[0035] Furthermore, the process of constructing the border landscape basic information database includes:

[0036] Divide the basic data of the border landscape based on data types to obtain basic current geographical information data, thematic data on border landscape features, and thematic data on the history and culture of border towns; construct corresponding sub-databases for the divided thematic data; construct a metadata database as an affiliated database, and the database stores the data content, data quality, data status, and data characteristic information of each sub-database; organize and integrate each sub-database and the affiliated database according to spatial topology and network relationships to obtain the basic information database of the border landscape.

[0037] Specifically, the sub-database corresponding to the basic current geographical information data includes digital orthophoto image data, digital elevation model data, and vector digital zoning data; the sub-database corresponding to the thematic data on border landscape features includes raster images, vector data, explanatory texts, 3D models, online comments, and literature data; the sub-database corresponding to the thematic data on the history and culture of border towns includes local chronicles data, visit and research records, historical image photos, and folk stories.

[0039] Among them, obtain the border town landscape features, and obtain the database level division based on the border town landscape features and the landscape carrier types; construct the border town landscape feature thematic database based on the database level division.

[0040] Specifically, the first layer of the border town landscape feature thematic database divides the border town landscape features into four categories, corresponding to the basic data of border towns, the spatial data of border towns, the architectural style data of border towns, and the historical and cultural data of border towns respectively; the second layer locates and organizes the four types of data according to the town zoning; the third layer classifies and labels the spatial distribution of the landscape feature carriers within the town zoning according to their different physical attributes.

[0041] Taking the construction of the basic information database of the border landscape in Heilongjiang Province (hereinafter referred to as the border landscape) as an example, the implementation process of the method for constructing the border landscape database based on the identification of characteristic elements is described as follows:

[0042] First, it must be based on the recognition and classification of the elements of the border landscape. The World Heritage Centre of UNESCO classifies world landscapes into three categories in the Operational Guidelines for the Implementation of the World Heritage Convention: natural landscapes, cultural landscapes, and natural and cultural landscapes. The natural landscapes in the border landscape include geographical features and ecological environments, the cultural landscapes include landmark landscapes, historical sites, multiculturalism, and ethnic stories, while the natural and cultural landscapes include urban historical landscapes, settlement agricultural landscapes, and border defense landscapes, etc., as Figure 1 shown. The border natural landscape refers to the natural features and ecological environment in the border areas of a country. Due to the special geographical location, border areas often span multiple natural geographical regions and have a rich variety of ecosystem types, which are an important part of a country's natural heritage; border areas are usually the intersection points between different cultures, ethnic groups, and countries. Over a long period, these areas have shown cultural diversity after experiencing complex cultural exchanges and integration processes, presenting rich and diverse cultural elements and landscape types. For example, the architectural styles, religious beliefs, customs, and folk arts in border areas; the border natural and cultural landscape is another landscape type derived from the long-term integration of diverse natural environments and multiculturalism, represented by ethnic settlements and their surrounding environments, reflecting the harmonious coexistence between humans and nature.

[0043] The basic information database of the border landscape is established based on the research results of the landscape features of border towns in Heilongjiang Province in the past three years using the ARCGIS geographic information system. This example collects data, decouples information, and builds a system for the geographical distribution data, element mapping information, and historical information of border towns on the basis of the project of the "Construction Plan for the Characteristic Landscape of Border Cities in Heilongjiang Province", so as to construct a digital border information system. The database contains relevant content such as the spatio-temporal distribution, historical evolution, ecological environment, and social and cultural data of each entity element in border towns.

[0044] Main Contents of the Border Landscape Database

[0045] In the process of the formation and continuous development of the border landscape, a series of ecological environment factors such as the atmospheric environment and hydrological environment affect the continuous change of the topography and landforms. In addition, non-material factors such as relevant historical evolution, the spread and integration of multiculturalism, and social and cultural changes are also the core forces that give rise to the diversity of the border landscape.

[0046] Therefore, the main contents of the border landscape database can be divided into six major parts: geospatial data, ecological environment data, material spatial data, non-material spatial data, social and cultural data, and picture and video data. Find data sources according to data requirements, classify and integrate the corresponding data, and the detailed data content and requirements are shown in Table 1.

[0048]

[0049]

[0050] Overall Composition of the Frontier Landscape Database

[0051] The three-dimensional spatial database is a systematic whole. The content it contains has common spatio-temporal and cultural expression characteristics. Each part of the content is organized into feature classes or multi-layer sets to form sub-databases. The sub-databases are organized according to spatial topology and network relationships to establish the overall database. Based on the basic requirements of the database research content and framework construction technology, the basic information database of the frontier landscape can be divided into 4 sub-databases. As Figure 2 shown, according to different data types, it is divided into basic current geographical information data, thematic data of frontier landscape features, and thematic data of frontier town historical culture for separate storage. At the same time, a metadata database is established.

[0052] The basic current geographical information database is used to store the latest remote sensing images and vector data of geographical information, including digital orthophoto map (DOM) data, digital elevation model (DEM) data, digital zoning (DLG) vector data, etc. within the entire territory of Heilongjiang Province. At the same time, environmental data such as atmosphere, hydrology, geology, and species diversity are stored.

[0053] The thematic database of frontier landscape features mainly consists of vector maps of 18 county-level administrative regions from Mohe County to Dongning City from north to south, various types of pictures, images, and online comments related to the frontier; the thematic database of frontier town historical culture has sorted out all data, written materials, vector and raster images, as well as a large number of three-dimensional models and images, etc. related to the 18 frontier town atlases and investigations, providing data support for the value assessment, protection, and utilization of the frontier landscape. Among them, the metadata database, as an affiliated database, is mainly used to record the content, quality, status, and other information describing data characteristics of various data, to facilitate database administrators to manage and use the data.

