference significance for the control of the complex spatial form along the Grand Canal. Specifically, in the research scale, the present application improves the problem of small research scale and insufficient spatial integrity of the key section of linear heritage to some extent, and emphasizes spatial continuity and multifunctionality. In the research method, the present application enriches the quantitative research of the spatial form along the Grand Canal, and uses sky openness as a three-dimensional spatial form analysis element. In addition, the morphological criterion cross-section partition can freely refine types to adapt to specific environments with specific forms, and has strong flexibility and local characteristics. Future research can further refine the cross-section types and morphological control elements and requirements for the complex spatial function form along the canal. It should be noted that the morphological criterion is not used independently, but needs to be attached to the mandatory planning to realize it.

[0051] Therefore, it is necessary to further explore the fusion path of cross-section partition form control and five-level three-type land space planning, and to explore the possibility of parallel form control and use control at the level of regulatory detailed planning. In summary, the morphological criterion cross-section partition control has important significance for the sustainable development of the space along the Grand Canal and the overall development of the city and the national cultural park.

[0052] It should be noted that in the present application, the relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.

[0053] The above examples are only illustrative of the present application and do not constitute a limitation on the scope of protection of the present application, and any design identical or similar to the present application falls within the scope of protection of the present application.
