Description

Technical Field

[0001] This invention relates to a spatial gene identification method, and more particularly to a spatial gene identification method for ancient towns along the Huaiyang Canal from the perspective of the canal transport system, belonging to the field of information extraction technology. Background Technology

[0002] Ancient towns along the Grand Canal are a special type of town formed under the background of long-term water transport activities and institutional operation. Their spatial structure and functional layout are influenced by multiple factors such as transportation, material allocation, and administrative management. The canal region, represented by the Huaiyang section of the Grand Canal, has formed a number of ancient towns with typical water-land composite characteristics during the long-term operation of the canal transport system. Their spatial form has obvious historical continuity and institutional influence.

[0003] In existing practices of ancient town protection and renewal, the understanding of the spatial structure of canal towns is mostly limited to superficial descriptions of features, lacking a systematic analysis of the mechanisms underlying spatial morphology formation. Current techniques typically use the canal transport system as a qualitative explanation of historical background, failing to establish a correspondence between the system's operational mechanisms and spatial structure. This results in a lack of targeted selection of spatial elements and makes it difficult to identify core spatial structural features driven by the canal transport system from the perspective of its operational logic. Furthermore, existing spatial analysis methods often focus on single spatial elements or static morphological features, emphasizing the morphological summarization of individual elements. They lack a systematic analysis of the combination relationships, configuration rules, and formation causes among spatial elements, and have not established stable identification processes and verification mechanisms. Due to the lack of a rule-based analysis of the combination relationships of spatial elements and a screening mechanism for historical stability, it is difficult to identify spatial structural features that have remained stable over long-term evolution and reflect the synergistic interaction between space, nature, and humanity. Consequently, it is difficult to distinguish between spatial genes that should be prioritized for protection and spatial phenomena that have formed in stages or incidentally.

[0004] Therefore, existing technologies lack a systematic analysis of the spatial elements and their combination relationships of ancient towns along the Huaiyang Canal from the perspective of the canal transport system, to establish a corresponding analytical framework between the institutional operation mechanism and spatial structure, and to identify spatial genes with long-term stability and synergy characteristics through a stability and synergy determination mechanism. Summary of the Invention

[0005] Purpose of the invention: The purpose of this invention is to provide a spatial gene identification method for ancient towns along the Huaiyang Canal from the perspective of the canal transport system, which can improve the systematicness, repeatability and scientific nature of spatial gene identification.

[0006] Technical solution: The spatial gene identification method for ancient towns along the Huaiyang Canal from the perspective of the canal transport system, as described in this invention, includes:

[0007] S1: Determine the penetrance of spatial genes in the ancient towns along the Huaiyang Canal, summarize the spatial characteristics of the ancient towns along the Huaiyang Canal, and screen the spatial characteristics based on stability and synergy.

[0008] S2: Determine the set of spatial elements corresponding to the selected spatial features, and select the set of spatial elements related to the canal transport system;

[0009] S3: Match each spatial element in the filtered spatial element set to the corresponding canal transport system analysis dimension;

[0010] S4: Based on the analysis dimension of the canal transport system, analyze the functional characteristics, morphological characteristics and distribution characteristics of spatial elements;

[0011] S5: Based on the analysis dimensions and spatial element analysis results, analyze the configurational relationships between spatial elements, including combination rules and combination reasons;

[0012] S6: Analyze the harmonious and interactive relationship between spatial elements and their configurations in the context of space, nature, and human elements;

[0013] S7: Eliminate spatial element configuration relationships in each spatial element set that do not conform to the harmonious interaction between space, nature, and humanity, and finally determine the spatial genes of the Huaiyang Canal Ancient Town.

[0014] Further, step S1 includes:

[0015] S1.1: Based on publicly available literature, historical images, and field research analysis, the spatial genes of the ancient towns along the Huaiyang Canal were obtained, and the spatial characteristics of the ancient towns along the Huaiyang Canal were summarized.

