Description

Technical Field

[0001] The present invention relates to the technical field of ecosystem service assessment, and in particular to a method for quantitatively assessing the supply and demand of ecosystem cultural services from a dynamic perspective. Background Art

[0002] Cultural Ecosystem Services (CES) provide humans with multiple values, including aesthetics, entertainment, social connections, education, inspiration, and a sense of place. However, their intangible and subjective nature leads to the following limitations in traditional quantitative assessment methods: (1) Existing methods mostly evaluate CES statically from a spatial dimension, ignoring temporal dynamics (such as supply and demand fluctuations at different times of the day); (2) The units of supply and demand indicators are not unified, making direct matching difficult, resulting in inaccurate evaluation results; (3) The inability to accurately identify periods and areas of supply and demand contradictions restricts the sustainable management of cultural services in urban ecosystems.

[0003] Therefore, there is an urgent need for a quantitative assessment method for the supply and demand of ecosystem cultural services from a dynamic perspective. Summary of the Invention

[0004] In response to the above-mentioned deficiencies in the prior art, the present invention provides a method for quantitatively evaluating the supply and demand of ecosystem cultural services from a dynamic perspective.

[0005] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is: A quantitative assessment method for the supply and demand of ecosystem cultural services from a dynamic perspective includes the following steps: The assessment area is divided into multiple spatial units, and the opening time and area data of different ecosystem cultural service types in each spatial unit are obtained; Based on behavioral observation and public participation in GIS mapping, the number of tourists and the length of stay of tourists in each spatial unit for different ecosystem cultural service types were obtained; Based on the opening hours, area data, number of visitors, and length of stay of visitors of different ecosystem cultural service types in each spatial unit, the supply and demand of different ecosystem cultural service types in each spatial unit were quantified in hours. The supply and demand ratio of different ecosystem cultural service types in each spatial unit is calculated based on the quantitative supply and demand results to obtain the supply and demand relationship of ecosystem cultural services in the assessment area.

[0006] Furthermore, ecosystem cultural service types include aesthetic services, leisure services, social relationship services, educational services, knowledge system services, inspiration services, and sense of place services.

[0007] Furthermore, based on the opening hours, area data, number of visitors, and length of stay of visitors of different ecosystem cultural service types in each spatial unit, the supply and demand of different ecosystem cultural service types in each spatial unit were quantified in hourly units, including the following steps: A1. Based on the area data of different ecosystem cultural service types in each spatial unit, calculate the tourist capacity of different ecosystem cultural service types in each spatial unit; A2. Based on the opening hours, visitor capacity, number of visitors, and visitor length of stay of different ecosystem cultural service types in each spatial unit, calculate the supply and demand of different ecosystem cultural service types in each spatial unit in hours, so as to quantify the supply and demand of different ecosystem cultural service types in each spatial unit.

[0008] Furthermore, in step A1, based on the area data of different ecosystem cultural service types in each spatial unit, the tourist capacity of different ecosystem cultural service types in each spatial unit is calculated, which is expressed as:

[0009] in: For the space unit Tourist capacity of each ecosystem cultural service type, For ecosystem cultural service type labels, For the space unit The area of ​​each ecosystem cultural service type, For the space unit Per capita emergency shelter area for each ecosystem cultural service type.

[0010] Furthermore, in step A2, based on the opening hours, visitor capacity, number of visitors and visitor length of stay of different ecosystem cultural service types in each spatial unit, the supply and demand of different ecosystem cultural service types in each spatial unit are calculated respectively with hours as the time unit. The specific process is: based on the opening hours and visitor capacity of different ecosystem cultural service types in each spatial unit, the supply of different ecosystem cultural service types in each spatial unit is calculated with hours as the time unit, and based on the number of visitors and visitor length of stay of different ecosystem cultural service types in each spatial unit, the demand of different ecosystem cultural service types in each spatial unit is calculated with hours as the time unit.

[0011] Furthermore, based on the opening hours and visitor capacity of different ecosystem cultural service types in each spatial unit, the supply of different ecosystem cultural service types in each spatial unit is calculated with hours as the time unit, expressed as:

[0012] in: For the space unit The supply of various ecosystem cultural services, For ecosystem cultural service type labels, For the space unit The opening hours of the ecosystem cultural service types, For the space unit The capacity of different ecosystem cultural service types.

[0013] Furthermore, based on the number of tourists and the length of stay of tourists for different ecosystem cultural service types in each spatial unit, the demand for different ecosystem cultural service types in each spatial unit is calculated with hours as the time unit, and is expressed as:

[0014] in: For the space unit The demand for the cultural services of the ecosystem For ecosystem cultural service type labels, For the space unit The average length of stay of tourists for each ecosystem cultural service type, The space unit The number of tourists visiting each ecosystem cultural service type within a set assessment period.

[0015] Furthermore, the supply-demand ratio of different ecosystem cultural service types in each spatial unit is calculated based on the quantitative results of supply and demand, which is expressed as:

[0016] in: For the space unit The supply-demand ratio of the ecosystem cultural service types, For ecosystem cultural service type labels, For the space unit The demand for the cultural services of the ecosystem For the space unit The supply of various ecosystem cultural services.

[0017] The present invention has the following beneficial effects: The present invention divides the assessment area into multiple spatial units, obtains the opening hours and area data of different ecosystem cultural service types in each spatial unit, and then obtains the number of tourists and the length of stay of tourists of different ecosystem cultural service types in each spatial unit based on behavioral observation and public participation in GIS mapping. Then, based on the opening hours, area data, number of tourists and length of stay of tourists of different ecosystem cultural service types in each spatial unit, the supply and demand of different ecosystem cultural service types in each spatial unit are quantified with hours as the time unit to calculate the supply and demand ratio of different ecosystem cultural service types in each spatial unit. Finally, according to the supply and demand ratio of different ecosystem cultural service types in each spatial unit, the quantitative assessment results of the supply and demand of ecosystem cultural services in the assessment area are obtained. The whole method process breaks through the limitations of traditional static assessment, and can accurately identify the time periods and areas of contradictions between supply and demand of ecosystem cultural services, thereby improving the sustainable management level of urban ecosystem cultural services.
