Description

Technical Field

[0001] The present invention relates to the technical field of land value calculation, and more specifically, to a land value calculation method and system based on GEP accounting. Background Art

[0002] With the deepening development of ecological civilization, people are increasingly aware that land not only has economic value but also carries important ecological and social value. The concept of ecosystem services has emerged, emphasizing the various benefits that natural ecosystems provide to humans, including provisioning services (such as food and water resources), regulating services (such as climate regulation and flood control), supporting services (such as soil formation and biodiversity maintenance), and cultural services (such as leisure and aesthetic experience). The Green Economy Policy (GEP), a new approach to measuring the value of ecosystem services, provides a new perspective and tool for the comprehensive assessment of land value.

[0003] However, current land valuation methods based on GEP accounting are still imperfect, with problems such as inconsistent accounting standards, irregular accounting cycles, and a lack of in-depth analysis and comparison of accounting results. This not only limits the scope of application of GEP accounting methods in land resource management, but also affects the accuracy and scientific nature of land value assessments.

[0004] Therefore, it is crucial to develop a land value calculation method and system that can regularly and systematically perform GEP accounting and conduct in-depth correlation and comparative analysis of the results. This method and system should comprehensively consider the land's material product output, regulatory services, and cultural services, dynamically reflecting changes in land value and providing a scientific basis for long-term land resource planning. Furthermore, this method and system must be broadly applicable, meeting the management needs of various land types, including agricultural, forestry, and tourism land, to promote the rational use and sustainable development of land resources.

[0005] Based on the above background, the present invention proposes a land value calculation method and system based on GEP accounting, which aims to comprehensively and accurately evaluate land value through scientific and systematic accounting and analysis, and provide strong support for land resource management. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a land value calculation method and system based on GEP accounting.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A land value calculation system based on GEP accounting, including a GEP accounting module, an accounting comparison module, and a land value hierarchy module;

[0009] The GEP accounting module periodically obtains the GEP accounting value of the land;

[0010] The calculation and comparison module: each time a GEP calculation value is obtained, the calculation comparison value Vz corresponding to the period is obtained synchronously;

[0011] The land value hierarchy module obtains a land value hierarchy value Syk based on the GEP accounting value and the accounting comparison value Vz of the land, and determines the value hierarchy of the land based on the land value hierarchy value.

[0012] Furthermore, the GEP accounting value of the land is obtained periodically, specifically: the material product output Bt(A), regulatory service function Bt(B) and cultural service function Bt(C) of the land in one cycle are collected, and the GEP accounting value of the land simulation model is obtained using the formula GEP=Bt(A)*A1+Bt(B)*A2+Bt(C)*A3, where A1 is the material product output coefficient, A2 is the regulatory service function coefficient, and A3 is the cultural service function coefficient.

[0013] Furthermore, the process of obtaining the accounting comparison value is as follows: obtain the GEP accounting value of p periods before the current time of the system, construct a rectangular coordinate system with the period as the X-axis and the GEP accounting value as the Y-axis, obtain the accounting cycle curve, and then obtain the stage accounting value Ke(DP) and the start and end stability value, calculate the difference between the stage accounting value and the start and end stability value to obtain the accounting gap value, when the accounting gap value is greater than 0, mark the accounting gap value as the accounting positive change value Be(DP), when the accounting gap value is ≤0, do not do the next step, obtain the average accounting swing value YB(DP), and use the formula The calculated comparison value Vz is obtained, where DP1 is the first coefficient, DP2 is the second coefficient, the value of DP1 is 1.15, and the value of DP2 is 1.32.

[0014] Furthermore, the calculation cycle curve is obtained in the following manner: the GEP calculation value of each cycle is marked as a calculation point in the rectangular coordinate system in the form of a point, and two calculation points of adjacent cycles in the rectangular coordinate system are connected to obtain the calculation cycle curve.

[0015] Furthermore, the stage accounting value is obtained according to the following method: draw perpendicular lines from the two end points of the accounting cycle curve to the X-axis to obtain two calculation start and end perpendicular lines, and form a closed figure by the accounting cycle curve, the two calculation start and end perpendicular lines and the X-axis. The total area of ​​the closed figure is marked as the stage accounting value and marked as Ke(DP).

[0016] Furthermore, the start and end stability values ​​are obtained in the following manner: the two endpoints of the calculation period curve in the rectangular coordinate system are connected to obtain the calculation start and end lines, and the calculation start and end lines, the two calculation start and end perpendicular lines and the X-axis form a closed figure, and the total area of ​​the closed figure is marked as the start and end stability values.

