In recent years, as carbon dioxide emissions have increased, the global climate has warmed, sea levels have risen, and various natural disasters have occurred frequently. In response to climate change, China has set goals to reach the peak of carbon dioxide emission by 2030 and achieve carbon neutrality by 2060. Forest carbon sequestration is one of the main ways to mitigate climate change, and forests, being the main body of terrestrial ecosystem, serves as important carbon storage. Studies have shown that for every cubic meter of forest growth, an average of 1.83 tons of carbon dioxide is absorbed and 1.62 tons of oxygen are released. Just like banks store cash, forests can store carbon dioxide through plant photosynthesis, which is completely environment-friendly and pollution-free. Therefore, forest carbon banks are one of the most cost-effective ways to deal with climate change. The forest in the urban park in the Lingang Special Area also has a contribution that cannot be underestimated.
It is estimated that the burning of one ton of standard coal produces about 2.25 tons of carbon dioxide, and an average acre of adult forest can absorb about 24.455 tons of carbon dioxide a year, which is equivalent to about 367 tons of carbon dioxide per hectare of forest.
Since the establishment of the special area, the overall forest coverage rate has increased by 1.5% compared to 2019. Among them, the park contributes about 30% of the forest area, and the average forest coverage rate of the park is about 60%. At present, the existing Second Ring Park Belt and the Dishui Lake Surrounding Lake Landscape Belt have a forest coverage area of more than 180 hectares. In addition to the under-construction Luligang, Huangrigang wedge-shaped green space and community park green space, the overall forest area of the main urban area is no less than 300 hectares. The annual average absorption of carbon dioxide is about 110,000 tons and the carbon bank is estimated to cost 3.3 million yuan.
Urban parks create ecological benefits
Experts point out that the rate of forest carbon sequestration is closely related to its age composition. Generally, forests can be divided into young forests, middle-aged forests, near-mature forests, mature forests, and over-mature forests. The carbon sequestration rate of young and middle-aged forests is relatively fast, while the growth rate of mature and overmature forests is reduced, and the absorption and release of carbon are basically balanced.
At present, the trees in the park in the special area are still in a stage dominated by young and middle-aged forests, and their growth is relatively fast. The complex park and forest ecological space in the special area create an urban forest landscape with complex landscape and functions. The rich forest structure further promotes the growth and development of trees and plays a significant role in the multiple measures to reduce greenhouse gas emissions.
A standard to improve quality and efficiency to help achieve carbon neutrality
In addition to continuing to expand the forest area, we must also consider improving the quality of forests and scientifically use and protect them.
All maintenance work in the urban parks of the special area requires meticulous management. In order to create a good public recreational environment, the special area is working hard to explore the methods and measures of refined green space management, and research and formulate refined management standards. The special area is set on scientifically maintaining the environment for the growth of seedlings, promote the rapid formation of trees in the park into forests, and effectively improve the level of green space conservation to help achieve carbon neutrality. The goal of national carbon peak and carbon neutrality is closely related to each of us. One less air conditioner, one more window, choosing low-carbon travel, or choosing to plant a tree, all have effects. After a day of studying and working, take some time to walk in the park in the special area. The “Carbon Bank” in the special area is thriving. Where do you want to go next?