[0016] S1.2: Combining historical documents and images from different historical periods, the spatial features are subjected to stability screening;

[0017] The stability screening specifically involves screening out spatial features and their corresponding spatial elements that have persisted in different historical periods, and eliminating spatial features that only appear in a single historical period or due to sudden events.

[0018] S1.3: Based on the synergistic interaction characteristics of space, nature and humanities in spatial genes, synergistic screening is performed on spatial features that have undergone stability screening;

[0019] The aforementioned collaborative screening specifically involves screening out spatial features that reflect the collaborative and interactive relationship between space, nature, and humanity under the background of the operation of the canal transport system, and eliminating spatial features that do not possess the aforementioned collaborative and interactive relationship.

[0020] Further, step S2 includes:

[0021] S2.1: Determine the spatial elements involved in each of the selected spatial features as the set of spatial elements corresponding to each spatial feature. , The number of spatial features, For the first A collection of spatial elements with spatial characteristics; the spatial elements include natural environmental elements and artificial environmental elements. The natural environmental elements include canals and lakes, and the artificial environmental elements include streets and alleys, bridges, wharves, buildings, sluice gates, water storage facilities, post stations, river embankments, shops, government offices, customs offices, guild halls, academies, gardens and courtyards, ancestral halls and iron rhinoceroses.

[0022] S2.2: Determine whether the existence of each spatial element in the set of spatial elements is related to the operation mechanism of the canal transport system, and remove spatial elements and their corresponding spatial element sets that are unrelated to the canal transport system.

[0023] The basis for this judgment includes:

[0024] Functional relevance determination, specifically, determines whether the spatial elements correspond to the storage and transportation link, trade link, management link, or cultural link in the operation mechanism of the canal transport system;

[0025] Documentary verification involves determining whether the appearance, scale, or distribution of the aforementioned spatial elements are recorded in local chronicles, canal transport archives, or historical maps in relation to the canal transport system.

[0026] Spatial location determination specifically involves determining whether the spatial element is adjacent to or connected to a canal, wharf, or storage node in terms of spatial location.

[0027] When a spatial element satisfies at least two of the following criteria—functional relevance, documentary corroboration, and spatial location—it is determined that the spatial element is related to the operational mechanism of the Grand Canal system.

[0028] Further, step S3 includes:

[0029] S3.1: Establish analytical dimensions for the Grand Canal system, and construct four analytical dimensions for spatial element analysis based on the operational mechanism of the Grand Canal system; the operational mechanism of the Grand Canal system includes: storage and transportation links, trade links, management links, and cultural links;

[0030] The storage and transportation link is used to reflect the material storage, transfer and dispatch functions of the water storage, dam, wharf and post station along the route;

[0031] The commercial and trade links are used to reflect the trade activities of shops and streets around the dock;

[0032] The management process is used to reflect the administrative supervision functions of the government offices and customs offices.

[0033] The cultural elements are used to reflect the functions of communication and cultural identity among the people associated with the guild halls, academies, gardens, ancestral halls, and iron rhinoceroses.

[0034] Based on the aforementioned storage and transportation, commerce, management, and cultural aspects, four analytical dimensions are constructed: storage and transportation function orientation, commerce and economic drive, river canal system management, and integration of diverse cultures.

[0035] S3.2: Based on the functional positioning of the selected spatial elements, match each spatial element to the corresponding analysis dimension of the canal transport system;

[0036] The spatial elements corresponding to the storage and transportation functions include canals, water warehouses, wharves, post stations, sluice gates, and river embankments. The combination of these spatial elements serves the storage and transportation of goods.

[0037] The spatial elements corresponding to the commercial and trade economy include canals, wharves, shops, streets and alleys, and post stations. The combination of these spatial elements serves trade activities.

[0038] The spatial elements corresponding to the river and canal system management include canals, government offices, wharves, and customs offices. The combination of these spatial elements serves administration and supervision.

[0039] The spatial elements corresponding to the integration of diverse cultures specifically include guild halls, academies, gardens, ancestral temples, and iron rhinoceroses. The combination of these spatial elements serves to facilitate communication, exchange, and cultural identity among different groups of people.

