What is the significance of developing forestry response to climate change? Need an answer urgently! ! !

On the issue of global climate change, forestry has aroused widespread concern in the international community. Therefore, it is particularly important to correctly understand the position and role of forestry in coping with climate change, which will play multiple positive roles in China's positive position in international negotiations on climate change, alleviating the negative impact of climate change and the sustainable development of forestry, and also help to clarify the development direction of forestry in China.

Forestry has a special function in dealing with climate change.

Carbon sink function of forest: As the main body of terrestrial ecosystem, forest has important functions such as regulating climate, preventing wind and fixing sand, conserving soil and water, absorbing and fixing atmospheric carbon dioxide, and producing oxygen. It is the largest carbon reserve and the most economical carbon absorber on land, and it is an important lever to maintain carbon balance in the atmosphere. Forests and forestry activities play an important role in measures to reduce greenhouse gas emissions and stabilize atmospheric carbon dioxide concentration. Scientific research shows that the average amount of carbon dioxide absorbed by the forest is 1 m3, and destroying and reducing the forest will increase carbon emissions. After 10 years, soil organic carbon decreased by 30.3% on average. According to the estimation of the United Nations Intergovernmental Panel on Climate Change, the global terrestrial ecosystem stores about 2.48 trillion tons of carbon, of which the forest ecosystem stores 65.438+0.10.5 trillion tons of carbon.

Economic functions of forests: In the principles of climate change mitigation and adaptation formulated by the United Nations, which came into effect in 1994, it is clearly stated that policies and measures to deal with climate change should be cost-effective and ensure global benefits at the lowest possible cost. Although there is a unified calculation result on the cost of reducing deforestation emissions at present, it is generally believed that the cost is much lower than industrial emission reduction, and the measures to reduce deforestation emissions have great potential to get quick results.

Therefore, developing forestry is an important measure to deal with climate change.
