Description

Technical Field

[0001] The present invention relates to the technical field of ecological restoration, and in particular to a method for assessing the carbon footprint of an ecological restoration project over its entire life cycle. Background Art

[0002] As one of the most important means of optimizing and regulating ecosystems, ecological restoration project construction has played a significant role in improving the quality and stability of ecosystems. The ideas and concepts of ecological restoration projects have undergone profound changes in all aspects. Ecological restoration based on systematicity, integrity and stability is the direction of future development. Ecosystems such as soil, vegetation and other carbon pools also have huge carbon sequestration potential. Therefore, doing a good job in ecological protection, restoration and reconstruction, improving the carbon sequestration capacity of ecosystems, and further reducing emissions and increasing carbon sinks are equally important. Therefore, in the current ecological restoration projects, it is of great significance to evaluate the effectiveness of ecological restoration project construction from multiple objectives, multiple dimensions and multiple perspectives.

[0003] At present, when evaluating ecological restoration projects, the effectiveness and benefits of restoration are usually evaluated through microscopic or on-site experimental data. There is less research on the carbon emissions of social and economic activities during the construction process, and no consideration is given to the carbon emissions of the restoration process itself. Ecological restoration projects themselves have the dual attributes of social economy and natural ecology. The implementation object is the natural ecosystem, and the implementation behavior is the social and economic subject. Therefore, developing a carbon footprint accounting method for grassland ecological restoration projects based on the entire life cycle has become a technical problem that needs to be solved urgently.

[0004] At present, carbon emission methods for agricultural, pastoral and forestry areas in ecological restoration include IPCC carbon emission calculation method, inventory method, input-output method, etc. Carbon sequestration methods such as remote sensing monitoring and laboratory observation still have certain defects, such as mismatch of time and space scales and weak representativeness of monitoring data. However, these methods cannot evaluate the carbon footprint of a systematic project such as ecological restoration project throughout the process, and do not fully consider the project input and ecological benefit output.

[0005] The existing application number is 202410667547.0, which is a method, system, device and storage medium for assessing the carbon footprint of crops. Through this scheme, the carbon emission data of crops in each link can be quickly and effectively predicted, and the impact of these data on the total carbon emissions can be considered, so as to accurately predict the total carbon emissions of crops after maturity. The present invention can not only improve the efficiency and accuracy of the carbon footprint assessment of crops in a low-cost manner, but also formulate a target strategy for reducing carbon footprints based on accurate carbon footprint data, and formulate targeted emission reduction measures; however, the scheme does not clearly and in detail mention the carbon sequestration assessment method of crops. Even if the soil carbon sequestration method is mentioned in some parts, its calculation process lacks specific instructions and details, and it is difficult to provide users with clear operation instructions. This lack of detailed description may make it difficult to accurately assess the contribution of soil carbon sequestration in practical applications; at the same time, it ignores the important effect of crops as vegetation carbon sequestration, and fails to include this natural process in the carbon footprint assessment. This neglect weakens the consideration of the integrity of the natural attributes of agricultural production, which may lead to the assessment results of the carbon footprint of crops being not comprehensive and accurate.

[0006] The existing application number is 202311348321.6, which is a method and system for evaluating the carbon and nitrogen footprint of agricultural planting industry. Its purpose is to establish a standardized carbon and nitrogen database for agricultural planting industry; by identifying the source and sink process of carbon and nitrogen in agricultural planting industry, a standardized carbon and nitrogen database is established, and the input, circulation and output of carbon and nitrogen in agricultural planting industry are accurately calculated, and the carbon and nitrogen emissions and in-situ absorption capacity in the planting production process are quantitatively evaluated using the accounting results; this method combines life cycle assessment method, input-output method, material cycle method and other methods to calculate the carbon and nitrogen source and sink of agricultural planting industry, and comprehensively evaluate the carbon and nitrogen footprint and in-situ absorption capacity; but this program focuses on agricultural areas The technical solution of the carbon-nitrogen evaluation method for the crop industry is mainly aimed at the needs of agricultural areas, so some specific parameters and requirements of the pastoral system are not considered during the design; this limitation makes the application scope of the patent relatively narrow, and it is difficult to adapt to the carbon-nitrogen footprint evaluation needs of different types of regions; at the same time, although a variety of parameters and codes involved in the carbon-nitrogen evaluation method are listed, there is a lack of detailed description of the database construction process; this includes the lack of clarity on the sources of various data, and the lack of localization of parameters and the collection and application of field monitoring data; in the field of environmental accounting, localization of parameters and data based on field monitoring can more accurately reflect the region-specific carbon footprint characteristics.