[0040] Further, step S4 specifically involves: analyzing the functional characteristics, morphological characteristics, and distribution characteristics of each spatial element in each spatial element set, based on the corresponding analysis dimension;

[0041] The functional characteristic analysis specifically involves: clarifying the specific roles of spatial elements in the canal transport system, and analyzing the specific ways in which the spatial elements respond to the specific needs of canal transport;

[0042] The morphological feature analysis specifically involves: qualitatively extracting the planar morphology of spatial elements by combining historical documents and video data, and quantitatively measuring the physical scale, area, and capacity of the spatial elements using spatial quantification technology.

[0043] The distribution characteristic analysis specifically involves: determining the specific spatial location of a single spatial element; and using spatial statistical analysis methods to calculate and reveal its distribution pattern, aggregation degree, and spatial orientation in the ancient town space for two or more spatial elements.

[0044] Further, step S5 includes:

[0045] S5.1: Identify the combination rules formed between elements based on their spatial location, directional relationship, connectivity, and adjacency relationship;

[0046] S5.2: Based on the identified combination rules, and combined with the analysis dimensions of the canal transport system matched with the spatial elements, analyze the combination reasons for forming the combination rules.

[0047] Further, step S5.1 specifically involves describing the combination rules between spatial elements within each spatial element set, based on the analysis dimensions corresponding to each spatial element set. The combination rules include parallel relationships, vertical relationships, orientation relationships, primary and secondary relationships, sequence relationships, connectivity relationships, adjacency relationships, inclusion relationships, axis relationships, and center relationships.

[0048] The parallel relationship specifically refers to two or more spatial elements maintaining the same direction.

[0049] The vertical relationship specifically refers to the fact that two spatial elements intersect at a right angle in a direction;

[0050] The orientation relationship specifically refers to the orientation and facing relationship of a spatial element relative to a specific reference direction.

[0051] The primary and secondary relationship refers specifically to the primary and secondary relationship between spatial elements.

[0052] The sequence relationship is specifically a spatial sequence formed between spatial elements through streamlines and positional relationships;

[0053] The connectivity relationship specifically refers to the connection between two spatial elements through one or more paths;

[0054] The adjacency relationship specifically refers to the sharing of one or more boundaries between two or more spatial elements;

[0055] The inclusion relationship specifically means that one spatial entity is completely located inside another spatial entity;

[0056] Specifically, the axial relationship refers to the distribution of spatial elements along a certain axis;

[0057] The central relationship refers to one or more spatial elements occupying a core position in the overall spatial layout, with other elements revolving around them.

[0058] Furthermore, the reasons for the combination mentioned in step S5.2 include meeting the needs of canal transport material storage and transportation, the needs of commercial activity aggregation and circulation, the needs of canal system management and administrative supervision, and the needs of multicultural exchange.

[0059] Further, step S6 specifically involves: analyzing the formation logic of the spatial element configuration relationships identified in step S5 in terms of natural environment adaptation, socio-cultural carrying capacity, and the synergistic effect of nature and humanity; identifying whether the spatial element configuration relationships reflect the coordinated interaction between space, nature, and humanity; and based on the coordinated interaction relationship, extracting the mechanism of action of the spatial genes of the ancient towns along the Huaiyang Canal under the influence of the canal transport system, including:

[0060] S6.1: Analysis of the harmonious interaction between the natural environment and the ancient town space: Combining the morphology, flow direction, water level conditions and topography of the Huaiyang Canal, analyze the adaptation of the spatial elements and their structural relationships of the ancient town to the natural environment in terms of site selection, construction and water conservancy facility setting, and identify the harmonious interaction between the natural environment and the ancient town space.

[0061] S6.2: Analysis of the interactive and coordinated relationship between social culture and ancient town space: Combining the social organizations, economic activities and cultural activities formed under the canal system, analyze the way in which the spatial elements of the ancient town and their structural relationships carry humanistic activities such as commodity trading, administration, daily life and cultural exchange, and identify the coordinated and interactive relationship between social culture and ancient town space.