[0054] Data Sources of the Frontier Landscape Database

[0055] Based on the content and structure requirements of the frontier landscape database, sort out the data requirements and find the data sources. Through the investigation of the entity information of 18 frontier towns, the collection and collation of relevant materials, the required information is recorded in the database in the forms of text, data, two-dimensional pictures, three-dimensional images, three-dimensional models, etc. for storage and expression. According to the content requirements, the data sources of the frontier landscape database are mainly divided into the following several ways, as Figure 3 shown:

[0056] "Annals of Heilongjiang Province": A local chronicle compiled by the Local Chronicles Compilation Committee of Heilongjiang Province, which records the history and current situation of the development of land resources, land development, land property rights system, cadastral management, land use management, etc. in Heilongjiang Province, and is an important source of information for this research.

[0057] Local chronicles of 18 counties such as "Annals of Mohe County" and "Annals of Tahe County": Records of the history and current situation of the development of various aspects such as local nature, politics, economy, and culture compiled by each county-level compilation committee, and are the core sources of information for this research.

[0058] "Investigation Report on Resources of Frontier Towns in Heilongjiang Province": A data collection compiled by the research team based on the research results of frontier towns.

[0059] "Cultural and Tourism Development Plan for the 14th Five-Year Plan" of Heilongjiang Province: Issued by the Department of Culture and Tourism of Heilongjiang Province in 2021, and 8 out of 12 planning columns provide development planning guidance for the protection and development and utilization of frontier landscapes, and are important sources of information for this research.

[0060] GPS surveying and mapping data and various research images: Since 2021, the research team has conducted large-scale field surveys and on-site mapping of some areas of frontier towns, and collected a large amount of cloud data and aerial photography image data, providing a large amount of three-dimensional data information for the database. In addition, the research team has currently collected 14,782 pieces of image data such as historical images, real-scene pictures, and panoramic images of frontier town landscapes.

[0061] Contents of the Thematic Database of Landscape Features of Frontier Towns in Heilongjiang Province

[0062] As one of the core databases of the Information Database of Frontier Landscape Features in Heilongjiang Province, the structure construction and hierarchical design of the Thematic Database of Landscape Features of Frontier Towns should conform to the characteristics of the natural environment, spatial distribution, and multi-cultural integration in the frontier areas.

[0063] Thematic Data Structure

[0064] The landscape feature system of frontier towns includes complex and changeable natural geographical environment elements and multi-cultural elements derived from the long-term integration of multiple ethnic groups. The natural geographical environment elements give rise to unique landscape features such as "mountains", "waters", "forests", "fields", "lakes", "islands", etc. from the mountainous landforms formed by the Greater and Lesser Khingan mountain ranges and the Sanjiang Plain landforms formed by the confluence of the Heilongjiang, Songhua, and Wusuli rivers. The multi-cultural elements give rise to 23 "National Key Towns" represented by Aihui Town in Heihe City and Mingshan Town in Luobei County, 7 "Famous Towns with Special Landscape for Tourism", 4 "Characteristic Towns of China", 3 "Beautiful and Livable Towns", etc. cultural landscapes derived from the long-term coexistence of large mixed settlements and small concentrated settlements of 53 ethnic groups.

[0065] According to the compositional characteristics of the frontier landscape elements, the structure of the special database for the frontier town landscape is divided into 4 parts according to the town landscape objects, namely the basic data of frontier towns, the spatial data of frontier towns, the architectural style data of frontier towns, and the historical and cultural data of frontier towns, as Figure 4 shown. According to the own attributes of each part of the elements, it can be divided into many aspects such as geographical information, ecological environment, urban structure, social structure, historical information, surrounding environment, etc. The content of each part is strictly integrated and input according to its chronological and spatial development order.

[0066] Special data elements and layer structure

[0067] In order to better identify the frontier town landscape elements controlled by each geomorphic area, this study selects the regional core towns from Mohe City and Tahe County controlled by the Daxing'anling geomorphic area from west to east to construct the database elements, and selects 18 county central towns such as Xilingji Town, Tahe Town, Huma Town, Aihui Town, Luobei Town, etc. as the core elements. The database is hierarchically divided according to the composition of the special data elements of the frontier town landscape and the type of landscape carriers, so as to classify and summarize the natural landscape, cultural landscape, and natural and cultural landscape of the frontier town landscape and input the data. The data structure is as Figure 5 shown.

[0068] Element level 1: Classify the frontier town landscape elements into 4 categories, which respectively correspond to the basic data of frontier towns, the spatial data of frontier towns, the architectural style data of frontier towns, and the historical and cultural data of frontier towns. All categories cover all the landscape elements of the representative towns of 18 counties in the frontier.

[0069] Element level 2: Locate and sort out different landscape elements according to the administrative divisions of the representative towns of 18 counties.

[0070] Element level 3: Classify and label the spatial distribution of the landscape element carriers in different regions according to their different physical attributes. With the help of the ARCGIS geographic information system, different spatial data can be transformed and organized into a series of thematic layers, tables, models, etc., so as to edit, analyze and reuse them.

[0071] This embodiment discloses a computer device, including: a memory, a processor, and a computer program stored on the memory and executable on the processor. The processor executes the computer program to implement the steps of the above-mentioned method for constructing a frontier landscape database based on feature element recognition.

[0072] This embodiment discloses a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the steps of the above-mentioned method for constructing a frontier landscape database based on feature element recognition are implemented.

[0073] This embodiment discloses a computer program product, including a computer program which, when executed by a processor, implements the steps of the above-mentioned method for constructing a frontier landscape database based on feature element recognition.

[0074] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
