Currently, climate change, which is characterized by warming, is taking place around the world. The main reason is that since the Industrial Revolution, human activities such as large-scale burning of fossil fuels and deforestation have caused excessive emissions of greenhouse gases, mainly carbon dioxide, into the atmosphere.
In order to prevent climate warming from adversely affecting human survival and ecosystems, the international community has formulated the United Nations Framework Convention on Climate Change and the Kyoto Protocol. It is emphasized that human beings should reduce the emission of greenhouse gases into the atmosphere and increase the removal of greenhouse gases from the atmosphere in order to stabilize the concentration of greenhouse gases in the atmosphere, slow down the rate of climate change, and avoid irreversible negative impacts on human beings and natural ecosystems.
As defined by the United Nations Framework Convention on Climate Change,will "processes, activities and mechanisms for removing carbon dioxide from the atmosphere.""Call it a "carbon sink".
Forests are the main body of terrestrial ecosystems. Forest plants absorb carbon dioxide through photosynthesis and release oxygen, sequestering atmospheric carbon dioxide in the form of biomass in vegetation and soil, a process and mechanism that actually removes carbon dioxide that has already been emitted into the atmosphere. As a result, forests function as carbon sinks.
Moreover, the cost of absorbing fixed carbon dioxide through measures such as afforestation and forest protection is much lower than that of industrial emission reductions. All in allForestry activities with the main purpose of giving full play to the carbon sink function of forests, reducing the concentration of carbon dioxide in the atmosphere, and slowing down climate warming are generally referred to as carbon sink forestry. Although carbon sequestration forestry is closely related to traditional forestry, it is a further deepening of the function of traditional forestry.
The development of carbon sequestration forestry should include the following meanings:
1) The development of carbon sequestration forestry is always linked to climate changeInternational and domestic policies are closely linked, which should be in line with the requirements of sustainable economic and social development of the country and the national strategy to respond to climate change.
2) In the process of carbon sequestration forestry, not only the accumulation of carbon sequestration should be considered, but also the contribution of project activities to improving the stability, adaptability and overall service function of forest ecosystems, and promoting biodiversity conservation, watershed protection and community development.
3) Carbon sequestration forestry should be carried out on the carbon sequestration accumulated by the projectMetering and monitoringto demonstrate a real contribution to climate change mitigation. Therefore, it is necessary to formulate a technical support system that conforms to international rules and the actual situation of China's forestry.
4) The development of carbon sequestration forestry should be relied uponMarket mechanisms and legal instruments, through carbon sinks to obtain income, promote the development of forest ecological service market, improve the economic benefits of afforestation, mobilize more enterprises and social forces, and participate in forestry actions to respond to climate change.
Based on the above understanding, carbon sequestration forestry can be further summarized as:In accordance with the national strategies and sustainable development principles of various countries to address climate change, with the goal of increasing the carbon sink function of forests and mitigating global warming, comprehensively use market, legal and administrative means to promote forestry activities of forest cultivation, forest protection and sustainable management, and improve the overall carbon sequestration capacity of forest ecosystems; At the same time, enterprises and citizens are encouraged to actively participate in afforestation and sink enhancement activities, demonstrate social responsibility, and improve citizens' awareness of climate change and climate protection; Give full play to the function and role of forestry in responding to climate change, and promote sustainable economic, social and environmental development.
Although carbon sequestration forestry is still a relatively new term for most Chinese people, China has attached great importance to the restoration and protection of forest vegetation for many years, making China the country with the largest area of planted forests in the world. This is actually an initiative to develop carbon sequestration forestry. China's large-scale afforestation over the years has not only increased China's forest area and stock, but also absorbed and fixed a large amount of carbon dioxide.
The development of carbon sequestration forestry has been included as an important measure in China's National Plan to Address Climate Change. The state expands the forest area through afforestation; strengthen forest management and improve the quality of existing stands; intensify the protection of wetlands and woodlands; development of forest-related biomass energy; prevention of forest fires, pests and diseases; Control illegal expropriation of forest land and indiscriminate logging, and further develop carbon sequestration forestry.
While enhancing the overall carbon sequestration capacity of forest ecosystems, reducing the concentration of carbon dioxide in the atmosphere, and slowing down the trend of global warming, it will make positive contributions to national climate and ecological security, and promote comprehensive coordination and sustainable development of economy and society.