[0007] Therefore, it has become a technical problem that needs to be solved urgently to propose a method for calculating the carbon footprint of ecological restoration projects over their entire life cycle, expand the scope of assessment, and achieve a comprehensive and integrated assessment from project construction to the end of ecological restoration to take into account both socio-economic carbon emissions and natural ecological carbon sequestration. Summary of the invention

[0008] In view of the above-mentioned deficiencies in the prior art, the present invention provides a method for assessing the carbon footprint of an ecological restoration project over its entire life cycle, aiming to establish a standardized and regionalized accounting database and method, to accurately account for the restoration construction and operation carbon emissions of ecological engineering projects and the ecological carbon fixation effects after restoration, and to comprehensively evaluate the ecological and environmental impact of project investment and the output of restoration benefits.

[0009] To achieve the above purpose, the technical solution adopted by the present invention is:

[0010] A method for assessing the carbon footprint of an ecological restoration project over its entire life cycle is provided, which comprises the following steps:

[0011] S1: Identify and acquire data on carbon sources and sinks during ecological restoration;

[0012] S2: Collect relevant parameters of carbon source and carbon sink data and compile inventory;

[0013] S3: retrieve carbon source and carbon sink data and related parameters, and perform carbon footprint accounting;

[0014] S4: Comprehensively calculate the carbon footprint and conduct a carbon benefit assessment; the carbon footprint accounting includes total carbon emissions and carbon sinks.

[0015] Furthermore, total carbon emissions include carbon emissions from material production, carbon emissions from transportation, carbon emissions from construction and carbon emissions from restoration operations, and carbon sinks include carbon sequestration in vegetation and soil.

[0016] Furthermore, the carbon emissions CE generated by material production 1 The calculation formula is:

[0017] CE 1 =∑AD i ×EF 1i

[0018] In the formula, i is the number of material types, AD i is the quality of the i-th material, which includes the building materials and the material inputs in the restoration process; EF 1i is the carbon emission factor per unit mass of the i-th material input;

[0019] Carbon emissions from transportation 2 The calculation formula is:

[0020] CE 2 =∑(D i ×M i ×P×EF 2 ×0.85+AM×EF 3 )

[0021] Where D i is the transportation distance of the i-th material; M i is the mass of the transported material; P is the fuel consumption per kilometer; EF 2 is the carbon emission factor of fuel consumed by transport vehicles; 0.85 is the conversion factor; AM is the number of livestock required for transport; EF ... 3 Emission factors for livestock transport;

[0022] Carbon emissions from construction CE 3 The calculation formula is:

[0023] CE 3 =∑(N i ×T i ×P Mi ×EF 4i +HL i ×EF 5 )

[0024] Where N i is the number of construction machinery such as excavators and cranes used in the construction of the i-th material, T i is the mechanical working time of the i-th material, P Mi is the power of the i-th material under mechanical operating conditions, EF 4i is the carbon emission factor during the mechanical operation of the i-th material; HL i is the manpower input in the construction process of the i-th material; EF 5 is the manpower carbon emission factor;

[0025] Carbon emissions CE generated during the restoration process 4 The calculation formula is:

[0026] CE 4 =∑(N j ×A j ×DS Mj ×EF 4j +HL j ×EF 5 )

[0027] Where j is the number of machine types in the repair operation, N j is the number of the jth type of machinery in the repair operation; A j is the operating area; DS Mj is the oil consumption under mechanical operation conditions; EF 4j is the emission factor of the jth mechanical operation process in the repair process; HL j is the manpower input of the jth machine in the repair process;

[0028] The calculation formula for vegetation carbon sequestration is:

[0029] CF 1 =∑A k ×t×C Vk

[0030] Where, CF 1 is the increment of vegetation carbon sink after restoration, A k is the area of ​​vegetation k, t is the project implementation period, C Vk is the annual net carbon fixation rate of vegetation k, which is obtained from experiments and theoretical calculations.

