Description

Technical Field

[0001] The patent of this invention relates to the field of carbon neutrality technology, and specifically to a GEP assessment and carbon fixation and sequestration system for artificial forest ecosystems. Background Art

[0002] Gross Ecosystem Product (GEP) is the sum of the economic value of the final products and services provided by the ecosystem for human survival and well-being. The concept of Gross Ecosystem Product (GEP) was proposed to establish a statistical and accounting system that corresponds to GDP and can measure the good state of ecology. Since the Industrial Revolution, the increase in greenhouse gas emissions has led to global warming and climate change, and its emissions are crucial to solving the climate crisis.

[0003] However, existing studies have paid little attention to the GEP accounting and evaluation of artificial forest ecosystems and the research and application of carbon sequestration and sink models. Therefore, it is an urgent and realistic problem for us to clarify the key issues in the construction of timber forests and economic forests, help realize the value of ecological products, and transform the location advantages of forest resources into realistic carbon sink functions and forestry ecological industry advantages. Based on the precise accounting technology system, a GEP accounting framework system is constructed, and considering the problems existing in artificial forest management and the limitations of available land space, the management is transformed from single timber management to multi-objective sustainable management of forest ecosystems. Therefore, based on GEP accounting, clear evaluation standards and criteria can be provided for the sustainable production and operation and optimized management of artificial forests. Artificial forest ecosystems are an important part of forest ecosystems. The construction of an artificial forest GEP evaluation system helps realize the transaction and circulation of ecological value products. However, how to improve the biodiversity and forestland productivity of artificial forests and maximize the economic and ecological benefits of artificial forests is one of the important issues in the development of artificial forests.

[0004] In recent years, scholars at home and abroad have conducted a lot of research on carbon sequestration and carbon sink enhancement, but there are still many problems, such as the existing stock of forest ecosystem carbon pools, carbon sequestration rate and its uncertainty, the stability and sustainability of carbon sink function need to be evaluated, the formation and stabilization mechanism of soil organic carbon pools in forest ecosystems is still unclear, and the forest ecosystem carbon sink enhancement potential and risk assessment still need to be strengthened. The low productivity of my country's artificial forest ecosystems, unclear carbon sink formation mechanism, and unclear relationship between productivity and carbon sink function are key issues that restrict the sustainable development of artificial forests. Summary of the invention

[0005] In response to the problems in the prior art, the present invention provides a GEP assessment and carbon sequestration and sink enhancement system for an artificial forest ecosystem, which improves the biodiversity and forest productivity of artificial forests, maximizes both the economic and ecological benefits of artificial forests, and solves the key problems that restrict the sustainable development of artificial forests.
