[0002] Urbanization manifests itself in many ways, primarily including population growth, economic development, expansion of construction land, and improved living standards. Economic prosperity is considered the fundamental foundation of urbanization, while sustained population growth and the expansion of urban construction land embody this trend. Continuous improvements in living standards are considered the ultimate goal. Previous studies have often focused solely on population, economy, and urban construction land. Urbanization levels are evaluated jointly by land, economy, population, and living standards, and the interactive responses of urbanization to ecosystem services should also be analyzed from these four perspectives. However, current research generally measures the overall level of urbanization using the first three (land, economy, and population), ignoring the factor of living standards.

DETAILED DESCRIPTION

[0021] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0022] Figure 1 The flowchart of an embodiment of an optimization method for comprehensive urbanization indicators provided by the present invention is shown. The optimization method for comprehensive urbanization indicators can be executed by electronic devices such as terminal devices or servers. The terminal device can be any fixed or mobile terminal such as user equipment (UE), mobile device, user terminal, terminal, cellular phone, cordless phone, personal digital assistant (PDA), handheld device, computing device, vehicle-mounted device, wearable device, etc. The server can be a single server or a server cluster composed of multiple servers. Any electronic device can implement the optimization method for comprehensive urbanization indicators by calling computer-readable instructions stored in a memory through a processor. Figure 1 As shown, the following steps are included: S1. Construct a living standard urbanization index for evaluating the comprehensive level of urbanization, and determine POI data corresponding to the POI categories required to construct the living standard urbanization index for the target area.

[0023] The living standard urbanization indicators include: convenient medical services, transportation facilities, convenient living services, and residents' savings levels. The target area can be any city, region, or other area, without any restrictions. The process of determining the POI data corresponding to the POI categories required to construct the living standard urbanization indicators for the target area specifically includes: selecting the POI categories required for constructing the living standard urbanization indicators based on the actual situation of the target area, and screening and cropping all POI data of the required POI categories within the target area.

[0024] It's important to note that the Urban Living Standards Index considers access to healthcare, transportation, economy, shopping, and leisure, encompassing nearly every aspect of daily life. POI categories include hospitals and clinics, public transportation and service stations, and shopping and service locations, with no restrictions.

[0025] S2. Constructing a spatial distribution map of living standards indicators for the target area based on the socioeconomic data of the target area and the POI data.

[0026] In S2, specifically: S21. Using a kernel density analysis method, convert the POI data into a kernel density analysis chart of the living standard urbanization index, and determine the grading weight of the kernel density analysis chart of the living standard urbanization index.

[0027] Among them, the kernel density analysis method is used in ArcGIS software to convert the vector POI data into a spatial grid map, and the heat space distribution map of the living standard urbanization indicators (medical convenience services, transportation facilities services, life convenience services and residents' savings level) is constructed. The heat space distribution map of various living standard urbanization indicators is reclassified and graded to obtain the kernel density analysis map of the living standard urbanization indicators (such as Figure 2 As shown, from left to right are the hierarchical weights of: transportation facilities services, life convenience services and medical convenience services).

[0028] S22. Based on the grading weights, the socioeconomic data are distributed to obtain a spatial distribution map of the living standard indicators of the target area.

[0029] Among them, based on the collected socioeconomic data of the target area, the data are allocated proportionally to the kernel density analysis map of urbanization indicators of living standards to obtain the spatial distribution map of living standards indicators of the target area.

[0030] It should be noted that the process of proportional allocation is as follows: first, kernel density analysis is performed on the POI data, and then the socioeconomic data are graded according to the corresponding density levels on the distribution map, and the living standard indicator spatial distribution map is prepared by allocating the socioeconomic data according to the graded levels to the kernel density analysis map of the urbanization indicators.

[0031] S3. Based on the spatial distribution map of living standard indicators, normalize the comprehensive urbanization level indicators of the target area, including the living standard urbanization indicators, to obtain optimized comprehensive urbanization level indicators of the target area.

[0032] The comprehensive urbanization level indicators include: economic urbanization indicators, land urbanization indicators, population urbanization indicators, and living standard urbanization indicators. The spatial distribution map of the living standard indicators was normalized in ArcGIS software and then fused using a raster calculator to form a complete comprehensive urbanization level indicator, i.e., the optimized comprehensive urbanization level indicator.

[0033] It should be noted that the default indicators for economic urbanization are GDP, the default indicators for land urbanization are the proportion of built-up land, and the default indicators for population urbanization are Points of Presence (POPs). These indicators can be set based on actual circumstances and are not restricted here. In addition to socioeconomic data and POI data, land use data and administrative division data for the target area can also be included.

[0034] like Figure 3 As shown in the figure, based on POI data and combined with socioeconomic data, land use data, and administrative division data, four new indicators of urban living standards have been added: convenient medical services, transportation facilities, convenient living services, and residents' savings levels. These four indicators jointly consider the convenience of medical care, transportation, economic, shopping, and leisure needs, covering many aspects of residents' daily lives. They have improved the construction of the urbanization development indicator system and provided an important theoretical basis for evaluating urbanization levels.

[0036] In an optional manner, the construction module 220 is specifically configured to: Using a kernel density analysis method, converting the POI data into a kernel density analysis chart of the living standard urbanization index, and determining the grading weight of the kernel density analysis chart of the living standard urbanization index; Based on the grading weights, the socioeconomic data are distributed to obtain a spatial distribution map of the living standard indicators of the target area.