[0017] Furthermore, the average accounting swing value YB (DP) is obtained according to the following method: all GEP accounting values ​​are sorted in order according to the order of the cycles, the difference between the two adjacent GEP accounting values ​​after sorting is calculated and the absolute value is taken to obtain the accounting swing value, all the accounting swing values ​​are summed up and the average is taken to obtain the average accounting swing value YB (DP).

[0018] Furthermore, the formula Syk=GEP*hst+Vz*hsb is used to obtain the land value level value Syk, where hst is the accounting coefficient and hsb is the comparison coefficient. The value of hst is 0.51 and the value of hsb is 0.28.

[0019] Furthermore, the value level of the land is determined in the following manner: obtaining the land value level value Syk, the range of each land value level value Syk corresponds to a value level, the range of the land value level value Syk is [0, Sy1], (Sy1, Sy2], …, (Syk-1, Syk], the value level includes value level 1, value level 2, …, value level k-1, value level k, wherein the land value of value level 1 is less than the land value of value level 2, …, less than the land value of value level k.

[0020] Furthermore, a land value calculation method based on GEP accounting includes the following steps:

[0021] S1: Periodically obtain the GEP accounting value of the land and simultaneously obtain the corresponding accounting comparison value for each period;

[0022] S2: Obtain the land value level value based on the GEP accounting value of the land and the accounting comparison value Vz;

[0026] Figure 1 This is a flow chart of a land value calculation method based on GEP accounting;

[0027] Figure 2 This is a system module diagram of a land value calculation system based on GEP accounting. DETAILED DESCRIPTION

[0028] Example 1: Reference Figure 1 A land value calculation method based on GEP accounting includes the following steps:

[0029] S1: Periodically obtain the GEP accounting value of the land and simultaneously obtain the corresponding accounting comparison value for each period.

[0030] S2: Obtain the land value level value based on the GEP accounting value of the land and the accounting comparison value Vz.

[0031] S3: Determine the value hierarchy of the land based on the land value hierarchy value.

[0032] Example 2: Reference Figure 2 , a land value calculation system based on GEP accounting, including a GEP accounting module, an accounting comparison module, and a land value hierarchy module.

[0033] GEP accounting module: periodically obtains the GEP accounting value of land.

[0034] The GEP accounting value of the land is obtained periodically, specifically: the material product output Bt(A), regulatory service function Bt(B) and cultural service function Bt(C) of the land in one cycle are collected, and the GEP accounting value of the land simulation model is obtained using the formula GEP=Bt(A)*A1+Bt(B)*A2+Bt(C)*A3, where A1 is the material product output coefficient, A2 is the regulatory service function coefficient, and A3 is the cultural service function coefficient;

[0035] Example: The land's material product output is obtained as follows: Agricultural products: 6,000 tons of wheat, 5,000 tons of corn, 4,000 tons of rice. Forest products: 5,000 cubic meters of timber (converted to tons based on density), 1,000 tons of fruit. Aquatic products: 1,000 tons of fish, 500 tons of shellfish. Total material product output = 6,000 + 5,000 + 4,000 + 5,000 + 1,000 + 1,000 + 500 = 22,500 tons.

[0036] The regulating services of land are derived as follows: Carbon sequestration: 50 tons of carbon / hectare, carbon price 100 yuan / ton, carbon sequestration value = 50 × 100 = 5,000 yuan / hectare. Oxygen release: 133.5 tons of oxygen / hectare, oxygen price 10 yuan / ton, oxygen release value = 133.5 × 10 = 1,335 yuan / hectare. Water conservation: 100 mm / hectare, water price 1 yuan / cubic meter, water conservation value = 100 × 10 = 1,000 yuan / hectare. Soil conservation: 50 tons / hectare, soil conservation value 50 yuan / ton, soil conservation value = 50 × 50 = 2,500 yuan / hectare. The regulating services of land = 5,000 + 1,335 + 1,000 + 2,500 = 9,835 yuan / hectare.

[0037] The cultural service functions of land include leisure and tourism functions, cultural heritage functions, aesthetic value functions, etc. The leisure and tourism function refers to the ability of land to provide people with sightseeing, recreation, entertainment and other services.

[0038] Commonly used methods for calculating the quantity of leisure tourism functions include: the number of tourists method.