[0062] S6.3: Analysis of the coordinated interaction between the natural environment and social culture: Combining the supporting role of the canal system in the production, transportation and life of the ancient town, as well as the flood control concept and local cultural identity formed by it, analyze the coordinating and connecting role of relevant spatial elements and their configuration relationships between the natural environment and social culture, and identify the synergistic interaction relationship formed by the natural environment, social culture and the space of the ancient town.

[0063] S6.4: Based on the analytical results of steps S6.1 to S6.3, extract the mechanism by which the spatial element configuration relationship maintains stability and uniqueness under the influence of the canal transport system.

[0064] Furthermore, step S7 specifically involves: based on the characteristic that spatial genes are the product of long-term harmonious interaction between space, nature, and humanity, verifying and screening the configurational relationships of spatial elements, eliminating configurational relationships that have not formed a harmonious interaction between space, nature, and humanity, and retaining configurational relationships that can reflect the synergistic effect of the three and maintain the spatial stability and uniqueness of the ancient town, as the spatial genes of the Huaiyang Canal Ancient Town.

[0065] Beneficial effects: Compared with existing technologies, this invention introduces institutional operation mechanisms into the spatial analysis process of ancient towns along the Huaiyang Canal. Through systematic analysis of spatial elements, combinations of spatial elements, and their mechanisms of action, it can reveal the inherent logic of the formation of the spatial structure of the ancient town, effectively distinguishing between spatial genes with long-term stability and synergy and spatial phenomena formed in stages and sporadically. By introducing analytical steps for spatial element combination rules and reasons for combination, the subjectivity in the process of identifying spatial configuration relationships is reduced, and the repeatability and reliability of the method are improved, thus providing a more scientific and clear technical basis for the protection and renewal of ancient towns along the Huaiyang Canal. The method of this invention has a clear structure and well-defined steps, and is applicable to different types of ancient towns along the Huaiyang Canal, possessing good versatility and promotional value.

[0071] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0072] In this invention, unless otherwise stated, the following terms have the following meanings:

[0073] Spatial genes: Spatial genes refer to unique and relatively stable spatial combination patterns formed in the interaction between urban space and the natural environment and historical culture. They are both the product of the long-term interaction, coupling and evolution of urban space with the natural environment and historical culture, carrying information unique to different regions, forming the identity of urban characteristics, and playing a role in maintaining the harmonious relationship among the three.

[0074] Spatial elements: These refer to the basic units that constitute the spatial structure of an ancient town, including natural environmental elements and artificial environmental elements. Natural environmental elements include canals, water systems, and lakes, while artificial environmental elements include streets, bridges, wharves, buildings, and sluice gates.

[0075] Spatial element combination: refers to the organized combination relationship formed by multiple spatial elements in terms of spatial location, direction, connection mode and functional attributes.

[0076] The analysis dimensions of the canal transport system refer to the analytical framework used to analyze the impact of the canal transport system's operation mechanism on the spatial structure of ancient towns, including the orientation of storage and transportation functions, the driving force of commercial economy, the management of the canal transport system, and the integration of diverse cultures.

[0077] This paper takes an ancient town along the Huaiyang Canal as an example to illustrate the technical solution of the present invention in detail. To clearly explain the implementation process of this method, this embodiment selects two representative types of spatial element configuration relationships in the ancient town for in-depth analysis; as shown in the appendix... Figure 1 As shown in this embodiment, the spatial gene identification method for ancient towns along the Huaiyang Canal from the perspective of the canal transport system includes:

[0078] S1: Determine the penetrance of spatial genes in the ancient towns along the Huaiyang Canal, summarize the spatial characteristics of the ancient towns along the Huaiyang Canal, and screen the spatial characteristics based on stability and synergy.

