Description

Technical Field

[0001] The present invention relates to the field of ecological economy and land resource management, and in particular to a method for determining the ecological value-added of a land parcel by combining the value of regulatory services and the characteristics of land use. Background Art

[0002] With the deepening of ecological civilization construction, the management and utilization of land resources are gradually shifting from the traditional economic benefit orientation to a sustainable model that takes into account both ecological and economic benefits. As an important tool for quantifying the contribution of ecosystem services in economic activities, ecological service value assessment has become an important basis for ecological compensation, land transfer and green finance. However, the existing technology has the following shortcomings in the accounting of land ecological value: First, the current ecological service value assessment method is usually based on static accounting, lacking a comprehensive analysis of the dynamic characteristics and spatial heterogeneity of ecological resources in specific plots and their surrounding areas. Secondly, different land uses have different demands and impacts on ecological services, but the existing methods do not fully consider the adaptability of land uses. Finally, traditional land valuation focuses more on market value and development potential, ignoring the important role of ecological service functions in the appreciation of land transfer.

[0003] Therefore, there is an urgent need for a method to determine the ecological value-added of land parcels that can comprehensively consider ecological service functions, land use characteristics and regional characteristics, so as to more comprehensively reflect the ecological value of the land and provide a scientific basis for the sustainable use of land resources and the construction of ecological civilization. Summary of the invention

[0004] The present invention aims to provide a method for determining the ecological value-added of land to be transferred, which can comprehensively adjust the service value, land use characteristics and regional ecological resource characteristics, scientifically evaluate the ecological value-added of land, and provide scientific support for decision-making in land transfer and related fields.

[0005] To achieve the above object, the technical solution of the present invention is as follows:

[0006] A method for determining the ecological value-added of a land parcel for sale comprises the following steps:

[0007] Step 1: Obtain the basic data of the target land parcel:

[0008] Obtain the area of ​​the target land parcel for sale;

[0009] Obtaining the unit area adjustment service value data of the target land parcel;

[0010] Obtain the lowest and highest ecological service value per unit area data for the area where the target land parcel is located;

[0011] Obtain the benchmark land price data for the area where the target land parcel is located;

[0012] Step 2: Calculate the ecological product value coefficient of the target land parcel:

[0013] The ecological product value coefficient is calculated using the unit area regulation service value. The formula is as follows:

[0014]

[0015] Where V is the ecological product value coefficient, unitless; E b Adjust the service value per unit area of ​​the target land parcel; E min The minimum ecological service value per unit area of ​​the area where the target land is located; E max The highest ecological service value per unit area in the area where the target land parcel is located;

[0016] Step 3: Determine the ecological factor compatibility coefficient and ecological realization potential coefficient of the target land parcel:

[0017] Obtaining the project type and land use of the target land parcel for sale, and determining the ecological factor compatibility coefficient of the target land parcel for sale according to the obtained project type and land use;

[0018] Obtain the potential content and ecological product value realization method of the target land parcel for transfer, and determine the ecological realization potential coefficient of the target land parcel for transfer based on the obtained potential content and ecological product value realization method;

[0019] Step 4: Calculate the unit price of ecological value-added gold for the target land parcel:

[0020] Based on the benchmark land price, ecological product value coefficient, ecological factor compatibility coefficient and ecological realization potential coefficient of the target land parcel, the unit price of ecological value-added gold is calculated according to the following formula:

[0021] P E =P o ×(A+F×V)

[0022] Where P E P is the unit price of ecological value-added gold for the land parcel to be transferred. o is the benchmark land price of the area where the target land parcel is located, A is the ecological realization potential coefficient of the target land parcel, F is the ecological factor compatibility coefficient of the target land parcel, and V is the ecological product value coefficient of the target land parcel;

[0023] Step 5: Obtain the ecological value-added fund of the target land parcel:

[0024] The total ecological value-added amount of the land to be transferred is calculated based on the area of ​​the target land to be transferred and the unit price of the ecological value-added fund.

[0025] Furthermore, in step 1, a county-level administrative unit is selected as the area where the target land parcel for sale is located.

[0026] Furthermore, the unit area adjustment service value data of the target land parcel for sale in step 1 is obtained from government departments and evaluated in combination with the actual use of the land parcel.

[0027] Furthermore, the benchmark land price data of the area where the target land parcel for sale in step 1 is located is obtained from government departments.

[0028] Furthermore, the calculation formula for the total ecological value-added amount of the target land parcel is:

[0029] Total ecological value-added amount = P E × plot area.

[0030] Furthermore, the ecological product value coefficient, ecological factor compatibility coefficient and ecological realization potential coefficient can be adjusted according to the ecological conditions and policy requirements of different regions to adapt to a variety of land types and use scenarios.

[0031] Compared with the existing technology, the present invention systematically constructs a scientific evaluation method for the ecological value-added of the transferred land by combining the ecological product value coefficient, the ecological factor compatibility coefficient and the ecological realization potential coefficient, and realizes the refined accounting from the regional ecological service characteristics to the specific land use adaptation. This method not only has high evaluation accuracy and flexible parameter setting, but also has significant versatility and can be applied to a variety of land types and use scenarios. It has important value in optimizing land transfer pricing, promoting the implementation of ecological compensation mechanisms, and supporting the development of green finance, and provides innovative technical support for the sustainable management of land resources and the construction of ecological civilization.