[0039] Methods: The leisure tourism function was evaluated by counting the number of tourists.

[0040] Formula: Leisure tourism function = number of tourists × unit tourist value

[0041] The number of tourists can be obtained through scenic spot statistics or questionnaire surveys. The value per tourist can be estimated based on tourism revenue or tourist spending data.

[0042] Example: A certain area has 100,000 tourists per year, with a unit tourist value of 500 yuan. The leisure tourism function value = 100,000 × 500 = 50 million yuan.

[0043] Cultural inheritance function

[0044] The cultural heritage function refers to the role of land in protecting cultural heritage and passing on traditional knowledge. Common calculation methods include: cultural heritage value assessment.

[0045] Methods: The cultural heritage function was evaluated by the number and protection level of cultural heritage.

[0046] formula:

[0047] The value of cultural heritage can be estimated through expert appraisal, market value or replacement cost method.

[0048] There are 5 cultural heritage sites on a certain land, each valued at 1 million yuan, 2 million yuan, 3 million yuan, 4 million yuan and 5 million yuan respectively.

[0049] Cultural heritage function = 100+200+300+400+500=15 million yuan.

[0050] The cultural service function of the land is achieved through the following means: Leisure and tourism function: 50 million yuan. Cultural heritage function: 15 million yuan. Aesthetic value function: 5 million yuan. Comprehensive cultural service function = 5000 + 1500 + 500 = 70 million yuan.

[0051] Calculation and comparison module: Every time a GEP calculation value is obtained, the calculation comparison value Vz corresponding to the period is obtained synchronously.

[0052] The process of obtaining the calculation comparison value is as follows: obtain the GEP calculation value of p periods before the current time of the system, construct a rectangular coordinate system with the period as the X-axis and the GEP calculation value as the Y-axis, mark the GEP calculation value of each period in the rectangular coordinate system as a calculation point in the form of a point, connect the two calculation points of adjacent periods in the rectangular coordinate system, and then obtain the calculation cycle curve, draw perpendicular lines from the two end points of the calculation cycle curve to the X-axis to obtain two calculation start and end perpendicular lines, and form a closed figure with the calculation cycle curve, the two calculation start and end perpendicular lines and the X-axis. The total area of ​​the closed figure is marked as the stage calculation value and marked as Ke(DP), and the two end points of the calculation cycle curve in the rectangular coordinate system are connected. The calculation start and end lines are obtained, and a closed figure is formed by the calculation start and end lines, the two vertical lines and the X-axis. The total area of ​​the closed figure is marked as the start and end stable values. The stage calculation value and the start and end stable values ​​are differenced to obtain the calculation gap value. When the calculation gap value is greater than 0, the calculation gap value is marked as the calculation positive change value Be(DP). When the calculation gap value is less than or equal to 0, no further processing is performed. All GEP calculation values ​​are sorted in the order of the cycles. The difference between the two adjacent GEP calculation values ​​after sorting is calculated and the absolute value is taken to obtain the calculation swing value. All the accounting swing values ​​are summed and averaged to obtain the average accounting swing value YB(DP). Using the formula The calculated comparison value Vz is obtained, where DP1 is the first coefficient, DP2 is the second coefficient, the value of DP1 is 1.15, and the value of DP2 is 1.32.

[0053] Land value hierarchy module: Use the formula Syk=GEP*hst+Vz*hsb to obtain the land value hierarchy value Syk, where hst is the accounting coefficient and hsb is the comparison coefficient. The value of hst is 0.51 and the value of hsb is 0.28. The value hierarchy of the land is determined based on the land value hierarchy value.

[0054] The value level of land is determined in the following way: obtain the land value level value Syk, and the range of each land value level value Syk corresponds to a value level. The range of land value level value Syk is [0, Sy1], (Sy1, Sy2], …, (Syk-1, Syk], and the value level includes value level 1, value level 2, …, value level k-1, and value level k, where the land value of value level 1 is less than the land value of value level 2, …, and less than the land value of value level k.

[0055] Set up GEP accounting module and accounting comparison module, conduct regular GEP accounting of land, and conduct in-depth correlation and comparative analysis of the GEP accounting values ​​of each period. Dynamically analyze the value of land through material product output, regulatory service function volume and cultural service function volume, and provide support for the long-term planning of land resources. It is applicable to various land types such as agricultural land, forestry land, and tourism land, and meets the management needs of different fields. The value of land can be more intuitively and significantly reflected through the division of value levels.