[0079] S2: Determine the set of spatial elements corresponding to the selected spatial features, and select the set of spatial elements related to the canal transport system;

[0080] S3: Match each spatial element in the filtered spatial element set to the corresponding canal transport system analysis dimension;

[0081] S4: Based on the analysis dimension of the canal transport system, analyze the functional characteristics, morphological characteristics and distribution characteristics of spatial elements;

[0082] S5: Based on the analysis dimensions and spatial element analysis results, analyze the configurational relationships between spatial elements, including combination rules and combination reasons;

[0083] S6: Analyze the harmonious and interactive relationship between spatial elements and their configurations in the context of space, nature, and human elements;

[0084] S7: Eliminate spatial element configuration relationships in each spatial element set that do not conform to the harmonious interaction between space, nature, and humanity, and finally determine the spatial genes of the Huaiyang Canal Ancient Town.

[0085] Specifically, S1 above includes three steps: S1.1, S1.2, and S1.3.

[0086] S1.1 Based on existing relevant literature, historical data and field research analysis, the spatial genes of the ancient towns along the Huaiyang Canal were obtained, and the spatial characteristics of the ancient towns along the Huaiyang Canal were summarized.

[0087] The spatial characteristics data of the ancient towns along the Huaiyang Canal mainly come from local chronicles, historical records, academic research, and on-site surveys. The spatial characteristics of the ancient towns are summarized from aspects such as spatial pattern, functional organization, and transportation landscape.

[0088] Based on existing research and ancient map data, the spatial characteristics of the ancient town mainly include: boundaries along the canal, expansion along the river, fishbone pattern, alleys connecting to ancient post stations, ancestral halls and temples along the river, dikes along the river, and the Iron Rhinoceros suppressing the water.

[0089] S1.2. Based on the characteristic of long-term stable existence of spatial genes, and combining literature and historical images from different historical periods, the stability of the spatial features is screened, specifically including the following screening steps:

[0090] First, the historical continuity of the spatial pattern is examined, eliminating temporary spatial features that appeared only in a single historical period and failed to be maintained in subsequent periods. This aims to select a stable spatial framework that runs through the entire development of the ancient town. Second, the material sustainability of spatial elements is examined, eliminating combinations of elements whose functions have disappeared and whose material carriers no longer exist. This aims to select inheritable elements whose material spatial foundation has not undergone structural changes. Finally, the stability of the inheritance of spatial relationships is examined, eliminating features that existed but whose core spatial relationships have been broken due to modern construction. This aims to select core structural relationships whose spatial alignment has not been fundamentally changed.

[0091] Based on the above stability screening, the riverside strip layout and fishbone-shaped street network of the ancient town have continued from the Ming and Qing dynasties to the present day, and the spatial relationship between the core wharf and the streets and alleys has remained stable, thus passing the screening; however, some ancestral halls and ancient post stations no longer exist and failed the stability screening.

[0092] S1.3. Based on the characteristics of spatial genes reflecting the synergistic interaction of space, nature, and humanity, the synergy of spatial features that have passed the stability screening is tested, specifically including the following screening steps:

[0093] First, the adaptation relationship between spatial features and the natural environment is examined, eliminating spatial features that lack intrinsic connection with the canal system and are merely randomly distributed. This aims to select spatial element combinations that truly embody the symbiotic relationship between humans and water. Second, the functional connection between spatial features and the canal transport system is examined, eliminating spatial features that, although distributed along the river, have no direct functional connection with the transportation of canal goods and commercial activities. This aims to select core spatial elements driven by the canal transport system. Finally, the continuity relationship between spatial features and human activities is examined, eliminating spatial features whose functions have been broken and cannot interact and be passed on to modern life. This aims to select spatial genes with living heritage value.

[0094] Upon examination, the spatial pattern of the ancient town extending along the river reflects the town's adaptation to the water system. The connection between the streets and alleys and the wharf serves the needs of transporting goods by canal. Even after the transformation of the wharf's function, it still maintains interaction with residents' lives and cultural and tourism activities. These characteristics meet the requirements of the synergistic interaction between space, nature, and culture.

