Realize the great role of carbon neutralizing forests release date: Source: people people people to deal with climate change, China has put forward such target commitments as "strive to reach the peak of carbon dioxide emissions by 2030, strive to achieve carbon neutralization by 2060" and "by 2030, China's carbon dioxide emissions per unit of gross domestic product will be reduced by more than 65% compared with 2005"; The central economic work conference also takes "carbon peak and carbon neutralization" as the key task to be done well in 2021

from now on, this edition will launch a series of reports on "beautiful China · carbon reduction and emission reduction in action", focusing on forest carbon sink, marine carbon sequestration, industrial energy conservation and emission reduction, clean energy development, etc., to show China's efforts to achieve the new emission reduction goals

recently, zhangguobin, a third-class researcher from the climate division of the ecological Department of the State Forestry and grass administration, was busy and excited: "in response to climate change, China has put forward a new goal by 2030, in which the forest stock will increase by 6billion cubic meters compared with 2005. Forest carbon sequestration will play an increasingly important role in achieving the carbon neutrality goal."

zhangguobin said that the status and role of forestry and grassland in coping with climate change have been raised to a new level. As a forestry and grassland worker, he feels both great and glorious mission. "At present, around the new goals, we are studying and formulating plans and implementing specific goals in terms of expanding forest area, improving forest quality, scientific protection and utilization of WDS (3) recommendation index of Jinan gold testing recommendation model"

Forest carbon sequestration is one of the main ways to mitigate climate change. In recent years, China has carried out large-scale land greening actions. At present, there are two main ways to mitigate climate change: one is to improve energy efficiency, reduce energy consumption and reduce carbon dioxide emissions in the industrial and energy fields, that is, to reduce emissions; Second, protect and repair forests, grasslands and wetlands, and increase the absorption of carbon dioxide, that is, carbon sequestration

"just as banks store cash, forests can store carbon dioxide through plant photosynthesis." Zhujianhua, associate researcher of the Institute of forest ecology and environmental protection, Chinese Academy of Forestry Sciences, introduced that after photosynthesis and absorption of carbon dioxide by plants, it cannot be completely stored, and some will be released with the respiration of plants and soil; The death of plants, fires, diseases and pests, logging, etc. will also lead to the release of some carbon from forests. The remaining stored carbon dioxide is called carbon sink

as the main body of terrestrial ecosystem, forest is the largest carbon pool in the system. Forest carbon sink is also one of the economic and effective ways to deal with climate change. Zhujianhua introduced that the natural process of forest carbon sequestration and utilization does not need a high cost, and has ecological benefits such as protecting biodiversity, conserving water sources, preventing wind and fixing sand

China attaches great importance to forest carbon, which is also the role of the Chinese Communist Party in coping with climate change one day after the 120th anniversary of Mao Zedong's birth. As early as 2009, China proposed to increase the forest volume by 1.3 billion cubic meters by 2020 compared with 2005; In 2015, it was proposed that by 2030, the forest volume will increase by about 4.5 billion cubic meters compared with 2005

in recent years, China has carried out large-scale land greening actions to comprehensively protect natural forests and expand the scale of returning farmland to forest and grassland. Up to now, the national forest coverage rate has reached 23.04%, and the forest volume has exceeded 17.5 billion cubic meters, an increase of more than 4.5 billion cubic meters over 2005. "The forest volume has exceeded the 2020 target, and the target of increasing by about 4.5 billion cubic meters in 2030 has been achieved ahead of schedule." Introduction by zhangguobin

China's forest area and forest volume have maintained double growth for more than 30 years.

experts pointed out that the rate of forest carbon sequestration is closely related to its age composition. General forests can be divided into young forests, medium-aged forests, near mature forests, mature forests and over mature forests according to age. The carbon sequestration rate of young and middle-aged forests is relatively fast, while the carbon absorption and release of mature and over mature forests are basically balanced due to the decline of growth rate

against the backdrop of the overall decline of global forest resources, China's forest coverage has increased from 12.7% in the early 1970s to 23.04% at present. The forest area and forest volume have maintained double growth for more than 30 years. "Through large-scale afforestation and vegetation restoration, at present, China's forests as a whole are mainly young and middle-aged forests, which grow vigorously, help to improve the carbon sink intensity of China's terrestrial ecosystem, and play a significant role in the multiple measures of greenhouse gas emission reduction." Zhujianhua said

a research result released by the Chinese Academy of Sciences in 2018 shows that China's terrestrial ecosystem has been playing an important role in carbon sink in the past few decades. From 2001 to 2010, the terrestrial ecosystem has an average annual carbon sequestration of 201 million tons, equivalent to offsetting 14.1% of China's carbon emissions from fossil fuels in the same period; Among them, forest ecosystem is the main body of carbon sequestration, contributing about 80% of carbon sequestration

the national forestry and grass administration, in cooperation with the Ministry of ecological environment, has systematically calculated the carbon sink in combination with the preparation of China's national greenhouse gas inventory. Liudongsheng, deputy director of the State Forestry and grass administration, said that at present, China's total carbon reserves of forest vegetation have reached 9.2 billion tons, and the average annual increase in forest carbon reserves is more than 200 million tons, equivalent to 700 to 800 million tons of carbon sink

in China's new climate action goals, the increase of forest volume in 2030 compared with that in 2005 will increase from about 4.5 billion cubic meters to 6billion cubic meters. "It is estimated that for every 100million cubic meters of increase in forest volume, 160million tons of carbon dioxide can be fixed." Xuhuaqing, director of the National Center for strategic research and international cooperation on climate change, said that we need to make a lot of efforts to achieve the new goals

in addition to expanding the forest area, we should also improve the quality, protect and utilize scientifically

how to achieve the new forest stock target and increase the forest carbon sink capacity? Zhujianhua suggested that to expand the forest area, it is also necessary to improve the forest quality, protect and utilize scientifically

"according to the assessment, the maximum potential of China's forest coverage is likely to reach 28% - 29%. At present, about 30million hectares of land available for afforestation have not been established to be oriented by professional ability. In addition, there are more than 40 million hectares of land available to expand the forest area in addition to the land for returning farmland to forest and grassland." Zhujianhua said that under normal circumstances, the average forest volume per hectare in China is only more than 90 cubic meters. It is necessary to strengthen forest management, take forest tending and other measures, and establish a healthy, stable and efficient forest ecosystem

"to protect the existing forests, reducing deforestation means reducing carbon dioxide emissions, including reducing forest death and forest degradation caused by fires, diseases and pests, which is also an important path to increase forest carbon reserves." Zhujianhua said

"coping with climate change is a major issue that China has committed to the international community. We will organically combine land greening with coping with climate change." Liudongsheng said that at the same time, the forestry and grass departments will also improve the carbon sink of grasslands and wetlands, vigorously develop biomass energy, and play an increasingly important role in achieving the goal of carbon neutrality