[0031] The calculation formula for soil carbon sequestration is:

[0032] CF 2 =∑A k ×t×C Sk

[0033] Where, CF 2 is the soil carbon sink increment after restoration, C sk is the soil carbon sequestration rate of vegetation type, which is obtained by experimental and theoretical calculations

[0034] Furthermore, step S4 specifically includes:

[0035] S41: Calculate the total carbon emissions and carbon sinks, where the calculation formula for total carbon emissions CE is:

[0036] CE=CE 1 +CE 2 +CE 3 +CE 4

[0037] The calculation formula of carbon sink CF is:

[0038] CF=CF 1 +CF 2

[0039] S42: Carbon benefit assessment: When the difference between the carbon sink CF and the total carbon emissions CE is greater than zero, it indicates a carbon surplus for the entire ecological restoration project; when the difference between the carbon sink CF and the total carbon emissions CE is equal to zero, it indicates a carbon balance for the entire ecological restoration project; when the difference between the carbon sink CF and the total carbon emissions CE is less than zero, it indicates a carbon loss for the entire ecological restoration project.

[0040] Furthermore, when the vegetation type at the ecological restoration site is alpine meadow, the calculation formula of the carbon sink CF in step S4 is:

[0041]

[0042] In the formula, Δ Y is the yield increase before and after grassland restoration; DF is the dry-wet ratio; s is the root-to-shoot ratio; C1 and C 2 Carbon content of alpine meadow vegetation.

[0052] S22: Obtain the local vegetation and soil carbon sequestration rate based on local vegetation types and restoration patterns;

[0053] S23: Construct a carbon source and carbon sink database, which includes a basic database and a parameter database. The basic database includes the basic information and data in step S1, and the parameter database includes carbon emission factors, vegetation and soil carbon fixation rates, and warming potential.

[0054] Furthermore, the carbon emission factor is determined based on the China product life cycle greenhouse gas emission coefficient database and reference values ​​in material-related literature.

[0055] Furthermore, local vegetation and soil carbon sequestration rates were obtained from simulated monitoring and remote sensing data experiments using vegetation-soil models.

[0056] The beneficial effects of the present invention are:

[0057] 1. The calculation theory proposed in this plan integrates the carbon emissions of the social and economic system and the carbon sequestration effects of soil, vegetation, etc. in ecological engineering construction, analyzes the carbon emissions and carbon benefits of the entire life cycle of ecological engineering implementation, establishes standardized and regionalized accounting databases and methods, and accurately calculates the restoration construction and operation carbon emissions of ecological engineering construction and the ecological carbon sequestration effects after restoration, which is conducive to a comprehensive assessment of the ecological and environmental impact of project investment and the restoration benefit output.

[0058] 2. This plan proposes a comprehensive carbon emission accounting method for ecological restoration projects based on the full life cycle assessment. It not only evaluates the carbon emissions of ecological restoration projects during their life cycle, but also quantifies their carbon fixation effects, thereby achieving a comprehensive and accurate assessment of the carbon footprint of ecological restoration projects.

[0059] 3. This plan focuses on the actual localized accounting parameters of ecological restoration projects and the data accounting combined with the field monitoring database. It pays special attention to the implementation of localized carbon emission accounting for ecological restoration projects in different regions, and makes full use of the data in the field monitoring data to ensure the accuracy and regional applicability of the accounting results. By combining local actual conditions and monitoring data, the proposed accounting method can better reflect the actual carbon emissions and carbon fixation effects of ecological restoration projects, and provide technical support for the formulation of green and low-carbon ecological restoration plan strategies.