[0095] For this embodiment, the selected spatial features are: bounded by waterways, extending along the river, parallel river and street, juxtaposition of water and land, fishbone pattern, alleys connecting to water stations, government offices in the center, shops along the street, ancestral temples along the river, dikes along the river, and iron rhinoceros suppressing water. Among them, this embodiment will focus on analyzing the spatial features of "bounded by waterways, extending along the river, fishbone pattern, and alleys connecting to water stations".

[0096] The above S2 includes two steps: S2.1 and S2.2.

[0097] S2.1, Spatial Element Mining – By reviewing relevant literature, historical maps, and conducting on-site surveys, specific spatial elements constituting each selected spatial feature are extracted and identified as a set of spatial elements. , The number of spatial features, For the first A collection of spatial elements with spatial characteristics. For the ancient town of Huaiyang Canal as the research object, the natural environmental elements mainly include the canal and lakes, while the artificial environmental elements include streets and alleys, bridges, wharves, buildings, sluice gates, water storage facilities, post stations, river embankments, shops, government offices, customs houses, guild halls, academies, gardens and courtyards, ancestral halls and iron rhinoceroses.

[0098] S2.2 Screening of Canal Transport-Related Elements—Based on the operational mechanism of the canal transport system, determine whether the existence of each spatial element in the set of spatial elements is functionally related to the canal transport system. The criteria for this determination include:

[0099] Functional relevance determination, specifically, determines whether the spatial elements correspond to the storage and transportation link, trade link, management link, or cultural link in the operation mechanism of the canal transport system;

[0100] Documentary verification involves determining whether the appearance, scale, or distribution of the aforementioned spatial elements are recorded in local chronicles, canal transport archives, or historical maps in relation to the canal transport system.

[0101] Spatial location determination specifically involves determining whether the spatial element is adjacent to or connected to a canal, wharf, or storage node in terms of spatial location.

[0102] When a spatial element satisfies at least two of the following criteria—functional relevance, documentary corroboration, and spatial location—it is determined that the spatial element is related to the operational mechanism of the Grand Canal system.

[0103] In this embodiment, the spatial elements related to the canal transport system mainly include canals, wharves, streets, etc. The selection process in this embodiment is as follows: Figure 2 As shown.

[0104] The above S3 includes two steps: S3.1 and S3.2.

[0105] S3.1 Establishing Analytical Dimensions of the Grand Canal System—Based on the operational mechanism of the Grand Canal system, four analytical dimensions for spatial element analysis are constructed. Specifically, according to the basic process and derived functions of grain transport, the Grand Canal system is decomposed into four dimensions: storage and transportation function orientation, commercial and economic drive, river and canal system management, and integration of diverse cultures.

[0106] The operational mechanism of the canal transport system includes: storage and transportation, commerce, management, and culture.

[0107] The storage and transportation link is used to reflect the material storage, transfer and dispatch functions of the water storage, dam, wharf and post station along the route;

[0108] The commercial and trade links are used to reflect the trade activities of shops and streets around the dock;

[0109] The management process is used to reflect the administrative supervision functions of the government offices and customs offices.

[0110] The cultural elements are used to reflect the functions of communication and cultural identity among the people associated with the guild halls, academies, gardens, ancestral halls, and iron rhinoceroses.

[0111] Based on the aforementioned storage and transportation, trade, management, and cultural aspects, four analytical dimensions are constructed: storage and transportation function orientation, trade and economic drive, river and canal system management, and integration of diverse cultures.

[0112] S3.2 Matching Spatial Elements to Corresponding Dimensions—Based on the functional positioning of spatial elements, they are placed into the corresponding dimensions of the canal transport system analysis. Specifically, the spatial elements corresponding to the storage and transportation function include canals, water warehouses, wharves, post stations, sluice gates, and river embankments, with the corresponding combination of spatial elements serving the storage and transportation of goods; the spatial elements corresponding to the commercial economy drive include canals, wharves, shops, streets, and post stations, with the corresponding combination of spatial elements serving trade activities; the spatial elements corresponding to the canal transport system management include canals, government offices, wharves, and customs offices, with the corresponding combination of spatial elements serving administration and supervision; and the spatial elements corresponding to the integration of diverse cultures include guild halls, academies, gardens, ancestral temples, and iron rhinoceroses, with the corresponding combination of spatial elements serving the connection, communication, and cultural identity of different groups of people.

[0113] In this embodiment, the canal and ancient town elements involved in "bounded by the canal and expanded along the river" mainly match the dimension of storage and transportation function orientation; the street, wharf, and canal elements involved in "fishbone pattern, alleyways connecting water stations" mainly match the two dimensions of storage and transportation function orientation and commercial and economic drive. The correspondence between the spatial elements and the analysis dimensions of the canal transport system in this embodiment is as follows: Figure 3 As shown.

[0114] S4.1 Functional Characteristic Analysis – Clarifying how spatial elements emerged due to the needs of the Grand Canal and their core functions. Specifically, analyzing the roles of spatial elements in grain transport, material distribution, and commercial activities. In this embodiment, the ancient town settlement accommodates the activities of people involved in the Grand Canal transport, and its site selection serves the operation of the Grand Canal; the canal system serves as a transport route and water conservancy regulation function; streets and alleys facilitate the transport and distribution of materials from the wharf to the interior of the ancient town; and the wharf connects water and land transportation, serving as a key node for the transfer of Grand Canal transport materials.

[0115] S4.2 Morphological Feature Analysis – This section clarifies the specific physical form, scale, and spatial structure of spatial elements formed due to the needs of canal transport. Specifically, it analyzes the geometric form, scale, and construction methods of spatial elements. In this embodiment, the ancient town unfolds along the canal in a strip shape, with a length-to-width ratio of approximately 1:4; the main canal channel is 20-37 meters wide and extends linearly; the streets and alleys are fishbone-shaped, with the main street being wider and the alleys narrower; the wharf is constructed with multiple layers of stone steps, forming four levels of elevation, and is connected to the streets using an underpass structure.

[0116] S4.3 Distribution Characteristics Analysis – This section clarifies the specific locations, distribution patterns, and clustering levels of spatial elements formed due to the needs of canal transport. Specifically, it analyzes the location selection of spatial elements, their mutual distances, and their correspondence with related elements. In this embodiment, the ancient town extends along the canal, with North Street and South Street as its central axes, and the alleys leading to the wharves. The wharves are evenly distributed along the eastern bank of the canal, spaced approximately 90 meters apart, corresponding one-to-one with the alleys.

[0117] The above S5 includes two steps: S5.1 and S5.2.

[0118] S5.1 Identify spatial element combination rules—Based on the spatial location, directional relationship, connectivity, and adjacency relationship of spatial elements, identify the combination rules formed between elements.

[0119] In this embodiment, "bounded by the canal and expanding along the river" involves two spatial elements: the canal and the ancient town. The combination rules between the two are as follows: the spatial expansion axis of the ancient town is parallel to the direction of the canal, and the boundary of the ancient town is adjacent to the boundary of the canal. "Fishbone pattern and alleyways connecting to the water station" involves three spatial elements: streets and alleys, wharves, and the canal. The combination rules include: the main street and the secondary street form a primary-secondary relationship, forming a fishbone-shaped street and alley pattern; the alleyways and the wharves form a connection, directly leading to the water; the canal, the wharves, and the streets and alleys form a canal-wharf-street and alley sequence, and the alleyways and the wharves are connected by an underpass structure.

[0120] S5.2 Analyze the reasons for the combination of spatial elements—Based on the identification of combination rules, and combined with the analysis dimension of the canal transport system matched with the spatial elements, analyze the reasons for the combination of spatial elements to form the combination rules.

[0121] In this embodiment, "bounded by the canal and expanding along the river" matches the storage and transportation function orientation dimension. The reason for this combination is that the requirements of the canal system for the efficiency of material transportation drive the formation of close spatial connections between towns along the canal to meet the functional needs of material circulation and personnel distribution. "Fishbone pattern and alleyways connecting waterways" matches the storage and transportation function orientation and the commercial economy driving dimension. The reason for this combination is that the differentiation of primary and secondary streets and alleys stems from the demand for optimized spatial efficiency in commercial activities; the underpass structure achieves separation of people and goods through vertical elevation differences, improving transshipment efficiency; and the sequential relationship of canal-wharf-street and alleyway is determined by the complete process of canal transport materials: "water transport-transshipment-land transport-distribution".

[0122] For this embodiment, the spatial element analysis results are as follows: Figure 4 As shown.

[0123] The above S6 includes four steps: S6.1, S6.2, S6.3, and S6.4.

[0124] S6.1 Analysis of the Interaction between Natural Environment and Ancient Town Space – Based on the operational logic of the Grand Canal system, this paper analyzes the constraints and guidance of the natural environment on the space of the ancient town, as well as the adaptive response of the space of the ancient town to the natural environment.

[0125] In this embodiment, the flow direction and shape of the canal system determine the overall spatial form of the ancient town, serving as a natural boundary to guide the town's extension along the water, forming a pattern of "bounded by the canal and expanding along the river." The ancient town adapts to the natural environment through engineering measures such as wharves. The stone-stepped wharves connect the water surface and alley entrances in a multi-layered manner, forming a coordinated water-land spatial relationship.

[0126] S6.2 Analysis of the Interaction between Natural Environment and Socio-Humanistic Activities—Analyzing the supporting role of the natural environment on human activities, and the human activities' cognition and response to the natural environment. In this embodiment, the canal system provides transportation conditions for grain transport and commerce, promotes the commercial prosperity of the ancient town, and gives rise to the "fishbone pattern" street and alley organization and the "alley-to-water station" transshipment system.

[0127] S6.3 Analysis of the Interaction between Socio-cultural Factors and Ancient Town Space—Analyzing the shaping effect of socio-cultural factors on the spatial form of ancient towns, and the role of ancient town space in carrying and expressing social activities. In this embodiment, the economic demands driven by the canal system shaped the efficient transit street pattern, and the differentiation between primary and secondary streets stemmed from the optimization of spatial efficiency by commercial activities; the connection between wharves and alleyways served the needs of the material distribution process.

[0128] S6.4 Extracting the Mechanism of Spatial Gene Action—Based on the above analysis of interactive relationships, the intrinsic mechanism of spatial gene formation and evolution under the influence of the canal transport system is extracted. In this embodiment, the mechanism of spatial gene action under the influence of the canal transport system is as follows: based on the natural conditions of the canal and driven by the functional needs of canal transport, a spatial form of ancient towns adapted to water and land transportation is formed through specific combinations and configurations of spatial elements, and the synergistic interaction between space, nature, and culture is maintained in the long-term evolution.

[0129] S7. Based on the characteristic that spatial genes are the product of long-term harmonious interaction between space, nature, and humanity, the spatial element configuration relationships obtained from step S6 are verified. The specific judgment criteria are as follows: the adaptability of space to the natural environment, the carrying capacity of space for human activities, and the interaction between nature and humanity through spatial media.

[0130] In this embodiment, the concept of "bounded by the canal and expanding along the river" reflects the adaptability of the ancient town's space to the natural conditions of the canal system, while also accommodating the needs of personnel flow and material distribution under the canal transport system, thus meeting the requirements of collaborative evolution. The "fishbone pattern, alleyways connecting waterways" adapts the connectivity between streets and wharves to the natural conditions of the canal shoreline, serving the efficient transfer of canal transport materials. The differentiation between primary and secondary streets reflects the shaping of spatial organization by economic activities, also meeting the requirements of collaborative evolution.

[0131] After screening, the spatial genes finally determined in this embodiment are: "bounded by the canal and expanded along the river" - reflecting the parallel and adjacent relationship between the ancient town and the canal under the canal transport system; "fishbone pattern and alleyway connecting water stations" - reflecting the combination of streets and wharves for the efficient transfer of canal transport materials.

[0132] For this embodiment, the final analysis result of the spatial gene "bounded by transportation and expanded along the river" is as follows: Figure 5 As shown.
